Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary. [PDF]
J Fish BiolAbstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Evaluation of different induced molting methods in Callinectes ornatus (Crustacea, Decapoda, Portunidae) as a tool for the commercial production of soft-shell crabs [PDF]
Anais da Academia Brasileira de Ciências, 2021 We investigated the effects of eyestalk ablation and cheliped autotomy in inducing molting in Callinectes ornatus. The specimens in intermolt stage were divided into two size classes: 1 (30-50 mm) and 2 (51-70 mm) and were further divided into four ...
