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 and a percentage weight gain of for marked fish and 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.

Eklem Bacaklı Artıklarının Gökkuşağı Alabalığının (Oncorhynchus mykiss) Beslenmesinde Kullanım Olasılığı Özet: Balıkçılık endüstrisinden gelen kabuklu hayvanlarının (örneğin; karides, yengeç vb.) artık ürünleri (CWP), yani tüketime sunulmayan kısımları gökkuşağı alabalığı yeminde alternatif hayvansal protein kaynağı olarak kullanılabilir. Penaid türleri ile yapılan bazı araştırmalar bunun mümkün olduğunu göstermiştir. Bu araştırma, CWP’nin alabalık yeminde kullanılan balık unu yerine kullanılıp kullanılmayacağını değerlendirmek için yapılmıştır. Elde edilen sonuçlar, CWP’nin yemin sindirilme oranını artırdığını, bu .
