The principal aim was to assess the environmental perception of the fishermen, and implement educational activities, on an island in Brazil. Twelve people between the ages of 23 and 63 were interviewed, of whom 75% were male, and 58.33% did not complete their elementary education. Regarding social benefits, 33.33% receive a family allowance and 16.66% receive the so-called 'green allowance' (financial assistance to extremely poor families who live in areas of environmental preservation). Fishing remains the main economic activity (58.73%). The most common types of fishing gear are the 'zangarias' (41.66%) and 'muruadas' (41.66%), used to catch white shrimp (Litopenaeus schmitti), the main resource traded on the island (83.33%). All those interviewed reported a change in the size and weight of the catch in recent years (100%), and 75% attribute this to the types of trap used. Talks, films and booklets, as environmental education activities, contributed to community awareness. The population is familiar with the effects of fishing traps, and shows an interest in changing the situation.

O objetivo principal foi avaliar a percepção ambiental dos pescadores e implementar atividades educacionais, em uma ilha no Brasil. Doze pessoas entre as idades de 23 e 63 anos foram entrevistadas, das quais 75% eram do sexo masculino, e 58,33% não completou seu ensino fundamental. Em relação aos benefícios sociais, 33,33% recebem o Bolsa Família e 16,66% recebem o chamado "Bolsa Verde" (assistência financeira a famílias extremamente pobres que vivem em áreas de preservação ambiental). A pesca continua a ser a principal atividade econômica (58,73%). Os tipos mais comuns de artes de pesca são as 'zangarias' (41,66%) e 'muruadas' (41,66%), utilizadas para capturar camarão branco (Litopenaeus schmitti), o principal recurso comercializado na ilha (83,33%). Todos os entrevistados relataram uma mudança no tamanho e peso da captura nos últimos anos (100%) e 75% atribuem isso aos tipos de armadilhas utilizadas. Conversas, filmes e cartilhas, como atividades de educação ambiental, contribuíram para a conscientização da comunidade. A população está familiarizada com os efeitos das armadilhas de pesca e mostra interesse em mudar a situação.

The vast expanse of the Maranhão coastline and its immense biological diversity are favourable to the occurrence of multiple fishery resources, which are exploited by a large variety of equipment and types of fishing, from small-scale fishing without boats, or the use of skiffs or sailing boats, to large vessels (Isaac et al., 2006).

In recent decades, artisanal fishing has been growing due to the setting up of housing in coastal areas, free access to resources, and reduced control and supervision, but mainly due to the lack of other employment opportunities for the riverine population (Haimovici, 2011). According to Almeida et al. (2006), in the State of Maranhão, 15% of the active population is engaged in fishing, and this has led to conflicts between conservation of the resources and the environment, and the economic development of the population (Haimovici, 2011). However, in order for fishing in Maranhão and in other regions of Brazil not to collapse, institutional management and conservation measures have been implemented, including the creation of Environmental Protection Areas (EPA) and Extractive Reserves (EXRES), with a view to maintaining the natural resources and to integrating man and the environment. It is therefore not enough to consider only the biological and ecological characteristics of these resources, it is also necessary to consider the social and economic aspects involved in exploiting the resources. Through multidisciplinary and integrated studies, it is possible to better understand the economic role of fishing and its impact on the environment (Almeida, 2008).

One of the most common environmental impacts of fishing activities comes from discarding non-target species (Alarcon et al., 2009). This type of practice poses a threat, both to the stocks of target species and to the populations of discarded species that have no attractive commercial value (Zhou et al., 2015). Environmental education, directed towards the resolution of environmental problems as an added dimension to the content and practice of education, can contribute to the minimisation of such impacts.

Environmental perception is a tool to measure and evaluate the environment in which an individual works, in addition to directing their activities and way of life (Evangelista-Barreto, 2014), allowing to evaluate how the community visualizes local aspects related to the exploration of the natural resources, effects of human actions on the environment, benefits derived from biodiversity conservation, and others. According to UNESCO (1973), the different perceptions of culturally distinct individuals, or socioeconomic groups that perform different social roles, are one of the barriers to the protection of natural environments. Therefore, to evaluate the environmental perception to implement environmental education activities is the most effective way of implementing public policies related to the environment and, consequently, to communities that have natural resources for their subsistence (Oliveira and Corona, 2008).

Therefore, using this knowledge to develop community awareness measures and providing the information needed to implement sustainable fisheries and care for the environment, whether for adults or children, is the most effective way to practice environmental education in traditional communities, because it will be based on the causes and motives described by the social actors themselves and in the constructive thinking of suitable methodologies for satisfactory results (Cunha & Leite, 2009).

