Now it has been one of the most important aquatic products in the freshwater cultivation. however, this prawn ca n ' t survive at a water temperature lower than 14c, which has seriously limited its cultivation expanding. in order to obta in a new breed of this prawn with increased cold - resistance, we investigated the cloning of a synthetic gene ( sbwafp ) based on the primary sequence of the mature spruce budworm ( choristoneura fumiferana ) antifreeze protein ( sbwafp ) and the integration of sbwafp into the embryo genomes of giant freshwater prawn by spermatophore - microinjection ( smi ), a sperm - mediated gene transfer technique
