Gadus virens, Linn. — Green Cod. 



Eggs which were probably identical with those of 

 the green cod were first noticed in the Bay plankton in 

 1914 on January 28th. They occurred throughout the 

 whole of February, and once in March, the 31st. A haul 

 taken on February 26th contained 114 eggs identified as 

 Gadus virens. Green cod eggs were present in only one of 

 the collections taken outside the Bay, but this is probably 

 due to the spawning period of the fish being over before 

 the " Intensive Study " investigation of the outside area 

 commenced. None were found in the plankton from the 

 Gentral area of the Irish Sea. 



Gadus luscus, Will. — Bib. 

 Gadus minutus, Linn. — Poor Cod. 



Eggs of both these species of fish occur in the 

 plankton of the Irish Sea, but the difference in size is 

 so very slight that it is almost impossible to separate
