Goniopsis cruentata is a common semi-terrestrial crab in Brazilian mangroves and an important fishery resource for traditional communities in the northeastern Brazilian coast. Aiming to contribute to the knowledge about the species, this study evaluated the carapace width and weight growth curves, the relative growth of weight versus carapace width, and the temporal variation of gonadosomatic and hepatosomatic indices for the species. A total of 524 crabs were collected in a mangrove area of Ubatuba municipality, state of São Paulo. The growth-curves parameters and longevity (tmax) were estimated for males (CW∞=50.6 mm, WE=56.4 g, k=2.24, t0=0.003631502 year-1, tmax=1.3 years) and females (CW∞=50.7 mm, WE∞=58.8 g, k=2.50, t0=0.003247209 year-1, tmax=1.2 years). The age at onset of sexual maturity was 0.23 years for both genders. The weight-growth model was isometric for the immature developmental stages and allometric negative for adults. The species exhibited a continuous reproduction, with breeding peaks in spring and summer months. The weight dynamics of gonads and hepatopancreas were not clearly related. The growth and reproductive patterns indicated that Goniopsis cruentata has a life-history that prioritizes reproduction instead of survival. The species exhibited some of the highest growth rates and lowest longevity estimates reported for brachyuran species in Brazil.

Goniopsis cruentata é um caranguejo semi-terrestre comum em manguezais brasileiros e um importante recurso pesqueiro para comunidades tradicionais no nordeste do Brasil. Com o objetivo de contribuir com o conhecimento sobre a espécie, o presente estudo avaliou as curvas de crescimento em largura de carapaça e em peso, o crescimento relativo do peso pela largura da carapaça e a variação temporal dos índices gonadossomático e hepatossomático para a espécie. Um total de 524 caranguejos foram coletados em área de manguezal no município de Ubatuba, estado de São Paulo. Os parâmetros das curvas de crescimento e a longevidade (tmax) foram estimados para machos (CW∞=50,6 mm, WE∞=56,4 g, k=2,24, t0=0,003631502 ano-1, tmax=1,3 anos) e fêmeas (CW∞=50,7 mm, WE∞=58,8 g, k=2,50, t0=0,003247209 ano-1, tmax=1,2 anos). A idade no início da maturidade sexual foi de 0,23 anos para ambos os sexos. O modelo de crescimento em peso foi isométrico para indivíduos em estágios de desenvolvimento imaturos e alométrico negativo para adultos. A espécie exibiu reprodução contínua com picos reprodutivos nos meses de primavera e verão. A dinâmica de peso das gônadas e hepatopâncreas não estiveram claramente relacionadas. Os padrões de crescimento e reprodução indicaram que Goniopsis cruentata possui uma história de vida que prioriza a reprodução em detrimento da sobrevivência. A espécie exibiu algumas das maiores taxas de cresci mento e menores estimativas de longevidade relatados para espécies de braquiúros no Brasil.

The crab Goniopsis cruentata (Latreille, 1803) is a common semi-terrestrial species in Brazilian mangroves. Its geographical range includes the western Atlantic Ocean from Bermuda to Brazil, and the eastern Atlantic Ocean from Senegal to Angola (Melo 1996). The species is an important fishery resource for traditional communities in the northeastern Brazilian coast (Santos and Botelho 2002, Moura and Coelho 2004). There are no reports of economic exploitation of G. cruentata in the southeastern Brazilian coast. However, the exploitation of the species might become attractive in the future with the increasing decline in populations of crabs of economic importance in these coast (see Dias Neto 2011), as observed in the northeastern coast of Brazil (see Botelho et al. 2004). Beyond its economic value, G. cruentata may also play an important role in the functioning of mangrove ecosystems, by acting as an engineer species (Lima-Gomes et al. 2011), probably affecting soil biogeochemistry, rates of decomposition, and nutrient cycling (see Werry and Lee 2005, Kristensen 2008).

Some studies evaluated biological aspects of G. cruentata in Brazil: Silva and Oshiro (2002a) investigated the species growth in captivity; Lira et al. (2012) evaluated the weight versus carapace width relationship and the condition factor; Cobo and Fransozo (1998, 2005) and Moura and Coelho (2004) studied its physiological sexual maturity; Cobo and Fransozo (2000, 2003), Silva and Oshiro (2002b), and Moura and Coelho (2003) investigated reproductive aspects such as fecundity and breeding period; Garcia and Silva (2006) described the species testis and vas deferens morphology, and spermatophore formation; Garcia and Silva (2009) described the sperm cell development; Souza and Silva (2009) described the morphology of the female reproductive system and the development of the germ cells; Fransozo et al. (1998) described the species first zoeal stage; Moura et al. (2000), Santos and Botelho (2002), and Botelho et al. (2004) provided information on population structure; Lima-Gomes et al. (2011) investigated its feeding behaviour; and Maciel and Alves (2009) analyzed the knowledge and practices of traditional gatherers on the species.

