Culure method for green turtles at three months old or younger

Abstract

The invention discloses a culture method for green turtles at three months old or younger. The culture method is characterized by comprising the following steps of culture pond improving, wherein a culture pond of the green turtles is obtained by improving a sea shrimp culture pond, the periphery of the sea shrimp culture pond is improved into slopes, a fence is built around the pond, and the improved culture pond is exposed under the sun for 3 days or above; seawater pretreating, wherein standing and precipitating are conducted on seawater for 10-12 h; pond entering of the seawater, wherein the pretreated seawater is guided into the culture pond, and the water surface in the pond is 0.3-0.5 m lower than the highest portion of the culture pond; young turtle stocking, wherein young green turtles are put into the culture pond, the young turtle density is controlled to be 100-120/m<3>, and the young turtles are cultured for 30-35 days; density lowering, wherein after the young turtles are cultured for 30-35 days, part of the green turtles are transferred to other culture ponds, and the green turtle density is controlled to be 30-40/m<3>; culture managing, wherein managing in the culture process of the green turtles comprises feeding, water changing, water temperature managing and diseased turtle clearing. According to the method, by reasonably controlling the density of the turtles, the feeding frequency and the bait proportion, the survival rate of the green turtles is 95% or above.

Description

technical field [0001] The invention belongs to the technical field of sea turtle breeding, and in particular relates to a method for raising green sea turtles under the age of three months. Background technique [0002] Green sea turtle: Also known as sea turtle, it is the largest of all kinds of sea turtles.
