Method for regulating and controlling breeding density of platysternidae

Abstract

The invention discloses a method for regulating and controlling the breeding density of platysternidae. The invention provides a method for regulating and controlling the breeding density of platysternidae on the basis of years of breeding experimental researches. Compared with the prior art, the method has the advantages that the eco-biological characteristics such as field behaviors, back sunning behaviors, feeding behavior characteristics, habitat environment characteristics and the like are considered fully; according to the method, the problem of density regulation and control in the manual breeding process of platysternidae can be solved effectively, under the condition of fully utilizing the cultivation space and water resource, the fighting behaviors of platysternidae under a group breeding condition are reduced remarkably, the probability of dying and deformity events is controlled below 5 percent, the spawning rate of reproducible female platysternidae can be up to 80 percent, healthy growth of platysternidae of different sizes is ensured, and the breeding efficiency is increased; the method has the advantages of remarkable effect, easiness in operating, saving of resources and cost and contribution to popularizing and applying.

Description

Technical field: [0001] The invention belongs to the field of biological technology, and in particular relates to a control method for breeding density of ratites. Background technique: [0002] Flat-breasted turtle (Platysternon megacephalum) is a rare and economical freshwater turtle native to Asia. It has delicious meat and important edible and medicinal value. For a long time, due to overhunting and trade, wild resources have declined sharply, causing the flat-breasted turtle to become an endangered species. In response to market demand, the artificial domestication and breeding of ratites can not only effectively expand the population, avoid species extinction, but also help protect wild resources and achieve sustainable use of resources. As an excellent new species of freshwater turtle breeding, flat-breasted turtle breeding has attracted more and more attention from the aquaculture industry. [0003] However, there are still many technical problems to be solved in t...

AI Technical Summary

Problems solved by technology

Flat-breasted turtles belong to freshwater turtles with territorial behavior. They are fierce and aggressive. They are significantly different from other gregarious freshwater turtles in their living habits. Once the breeding density is too high, they are prone to fighting behavior due to competition for territory, resulting in slow growth. , sickness and disability, and seriously affect mating and breeding activities and healthy growth; and if the breeding density is too low, it will waste breeding space and water resources, increase costs, and reduce breeding benefits

At present, due to the lack of theoretical guidance, there is a lot of blindness in the control of the artificial breeding density of the ratites, which seriously restricts the development of the breeding industry of the ratites