Because of the species ecological and economic importance, the present study aimed to contribute to the knowledge about G. cruentata, providing information regarding the growth and reproduction, through the study of carapace width and weight growth curves, relative growth of weight versus carapace width, and gonadosomatic and hepatosomatic indices. The growth curve study provides information on growth rate, the age at onset of sexual maturity, the maximum body size attained, and the maximum longevity. Studies that described growth curves for brachyuran species in Brazil include Branco and Masunari (1992) for Callinectes danae; Branco and Lunardon-Branco (1993) for Callinectes ornatus; Ivo et al. (1999), Vasconcelos et al. (1999), and Pinheiro et al. (2005) for Ucides cordatus; Branco et al. (2002) for Portunus spinimanus; Silva-Castiglioni et al. (2004) for Uca rapax; Pimenta et al. (2005) for Armases rubripes; Pinheiro and Taddei (2005a), Taddei and Herrera (2010), and Davanso et al. (2013) for Dilocarcinus pagei; Pinheiro and Hattori (2006) for Arenaeus cribrarius; Barcelos et al. (2007) for Chasmagnathus granulatus; Keunecke et al. (2007) for Hepatus pudibundus; and Ferreira and D'Incao (2008) for Callinectes sapidus. The weight dynamics of gonads and hepatopancreas show metabolic processes underlying the reproductive cycle (see e.g. López-Greco and Rodríguez 1999, Rosa and Nunes 2002, 2003), and the relationship between the weight and the carapace-width enables the conversion between these variables and provides the weight growth rate. The information provided in the present study is useful to studies of aquaculture viability and studies establishing management guidelines for exploitation of natural populations (see e.g.Mello 1973, Santos 1978, Valenti et al. 1987, Dias Neto 2011), so far not available for the species.



Monthly collections from April 2007 through March 2008 were carried out in a mangrove area, (23°29'24"S, 45°10'12"W) located inland of Praia Dura in Ubatuba municipality, state of São Paulo, southeastern Brazil (Fig. 1). The crabs were hand-caught at low tide by 4 people for 1h/month without the use of traps or baits, and kept frozen until laboratory analysis. For each crab, the following measurements were recorded: (1) the gender and the developmental stage: young male (YM), adult male (AM), young female (YF), prepubertal female (PPF), and adult female (AF), based on the external morphology of the abdomen as proposed by Cobo and Fransozo (1998) and the adherence of the abdomen to the sternum criteria as proposed by Haefner (1990); (2) the carapace width (CW), measured with a vernier caliper (0.1 mm); (3) the total weight (WE), measured on a digital balance (0.1 g); and (4) the gonad (GW) and the hepatopancreas (HW) weights for both males and females, measured on a semi-analytical balance (0.001 g). The monthly air-temperature recorded for the period were obtained from the Instituto Agronômico de Campinas (IAC) in Campinas municipality for Ubatuba station (available at

Figure 1. - Location of the Praia Dura in Ubatuba municipality, São Paulo, Brazil. 


The carapace width and the weight-growth curves were described for each gender according to the Bertalanffy model (1938): "CW = CW∞ [1−e−k(t−to)]" and "WE = WE∞[1−e−k(t−to)]b", in which "CW∞" is the asymptotic carapace width, "WE∞" is the asymptotic weight, "e" is the basis of the Neperian logarithm, "k" is a constant related to the species growth rate, "t" is the age of the body size considered, "to" is the age related to the body size at birth (CWo), and "b" is the allometric growth constant of the weight-carapace-width relationship. The main age groups for the period and the growth-curve parameters "CW∞" and "k" were estimated by the size-class distribution method (Fonteles-Filho 1987). The CW records were grouped monthly into 5-mm size classes. The modes were identified by the Bhattacharya's method (1967) and confirmed by the NORMSEP routine (Pauly 1987) in the Elephan program of the FiSAT II (version 1.2.0) software package (Gayanilo et al. 2005). The "to" value was estimated by substituting the zoea I mean carapace width (CWo) of Goniopsis cruentata, equal to 0.41 mm according to Fransozo et al. (1998), in the carapace-width growth equation. The "WE∞" was obtained by substituting the "CW∞" in the weight-carapace-width equation. Longevity was calculated according to Taylor (1958) through the equation "tmax = 3/k + to". The age at the onset of sexual maturity was estimated for each gender by substituting the size at physiological maturity proposed by Cobo and Fransozo (2005) for the same population of the present study, estimated as the size at which 50% of individuals attained gonadal maturity (males = 21.0 mm CW, females = 22.6 mm CW), in the CW growth curves described.

