“…The greatest reproductive intensities were registered from January to May for X. kroyeri and from September to November for F. subtilis, which is in agreement with the results from previous studies on these species in other regions of Brazil (SANTOS and IVO, 2000;SANTOS et al, 2001;CASTRO et al, 2005, SANTOS andFREITAS, 2006;ALMEIDA et al, 2012;HECKLER et al, 2013;CASTILHO et al, 2015). For L. schmitti, due the low number of reproductive females (≤ 11) and developed males (≤ 12) during all studied months, our results should be considered with caution.…”

RESUMOEste estudo avaliou se a reprodução e o recrutamento temporal e espacial das principais espécies de camarões marinhos explotados no Estado de Sergipe (Xiphopenaeus kroyeri, Farfantepenaeus subtilis e Litopenaeus schmitti) estão sendo protegidos, em comparação com normativa MMA nº 14, de 14 de outubro de 2004. As coletas foram realizadas de setembro/2013 a agosto/2014 na plataforma continental de Sergipe, em nove transectos, distribuídos nas profundidades de 5, 15 e 30m, utilizando um barco camaroeiro equipado com rede de arrasto de portas. Após as coletas os indivíduos foram identificados ao nível específico, subamostrados, sexados, mensurados quanto ao comprimento da carapaça e classificados quanto à morfologia gonadal. O recrutamento e a reprodução das três espécies ocorreram continuamente ao longo do ano, apresentando picos de intensidade. Indivíduos reprodutivos e juvenis foram mais abundantes nos 30m para F. subtilis, enquanto para X. kroyeri e L. schmitti foram mais abundantes nos 5m e 15m. A atual instrução normativa protege parcialmente as categorias reprodutivas e juvenis dessas espécies, principalmente F. subtilis. Portanto, sugere-se a adequação dos períodos de defeso para as épocas de reprodução e recrutamento de F. subtilis, uma vez que a área estipulada pelo IBAMA já protege as demais espécies ao longo do ano.Palavras chave: Xiphopenaeus; Farfantepenaeus; Litopenaeus; recrutamento; período reprodutivo; pesca. ABSTRACTThis study evaluated if the temporal and spatial reproduction and recruitment of the main species of marine shrimps exploited in the state of Sergipe (Xiphopenaeus kroyeri, Farfantepenaeus subtilis, and Litopenaeus schmitti) are being protected, in relation to the closed season based on the normative instruction MMA n° 14, of October 14 th 2004. The samples were collected monthly from September 2013 to August 2014 at the continental shelf of Sergipe, in nine transects, distributed in the depths of 5, 15, and 30 m using a shrimping boat equipped with double ring nets. After sampling, we identified shrimps to the species level; subsampled, sexed them, measured carapace length, and observed the gonads. Recruitment and reproduction in the three species occur continuously, albeit with intensity peaks. Regarding space, reproductive individuals and recruits were more abundant at 30 m in the case of F. subtilis, while for X. kroyeri and L. schmitti, higher abundances were found at 5 and 15 m. The current normative instruction partially protects the reproductive and juveniles categories of these species, mainly F. subtilis. Thus, we suggest closed seasons at breeding and recruitment seasons of F. subtilis, since the area set by IBAMA already protects other species throughout the year.

“…When spermatophores were not visible through macroscopic observation in an adult male, the individual was classified as lacking spermatophores (LS). If spermatophores were visible and occupied a portion of or all terminal ampoules, males were classified as spermatophore-bearing males (MA) (Castilho et al, 2012(Castilho et al, , 2015. Males with gonads in the LS and MA stages were defined as adults, while those with gonads in the MA stage were considered reproductive males, and those with gonads in the IM stage were defined as recruits.…”

“…Such studies are important for the development of management plans for these shrimps, where the biological parameters obtained from the Von Bertalanffy (1938) growth model, associating individual size and age, provide estimates of mortality rates and longevity. The formulation of a mathematical model for age determination in crustaceans is of great importance, as crustaceans do not exhibit permanent bony structures; instead, the crustacean exoskeleton is periodically replaced in a process termed ecdysis, making evaluations based on periodic markings on their body surface impossible (Hartnoll, 2001;Keunecke et al, 2011;Castilho et al, 2015).…”

“…Studies of X. kroyeri along the São Paulo coast have focused on aspects of their population biology (Nakagaki and Negreiros-Fransozo, 1998;Castro et al, 2005), reproductive biology and recruitment (Almeida et al, 2012;Heckler et al, 2013a;Castilho et al, 2015), population dynamics (Heckler et al, 2013b), and abundance and distribution (Costa et al, 2007;Simões et al, 2010;Heckler et al, 2014a;2014b). However, most of these studies did not address variation in biomass and individual size through monthly samples.…”

Temporal variations in biomass and size of seabob shrimp Xiphopenaeus kroyeri (Heller, 1862) (Decapoda: Penaeoidea) on the southern coast of São Paulo state, Brazil

Xiphopenaeus kroyeri (Heller, 1862) is the third most common species caught by fi shing boats in the state of São Paulo, Brazil and production of this shrimp in the Cananéia region located on the southern coast of this state ranks second in the nation. Th e aim of this study was to investigate the temporal variation of the total biomass and size of X. kroyeri and analyze this variation against environmental factors in order to suggest some information about the best periods to fi sh this species. Samples were caught monthly from four sampling stations in Cananéia between July 2012 and June 2014 using a fi shing boat equipped with ott er-trawl nets. Temperature and salinity were monitored using a multiparameter probe, and sediment samples were also taken using a Van Veen-type gripper for particle size analysis. Th e shrimp were weighed, quantifi ed, and carapace length was measured (mm). In general, the highest total biomass values were recorded when the fi shery was closed in the southeast and south regions, and the highest catch of smaller individuals was also observed during this period. In contrast, in November 2013 the fi shing is permitt ed and high biomass composed of large individuals was observed. Th e monthly biomass showed a positive relationship with sediment texture, because this species prefers very fi ne sediments to burrow as a defense against predators. keY wordsAbundance, closed season, fi shery, Penaeidae, weight.
