Body Length, Tow Conditions, and Guide-Net Angle as Joint Predictive Contributors to Catch Loss in a Marine Mammal Bycatch Reduction Device: An Interpretable Machine Learning Analysis

Fishes
Guide-net marine mammal bycatch reduction devices (BRDs) are intended to reduce protected species interactions in trawl fisheries, but their use may also cause catch loss of commercial fish and cephalopods.

Feeding Habits and Prey Composition of Six Mesopelagic Fish Species from an Isolated Central Mediterranean Basin

Fishes
Mesopelagic fishes hold an important position in marine food webs, serving as a link between lower trophic levels and top predators and transferring energy from their deep mesopelagic habitat to shallower oceanic layers.

Distribution and abundance of large pelagic predatory bony fishes in the northwestern Pacific over a half-century

Water Biology and Security
Large pelagic predatory fishes play an important role in marine ecosystems, occupying the highest position in food webs and accumulating energy and organic matter produced by aquatic organisms of lower trophic levels. Among pelagic predatory fishes, more

An assessment of dolphin behaviour and bycatch mitigation techniques in the Pilbara Fish Trawl Fishery, Western Australia [PDF]

, 2009
The incidental capture of unwanted species along with target species is a common and wasteful aspect of many fisheries. Trawl fisheries in particular have a high rate of incidental capture, or bycatch, due to the low selectivity of their nets.
