Problems solved by technology

However, in the process of artificial breeding of soft-shelled turtles, problems such as excessive hormones, additives, and unreasonable use of drugs have caused problems such as excessive growth of soft-shelled soft-shelled turtles, although the growth rate of artificially raised soft-shelled turtles is fast, but the quality is reduced, and the medicinal value is also reduced, which is not in line with people's pursuit of food safety and The demand for environmental protection has caused the market price to plummet, and the economic benefits of raising soft-shelled turtles are declining day by day

Embodiment 1

[0028] The soft-shelled turtle ecological reproduction method comprises the following steps: seed selection, feed selection, egg collection, hatching management;

[0029] The selection is to select wild soft-shelled turtles with a body weight of more than 1.5kg and no disease or injury, the ratio of male to female is 3:1, and the stocking density is 200 / mu;

[0030] The feed is selected as feed mainly fresh small fish, shrimps, snails, mussels, and animal offal, supplemented by plant-based bait organisms, and the daily feeding amount accounts for 7% of the total body weight of soft-shelled turtles;

[0031] Said ovum collection is before ovum collection, spread 1cm thick fine sand at the bottom of the egg collection box; in the spawning season, dig out the fertilized eggs in the sand pile of the spawning field, lightly put the fertilized eggs into the egg collection box and arrange them neatly; After the eggs are collected, the fertilized eggs are covered with fine sand.

Embodiment 2

[0039] The soft-shelled turtle ecological reproduction method comprises the following steps: seed selection, feed selection, egg collection, hatching management;

[0040] The selection is to select wild soft-shelled turtles with a body weight of more than 1.5kg, no disease and no injury, the ratio of male to female is 4:1, and the stocking density is 300 / mu;

[0041] The feed is selected as feed mainly fresh small fish, shrimps, snails, mussels, and animal offal, supplemented by plant-based bait organisms, and the daily feeding amount accounts for 8% of the total body weight of soft-shelled turtles;

[0042] Said ovum collection is before ovum collection, lay 3cm thick fine sand at the bottom of the egg collection box; in the spawning season, dig out the fertilized eggs in the sand pile of the spawning field, lightly put the fertilized eggs into the egg collection box and arrange them neatly; After the eggs are collected, the fertilized eggs are covered with fine sand.

Abstract

The present invention discloses an ecological reproduction method for soft-shelled turtles, belonging to the field of aquaculture. The method comprises the following steps of: breed selection, feed selection, egg collection and incubation management. The breed selection refers to selecting wild soft-shelled turtles each of which weighs equal to or greater than 1.5 kg and has no diseases or injuries, wherein the ratio of female to male is 3-4:1, and the stocking density is 200 turtles / mu to 300 turtles / mu. The feed selection refers to selecting feed mainly comprising fresh fish, shrimps, spiral-shelled mollusks, mussels and animal innards, and supplemented by plant food organisms, with the daily ration being 7%-8% of the total weight of the soft-shelled turtles. The egg collection refers to laying 1 cm to 3 cm thick sand on the bottom of egg collecting boxes before egg collection. During the spawning season, fertilized eggs are dig out of sandpiles of spawning grounds, and the fertilized eggs are placed in the egg collecting boxes with care and arranged neatly. After the egg collection, the fertilized eggs are covered by find sand. The technique means can increase the medicinal value of the soft-shelled turtles, increase the hatching rate of the multiplication of the soft-shelled turtles, yield strong larvae and improve economic benefits for producers.

Description

technical field [0001] The invention relates to the field of aquatic reproduction, in particular to a soft-shelled turtle ecological reproduction method. Background technique [0002] In my country, artificial breeding of soft-shelled turtles has basically formed a set of mature technologies, especially the rapid development of industrialized soft-shelled turtle farming, which has greatly increased the production of soft-shelled turtles. However, in the process of artificial breeding of soft-shelled turtles, problems such as excessive hormones, additives, and unreasonable use of drugs have caused problems such as excessive growth of soft-shelled soft-shelled turtles, although the growth rate of artificially raised soft-shelled turtles is fast, but the quality is reduced, and the medicinal value is also reduced, which is not in line with people's pursuit of food safety and The requirements of environmental protection have caused the market price to plummet, and the economic b...
