Breeding method of purple apostichopus japonicus

Abstract

The invention provides a breeding method of purple apostichopus japonicus. The breeding method is characterized by collecting purely wild apostichopus japonicus individuals of which the back part and the abdomen part are totally purple, and transplanting the apostichopus japonicus individuals into a breeding pond for carrying out independent separation, temporary rearing and preserving; screening breeding base populations in the middle of May, and carrying out artificial spawning, hatching and breeding; when 30 percent of planktonic larvae develop to be doliolaria, feeding an adhering substrate, changing water and feeding fodder; recording the body color and the growth and development situation of the doliolaria at a fixed period, and screening and weeding out weak individuals; performing an overall breeding process in a purple environment, and strengthening the coloring of young purple apostichopus japonicus by feeding the fodder containing purple natural pigment components in an assisting manner; respectively carrying out selfing on bred F1-generation purple apostichopus japonicus and hybridization on the bred F1-generation purple apostichopus japonicus and preserved base populations, thus forming F2 filial generations, wherein a breeding technology and breeding conditions of the F2 filial generations are the same as those of F1 generations; carrying out three times of high-strength standard breeding, thus obtaining F3-generation new varieties of the purple apostichopus japonicus, wherein the selection and reservation rate is 90 percent or more, and no significant difference of the growing speed and the anti-capability is generated between the F3-generation new varieties of the purple apostichopus japonicus and original apostichopus japonicus.

Description

technical field [0001] The invention relates to seawater culture technology, in particular to a method for breeding purple imitation sea cucumbers.
