Problems solved by technology

[0002] In the soft-shelled turtle breeding production, the soft-shelled turtle spawning ground is usually covered with a layer of yellow sand on the shore of the soft-shelled turtle pond for soft-shelled turtles to spawn. Due to the limitation of the environmental conditions of the spawning ground, the spawning rate is low, which affects the breeding efficiency

Embodiment

[0010] Two spawning grounds are established on the north bank of each turtle-friendly pond, respectively A field and B field. One side of the turtle pond has a slope of 20-30 degrees, and the other three sides form a guardrail and are covered with a rainproof shed. The spawning ground is laid with 20-30 cm thick river sand.

[0011] On the first day, open the A field to lay eggs, and close the door of the A field when patrolling the pond in the morning, so that the eggs laid that night will not move in the sand, and collect after 8-30 hours after all the embryos in the eggs have been fixed; close the A field At the same time, open the B field to lay eggs and use them in a circular manner; the egg collection starts at 4 pm after the soft-shelled turtles have finished eating, and the egg collection box is used. The bottom of the egg collection box is covered with 2-5 cm thick fine sand, and the eggs are pressed by the animal poles. Neatly arranged face up in the box.

Abstract

The invention discloses a soft-shelled turtle spawning site and relates to the technical field of aquaculture. The soft-shelled turtle spawning site comprises parent turtle ponds. The soft-shelled turtle spawning site is characterized in that each parent turtle pond comprises a spawning site A and a spawning site B, the area of each spawning site is one tenth of that of the corresponding parent turtle pond, the spawning sites are disposed on the north coast of the corresponding parent turtle pond, each spawning site is square, the gradient of one side, close to the corresponding parent turtle pond, of each spawning site is 20-30 degrees, guardrails are formed on the other three sides provided with rainproof covers, and 20-30cm of river sand is laid on each spawning site. The soft-shelled turtle spawning site has the advantages that the ideal spawning environments are provided for parent turtles, the soft-shelled turtles are not affected by the outside during spawning, and culture benefits are increased; every two spawning sites can be used alternatively, embryo fixation of soft-shelled turtle spawns is increased favorably, and interference to the spawning soft-shelled turtles is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a soft-shelled turtle spawning ground. Background technique [0002] In the soft-shelled turtle breeding production, the soft-shelled turtle spawning ground is usually covered with a layer of yellow sand on the shore of the soft-shelled turtle pond for soft-shelled turtles to spawn. Due to the limitation of the environmental conditions of the spawning ground, the spawning rate is low, which affects the breeding efficiency . Contents of the invention [0003] The purpose of this invention is to provide a soft-shelled turtle spawning ground, to solve the above technical problems. [0004] The technical problem to be solved by the present invention is realized by the following technical solutions. [0005] A kind of soft-shelled turtle spawning ground, comprises pro-turtle pond, is characterized in that, two spawning grounds are set up in each pro-turtle pond, is respectivel...
