Deep demersal fishes in the Canary Islands
, 1993 Some remarks about deep-sea demersal species of fishes captured in fishery prospections from La Gomera, Gran Canaria and Tenerife (Canary Islands) between 300-2500 m depth are given. Long-lines and experimental traps were used during the cruises.

Journal of Fish Biology, EarlyView.Abstract We used an ecological niche theory framework integrating physiological and behavioural ecology to understand interspecific differentiation of juveniles of four Antarctic fishes: Trematomus bernacchii, Trematomus pennellii, Trematomus nicolai and Pagothenia borchgrevinki.

The impacts of environmental forcing on the dynamics of demersal fishery resources of Ghana [PDF]
The dynamics of demersal fish species assemblages and stocks on the continental shelf of Ghana, West Africa were investigated using data from trawl surveys conducted between 1963 and 1990, and in relation to marine environmental and nearshore forcing ...

Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour
Journal of Fish Biology, EarlyView.Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

Journal of Fish Biology, EarlyView.Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Status of demersal fishery resources in the Gulf of Thailand [PDF]
Data from trawl surveys (1961 - 95) and annual production statistics (1971 - 95) were used to examine the status of demersal fishery resources in the Gulf of Thailand.

Length-Weight Relationships of Demersal Fishes from the South China Sea of Malaysia
, 2020 This study attempts to look into the length weight relationship of demersal fish species collected from the South China Sea of Malaysia. Demersal fish species from wild were captured, total length and weight of each fish were measured, and gonads were ...

Challenges in licensing the industrial double-rig trawl fisheries in Brazil
Latin American Journal of Aquatic Research, 2015 Bottom trawling is important in Brazilian fisheries and is currently highly multi-specific due to the overexploitation of the original targets; unselective fishing method; very large permitted fishing area and the country's high marine biodiversity ...

Journal of Fish Biology, EarlyView.Abstract Intragastric gavage is widely used in studies of digestive physiology to deliver standardised meals, yet it remains unclear whether it elicits postprandial metabolic and acid–base responses comparable to voluntary feeding. Here, we tested whether the method of meal delivery affects the magnitude and timing of the postprandial rise in metabolic

Diet Analysis of North Central Gulf of Mexico Demersal Shelf Fishes, March 2015-December 2016
, 2017 Diet analyses of demersal reef fishes (n= 2,351) collected in the north central Gulf of Mexico between March 2015 and December 2015. We performed visual gut content identification for all identifiable prey and DNA barcoding for unidentifiable (i.e ...
