Distribution and feeding habits of three sea robin species (Bellator brachychir, Prionotus nudigula and Prionotus punctatus) in the Campos Basin, southeastern Brazil
The distribution, size structure, and feeding of three sea robin species belonging to the family Triglidae (Bellator brachychir, Prionotus nudigula and Prionotus punctatus) were studied based on specimens caught with bottom trawls on the continental shelf of Campos Basin, southeastern Brazil. The tw...
