Observações sobre o ciclo de vida da corvina, Micropogonias furnieri (Desmarest) (Teleostei, Sciaenidae), no litoral do Estado do Paraná, Brasil

Abstract

ABSTRACT. Remarks aboul lhe life cycle oflhe croaker, Micropogoniasfurnieri (Desmaresl) (Teleostei, Sciaenidae), in the Paraná coast, Brazil. A survey performed in lhe Guaraluba Bay (25°52'S; 48°39'W) and lhe adjacent marine area has provided additional dala about lhe habils ofthe croaker in lhe soulhern coast ofBrazil. A dynamic pattem of movements along the marine and esluarine waters was observed, but it does not indicate spawning activity in the study area. During autumn/winter, pre-adults and adults use the marine waters. In springlsummer, following gonadal maturation, the individuais !eave this area and probab!y move to deeper walers, where they spawn. Until lhe end ofsummer, the estualy is then occupied by juveni!es cOllling frolll the marine spawning area. In autumn/winter, these juveni!es and the new pre-adults move to the marine zone adjacent to the bay and begin gonada! matllration. It is suggested that the Guaratuba Bay and the adjacent Illarine area constilule an important site for growth and recrllitment 01' the early life stages of M. furnieri and initia! stages of reprodllctive activity.

A method for assessing fishers’ ecological knowledge as a practical tool for ecosystem-based fisheries management: Seeking consensus in Southeastern Brazil

“…These data allowed important outputs such as the construction of maps with EFHs and identification of the major seasons of spawning and recruitment of important species of commercial value, which seems to be still very unclear for local science. In this sense, a consistent compatibility was found between the data transmitted by key fishers and some previous scientific studies in other regions for the: (1) white-mouth croaker Micropogonias furnieri (Menezes and Figueiredo, 1980;Robert and Chaves, 2001;Costa and Araújo, 2003;Bernardes et al, 2005;Carneiro et al, 2005;Carneiro, 2007;Vazzoler, 1971;Vazzoler et al, 1989); (2) seabob-shrimp Xiphopenaeus kroyeri (Nakagaki and Negreiros-Fransozo, 1998;Fransozo et al, 2000;Castro et al, 2005;Freire, 2005); (3) inshore squid Loligo spp. (Perez et al, 2002(Perez et al, , 2005Martins and Perez, 2006;Rodrigues and Gasalla, 2008;Gasalla et al, 2010;Postuma and Gasalla, 2010); (4) white shrimp Litopenaeus schimitti (Chagas-Soares et al, 1995;Costa, 2002;Castilho et al, 2007;Costa et al, 2007;Gonç alves et al, 2009) and (5) blue runner Caranx crysos (Leak, 1981).…”

A review of estuarine fish research in South America: what has been achieved and what is the future for sustainability and conservation?

“…A group of eight marine estuarine‐opportunists [rake stardrum Stellifer rastrifer (Jordan 1889), roughneck grunt Pomadasys corvinaeformis (Steindachner 1868), ground croaker Bairdiella ronchus (Cuvier 1830), G. genidens , Caitipa mojarra Diapterus rhombeus (Cuvier 1829), smooth weakfish Cynoscion leiarchus (Cuvier 1830), bigtooth corvine Isopisthus parvipinnis (Cuvier 1830) and sand whiff Citharichthys arenaceus Evermann & Marsh 1900] consistently represented between 80–90% of numbers and 75% of biomass. The life cycles and ecology of the dominant species have all been comprehensively studied (Chaves, , ; Chaves & Vendel, ; Chaves & Correa, , ; Chaves et al ., ; Chaves & Bouchereau, ; Robert & Chaves, ) and the importance of Guaratuba and its mangroves as a nursery area established beyond question. The common pleuronectiforms of Guaratuba, C. arenaceus and bay whiff Citharichthys spilopterus Günther 1862 spawn in mangrove areas and complete their life cycle wholly within the estuarine area (Chaves & Vendel, ) and S. rastrifer and B. ronchus are also estuarine spawners.…”

Long-term variation in the ichthyofauna of Flamengo Cove, Ubatuba, São Paulo

“…In terms of the number of individuals, we noticed that nearly 71% of the total number of individuals was sampled in spring, although the biomasses of both seasons are nearly 50% of the total weight. This shows that there are more individuals relatively smaller in spring than in autumn, which may indicate a possible reproductive season for at least some of the species (e.g., Araújo & Santos, 1999;Bernardes & Dias, 2000;Robert & Chaves, 2001;Castello & Castello, 2003;Godefroid et al, 2004;Lima & Castello, 2007;Bruno & Muelbert, 2009). As for the biomass, approximately 71% of the total weight was sampled in 1990 although the number of individuals did not differ much between the two years.…”
