Understanding the reasons why intraspecific diversity arises and how populations adapt to spatial variation in environmental conditions continues to be a major focus of evolutionary biology. Recently, inversion polymorphisms have become an active area of research focused on unde…

Intensive aquaculture of Atlantic cod is fast developing in both Northern Europe and Canada. The last six years have seen major improvements in the larval rearing protocols and husbandry techniques for this species. Although breeding programmes are currently being developed by b…
Traditionally, fish meal (FM) and fish oil (FO) have been used extensively in aquafeeds, mainly due to their excellent nutritional properties. However, various reasons dictate the use of sustainable alternatives and the reduction of the dependence on these commodities in fish fe…
Cod hatcheries rely greatly on wild-caught broodstock as egg quality from farm-reared broodstock tends to be poor. Broodstock diet and levels of essential fatty acids have been linked to fecundity and egg quality in cod. Arachidonic acid (ARA) and astaxanthin (Ax) are important …
Atlantic cod (Gadus morhua L.) is one of the most promising new fish species introduced to cold water aquaculture due to the large established market in Europe and the USA and the decline in wild stock. So far, the production of farmed cod has been relatively low, with the main …
Aquaculture is an essential developing sector for world food production, however the attainment of sexual maturity during commercial on-growing is a major bottleneck to industry expansion. Sexual maturation brings a commercial loss due to reduced growth performance as well as re…
