Mauremys mutica egg hatching method

Abstract

The invention discloses a mauremys mutica egg hatching method. According to the method, no medium such as sand or vermiculite is needed, and mauremys mutica eggs are hatched directly. The biggest advantage of the method is that the method is simple. With the method, observation is convenient; hatching manpower can be reduced; hatching cost can be reduced; air can be ventilated; and pathogen infection changes are reduced. The hatching temperature is higher by 2-3 DEG C than that of a method adopting a medium. The hatching time is approximately 60 days. A hatching rate reaches 98%.

Description

technical field [0001] The invention relates to a method for hatching eggs of aquatic animals, in particular to a method for hatching eggs of stone turtles. Background technique [0002] Stone turtle meat is delicious and nutritious, and is very popular among consumers. Its docile temperament is suitable for large-scale group breeding, and its characteristics of easy management and high efficiency have quickly become the first choice for turtle garden breeding. In recent years, Guangdong, Guangxi and other southern regions are gradually expanding the scale of breeding. Artificially raised stone turtles reach sexual maturity after about 4 years, and generally start to lay eggs in mid-April, and basically stop laying eggs in late August. Most of the turtle eggs raised artificially adopt the method of artificial hatching. Put the fertilized eggs in the hatching tank, spread 3 cm thick wet fine sand or vermiculite, then lay a layer of eggs, and then cover them with 3 cm wet fin...

Problems solved by technology

This hatching method requires a large amount of sand or vermiculite as a medium, which increases production costs and consumes manpower, and uses sand or vermiculite as a medium for hatching, which is susceptible to bacterial infection and affects the hatching quality.
