Summary Major difficulties in studies monitoring or evaluating general environmental conditions are the intraspecific differences in population descriptors, such as the growth and reproductive period among different localities. The identification of feasible candidates for sentinel species requires basic information on these population parameters ...

Determination of the growth parameters of a species is an indispensable requirement for understanding its biology and consequently the management of its fishery. In fisheries science, calculations of longevity, mortality rates and stock-assessment models depend on the availability of growth data.

Genidens genidens was sampled at the Jacarepagua Lagoon system (23° S, 43° W), Rio de Janeiro State, Brazil, using cast nets and beach seines, to study its reproductive biology. Spawning period extended from October to February, but was more intense from December to January, coinciding with high surface water temperature and low salinity in the area ...

High‐salinity water use of euryhaline catfish Genidens genidens revealed by otolith microchemistry
Austral EcologyAbstractMigratory patterns of the catfish Genidens genidens in four estuaries along the Brazilian Atlantic coast are reconstructed from otolith Sr/Ca, a salinity proxy, to test estuarine‐dependency. To facilitate interpretation of this proxy in otolith core‐to‐edge profiles, a Sr/Ca Reference Value for High Salinity (RVHSSr/Ca) of 4.88 mmol/mol was ...

Summary The marine catfish Genidens barbus was once one of the most important estuarine fishery resources in the Patos Lagoon (southern Brazil), which had the largest population known for the species. However, clear signs of overfishing have been observed since the 1980s.

The muscles of the cephalic region and pectoral girdle of Arius heudeloti, Genidens genidens and Bagre marinus are described and compared with those of non-ariid siluriforms. Our observations and comparisons revealed that, although the configuration of the cephalic and pectoral girdle musculature of these ariid species is basically similar to that of ...
