Monthly differences in the movement ecology of lake whitefish (Coregonus clupeaformis) in eastern Lake Ontario

Journal of Fish Biology, EarlyView.
Abstract Lake whitefish are a cold‐water species that holds cultural and economic importance throughout the Great Lakes region. Anthropogenic stressors over the last 60 years (e.g., invasive species, habitat degradation, and pollution) have caused significant declines in their populations.

Prospección acústico-pesquera y caracterización ambiental de algunos recursos de tipo demersal en el Caribe colombiano

Intropica, 2004
En el marco del programa de pesca Vecep (Inpa-Colombia) se llevó a cabo una campaña piloto de reconocimiento acustico de los fondos y de recursos demersales, previa a la evaluación por área barrida realizada por ese mismo programa.  La campaña se realizó

Fish landings and Oman shelf area

Journal of Agricultural and Marine Sciences, 2016
Data from five field surveys carried out along the shelf in the 20-250m depth range and historical data on artisanal fishery were analyzed. A positive linear relationship between the demersal fish biomass and the shelf area was pronounced for a certain ...

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments

Journal of Fish Biology, EarlyView.
Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

Current state of stocks for demersal fish on the continental shelf in the exclusive economic zone of Russia in the northwestern Bering Sea

Известия ТИНРО, 2016
Stocks of demersal fishes on the depths of 20-200 m in the northwestern Bering Sea are considered, excluding walleye pollock Theragra chalcogramma , on the data of 10 bottom trawl surveys conducted in the summer-fall of 1985-2015.

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

Journal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

Journal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.