Based on these ideas, the aim with this work was to assess the environmental perception of fishermen concerning the impact of 'zangaria' (fixed-trap) fishing, as an aid to the implementation of educational activities for fisheries management in the EXRES of Cururupu.

Material and Methods

1. Study area

The municipality of Cururupu is located on the western coastline of the State of Maranhão in Brazil, and has an area of ​​495 km². It comes under the Brazilian System of Conservation Units, with the region included and authorised as an Environmental Protection Area (The so-called Reentrâncias Maranhenses) and Extractive Marine Reserve (Costa et al., 2006).

Created by Presidential Decree on 2 June 2004, the Marine EXRES of Cururupu contains around 185,046 ha, and is part of the Brazilian marine biome, comprising a diverse fauna with almost 1,300 species of fish, 19 of which are endangered and 32 in a state of decline (ICMBIO, 2016). It is made up of 15 islands with an area which is used by traditional extractive populations: Mangunça, Caçacueira, São Lucas, Valha-me-Deus, Guajerutiua, Lençóis, Ponta Seca, Porto Alegre, Retreat, Bate-Vento, Porto do Meio, Mirinzal, Iguará, Beiradão and Peru, the last serving as the study area for this work (Figure 1).

2. Field activities

The researchers initially presented the project to the deliberation council of the EXRES to obtain authorisation to carry out the work, and later gave a talk to the residents of Peru Island (Cururupu, in the State of Maranhão) to present the project and to propose a partnership with the residents in carrying out each of the activities, so as to seek solutions for sustainable fishing and to generate information for fisheries management. The talk was also aimed at clarifying technical terms and the results which would be obtained with a scientific project (the breeding of economically important species and the determination of fish diversity in the region) carried out in parallel with this environmental education project under SISBIO license No 47170-1, and with the permission of the Committee for Ethics and Animal Experimentation of the Maranhão State University (Protocol No 016/2014).

In February and March of 2015, to analyse environmental perception in the community, qualitative-quantitative approach was used (Lefèvre and Lefèvre, 2005, Kirschbaum, 2013), seeking a perspective of the social and economic situation, as well as assessing the way the community viewed environmental impacts related to fishing such as wastage and bycatch, solutions for reducing the size of the catch, and the use of selective fishing gear. At this stage, semi-structured questionnaires (Diniz et al., 2011) were used with a sample size of 12 individuals, considered by the community as "key informants", since they demonstrated knowledge acquired locally, either by observation, use or exploration (Sousa et al., 2015). To select the informants, the snow-ball technique was used, in which a first key informant indicates the subsequent one, and so on (Atkinson & Flint, 2001). The inclusion criteria included people of both sexes that worked with fisheries. The sample number represents 25% of the island's total population and the chosen informants were nominated by the community itself, including island councilors, as the most appropriate people to discuss and report on the local situation.

For the data analysis, a database was created in Microsoft Excel software, where frequency tables that were generated indicated the representativeness of the informants' opinion. Besides, the interviews were recorded and analyzed later, and the most representative discourses were transcribed in original language.

After obtaining the results, an educational booklet was produced, in the form of comics and in accessible language, in which the information obtained was made available in order to keep the population aware of their role in conserving resources. Moreover, the film "Mônica's Gang - A Plan to Save the Planet" (Sousa, 2011) for children, which portrays the conservation of natural resources in a didactic and accessible way, was broadcast. Although the interviews were not conducted with the children, this activity was included based on what was concluded about the knowledge that is transmitted from the parents to the children in the community.

The identification of participants was kept secret, with their names not included in the databases, ensuring the anonymity and confidentiality of the information. We obtained the participation and consent of those involved after clarifying the purpose of the research, their agreement expressed by Informed Consent Form.


1. Establishing the initial aims of the research

At the initial talk, was counted on the participation of the residents, who raised important questions, such as the return of results to the community, benefits of the scientific research (concerning fish diversity in the region and determination of the reproductive period of four economically important species) and the position of the organs responsible (Figure 2).

Figure 2 Initial talk to the Peru Island community, Cururupu EXRES, Maranhão, Brazil. 

2. Profile of the community under investigation

The age of the informants ranged from 23 to 63, with a predominance of individuals in the 35-45 age group, and those >55 (33.33%) who had lived on the island for over 20 years. As seen in several surveys related to fishing, the male sex predominated, representing 75% of those interviewed.

