The invention discloses an autumn
procambarus clarkii egg-carrying
shrimp breeding facility and method, and belongs to the technical field of
procambarus clarkii egg-carrying
shrimp breeding.
Crayfish parents are cultivated through VE
nutrition enhancement,
gonad development is promoted, and the physique and
immunity of the parent crayfishes are enhanced; the illumination and the
water temperature are reduced, the
water temperature is regulated and controlled to induce the crayfishes to lay eggs and carry eggs outside the holes, and the
egg laying synchronization rate of the parent crayfishes is increased and reaches about 80%; a net cage breeding facility is arranged, so that the crayfishes lay eggs outside the caves, and the crayfishes carrying eggs can be conveniently caught in a centralized mode; the square belts are spliced along the
flowerpot to create a
cave structure so as to provide a hidden environment for the parent shrimps; through pond bottom
sludge removal before net cage arrangement, quicklime disinfection, pond bottom
exposure, box body washing, water changing, microecological preparation and substrate modifier use and the like in the breeding period, substrate and
water quality are kept to be good, the problems that the
water quality of the net cage is prone to deterioration and the like are solved, the
survival rate of seed shrimps is increased, the yield of autumn breeding egg-carrying shrimps is increased, and an egg-carrying
shrimp source is provided for
hatching of egg-carrying young shrimps.