For the relative growth analysis of weight versus carapace width, the WE and CW data were grouped according to gender and developmental stages. The data were subjected to a regression analysis with adjustment by the power function "WE = a CWb", in which "a" is the intercept and "b" is the allometric constant related to the weight-growth model: isometric (b = 3), allometric negative (b < 3), or allometric positive (b > 3). The determination coefficient (r2) was used to evaluate the adjustment to the proposed model.

The gonadosomatic (GSI) and hepatosomatic (HSI) indices were estimated monthly for each sex through the equations "GSI = GW/WE x 100" and "HSI = HW/WE x 100" (Vazzoler 1981, 1996).

Except for the modal progression analysis of CW, data of individuals with regenerating appendages were excluded from the analysis due to their influence on the individuals' WE.


Normality was evaluated using the test of D'agostino (D'agostino 1970). Differences in the relative growth model between the genders and developmental stages were evaluated by comparing the angular (b) and linear (a) values using an ANCOVA (one-way) followed by the post hoc Tukey HSD test. The adjustment of "b" values to an isometric weight-growth model was evaluated using a t-test. The temporal variation of GSI and HSI for each gender was assessed by the test of Kruskal-Wallis followed by the post hoc Student-Newman-Keuls test. The relationship between variables was evaluated using the Spearman correlation analysis. Differences at the 0.05 level were considered as significant. All statistical analysis were performed according to Zar (2010).


A total of 524 crabs were obtained, being 26 young females, 68 prepubertal females, 196 adult females, 34 young males, and 200 adult males. Males exhibited mean body-sizes of 32.3 ± 7.5 mm CW and 19.6 ± 12.5 g, ranging from 10.2 to 50.2 mm CW and 0.6 to 61.7 g. For females, mean body-sizes were 32.3 ± 6.8 mm CW and 17.2 ± 8.8 g, ranging from 13.3 to 50.1 mm CW and 0.5 to 49.4 g.

The CW∞ values estimated by the modal progression analysis (Fig. 2) were 50.6 mm for males and 50.7 mm for females. The constant "k" was 2.24 for males and 2.50 for females; and the parameter "to" was 0.003631502 years (about 1.3 days) for males, and 0.003247209 years (about 1.2 days) for females. The carapace-width growth can be described by the equation CW = 50.6 [1−e −2.24(t+0.003631502)] for males, and by CW = 50.7 [1−e −2.50(t+0.003247209)] for females.

The W∞ values were 56.4 g for males and 58.8 g for females. The weight growth can be described by the equation WE = 56.4 [1−e−2.24(t+0.003631502)]2.72 for males, and WE = 58.8 [1−e−2.50 (t+0.003247209)]2.93 for females. The longevity (tmax) estimates were 1.3 years for males and 1.2 for females. The body-size estimates at the maximum age were 48.1 mm CW and 49.2 g for males and 48.2 mm CW and 50.7 g for females.

Physiological maturity occurred at 0.23 years for both males and females.

Differences in the relative growth model were found between the genders (F = 19.54, df = 1, 469, p < 0.0001) and developmental stages of males (F = 28.51, df = 1, 206, p < 0.0001) and females (F = 8.36, df = 2, 260, p = 0.0003; Tukey HSD, p < 0.0001). The weight-growth model was isometric for the immature developmental stages and allometric negative for adults (Table I).

The GSI analysis revealed a continuous gonadal activity during the study period (Fig. 3). The testicular activity did not vary significantly throughout the period (H = 16.11, df = 11, 167, p = 0.1371). In contrast, females showed higher ovarian activity from August through March (H = 60.30, df = 11, 165, p < 0.0001). The GSI of females was positively correlated to the mean air temperature (rs = 0.35, df = 175, p < 0.0001). The HSI of both males and females declined in June, remained low until January, and increased in February (Males: H = 69.24, df = 11, 196, p < 0.0001; Females: H = 72.93, df = 11, 251, p < 0.0001) (Fig. 3).The HSI of males was positively correlated to the GSI (rs = 0.25, df = 177, p = 0.0006). The HSI of females was not correlated to GSI (rs = 0.08, df = 261, p = 0.0804).

The number of individuals in each month ranged from 8 to 23, with a mean of 15. The mean air-temperature is indicated by the dashed line. 