The lack of representation of the female sex can be verified by the testimony of one resident when asked about women's involvement in fishing activities:

"[...] When he gets back from the sea, I help him lay the shrimp in the sun, take them out of the sun... actual fishing, no. Sometimes as I said, I go down to the water's edge."

(Female resident, Peru Island, 51)

In relation to schooling, 58.33% of those interviewed had not completed elementary education. Most of those interviewed receive no kind of social benefit, and among those who do, the Family Allowance was the most represented, at 33.33% (Table 1).

We noted a great appreciation of social benefit by the respondents, who said that the benefit came in useful when helping to pay expenses, since fishing is an unstable source of income, where some periods are more productive than others are.

Almost 60% of those interviewed work in fishing, an indication that this is the principal economic activity on Peru Island.

Among the types of fishing gear used by the fishermen are the so-called 'zangaria'1, 'tarrafa'2, 'curral'3, 'muruada'4 e and 'puçá'5. The 'zangarias' (41.66%) and the 'mouaries' (41.66%) are the most common types of fishing gear. We noticed that the fish are used mainly for personal consumption or sold at a lower value, and that shrimp is the most commercially valued product (83.33%), explaining the results found for the fishing gear.

The most traded species according to the fishermen are White shrimp (Litopenaeus schmitti), King Weakfish (Macrodon ancylodon), Coco sea catfish (Bagre bagre), Whitemouth Croaker (Micropogonias furnieri), Crucifix sea catfish (Sciades proops), Tripletail (Lobotes surinamensis), Parassi mullet (Mugil incilis) and Common Snook (Centropomus undecimalis).

Family income, for the most part, does not exceed the minimum wage (41.67%), but a large number explained that there was no way to state that with conviction (Table 2) since the monthly income from fishing activities is highly variable due to fluctuations in the product, ranging from the minimum wage (BRL 788.00 - USD 291.85 [in 2015]) to four minimum wages (BRL 3,152.00 - USD 1,167.40 [in 2015]).

Regarding perceived changes in the size and weight of the fish, 100% of the respondents said that these aspects have changed over the years. A total of 69.2% related this to the intense exploitation of resources due to the use of selective fishing gear and the removal of juvenile individuals that have not yet seen an increase in weight or length, and are therefore considered unsuitable for consumption.

"The change is because they are catching very small fish... all kinds of fish ... there is no time to grow, they catch them early to sell. As I say, there is a lot of fish."

(Resident, 37)

Around 75% of those interviewed said that the traps used by the community cause damage, and that the weighted nets6 used by fishermen from neighbouring communities end up hampering fishing in the Peru Island community.

On the other hand, some respondents also consider the trawl net and high trap (zangaria alta) to be harmful types of fishing gear.

"Man, it causes damage, right, because actually the fixed trap... it always kills both the big and small fish, right?! And other types of fishing, the high trap ... that's a really high net. Whatever is there is caught. We don't have it here, but they come from another places to fish here, understand?! They put it right at the edge of the mangrove".

(Resident, 33)

"It's bad. Fishing with nets, they're doing away with the fish there in the river. Trawling ... causes a lot of damage here. They trawl the river, there are times we go and don't even catch enough to eat. They're "squeezing the fish out", as we say here".

(Resident, 39)

Regarding a possible solution to the visible reduction in fish, 25% of respondents pointed to the closed season, and another 25% stated that the problem has no solution. Some of those interviewed pointed to a reduction in the number of nets and a change in the current closed season as possible solutions.

Currently, the closed season in the Cururupu EXRES is from June to August; this corresponds to the migration of the sardines and not to the reproductive period of the fish.

The residents themselves stated during the interviews that June to August is the wrong period as that is when the fish are of a good size for fishing.

"They should have come to do the research, because the one time that is good for fishing, they are prohibiting it; it's the wrong time."

(Female resident, 31)

One resident also drew attention to better enforcement of the regulations with punishment for those who disagree:

"Besides having the ban when you can't fish, we believe there has to be control anyway, and punishment for those people who 'may disagree' with the management agreement in this notice that arrived. Because if I call a meeting of the community to get rid of a fisherman's net from here, very soon we are going to have trouble, and at the moment not even the law gives supports us, it doesn't punish that fisherman, it won't help at all. So we need control and punishment for anyone who disagrees with the management agreement."

