Water fish breeding methods and technologies

In fact, the turtle that people usually call is a soft-shelled turtle. It likes quietness and is afraid of being startled. It likes the sun and is afraid of wind. It likes cleanliness and is afraid of dirt. The most suitable water temperature is 15~17℃. Its diet is very diverse, but it mainly feeds on carnivorous food. It likes to eat animal feed such as snails, river shrimps, and small fish. Next, I will take you to learn about aquatic fish breeding methods and techniques.

1. Conditions for turtle breeding

1. Pond conditions

The pond area should be about 5 mu, with a slope ratio of 1:2, a flat bottom, silt thickness of about 25 cm, and a water depth of 1.8 to 2.5 meters.

2. Water source requirements

The water source is sufficient, the water quality is good and pollution-free, and it meets the fish farming standards, with a pH value of 7-8.5 and a dissolved oxygen content of more than 5 mg/L.

3. Escape prevention facilities

A 40-centimeter-high escape-proof wall is built around the wall, with the top of the wall inclined 10 centimeters inward and the inner wall smooth to prevent the turtle from escaping and the invasion of enemies.

4. Sun terrace construction

A feeding table 15 to 25 centimeters above the water surface is built in every 200 square meters of pond, with one side slanted and extending 20 to 30 centimeters underwater.

2. Turtle breeding and management

1. Bait preparation

It is mainly composed of animal protein and supplemented by plant protein, and uses fresh bait such as small fish, animal offal, green fodder such as aquatic plants, fruits and vegetables, or a mixture of wheat bran , corn flour, and bean dregs.

2. Feeding

Start feeding when the water temperature is above 18℃, and the daily feeding amount is 10-20% (fresh animal bait) or 5% ( compound feed ) of the total weight of the turtle.

3. Feeding skills

Adhere to the principle of "four determinations and four observations", and choose fixed feeding areas on both sides of the pond for feeding, which is convenient for observation and adjustment.

4. Water level adjustment

The initial water level is 80 to 100 cm, and it gradually deepens with the water temperature and individual growth. New water is added once every half a month in spring and autumn, and once a week in summer.

5. Water quality control

Sprinkle quicklime or bleaching powder regularly to maintain the dissolved oxygen, pH value and ammonia nitrogen within the appropriate range, and use an aerator when necessary.

6. Daily management

Inspect the pond every morning and evening, observe the turtle's activities, feeding and growth, adjust the feeding amount, remove residues and maintain water quality.

7. Suggestions for purchasing soft-shelled turtle fry

Choose turtle fry that have been raised for more than one day after hatching, and avoid buying those that are hatched on the same day to reduce breeding risks.

Turtle farming is favored by farmers because of its high economic value. The above are the conditions and key points of turtle farming and feeding management, which will help farmers to effectively carry out turtle farming.
