Abstract

The aim of this study was to analyze temporal variation of fish eggs and larvae of the main exploited species in Miranda river, Pantanal wetland (Piaractus mesopotamicus, Prochilodus lineatus, Salminus maxillosus, Leporinus macrocephalus, and Pseudoplatystoma spp., which were collected from October to March, biweekly, from 1996 to 1999. The river was divided into superior, medium and inferior sections, of 15 collection sites. Conical-cylindrical plankton net with a fluxometer and samples fixed in formol 4% were utilized. Morphological and meristic characteristics, notochord flexion degree and caudal fin elements were utilized for identification. A total of 5,979 larvae and 1,075 eggs were collected in the first period; 108,912 larvae and 1,836 eggs in the second; 13,465 larvae and 1,855 eggs in the third. Results showed that ANOVA, between the years and the river stretches, was significant (F = 6.5, p >0.05) in the medium section, which indicates that the reproduction occurs from medium to superior section from November to January