(Resident, 23)

A total of 81.8% of those interviewed said that they did not notice any type of pollution on the island; this result being directly related to receipt of the Green Allowance benefit (financial assistance to extremely poor families who live in areas of environmental preservation). Regarding guidance on the minimum catch size for the most traded fish, around 50% said that there had been a meeting where this information was passed on, and 50% say that there is no regulation for a minimum catch size (Table 3).

Table 3 Environmental perception data of the fishing community of Peru Island, Cururupu EXRES, Maranhão, Brazil. 

Aspects/Questions Response Percentage (number of individuals/total)
Are the traps used by the community harmful? Yes 75.00% (9/12)
No 8.33% (1/12)

Don't know 33.33% (4/12)
Is there any kind of guidance on minimum catch size? Yes 50.00% (6/12)
No 50.00% (6/12)

In an attempt to get them to reflect on the environmental problems that may affect or are affecting the island, we asked how they imagined the environment in which they lived 20 years from now. The majority answered that the situation would be more critical than it is today and that resources would be more scarce.

"That's right ... if no one is worried and there is not even the law to take the necessary measures, I think we probably won't have as much as we had before; even today I don't see so much anymore, we only have something now through divine help. But if you say it's because of our own awareness, that it's improving because of us, because we are taking care of the reservation, then it's a lie because that's not happening. It's the old question 'only the smartest survive'".

(Resident, 23)

3. Didactic tools used with the community

At the end, we gave the children and adults an educational booklet with information obtained scientifically and from actions carried out throughout the year, which serves as a basis for current and future fishing activities, and to reflect on how each one can contribute to the sustainability of Peru Island. The contents include fish diversity in the region, information on the reproductive biology of four economically important species, the final destination of the specimens taken to the laboratory, photographs, reflections of the residents themselves during the interviews, and finally, a look at the local situation 10 years from now with the collaboration of the community (Figure 3).

Figure 3 Part of the educational booklet produced from results obtained during the project. Graphic design and illustration: Yuri Almeida. 

After the screening of the film "Monica's Gang - A Plan to Save the Planet", it was noticed that the children had learned important lessons regarding the disposal of solid wastes and contaminants in the aquatic environment and the consequences of that for fishing. To evaluate this learning, one wondered what would be done with plastic cups and bags used for food and beverage consumption during the film. They replied that they would apply the logic of the three R's that was taught during the film: reduce and reuse, using only a glass; and recycle, to produce some kind of garnish or handicraft.


Throughout the research, it was noticed that the population is aware of the effects caused by the fishing traps and show interest in transforming this reality. This perception of the fishing community was the initial step so that the actions of environmental education could collaborate in the process of knowledge construction, conservation of fishing resources, and sensitization of local social agents.

The longer the time lived in an area, the greater the level of knowledge and familiarity with that area, therefore, people of more advanced age are best suited to talk about local activities and the environment as a whole. According to Silvano and Begossi (2012), there is an accumulation of knowledge with the passing years, so that older people tend to know more about matters of interest to the community, and are considered the most suitable because of that knowledge.

Because fishing is still a traditionally male activity, we saw a greater representation of men. Similar results were reported by Santos et al. (2011) in the fishing community in the town of Raposa, Maranhão, stating that this pattern is the result of the need for great physical effort in fishing activities and of the danger, both of which end up being limiting for women. According to Costa (2009), only now are women beginning to show interest in the activity together with their husbands, sometimes leaving off other activities such as handicrafts or even household chores. However, their main function is still to clean the fish, organise the gear and prepare the food (Knox and Firme, 2016).

The results found for level of schooling may be related to the geographic isolation imposed on the inhabitants of an island, or to the economic conditions, where children and grandchildren end up starting fishing activities early, either to help or to support the family. The results found by Santos et al. (2011) in the town of Raposa, support this, since the author found a higher level of schooling among the younger fishermen, and related this to the proximity of the state capital, São Luís, where transportation is regular and more schools are available.

The fact that fishing is still the most predominant activity in the community can be explained by the richness and abundance of the resources occurring at the site, and by the conditions, which are favourable to fishing. However, fishing is considered an activity of unstable return, and fishermen and their families therefore supplement their income with financial aid provided by the government and with other types of activities, such as tourist transport and the sale of handicrafts. This way of working in fishing communities is common in other regions of the Amazon (Ceregato and Petrere Jr., 2003, Cardoso et al., 2004, Ruffino, 2005, Lima et al., 2012). Furtado (1993) states that artisanal fishermen are known for being multitalented, due to the extensive range of work they carry out daily, where they mix several activities so as to guarantee the sale of various products and generate a minimum income.

