State-dependent energy allocation in cod (Gadus morhua)
Growth and maturation are processes that are tuned to the external environment that an individual is likely to experience, where food availability, the mortality regime, and events necessary to complete the life cycle are of special importance. Understanding what influences life history strategies and how changes in life history in turn influence population dynamics and ecological interactions ...
متن کاملClick sounds produced by cod (Gadus morhua).
Conspicuous sonic click sounds were recorded in the presence of cod (Gadus morhua), together with either harp seals (Pagophilus groenlandicus), hooded seals (Cystophora cristata) or a human diver in a pool. Similar sounds were never recorded in the presence of salmon (Salmo salar) together with either seal species, or from either seal or fish species when kept separately in the pool. It is conc...
متن کاملExophiala angulospora causes systemic inflammation in atlantic cod Gadus morhua.
Species of Exophiala are opportunistic fungal pathogens that may infect a broad range of warm- and cold-blooded animals, including salmonids and Atlantic cod. In the present study, we observed abnormal swimming behaviour and skin pigmentation and increased mortality in cod kept in an indoor tank. Necropsy revealed foci of different sizes with a greyish to brownish colour in internal organs of d...
متن کاملExcess post-hypoxic oxygen consumption in Atlantic cod Gadus morhua.
Atlantic cod Gadus morhua experienced oxygen deficit ( D O 2 ) when exposed to oxygen levels below their critical level (c. 73% of pcrit ) and subsequent excess post-hypoxic oxygen consumption (CEPHO ) upon return to normoxic conditions, indicative of an oxygen debt. The mean ± s.e. CEPHO : D O 2 was 6·9 ± 1·5, suggesting that resorting to anaerobic energy production in severe hypoxia is energe...
متن کاملIodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
