Summarising 40 years of gastric lavage studies to evaluate efficiency and survival in sharks and rays

open access: yesJournal of Fish Biology, EarlyView.
Abstract Traditionally, lethal stomach dissection has been used to study the diets of sharks and rays, but conservation and animal welfare concerns necessitate non‐lethal alternatives, such as gastric lavage (stomach or gut flushing). In this study, we summarised gastric lavage studies on elasmobranchs to identify which species/groups it has been ...

Integrative morphometric and molecular analyses reveal possible genetic contamination of silver catfish populations of the genus Rhamdia in Neotropical River basins

open access: yesJournal of Fish Biology, EarlyView.
Abstract Rhamdia quelen, Rhamdia branneri and Rhamdia voulezi are morphologically similar species that, until recently, were considered synonymous. Although R. quelen has wide distribution in the Neotropical region, R. branneri and R. voulezi are sympatric and endemic species of the Iguaçu River basin.

Unexpected trophic diversity in the endemic fish Orestias chungarensis in a high‐altitude freshwater ecosystem, Lake Chungará (4520 m), northern Chile

open access: yesJournal of Fish Biology, EarlyView.
Abstract Orestias chungarensis Vila & Pinto, 1986 is a small‐bodied (max fork length = 120 mm) cyprinodontiform fish with a very restricted global distribution. The species is limited to a single, small (283 km2), high‐altitude (4520 m) catchment located in the Altiplano of northern Chile. Until the late 20th century, O.
