Wild-caught cod were put in cages in May 2006 and fed with either wet feed or a combination of wet feed and dry feed until 16 December. The growth of those who received wet feed (herring / capelin) was good and the fish doubled the weight from 2.2 to 4.3 kg through the experiment. Those who received dry food grew poorly, and after 9 weeks they were put on wet food. This group then had a good growth, and achieved as high an average weight as the wet feed groups at the end of the experiment. Fillet quality in wild cod fed with wet feed changes to a lesser extent through 17 weeks of feeding. Fillet yield is unchanged, the water content has decreased by only 1% while muscle pH dropped from 6.4 to 6.3. The fillet got a slightly firmer texture and a slightly smaller fillet split. Dry feed did not give satisfactory growth in wild-caught cod. This may be due to the feeding system itself, but may also be due to the palatability of the feed. Pre rigor filleting resulted in smaller fillet splitting, as well as a thicker and shorter fillet. Pre rigor filleting also led to a 2% lower fillet yield and a slightly larger liquid loss in the fillet.
