Abstract: The goliath grouper Epinephelus itajara is a large sized (> 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 knowled… Show more

“…(see Bullock andSmith 1991, Koenig and). In Brazil, Gerhardinger et al (2006) also confirmed this pattern through surveys of fishermen ecological knowledge, which indicate that most commonly food items of the goliath grouper are lobsters, spadefish Chaetodipterus faber, octopuses, and catfish (Family Ariidae). Altogether, information on the diet of E. itajara available Symbols represent the factor habitat: mangrove (▼) and coral reefs (•); Vectors superimposed on the nMDS diagram were created by using the Spearman's correlation on the proportionate contributions of the food categories that most influenced the ordination to date indicates predominance of large sized and slow moving preys (Bullock and Smith 1991).…”

“…Through the observation of our sketch maps, we conclude that E. itajara is frequently found inhabiting rocky bottoms (rocky shores and outcrops) and shipwrecks. However, the species may also occur inside the bay, associated with structures formed by the accumulation of drift wood, brought from the upper estuary during strong storms (Gerhardinger, 2006b). Our informants were unable to differentiate locations where larger (deeper than 40-60 kg) and smaller (less than 40-60 kg) individuals are found.…”

“…Longline fishing has been practiced in the area for at least three generations, and it uses a fishing gear devised to target mainly goliath groupers and other large finfish. Spearfishing, however, is a much newer practice (few decades) (Gerhardinger et al, 2006b). Each informant was interviewed individually with previous consent.…”

“…Individuals of Lutjanus jocu observed in the photos were possibly captured in reproductive aggregations, since peaks of capture can be interpreted as indirect signs of this type of aggregation (Colin et al 2003). Considering the vast coast of Brazil, very few studies related reef fisheries to fish forming spawning aggregations , Gerhardinger et al 2007. Knowledge on where reef fish aggregations occur is very important for the conservation of the target species, even more for those fishes commercially exploited.…”
