(1), to the loach parent manual injection oxytocins chosen, after 24 ~ 36 hours, distinguish one from the other male and female, carry out conventional taking-up sperm and the step of ovum respectively; Then ovum and sperm are carried out artificial insemination, put into conventional cultivation pond hatching;
(2), then whole loach parents is placed on the screen cloth in separate tank, support at least 24h temporarily again, in during supporting temporarily, have that part is delayed to be reached sexually matured loach parent and understand Natural excrement sperm and ovum and be fertilized, fertilized egg can the slight whirlpool that formed by scroll apparatus for converting to focus in the middle of cement pit and to sink;
(3) fertilized egg of, collecting in separate tank to flow to the water inlet of collecting pit along with current from the delivery port of separate tank; The bolting silk net network interface of collecting pit water inlet is superfine, can by sweep away with current come fertilized egg all collect, bolting silk net collect fertilized egg put into again cultivate pond hatch.
As the further improvement of described hatching m, also comprise step (4): utilize water circulating pump to be again pumped in separate tank by the water in collecting pit, realize recycling of water resource.
compared with prior art, tool has the following advantages the utility model:
Loach parent through taking out ovum and sperm step is put into separate tank by the utility model, through foster a period of time makes whole loach parents all reach sexual maturity temporarily, and then put back to culturing pool, ensure that sperm and the ovum of loach parent are all discharged, and be effectively separated with parent, improve incubation rate, add profit, and hatch simple to operate, be convenient to aquaculture management.
Accompanying drawing explanation
