LOPES, Priscila Fabiana Macedo and BEGOSSI, Alpina. Temporal changes in caiçara artisanal fishing and alternatives for management: a case study on the southeastern Brazilian coast. Biota Neotrop. [online]. 2008, vol.8, n.2. ISSN 1676-0611. http://dx.doi.org/10.1590/S1676-06032008000200005.
This paper describes a case study of the changes in fishing that occurred in a Brazilian coastal community after a 10 year interval (1992-2002). There was a decrease in the mean amount of fish caught daily (from 14 kg to 11.32 kg) and annually (from 4.2 t to 3.4 t) and in the richness of species caught (from 21 to 17 species); there was also a low similarity in the species composition of the fish landings (Morisita-Horn index Ch = 0.24). These changes suggested a decline in the locally exploited fish populations, which probably caused the discontinuation of commercial artisanal fishing. However, the diversity of fish caught by hook and line and purse-seine fishing was higher in the second period, whereas there was no significant difference in the diversity of fish caught using gillnets. Despite these changes, the CPUE showed no significant alteration and non-intensive fishing is still practiced by a few (6-35) people in the community. Co-management alternatives (fishing regulations, oysterfarms, ecotourism, etc.) are suggested and may be applicable to other coastal communities after appropriate adaptation for each location.
