Gadus callarius, Linn. — Cod. 



The pelagic eggs of the cod are generally to be found 

 in small numbers in the plankton taken inside the break- 

 water at Port Erin between the end of February and 

 April. They are no doubt carried into the Bay by winds 

 and currents. It is scarcely likely that spawning will 

 take place in the shallow water of the Bay. Cod eggs 

 are moderately abundant at times outside the Bay from 

 a few miles West of Bradda Head to South of Calf 

 Island. Some of the collections taken at Station III 

 have been estimated to contain from 865 to 1,590 cod 

 eggs. The first cod eggs appeared in the Bay on 

 February 26th. Throughout the next two months very 

 few of the bi-weekly hauls in the Bay, and outside of it, 

 were without the eggs of this fish. Plankton collected 

 10 miles off Point Lynus on February 5th contained Rye 

 cod eggs. Another sample from 11 miles N. by E. of the 

 Liverpool North-West Lightship, on February 17th, 

 contained three eggs. The hauls made in the central 

 area of the Irish Sea and in Carnarvon Bay in April 

 showed cod eggs to be generally distributed.

 the South-West of the Isle of Man in 1914: —
