The carbohydrate moiety of serum IgM from Atlantic cod (Gadus morhua L.).

Comparison of immunoglobulin (IgM) from four fish species

Immunoglobulin (IgM) was isolated from the serum of four fish species, Atlantic salmon (Salmo salar L.), halibut (Hippoglossus hippoglossus L.), haddock (Melanogrammus aeglefinus L.) and cod (Gadus morhua L.) and a comparison made of some physical and biochemical properties. The molecular weight of IgM varied between the different species and between the different analytical methods used. IgM f...

The behavioural and physiological response of Atlantic cod Gadus morhua L. to short-term acute hypoxia

The average rate of swimming speed and the physiological status or stress of individual Atlantic cod Gadus morhua was monitored in response to short-term acute (STA) hypoxia (i.e. partial pressure of oxygen, PO2 , reduced from 20 9 to 4 3 kPa within 1 h at 10° C). The STA hypoxic response of Atlantic cod was associated with a large primary increase (þ29%) and a large secondary decrease ( 54%) i...

The ontogenic development of innate immune parameters of cod (Gadus morhua L.).

The aim of this study was to monitor the ontogenic development of innate immune parameters of cod (Gadus morhua L.) and to determine the presence of maternal IgM. The general protein composition and enzyme activity was also studied. At intervals, samples were collected of fertilized cod eggs and larvae from 3 days after fertilization until 57 days after hatching. Cell lysates were prepared and ...
