SEA-FISHERIES LABORATORY. 247 



(1) 13 herrings caught in Kevin Bay, Carnarvon Bay, 

 one mile from shore in three fathoms on December 1st, 



1905— 



8 were spent females ; 



5 were spent males. 

 In all cases the stomachs were empty. 



(2) 12 herrings caught off New Quay on December 

 4th, 1905, at night— 



1 was a spent female ; 



3 were spent males ; 



4 were full females; 



4 were full males. 



All the stomachs were empty. 



(3) 12 herrings caught close inshore in Nevin Bay, 

 Carnarvon Bay, on sand and on gravel on 13th December, 

 1905— 



5 were spent females ; 

 3 were spent males ; 



1 was a full female ; 

 3 were full males. 

 All the stomachs were empty. 



These results are extremely interesting. It is 

 evident that full herring are to be found off the Welsh 

 coast in Avinter, and probabl) T deposit their spawn there. 

 It is most desirable that samples of herring from all the 

 Welsh fisheries should be obtained and examined. 



5. Sea temperature and catches of Whitings. 



The connection between hydrographical observations 



and the abundance of food fishes is well illustrated* by a 



discussion of the sea temperature and the catcEes of 



haddock made by steam trawlers fishing off Grant on on 



the East coast of Scotland. A curve is given in the
