Method for chemically inducing triploid of thick-shell mussel

The invention provides a method for chemically inducing triploid of thick-shell mussel. By means of the method, stable and efficient triploid induction of the thick-shell mussel is realized. Thick-shell mussel individuals that discharge seminal fluid and thick-shell mussel individuals that ovulate are isolated, sperms and eggs with better quality are conveniently and manually selected, accordingly, the development synchronism of fertilized eggs can be improved, and the induction rate of the triploid can be increased. 6-DMAP (dimethylaminopyridine) is taken as an inducer, the cost is low, the toxicity is low, and the induction rate can reach 65%-75%. 本发明提供种适用于厚壳贻贝的三倍体化学诱导方法，实现对厚壳贻贝稳定、高效的三倍体诱导。本发明将排精或排卵的厚壳贻贝个体隔离，便于人工选择质量较好的精子和卵子，这样做可以提高受精卵发育的同步性和三倍体的诱导率。采用6-DMAP作为诱导剂，费用低、毒性小，且诱导率可以达到65-75％。
