Bathymetric groupings of demersal fishes on the slope and outer shelf at the oceanic side of southern Kuril Islands in spring season

open access: yesИзвестия ТИНРО, 2014
Abundance and species composition are investigated for demersal fish at the oceanic side of southern Kuril Islands on the data of the bottom trawl survey in the depth range 100-1400 m conducted in the spring of 2009 (for the first time at the continental

Trophic interactions and distribution of some Squaliforme sharks, including new diet descriptions for Deania calcea and Squalus acanthias. [PDF]

open access: yesPLoS ONE, 2013
Squaliforme sharks are a common but relatively vulnerable bycatch in many deep water fisheries. Eleven species of squaliforme shark are commonly caught at depths of 200-1200 m on Chatham Rise, New Zealand, and their diversity suggests they might occupy ...

Length-weight relationships of demersal fishes from the upper continental slope off Colombia [PDF]

open access: yes, 2000
Parameters of the length–weight relationship of the form W=aLb are presented for 45 demersal fish species caught on the upper continental slope of the Caribbean Sea off Colombia. The b values varied between 2.13 and 4.97, with the mean b = 3.042 (95% CI,

A Comparison between Two Sonic Measuring Systems for Demersal Fish [PDF]

open access: yesJournal of the Fisheries Research Board of Canada, 1970
Two sonic methods for estimation of abundance of fish stocks, the echo integrator and the digital counter methods, were compared on single and schooling fish in the Lofoten area of Norway during March 1969. Good correlation was obtained between the two systems for both situations, but the slopes of the regressions of integrated values on the digital ...

Revisiting Maturity Data: Using Oocyte Diameter and Gonadosomatic Index to Retroactively Apply a New Maturity Scale to Greenland Halibut (Reinhardtius hippoglossoides)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Greenland halibut (Reinhardtius hippoglossoides) is a deep‐water flatfish which lives at temperatures of 1°C–4°C and produces large eggs (> 3 mm). The combination of low temperatures and large eggs has resulted in an unusual ovary development cycle, with vitellogenesis taking more than 1 year.

Recompression Improves Release Success in Pollack (Pollachius pollachius): A Step Towards Assessing Post Release Mortality in a Recreational Fishery

open access: yesFisheries 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.

Fine-scale proximity to offshore wind turbine foundations increases biomass of demersal fish species

open access: yesFrontiers in Marine Science
Offshore wind turbine fixed-bottom foundations provide artificial hard substrate through the water column that encourages marine flora and fauna to colonise and aggregate around the introduced structures, a well-documented phenomenon known as the ...

A preliminary investigation of the Marine Ichthyofauna in the Tsitsikamma Coastal National Park

open access: yesKoedoe: African Protected Area Conservation and Science, 1984
Sixty-five species representing 29 families were re- corded in a survey of the marine ichthyofauna of the Tsitsikamma Coastal National Park. Visual assessments of the composition of the fish communities at three inshore reef types indicated differences