Sample sizes proved to be adequate to describe the species growth curves as all modes exhibited statistically significant separation indexes. The low number of juveniles collected due to biased sampling (very small crabs are harder to collect) is a common feature in studies with brachyuran species (see, e.g. Moura et al. 2000, Pinheiro et al. 2005, Pinheiro and Hattori 2006, Keunecke et al. 2007). However, this deficiency was counteracted by the growth rate and longevity estimates performed using FiSAT II.

Goniopsis cruentata exhibited high growth rates and low longevity compared to other brachyuran species in Brazil (Table II). Only Armases rubripes (Pimenta et al. 2005), Chasmagnathus granulatus (Barcelos et al. 2007), and Hepatus pudibundus (Keunecke et al. 2007) were reported to exhibit growth rates as high as G. cruentata. None of the species listed in Table II were reported to exhibit longevity estimates as low as G. cruentata. Although most longevity estimates reported for brachyuran species in Brazil fall between 2 and 4 years, some authors had already reported probable annual cycles for brachyuran species indicated by modal progressions ending in approximately one year, like Taddei and Herrera (2010) and Davanso et al. (2013) reported for Dilocarcinus pagei. The species G. cruentata also exhibited continuous reproduction confirmed by GSI analysis, successive broods as indicated by the short length cohorts observed during the entire study period, and early sexual maturity at 0.23 years (2.8 months) compared to other brachyuran species in Brazil, which range from 5 months for Arenaeus cribarious (Pinheiro and Hattori 2006) to 3 years for Ucides cordatus (Pinheiro et al. 2005). Earlier, Cobo and Fransozo (2000) found a considerably high mean fecundity for this same population (about 57,000 eggs per brood). All these traits suggest that G. cruentata has a life-history that prioritizes reproduction instead of survival, wherein a fast growth provides selective advantages for both genders. Fast growing individuals attain sexual maturity at larger body sizes. For G. cruentata, larger females were found to produce a greater number of eggs per brood (Cobo and Fransozo 2000) while larger males probably defeat the smaller ones in competition for receptive females and get accepted more frequently by females, as observed for other brachyuran species (see Jaroensutasinee and Jaroensutasinee 2003, Brockerhoff and McLay 2005).

Females of G. cruentata exhibited a higher growth rate and were larger than same-aged males. This pattern is not commonly reported for Brachuyra, only Pinheiro and Taddei (2005a) and Taddei and Herrera (2010) found the same for the freshwater crab Dilocarcinus pagei. Females are more frequently found to exhibit similar or lower growth rates (see Table II) and smaller body sizes than same-aged males as reported for Callinectes ornatus (Branco and Lunardon-Branco 1993), Portunus spinimanus (Branco et al. 2002), Arenaeus cribrarius (Pinheiro and Hattori 2006), and Chasmagnathus granulatus (Barcelos et al. 2007). Sexual dimorphism in size in which males are larger than females is considered an important reproductive strategy in Brachyura, specially for species whose females' sexual receptivity is associated with molting events. During and after copulation, males hold females providing protection against predators and other males until female's exoskeleton becomes calcified, ensuring paternity and reducing sperm competition. The larger body size of males compared to females allows an easier pair formation in such cases (Pinheiro and Fransozo 1999, Brockerhoff and McLay 2005, Pinheiro and Hattori 2006). For G. cruentata, females become sexually receptive during intermolt periods when the gonopore opercula become mobile (Hartnoll 1968) and males do not provide post-copulatory guarding (Schöne and Schöne 1963 apud Brockerhoff and McLay 2005, Schöne 1968). It seems that there are no strong selective pressures for G. cruentata males grow faster than females. In this context, fast growing females would have a selective advantage because they attain sexual maturity at larger CW sizes with a greater cephalothoracic space for gonad development and egg production, therefore improving reproductive effort (Pinheiro and Taddei 2005a, Taddei and Herrera 2010).

Silva and Oshiro (2002a) investigated the molt increment and intermolt period of G. cruentata in captivity collected in a mangrove area of Mangaratiba, state of Rio de Janeiro. These authors reported a continuous growth through successive molts and a similar mean number of molts (about 3) and molt increment (6.1%) for males and females over the 1.25 years of study period, suggesting that both genders exhibited similar growth rates, in contrast to the findings of the present study. At the beginning of that study, individuals had a mean size of about 36 mm CW and about 7% of them survived for an additional 1.25 years, which is the entire lifespan estimated for the species in the present study. According to the longevity estimates and CW growth curves described here, individuals exhibiting 36 mm CW would be about 0.5 years old and would live for an additional 0.7 to 0.8 years. As individuals attained similar CW sizes in both studies, the lower longevity exhibited by G. cruentata in the present study also implies in a higher growth rate compared to the population studied by Silva and Oshiro (2002a). Other authors also reported differences in absolute growth patterns for brachyuran species from different locations, even from close latitudes, which was mainly attributed to differences between habitats such as in primary productivity or sheltering (e.g. Silva-Castiglioni et al. 2004, Pinheiro et al. 2005, Ferreira and D'Incao 2008).

