The invention relates to a selection and culture method of excellent
breed large-tooth
flounder featuring fast growth and
high survival rate. The technical method comprises: culture and
reproduction regulation and control of large-tooth
flounder breeding group, establishment of family by
sperm freezing technology, culture and
standardization of the family, determination and analysis of number and properties,
estimation of genetic parameters, screening of excellent family, and establishment of excellent
breed by inducing thelykaryon of large-tooth
flounder to develop by using
heterologous frozen sperms. The invention can select and culture new
breed of cultured large-tooth flounder featuring fast growth and
high survival rate, screen out four excellent large-tooth flounder families featuring fast growth and
high survival rate (0703, 0719, 0750 and 0751), and establish seven excellent breeds of large-tooth flounder developed from thelykaryon (0920, 0921, 0927, 0938, 0939, 0946 and 0947). The technical method can be applied to new variety culture of large-tooth flounder cultivation, solve the problems of culturing large-tooth flounder fish in sea water such as
slow growth and low
survival rate, and enhances economic benefit of large-tooth flounder cultivation.
