Plasma calcium and calcitonin in the marine teleost, Gadus morhua

Comparative Biochemistry and Physiology Part A: Physiology, 1985
Total, free and ionic plasma levels of calcium as well as total plasma magnesium and inorganic phosphate levels were studied in the Atlantic cod, Gadus morhua, in relation to salmon calcitonin injections. Plasma ion levels and endogenous levels of calcitonin were studied during environmentally induced hypercalcemia.

Stages of embryonic development in the Atlantic cod Gadus morhua

Journal of Morphology, 2004
AbstractThe early development of the Atlantic cod, Gadus morhua was studied from fertilization until first‐feeding. Multiple families were reared at 7°C and a developmental staging series was prepared using morphological landmarks visible with the light microscope. Stages were named rather than numbered to allow for future additions and broadly grouped

The Response Of Young Cod (Gadus Morhua) To Environmental Gradients

2001
No abstracts are to be cited without prior reference to the author.The ability of fish to select an optimal habitat allow to respond to inappropriate environmental factors and in doing so to improve the physiological conditions. Fish react to almost every conceivable environmental factor.

Differentiation of Atlantic cod Gadus morhua morhua and pacific cod Gadus morhua macrocephalus by electrophoresis and by isoelectric focusing of water-soluble proteins of muscle tissue

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1981
Abstract 1. 1. The water-soluble proteins of the skeletal muscle of Atlantic cod Gadus morhua morhua and Pacific cod Gadus morhua macrocephalus have been examined by electrophoresis and by isoelectric focusing in polyacrylamide gel. 2. 2. The species were readily differentiated either by electrophoresis or by isoelectric focusing.

The Effect Of Energetic Condition On Growth In Cod (Gadus Morhua)

2001
No abstracts are to be cited without prior reference to the author.Following periods of weight losses due to food shortages, refed fish experience a period of fast growth which may compensate for negative growth periods. Prolonged starvation was hypothesized to have a detrimental effect on the growth capacity of fish with sub-lethal condition factor ...

Field potentials in the olfactory bulb of the codfish (Gadus morhua)

Comparative Biochemistry and Physiology Part A: Physiology, 1976
Abstract 1. 1. Field potentials were evoked in the olfactory bulb of the cod by electrical stimulation of the main afferent and efferent pathways. 2. 2. The waveforms evoked by both routes of stimulation were similar, consisting of two negative waves followed by a slow positive potential. 3. 3.

Cod (Gadus morhua) in subdivisions 22–24

2022
ICES advises on the basis of the MSY approach that the total commercial catches should be no more than 8793 tonnes in 2015. Measures should be implemented to protect the local spawners in Subdivision 22.

Cod (Gadus morhua) in Division 3a (Kattegat)

2022
 ICES  advises  that  when  the  precautionary  approach  is  applied,  catches  in  2016  should  be  no  more  than  536  tonnes. If this stock is not under the EU landing obligation in 2016 and discard rates do not change from 2014, this implies landings of no more than 130 tonnes

Cod (Gadus morhua) in Subdivision 21 (Kattegat)

2019
ICES advises on the basis of precautionary considerations that there should be no directed fisheries and bycatch and discards should be minimised.

The spawning activity of cod, Gadus morhua L.

Journal of Fish Biology, 1989
Aspects of the reproduction of reared cod, Gadus morhua L., with special emphasis on the females, were studied under laboratory conditions. The fecundity and condition factor were 2–5 and 1–5 times, respectively, that of wild cod. A total of 18 spawning females were kept in separate tanks/ chambers, each with one or two males.
