1. three-element crossed breeding method for Japanese scallop, it is characterized in that:

  • the Patinopecten yessoensis colony parent shellfish of choosing the Patinopecten yessoensis colony in the Patinopecten yessoensis colony in Russian marine site, Chinese marine site, Japanese marine site is respectively cultivated crossbreeding as the parent, comprises the steps;

    A, elder generation carry out the artificial culture accelerating to the Patinopecten yessoensis colony in Russian marine site, and a day intensification is controlled at 0.2~

    0.4 ℃

    , and wherein the effective accumulated temperature of the more conventional accelerating of effective accumulated temperature many 30~

    50 is subsisted, and breeding method is thrown in bait routinely;

    B, again to the Patinopecten yessoensis colony in Chinese marine site routinely the accelerating mode carry out the artificial culture accelerating, make it to reach gonad maturity synchronously with the Patinopecten yessoensis colony in Russian marine site;

    C, the Patinopecten yessoensis colony that above-mentioned a, b step are cultivated utilize heating mode to stimulate and hasten parturition, collect sperm and the ovum of the smooth scallop of the two seed shrimps parent of colony shellfish respectively;

    D, mating fertilization, hybridize by the female shellfish ovum in the male shellfish sperm in the male shellfish sperm in the female shellfish ovum in Chinese marine site and Russian marine site or Chinese marine site and Russian marine site and to obtain hybridizing the first filial generation smooth scallop of Sino-Russian or Russia-Sino two seed shrimps colony, and the suspended longline farming mode was formed in 2 years routinely;

    E, the Patinopecten yessoensis colony that chooses Japanese marine site and above-mentioned hybridization the first filial generation Sino-Russian or Russia-Sino Patinopecten yessoensis colony that forms that obtains carry out the artificial culture accelerating as the parent, synchronize them to reach gonad maturity;

    F, the Patinopecten yessoensis colony that reaches gonad maturity that then the e step is cultivated utilize heating mode to stimulate and hasten parturition, and collect the Sino-Russian or Russia-Sino parent of two Patinopecten yessoensis colonies shellfish ovum, sperm and the Japanese Patinopecten yessoensis parent of colony shellfish ovum, sperm respectively;

    G, mating fertilization in such a way;

    Sino-Russian female shellfish ovum and Japanese male shellfish sperm or Russia-Sino female shellfish ovum and Japanese male shellfish sperm are hybridized, or Sino-Russian male shellfish sperm and Japanese female shellfish ovum or Russia-Sino male shellfish sperm and Japanese female shellfish ovum are hybridized, obtain Sino-Russian day or Russia-Sino day of three way cross first filial generation or day Sino-Russian or Japan-Russia in a plurality of Patinopecten yessoensis colony, conventional buoyant raft is formed, and the gained Patinopecten yessoensis is China, Russia and Japanese three geographical population three way cross Patinopecten yessoensis according to specific mating method hybridization.
