Sand-free rapid breeding method of young palea steindachneri

Abstract

The invention discloses a sand-free rapid breeding method of young palea steindachneri. The sand-free rapid breeding method of the young palea steindachneri including the steps that (1) a plastic breeding box is welded manually, foam plates are arranged around the breeding box for heat preservation, and two round breathable holes are reserved in two ends of the box respectively; (2) palm leaves are put into the breeding box, and new palm leaves are added continuously along with growth of the palea steindachneri; (3) the temperature inside the breeding box is controlled to be 28+ / -1 DEG C through temperature control equipment; (4) the young palea steindachneri 8-10 grams heavy are put into the breeding box in the morning or at the afternoon with the density being 25-30 per square meter, and the young palea steindachneri are all put at a time; (5) water is changed every morning and afternoon, and the palm leaves are cleaned when water is changed; (6) minced fillet and mixed feed are cast once at 8:30 and 17:30 after water changing. The palm leaves are arranged, so that the young palea steindachneri can rest on the palm leaves and are prevented from fighting with and biting each other, enough feed is cast on time to prevent the young palea steindachneri from scrambling for the feed and fighting with and biting each other, a constant temperature breeding method improves the feed conversion ratio, breeding of the young palea steindachneri is attended by people, the survival rate is improved, and the growth speed is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a sand-free rapid culture method for soft-shelled soft-shelled turtle seedlings. Background technique [0002] The Tyrannosaurus soft-shelled turtle belongs to the class Reptiles, Turtles, Turtleidae, and the genus Triton. It is mainly distributed in Guangxi in southern China and Vietnam in Southeast Asia. Shanrui soft-shelled turtle has large body, good meat quality, remarkable nourishing effect, and high breeding efficiency. It is one of the popular species of soft-shelled turtle breeding at present. It has developed into a characteristic breeding species in Guangxi, with an annual breeding output value of 300 million yuan. Shanrui soft-shelled turtles are timid by nature. They like to drill into the mud and sand, exposing only their nostrils to breathe, and only climb out of the mud and sand to look for food when they are hungry. They are good at fighting, competing for f...

AI Technical Summary

Problems solved by technology

Turtle seedlings hide in the sand and only come out to look for food when they are hungry, resulting in less food intake and slow growth; due to low temperature and low feed conversion rate, soft-shelled turtle seedlings grow slowly, and it takes 2-3 years to grow to 1 kg

Sediment culture, water quality is difficult to control, easy to breed bacteria, prone to diseases, the survival rate of 1 kg of soft-shelled turtles grown from 8-10 grams of soft-shelled turtle seedlings is less than 70%
