SEA-FISHERIES LABORATORY. 145 



Second Day.— The vessel will steam south to the 

 deep water lying south and south-west of the Calf 

 Island, which we know to be the spawning ground of 

 cod, hake, haddock, and other fish. Three hauls with 

 the fish trawl and one with the shrimp trawl should be 

 taken along lines running north and south in water of 

 depths of from 30 to 50 fathoms. Plankton nets and 

 physical observations as before. Yessel to lie for night, 

 according to weather, in Port vSt. Mary, Port Erin, or 

 Piel harbours. 



Third Day. — The vessel will steam to deep water 

 lying west of Isle of Man, and take two hauls of the 

 fish trawl and one of the shrimp net on the " reamy " 

 ground, where the sole, the turbot, and the brill spawn, 

 at depths of 30 to 50 fathoms, and one haul of the fish 

 trawl on the mud at a depth of TO to 80 fathoms. The 

 vessel will then run further to the north and take two 

 drags in the middle of the channel between Point of 

 Ayre and the Mull of Galloway, at a depth of 20 to 

 30 fathoms. Plankton and physical observations as 



before at each station. 



Fourth Day. — After spending the night at either Peel 

 or Ramsey, according to the wind, the vessel will trawl 

 from Ayre Point towards St. Bees Head, along the 

 20 fathom line, and then south from King William's 

 Bank in the muddy depression of over 20 fathoms, also 

 along the Bahama Bank, off Maughold Head. Two 

 hauls of the fish trawl should be taken at each of these 

 localities. Plankton and physical observations as before. 



That finishes the statistical trawling investigation for 

 that week, and the vessel will then, according to circum- 

 stances, either return to Fleetwood to land material 

 and refit, or will stay out longer exploring the spawn- 

 ing grounds, etc., and doing other general faunistic work.
