Moon, tidal and diel influences on catch composition of fishes in the surf zone of Pontal do Sul beach, Paran\ue1

Abstract

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
