The invention relates to a
prawn low dissolved oxygen resistance family
selection method, and belongs to the technical field of
prawn stress-resistance trait selection. The method comprises the steps of
base population establishing; F1 generation family establishing; same
pool culturing;
low dissolved oxygen resistance testing; F2 generation family establishing; continuous generation selecting, wherein different sources of parent prawns are selected to establish a full / half-slib family through directional
mating, common environmental breeding is performed, 94 h
low dissolved oxygen stress is performed, parent selecting and remaining are performed according to the low dissolved
oxygen resistance test result and the growth measure result, after four generations of continuous selection, the family of distant genetic relationship is selected from the families with excellent growth performance and strong low dissolved
oxygen resistance performance, the male and female prawns which are big in individual, strong in vigor and normal in
gonad development are selected to serve as parent to
breed as good varieties. According to the method, the problem occurring in
prawn high-density culturing that the prawns are dead caused by the fact that the prawn growth is influenced by low dissolved
oxygen is solved, and the development of the prawn high-density culture industry is greatly promoted.
