The goliath grouper Epinephelus itajara is a large sized (&gt; 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological...

ABSTRACT The Atlantic goliath grouper, Epinephelus itajara , is a critically endangered species, threatened by illegal fishing and the destruction of its habitats. A number of other closely related grouper species found in the western Atlantic are also fished intensively. While some countries apply rigorous legislation, illegal harvesting followed by the falsification of fish products, which impedes the correct identification of the species, is a common practice, allowing the catch to be marketed as a different grouper species. In this case, molecular techniques represent an important tool for the monitoring and regulation of fishery practices, and are essential for the forensic identification of a number of different species. In the present study,...

Abundância relativa e distribuição espaço-temporal de Micropogonias furnieri (Desmarest) e Cynoscion leiarchus (Cuvier) (Perciformes, Sciaenidae) no manguezal do Itacorubi, Santa Catarina, Brasil

Attempting to contribute with the knowledge about the bioecological aspects concerning the youth forms of M. furnieri (Desmarest, 1823) and C. leiarchus (Cuvier, 1830) from Itacorubi mangrove, 15 samplings were taken from January 1988 to March 1989. Using casting and entangle nets, a total of 308 individuais from these species were captured. Their abundanee were: M. furnieri N = 197 (64,0%); C. leiarchus N = 111 (36,0%). The relative frequency and range of total weights and lengths were studied. Concerning spatial distribution of the species, it was observed that M. furnieri occurred in all areas and C. leiarchus was not captured only in "D" area (Sertão River). During the anual cycle the two species occurred jointly. The results emphasize other authors...

Reproductive biology of the dusky grouper Epinephelus marginatus (Lowe, 1834)
Provedor de dados: 52
Autores: Andrade,Áthila Bertoncini; Machado,Leonardo Francisco; Hostim-Silva,Maurício; Barreiros,João Pedro.
Investigations were carried out about the reproductive biology of the dusky grouper, Epinephelus marginatus (Lowe, 1834) a serranid protogynous hermaphrodite fish inhabitant of rocky bottoms from shallow waters up to 200 m depth. Samples were caught in the islands that form Arvoredo Biological Marine Reserve (SC - Brazil) and the coastal islands near Florianópolis region from March 1998 to May 2000. Data from samples of juvenile groupers on intertidal pools were used to link their occurrence in the pools to the post-spawning season. To describe the histological changes on gonads along the reproductive cycle and to establish maturation scales, 109 groupers were histologically tested for sex determination. First maturation size was determined for females...

Diversity and seasonal changes in the ichthyofauna of rocky tidal pools from Praia Vermelha and São Roque, Santa Catarina
Provedor de dados: 52
Autores: Barreiros,João P.; Bertoncini,Áthila; Machado,Leonardo; Hostim-Silva,Maurício; Santos,Ricardo Serrão.
A survey of the tidal pool fish community was carried out between April 1998 and May 1999, at the beaches of Praia Vermelha (PV) and São Roque (SR), Santa Catarina, Brazil. The pool of PV was bigger and closer to the subtidal. Specimens were collected monthly at low tide, using quinaldine. In PV we collected 1287 fish belonging to 19 species and in SR 553 fish were caught corresponding to 11 species. In both pools, dominant species were Bathygobius soporator (Gobiidae), Abudefduf saxatilis (Pomacentridae), Parablennius pilicornis (Blenniidae), Gobiesox barbatulus (Gobiesocidae), Labrisomus nuchipinnis (Labrisomidae) and Epinephelus marginatus (Serranidae). Summer months had higher abundance and diversity values, and correspond to a recruitment season for...
