What determines growth potential and juvenile quality of farmed fish species? [PDF]

open access: yes, 2013
Enhanced production of high quality and healthy fry is a key target for a successful and competitive expansion of the aquaculture industry. Although large quantities of fish larvae are produced, survival rates are often low or highly variable and growth ...

Post‐Release Mortality of European Bass (Dicentrarchus labrax) Discarded From Small‐Scale Estuarine Fishing

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas.

Implications of fisheries during the spawning season for the sustainable management and recovery of depleted fish stocks: life history characteristics of several North Sea species [PDF]

open access: yes, 2009
Fish traders and NGOs have put the idea forward that in order to not disturb the spawning process and hence improve the reproductive success of a fish population one should stop fishing during the spawning period.

Ossification of Atlantic cod ( Gadus morhua ) – Developmental stages revisited [PDF]

open access: yesAquaculture, 2017
Abstract In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose a set of five developmental stages of Atlantic cod from start-feeding until the juvenile stage, based on cranial ...

Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Haemoglobin revisited: delineating population structure with the world’s first molecular genetic marker used in fisheries research

open access: yesRoyal Society Open Science
When haemoglobin genotyping was implemented in the early 1960s to investigate population genetic structure in Atlantic cod (Gadus morhua), it became one of the first molecular genetic markers deployed in fisheries research worldwide.

Heavy metals in Southern Baltic fish: present situation and future trends [PDF]

open access: yesActa Ichthyologica et Piscatoria, 1991
Herring (Clupea harengus) and cod (Gadus morhua) from three Southern Baltic areas were studied. Mercury content was determined with CV AAS and assays of the remaining metals were carried out with flame AAS.

Hemoglobin genotype has minimal influence on the physiological response of juvenile atlantic cod (Gadus morhua) to environmental challenges

open access: yes, 2009
Hemoglobin (Hb) polymorphism in cod is associated with temperature‐related differences in biogeographical distribution, and several authors have suggested that functional characteristics of the various hemoglobin isoforms (HbIs) directly influence ...

Joint Spatiotemporal Models for the Estimation of Prey Consumption and Predator–Prey Overlap: Dynamics of Pacific Cod Predation on Snow and Tanner Crab in the Eastern Bering Sea

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Pacific cod (Gadus macrocephalus) are important predators of juvenile snow (Chionoecetes opilio) and Tanner crab (Chionoecetes bairdi) in the eastern Bering Sea (EBS), yet the relationship between cod–crab spatial overlap and total crab consumption is only partially understood.

A note on stomach contents of minke whales (Balaenoptera acutorostrata) in Icelandic waters

open access: yesNAMMCO Scientific Publications, 2000
There is limited available information on food habits of minke whales (Balaenoptera acutorostrata) in coastal Iceland. Sixty-eight minke whales were examined for stomach contents; 51.5% contained fish only, 22.1 % krill (Euphausiacea) only, 25.0% fish ...
