Haddock {Gaclus ccglefinus). 



32 stomachs of Haddock were examined of which 9 

 were empty, and 1 contained unrecognisable food matter, 

 leaving 22 to be accounted for. 



Crustacea were found in 12 stomachs, or fully 54 %. 



Fish were found in 6 stomachs, or fully 27 %. 



Mollusca were found in 3 stomachs, or fully 13 %. 



Annelida were found in 2 stomachs, or fully 9 %. 



From last year's Eeport it will be seen that Mollusca 

 occupied the first place with fully 54 %, Echinoderms 

 second with 21 %, Annelida and Crustacea third with 

 fully 18 % each. 



Thornback Skate (Bala clavata). 



17 stomachs were examined of which 4 were empty, and 

 1 contained unrecognisable animal matter, leaving 12 to 

 be accounted for as having contained recognisable food 

 material. 



Crustacea were found in 8 stomachs, or fully 66 %. 



Mollusca were found in 3 stomachs, or 25 %. 



Fish were also found in 3 stomachs, 25 %. 



Last year's report shows that fully 97 % of the stomachs 

 of the Skate contained Crustacea, Mollusca occupying 

 second place with 16 %, and Fish third with 10 %, so that 

 as far as our results go they show that the Thornback 

 Skate in our district feed largely upon Crustacea such as 

 Crangon, Carcinus, Galathea, Hyas, Nephrops, Portunits, 

 PagiLTUs and a species of Amphipoda, probably Ampelisca 

 spinipes, Boeck. 



We have also examined the stomachs of a number of 

 other more or less important food fishes, such as the 

 ** Lemon Sole " {Pleuronectes microcephaliis), " Long 

 Rough Dab" {Hippoglossoides limandoides) , " Grey Gur- 

 nard" {Trigla gurnardus), " Starr}^ Eay " [Raia radiata), 

 " Grey Skate " {Baia batis), but not in sufficient numbers 

 to make them worth while recording.
