Abstract	The feed attraction properties of squid and prawn for cod were investigated in two growth experiments using a feed based on minced saithe fillet, of which 10% on a protein-energy basis was exchanged for squid or cooked prawn, compared with a control group given minced squid mantle as the protein source. Both additions increased growth and feed consumption over the basic saithe feed from 6&100%, giving the same effect as the control feed of squid mantle. A protein digestihility of 85% and fat digestibility of 90% was found. The liver index was between 6.5 and 9.5% with fat energy contents of 13 to 20% in the feeds. The feed attractants improved nutrient retentions as shown by the values for feed conversion, PER and PPV. It was concluded that feed attractants are hrneficial additions to feeds of marine fish species, and cheap marine products locally available may be preferred over chemicals such as free amino acids and other nitrogenous compounds.
