A Comparative Trial for Raising Several Species of Hybrid Sturgeon in Reservoir Cage

In the period of Shandong agricultural seed engineering project " Suitable Sturgeon Formalization Raising and Industrialization Development" implementation, a comparative trial for raising hybrid sturgeon in reservoir cage had been carried on, using several species of hybrid sturgeon, such as the two-hybrid(Acipenser schrencki ♀×A.baerii ♂), the small-hybrid(A.ruthenus ♀×A.schrencki ♂), three-hybrids(A.schrencki ♀× Bester ♂), Russia hybrid sturgeon(A.schrencki ♀×A.gueldenstaedti ♂), the counter-hybrid(A.baerii ♀×A.schrencki ♂), the big-hybrid(A.baerii ♀×Huso dauricus ♂) .It also had used two domestic sturgeon feed(feed A and feed B)for comparative trial.According to the test data, the two-hybrid, the big-hybrid, the counter-hybrid , the small-hybrid have a better result, but there is a certain problem for the three-hybrid and the Russian hybrid.Feed A is better than feed B in feed protein efficiency, group relatively grown rate and group weight grown rate, but feed A is inferior to feed B in feed economic efficiency.
