The invention relates to a large-scale breeding method for odontobutis potamophila based on timely
temperature control. The method specifically includes the following steps that (1), parent fishes arebred before production, wherein waterweeds are transplanted in a parent fish culture
pool, palaemonetes sinensis is put in the
pool, and meanwhile odontobutis potamophila parents are added accordingto the ratio of males to females; (2), an environment is created, wherein fresh snails are put in to improve the
water quality; (3), an artificial laying
nest is arranged, wherein two arc green tilesare bundled relatively to form the tubular artificial laying
nest; (4), artificial spawning is performed, wherein when it is found that eggs are attached onto the artificial laying
nest, water in thepool is drained through pumping, the odontobutis potamophila parents are caught, a spawning
pool is built, and oxytocins are injected into the odontobutis potamophila parents; (5), timely temperaturecontrol is performed for incubation, wherein when growing to the
neurulation stage, embryos are timely transferred into a room for temperature-controlled incubation. The method reduces the
adverse effect of
environmental stress on
embryo development at the early stage of incubation of fertilized eggs; compared with temperature-controlled incubation conducted in the whole process, the energy can besaved by 73%, the
deformity rate is reduced by 8%, the incubation rate of the fertilized eggs is improved by 11%, and the
incubation period in the method can be shortened by 5-7 days compared with the normal-temperature
incubation period.
