Effective sampling of marine communities is essential to provide robust estimates of species richness and abundance. Baited Remote Underwater Video Stations (BRUVS) are a useful tool in assessment of fish assemblages, but research on the optimal sampling

Evidence of tide pool use by a viviparous elasmobranch as a parturition site [PDF]
Despite the frequent occurrence of elasmobranchs in surf zones, the use of tidal pools by these animals is unknown, with only one incidental observation reported in the literature.

Strengthening Angel Shark Conservation in the Northeastern Mediterranean Sea
Angel sharks are among the most threatened species of sharks globally. Twenty-two species have been identified globally so far, with three species being present in the Mediterranean Sea: Squatina aculeata, Squatina oculata, and Squatina squatina.

A socio‐psychological approach for understanding and managing bycatch in small‐scale fisheries
Fisheries bycatch is the greatest threat to migratory, long‐lived marine animals. Addressing bycatch ultimately requires changing fisher behaviour, yet social and behavioural sciences are rarely applied to bycatch mitigation, with an absence of theory ...

Catch Composition, Seasonality, and Biological Aspects of Sharks Caught in the Ecuadorian Pacific
Although sharks have a fundamental role in maintaining the balance of aquatic ecosystems, exerting a great influence on lower levels of the food chain, their populations are declining worldwide due, to a large extent, to overfishing.

Acute-stress situations in vertebrates induce a series of physiological responses to cope with the event. While common secondary stress responses include increased catabolism and osmoregulatory imbalances, specific processes depend on the taxa.
