Larval fish in the surf zone of Pontal do Sul beach, Pontal do Paraná, Paraná, Brazil Zoologia
Godefroid,Rodrigo Santiago; Hofstaetter,Marion; Spach,Henry Louis.
A total of 6,575 larvae in the preflexion, flexion and post-flexion stages of 15 families, 26 genera and 29 species were captured in the surf zone of Pontal do Sul beach, Paraná, Brazil. Samples of the families Gerreidae and Scianidae predominated and larvae of Eucinostomus argenteus (Baird&Girard, 1854), Micropogonias furnieri (Desmarest, 1823), Eucinostomus gula (Cuvier, 1830), Menticirrhus ameri-canus (Linnaeus, 1758) and Anchoa tricolor (Agassiz, 1829) were the most dominant species. Greater abundance of larvae was observed during the summer, followed by winter and in a less extent during spring and autumn. The number of species was greater in the summer, and there were no significant differences in the rest of the seasons.

Moon, tidal and diel influences on catch composition of fishes in the surf zone of Pontal do Sul beach, Paraná Zoologia
Godefroid,Rodrigo Santiago; Hofstaetter,Marion; Spach,Henry L..
Fishes were sampled by beach seine during the day and night at the high and low sygygy tides, on a sandy beach at the southeast coast of Brazil. The quantitative results appear to indicate a larger concentration of fish in the surf zone of this beach, in low tides at the start and end of the day. Only eight from the 17 most abundant taxa, appeared to have been influenced singly or in combination by the factors of the moon, day, night and tide.

Occurrence of Larvae and Juveniles of Eucinostomus argenteus, Eucinostomus gula, Menticirrhus americanus, Menticirrhus littoralis, Umbrina coroides and Micropogonias furnieri at Pontal do Sul beach, Paraná BABT
Godefroid,Rodrigo Santiago; Santos,César; Hofstaetter,Marion; Spach,Henry Louis.
Despite its importance, most ichthyoplankton studies in the South-Southeastern coast of Brazil, have been accomplished on the continental shelf. Regarding the beach environment, recognized as a nursery, little is known about the ichthyoplankton. We analyzed 288 samples collected with a 18 by 2 m seine net, 1 mm mesh and a conical plankton net, with a mesh of 300 mum and a 60 cm mouth. Eucinostomus argenteus comprised 78 % of the larvae and juveniles caught in the samples. The occurrence of gerreids was strongly concentrated in the summer, while the Menticirrhus littoralis, Menticirrhus americanus and Umbrina coroides were present during all seasons. M.littoralis was most abundant during spring, while M. americanus and U. coroides dominated during winter....
