Abstract Ovigerous females of the freshwater shrimp Macrobrachium borellii were exposed to three sublethal concentrations (0.01, 0.1, and 1 mg/L) diclofenac sodium salt, for 74 d, in order measure several variables related both reproductive success oxidative stress. Although no differences (p > 0.05) noted either egg incubation time or postlarvae survival, number hatched (actual fecundity) decreased some extent, together with a low percentage abnormal larvae. At end assay, ovarian...
Abstract Prochilodus lineatus (Val.) is one of the main target species South American freshwater fisheries. The following null hypotheses regarding juvenile recruitment P. were tested: (a) not determined by variations in larval abundance and (b) discharge. For this purpose, larvae channel drift monthly captures juveniles a floodplain lake River Paraná examined weekly between 2009 2016. Mean annual abundances densities CPUE correlated with set hydrometric variables. A positive correlation was...
The aim of this work was to compare age determinations and precision using two deposition structures trahira Hoplias malabaricus (Bloch, 1794): the scales, which are most frequently used, otoliths (lapilli). length-age relationships were obtained with both compared results from previous studies. 163 sets (lapilli) scales 17–46 cm standard length (SL) Cayastá (Santa Fe) Islas Lechiguanas (Entre Ríos), Paraná River, Argentina. Three independent readings each structure conducted. An bias plot...
In South America, the order Atheriniformes includes monophyletic genus Odontesthes with 20 species that inhabit freshwater, estuarine and coastal environments. Pejerrey argentinensis is widely distributed in areas of Atlantic Ocean known to foray into estuaries river systems, particularly conditions elevated salinity. However, our knowledge, a landlocked self-sustaining population has never been recorded. this study, we examined pejerrey Salada de Pedro Luro Lake (south-east Buenos Aires...
Length–weight relationships (LWR) were estimated for 12 species, representing three orders and eight families of fishes from the Paraná Uruguay rivers in Argentina: Acestrorhynchus pantaneiro, Cynopotamus argenteus, Pachyurus bonariensis, Pterodoras granulosus, Hypostomus commersoni, Pseudoplatystoma corruscans, Pimelodus maculatus, Parapimelodus valenciennis, Salminus brasiliensis, Prochilodus lineatus, Hoplias malabaricus Leporinus obtusidens. For last four length at first spawning (Lm)...
We studied the reproductive strategy, sexual system and growth of dientudo paraguayo Acestrorhynchus pantaneiro. After 2 years monitoring in shallow areas a floodplain lake from lower Paraná basin (Argentina), it was evidenced that water temperature modulated gonadal maturation, but river level synchronising stimulus triggered spawning. This species exhibited single annual breeding period October to January, with most spawning activity November. According von Bertalanffy curve, fish would...

Early life stages of migratory fish in rivers rely on physical transport mechanisms to carry them from spawning sites distant nursery areas where they find food and refuge conditions. Starvation after a prolonged downriver drift could severely affect the colonisation predator evasion capabilities larvae. In this study we investigated differences external morphology, nutritional condition swimming abilities fed unfed Prochilodus lineatus early larvae under experimental After yolk reabsorption...
