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

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.

Contribution to the study of cod Gadus morhua

2015
Traceability is one of the most used tools to control fish origin and can contribute to improve product quality and safety. However, until now the methods used to identify the fish origin and its chemical and biological characteristics involve the loss of commercial value of the fish sampled.

Growth of North Sea cod, Gadus morhua

Netherlands Journal of Sea Research, 1974
Abstract As part of a study of consumption and production of North Sea cod an analysis is presented of the growth of North Sea cod, utilising market sampling, research vessel survey, and tagging data. Bertalanffy growth curves were estimated from market samples for the southern and northern North Sea separately.

[The parasitization of Gadus morhua in the southern Baltic Sea].

Applied parasitology, 1993
During a survey of the working group 25 of BMB in the south of the Baltic Sea in October 1991 105 cod (Gadus morhua L.) were investigated for parasites (ICES Subdivision Areas 22, 24, 25 and 26). They were parasitized by 15 species. With increasing salinity (from east to west) and in the higher size groups more parasite species were present.
