| Abstract: | Objective] The model of high yield and high-efficiency crap(Ctenopharyngodon idellus) fry multiplication was explored based on the improvement of its survival rate.Method] 36 000 fingerlings with the body length of 3.3 cm were raised in the soil pond with the area of 2 668 m2 with the compound feed and duckweed.Results] reeding high-yield experiment of grass crap(Ctenopharyngodon idellus) juvenile culture conducted in a.Stocking with body length of,which were fed with pelleted feeds together with for 150 days.The overall yield of 3 240 kg fishes with the body weight of 100 g/each was obtained and the survival rate of grass carp was 90%.And the ratio of input and output was 1.0∶2.7 and the total profit was 30 184 yuan,which was considerable economic benefit.Conclusion] The cost was reduced and the survival rate of grass carp-raising was increased with the compound feed and duckweed,which could be extended in actual production. |
