| Abstract: |
Rainbow trout (Oncorhynchus mykiss Walbaum, 1792) farming is the only promising cold water aquaculture in Nepal, but its
farming is constrained by availability of quality and quantity of feed. An experiment was done to evaluate the performance
of locally formulated low cost nutritious feeds for rainbow trout fry at Fisheries Research Center, Trishuli for 3 months.
The experiment included four treatments i) T1- control, shrimp based feed, ii) T2 - shrimp+amino acids based feed, iii) T3 -
shrimp+stinging nettle based feed, and iv) T4 - silkworm based feed. Each treatment was replicated thrice. Fry was stocked
in raceways of 1 m2
at 200 fry/m2
density and fed at the satiation for 6 times in a day from 7.00 am to 5.00 pm. Proximate
analysis showed that crude protein was 42.8% in T1, 42.0% in T2, 41.7% in T3 and 39.8% in T4 feeds. Growth of fry and
food conversion ratio were significantly better (p
respective feeds while feed cost was significantly (p
and gross margin T1 feed was found to be better among experimental feeds. |
