Trophic redundancy in benthic fish food webs increases with scarcity of prey items, in the Southern Baltic Sea

Frontiers in Marine Science, 2023
Bottom trawling is one of the main pressures on benthic ecosystems, directly impacting the targeted species and physically disturbing the seabed and the benthic invertebrate communities, in turn indirectly impacting benthivorous fish and the entire ...

Demersal fish in Icelandic waters

, 2021
A sudden increase in population size and distribution around Iceland took place in several species in 2000-2010. What they have in common is that Iceland is placed at the northern border of their geographic range making the susceptible to environmental fluctuations.

DEMERSAL FISHING ANALYSIS OF KUPANG BAY [PDF]

Marine Research in Indonesia, 1970
Study on demersal fish in Kupang bay was carried for 6 months, from July 2002 to December 2002. Sampling was conducted twice a month at the ten-selected locations within the bay using different fishing gears such as gill net, bottom logline, hand line and traps.

Fish assemblages associated with natural and anthropogenically-modified habitats in a marine embayment: Comparison of baited videos and opera-house traps [PDF]

, 2013
Marine embayments and estuaries play an important role in the ecology and life history of many fish species. Cockburn Sound is one of a relative paucity of marine embayments on the west coast of Australia.

Demersal Fish Assemblages in NE Atlantic Seagrass and Kelp

Diversity, 2020
Global fisheries are in decline, calling for urgent evidence-based action. One such action is the identification and protection of fishery-associated habitats such as seagrass meadows and kelp forests, both of which have suffered long-term loss and ...

Using hydrodynamics to modify fishing performance of a demersal fishing gear

Fisheries Research, 2023
This study demonstrates how hydrodynamics can be used to influence the fishing performance of towed demersal fishing gears. Sea trials are performed in the sea star fishery to show how modifications to the gear design alter the hydrodynamics of the turbulent wake and consequently affect the catching performance of trawl gears.