Shrimp as the target product is directly related to the types of fishing gear used and the size of the net opening. This practice may have future impact on the region, since fish of all sizes are caught, including juveniles, which end up not being used for sale or consumption, and are discarded on a large scale (Alarcon et al., 2009, Leitão et al., 2014, Klautau et al., 2016).

As the "zangaria" (fixed trap) is already prohibited in the country, with Maranhão being one of the only states where it is still allowed (with activities suspended from June to August), the fear of a possible ban may have influenced the questions on harmful fishing gear. According to Pereira (2008) and Golden et al. (2016), the daily need for food is the main reason why fishing is increasingly more intense. The shortage of resources leads to the use of nets of a finer-mesh with the aim of capturing smaller species to achieve results similar to earlier scenarios. As a result, there is greater damage to the environment, compromising stocks and jeopardising future catches.

The closed-season insurance benefit, implemented by the Ministry of Labour and Employment, where fish, shrimp and lobster fishermen receive a minimum wage not to fish during the reproductive period of the species (Cavalcante et al., 2013), is not received by any of those interviewed. Difficulties in delivering and checking documents are the main reasons for the delay in implementing this aid.

Adequate cleaning of the environment is related to the Green Allowance benefit received by the residents, encouraging them to carry out collective clean-ups and meetings to organise the disposal of garbage. The Green Allowance Environmental Conservation Support Program (Programa de Apoio à Conservação Ambiental Bolsa Verde), instituted by Law No 12,512 of 14 October 2011, and regulated by Decree No 7,572 of 28 September 2011, grants a benefit of BRL 300 every quarter to families in situations of extreme poverty that live in areas considered a priority for environmental conservation. Around 47% of the 16.2 million people living in extreme poverty are in rural areas, so the specific aim is to reconcile an increase in the income of this population to the preservation of ecosystems and the sustainable use of natural resources (Brazil, 2011). This new benefit, part of the Brazil Without Poverty Program (Programa Brasil Sem Miséria), is intended for those who develop activities for the sustainable use of natural resources in Extractive Reserves, National Forests, Federal Sustainable Development Reserves and the Environmentally Differentiated Settlements of the Agrarian Reform (Brazil, 2011, Pereira et al., 2016).

Regarding the local knowledge about the impacts of activities on fish resources and on the environment, it was possible to perceive that fishermen are aware that the fish stocks are decreasing and that affects the standard of living of those who depend solely on the activity to survive. However, most do not consider themselves responsible for this and do not consider the fishing gear used to pose any risk, except for those used by neighboring communities. It was also noticed that the community does not know how to react to the problem of fish reduction and, moreover, there are those who consider that the reduction of fish is a momentary phenomenon, making clear the need for lectures and informative courses about the consequences of unsustainable fishing. It was noted that there is already some empirical knowledge about the need to allow the reproduction and growth of the animals, since the community indicates the closure as a solution for the reduction of fishes and crustaceans.

Our environmental education activities included giving talks, films for children and delivering educational booklets, and they proved to be good tools for raising awareness in the community, since besides being informative, they led the residents to reflect on their present attitudes and the implications for the future. The booklet, produced in the form of comic strips and in simple language, also covered the child audience, who are the future fishermen of the region. Van Bressem et al. (2006) pointed out that the use of educational booklets is an extremely valuable tool in education, as biological information is presented in the form of a story that is easy to understand and remember. In addition, they can be read at any time and lent to other people. The cinema and the production of images gain strength in the contemporary world, appearing as a powerful tool of socialization of information and being able to function as special sources of education and knowledge construction (Oliveira, 2006, Fischer, 2009). According to Otto and Pensini (2017), in childhood the motivation to be ecologically friendly is formed and probably the effect lasts a lifetime (Evans et al., 2007).

Finally, the scenario 20 years from now as described by the residents themselves, shows a more critical situation than the current one, with scarcer resources and the search for new forms of livelihood. In this way, we can see a clear need for intervention by both the authorities and residents, as well as educational activities, and activities to raise awareness promoted by educational institutions and by governmental and non-governmental agencies.


The team wishes to thank the Maranhão Foundation for Scientific Research and Development (FAPEMA) for funding the project (Public Notice AEXT 1714). The team also wishes to thank the Committee of the Cururupu Extractive Reserve for their permission to carry out the project, and the fishermen for their involvement and collaboration. Our thanks also go to the State University of Maranhão for providing logistical support and transportation and Jefferson Horley for the English revision.
