Özet:

 

Crustacean waste product (CWP) generated from the fishing industry could be used in diets  for rainbow trout as an alternative animal protein. Some experiments have been undertaken with  penaid species, showing that it is possible to partially replace fish meal with CWP in penaid feeds. This  study has been designed to assess whether CWP could be used to partially replace fish meal in diets  for rainbow trout. The results show that CWP improved the digestibility of the diet, yielding the  highest performance, and also that the addition of large amounts of CWP to a low-protein diet did not  depress appetite. Fish fed on a diet containing 47% protein and CWP had a feed conversion ratio of  0.79 and a percentage weight gain of 123.87 for marked fish and 147.57 for the whole stock. These  results indicate that CWP may be recommended for use as an alternative to fish meal sparing in  rainbow trout diets, but that partial replacement requires amino acid supplementation.
