Fisheries Management and Ecology, EarlyView.ABSTRACT The recreational fishery for pollack (Pollachius pollachius) in the northeast Atlantic is impacted by the species' high sensitivity to barotrauma. When captured at depth and brought to the surface, gas expansion within the peritoneal cavity can cause a variety of injuries and hinder release.

Fisheries Management and Ecology, EarlyView.ABSTRACT Bycatch remains a critical challenge in global fisheries, even when using selective gears such as longlines. In the French longline fishery targeting Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of Lion, the common pelagic stingray (Pteroplatytrygon violacea) is the primary bycatch species.

Combined effect of ocean acidification and bottom trawling on embryo size of the scleractinian cold-water-coral Desmophyllum pertusum [PDF]
We report the results of a series of experiments investigating the combined effects of ocean acidification and suspended natural benthic sediments (NS) generated during bottom trawling on the early life stages of the cold-water coral Desmophyllum ...

Effects of chronic bottom trawling on benthic macrofaunal communities [PDF]
, 2020 Marine sediments constitute one of the largest ecosystems on earth. The animal life which inhabit these environments are known as benthic fauna, and represent a remarkable range of taxonomic and functional diversity.

The effective swept volume of a bottom trawl
, 2004 No abstracts are to be cited without prior reference to the author.The reaction of individual fish towards an approaching trawling vessel has previously been measured using target-tracking methods. In this paper these measured velocities are fitted to a deterministic mean behaviour model and a diffusion-advection model taking the random component into ...

Management Implications of Mesopelagic Forage Fisheries for Bigeye Tuna Stocks
Fisheries Management and Ecology, EarlyView.ABSTRACT Many large marine predators forage on mesopelagic fish stocks, including commercially valuable tunas. The mesopelagic is under increasing interest for commercial exploitation, given its large biomass with potential to supply fishmeal for aquaculture feed or fish oil.

The substantial first impact of bottom fishing on rare biodiversity hotspots: a dilemma for evidence-based conservation [PDF]
, 2013 The present study set out to describe the impact of a single first passage of two types of bottom fishing gear on rare protected shellfish beds formed by the horse mussel Modiolus modiolus.

Fisheries Management and Ecology, EarlyView.ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho
Fisheries Management and Ecology, EarlyView.ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.
