The possibility of using crustacean waste products (CWP) on rainbow trout (Oncorhynchus mykiss) feeding

Öz:

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 artık ürünlerle beslenen alabalığın en yüksek ağırlık kazancı sağladığını göstermiştir. Ayrıca, düşük oranda protein içeren yeme CWP’nin fazla miktarda eklenmesinin bu yemle beslenen alabalığın iştahını ve büyümesini olumsuz bir yönde etkilemediği gözlenmiştir. %47 protein ve CWP içeren yem ile beslenen balıkların yem değerlendirme oranı (FCR) 0.79 ve oransal ağırlık artışı markalı balıklar (balıkları bireysel olarak tanımak için verilen işaretler) için 123.87 ve tüm stock için 147.57 olarak bulunmuştur. Elde edilen sonuçlar, CWP’nin gökkuşağı alabalığı yemi üretiminde kullanılan balık ununa alternatif protein kaynağı olarak kullanılabilineceğininin kullanıldığında sadece amino asit ilavesi gerektiğini göstermiştir.

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.
