| Abstract: | Sinperca chuatsi refuse to eat dead prey or man-made feed.However,experiments with long-term cul-tivation suggest that S.chuatsi can be domesticated to feed on inert baits.Selective breeding of S.chuatsi using molecular markers and mass cultivation with artificial feed reduces the problems associated with cost,contamina-tion,and disease.Pepsinogen is an acid gaster-digestion hydrolase which digests proteins under acidic conditions.Acidic proleases are sometimes used as additives in animal feed as they promo... |
