Crossbreeding is a powerful tool for improving productivity and profitability in aquaculture. We conducted a pilot study of an artificial cross between two important cultivated scallops in China, Chlamys farreri and Mimachlamys nobilis, to test the feasibility of interspecific hybridization. Reciprocal hybridization experiments were performed using a single-pair mating strategy (M. nobilis ♀ × ...

Genetic variation and inheritance of randomly amplified polymorphic DNA (RAPD) markers in female grass carp (Ctenopharyngodon idella) and male bighead carp (Hypophthalmichthys nobilis) and their F1 offspring hybrid have been studied. For this purpose, genomic DNA was extracted from muscle tissue according to phenol-chloroform method, and six decamer primers were used for amplifying polymorphic ...

In order to reasonably use of the aristichthys nobilis scale resources, gelatin was extracted from the scales of aristichthys nobilis with the aid of ultrasonic method. The ultrasonic power, time, temperature and the ratio of material to solvent on extraction of gelatin from aristichthys nobilis scales were studied. The ultrasonic extraction conditions of gelatin from aristichthys nobilis scale...