The relative growth study revealed that immature individuals of G. cruentata grew in carapace width and weight at the same proportion while adult individuals grew proportionally more in carapace width than in weight. Other authors reported changes in the weight-growth model through ontogeny for brachyuran species, including Mantelatto and Fransozo (1992) for Hepatus pudibundus, Pinheiro and Fransozo (1993) for Arenaeus cribarius, and Peiró et al. (2011) for Austinixa aidae. Mantelatto and Fransozo (1992) suggested that such changes occur as a result of hormonal processes associated with sexual maturity. As mentioned earlier, G. cruentata females exhibit a positive correlation between the carapace width size and the number of eggs produced (Cobo and Fransozo 2000), probably because larger females have a greater internal volume of the cephalothorax cavity available for gonad development (Hines 1982). Thus, the greater growth in carapace width after sexual maturity is achieved, may provide a greater reproductive effort for females. For G. cruentata males, the greater growth in carapace width with sexual maturity, may provide advantages in fights for receptive females. The allometric constants exhibited by adult males and females, which are within the lower range of allometric constants reported for brachyuran species in Brazil, ranging from 2.39 for Dilocarcinus pagei (Pinheiro and Taddei 2005b) to 5.00 for Austinixa aidae (Peiró et al. 2011). Araújo et al. (2012), suggested that the negative allometry exhibited by semi-terrestrial brachyuran species may be related to the branchial chambers development. Given the positive correlation between the carapace width size and the branchial chambers volume found in brachyuran species (Santos et al. 1985), a greater growth in carapace width may provide a higher surface area for branchiostegal lung development in the branchial chambers of G. cruentata.

The results of GSI analysis are in agreement with previous reports that G. cruentata has a continuous reproduction with breeding peaks in the warmest months of the year (e.g. Cobo and Fransozo 1998, 2003). The breeding period of brachyuran species in tropical and subtropical areas frequently follows a continuous pattern, probably due to the greater constancy of favorable conditions over the year compared to temperate zones, wherein crabs generally breed seasonally (Sastry 1983, Morgan and Christy 1995, Ramirez Llodra 2002, Litulo 2005). Breeding peaks are also frequently found for crabs in tropical and subtropical areas (e.g.Pillay and Nair 1971, 1973, Branco et al. 1992, Flores and Negreiros-Fransozo 1998, Leme 2002, 2006, Litulo 2005), probably as a result of successive broods (Sastry 1983). Like the seasonal breeding in temperate regions, breeding peaks in tropical and subtropical areas may have selective advantages because a larger amount of offspring are released under favorable abiotic conditions.

The GSI were not clearly related to HSI in G. cruentata. The synthesis of vitellogenin in decapods, which is the precursor of the common yolk protein stored during later phases of oogenesis, was suggested to occur in the ovary, in the hepatopancreas, from where vitellogenin would be transported through the hemolymph to developing oocytes, or in both organs (Tsukimura 2001). Several studies have supported the mobilization of resources from hepatopancreas to developing gonads in decapod crustaceans (e.g. Kyomo 1988, Pillay and Nair 1973, Haefner and Spaargaren 1993, Spaargaren and Haefner 1994, López-Greco and Rodríguez 1999) while a lower number of studies have found the opposite (e.g.Castille and Lawrence 1989, Cavalli et al. 2001, Rosa and Nunes 2002, 2003). The lack of a significant relationship between GSI and HSI for females, suggests that vitellogenin synthesis in Goniopsis cruentata might mainly occur in the ovary and be more dependent on resources from digestion than on hepatopancreas reserves. However, resources can be mobilized from hepatopancreas to developing gonads at the same time that hepatopancreas resources are restored by feeding (see Tuck et al. 1997). In this case, the weight dynamics of these organs could not evidence the transference of resources. Further studies are necessary to reach a conclusion, mainly studies that evaluate the dynamics of lipids, proteins, and vitellogenin in the ovaries, hepatopancreas, and hemolymph of the species. More-conclusive studies are necessary to better understand the role of hepatopancreas weight dynamics for the species.

The growth and reproductive patterns observed in the present study enabled the authors to conclude that Goniopsis cruentata has a life-history that prioritizes reproduction instead of survival.
