New techniques and matters needing attention in culture of soft-shelled turtle

Culture ponds: it is appropriate to choose quiet and sunny places to build new turtle ponds, juvenile turtle ponds, juvenile turtle ponds, 3-year-old turtle ponds and adult turtle ponds. Selection of seedlings: you can choose and buy high-quality seedlings in formal farms or aquaculture markets, and raise them in cages for 15 days before stocking. Temperature: do not exceed 32 ℃. Feed: you can choose animal feed and plant feed. Feed: the weight should be moderate. Water quality management: water needs to be changed every other week, and a small number of plants such as water hyacinth and water hyacinth can be planted to improve water quality.

Soft-shelled turtles like quiet, sunny, clean living environment, hate noise, windy, polluted environment, the shape of soft-shelled turtle is oval, its back and limbs are dark green, but some of the back is light brown, the abdomen is very white and you can see a little red.

I. Construction of soft-shelled turtle pond

The main results are as follows: 1. To build a pond, we should choose a pond with a quiet environment, no wind and sun, and convenient drainage and irrigation. if the turtle farm is self-propagated, self-reared and self-raised, five kinds of culture ponds should be constructed. they are new turtle ponds, juvenile turtle ponds, 3-year-old turtle ponds and adult turtle ponds.

2. The soil of the pond had better be clay or loam. If there is no sandy soil at the bottom of the pond, it should be mixed with a part of sandy soil. A sun table and bait platform should be built on the edge of the pond to provide a place for soft-shelled turtles to bask and ingest food. Around the pond, asbestos tiles and bricks are used to build an anti-escape wall with a height of 1m.

2. Selection and stocking of soft-shelled turtle fry

The choice of seedlings: to order in the regular farm or in the local aquatic market, you can also order online, but you must be careful not to buy them in the hands of small vendors, because the size of the soft-shelled turtle seedlings in the hands of the vendors is inconsistent. The source channel is not clear, and the purchased soft-shelled turtle is easy to get sick and die.

Stocking: no matter where the soft-shelled turtle fry bought can not be immediately put into the culture pond, it is necessary to temporarily culture the soft-shelled turtle through the cage for about 15 days. To observe the situation of the soft-shelled turtle, you can first put part of the soft-shelled turtle into the cage in the culture pond for about 15 days. If the soft-shelled turtle does not have any discomfort or abnormality, it can carry out large-scale stocking, and the stocking density depends on the size of the culture pond and other factors. 2-3-year-old juvenile soft-shelled turtle 100kg-150kg can be put per mu.

Third, temperature control

The most suitable temperature for the growth of soft-shelled turtle is 30 ℃-32 ℃, and the food intake of soft-shelled turtle is proportional to the temperature, but the highest temperature should not exceed 32 ℃, and the temperature should be kept stable as far as possible.

Fourth, the choice of feed

1. Animal feed: the feed of soft-shelled turtle can use the viscera of livestock and poultry discarded by the hotel, leftover leftovers from cooking, and snails, small fish, shrimp and Loach caught in paddy fields or river ditches, as well as earthworms and insects in the fields.

2. Plant feed: a small amount of plant bait, such as corn meal, bean dregs, melons and fruits, and wheat bran, can be added to the soft-shelled turtle feed.

V. Feed feeding

When using fresh feed, it must be disinfected and cleaned, and should be eaten now to avoid feed corruption and deterioration. When putting feed, it should be fed away from the 2cm-3cm on the surface of the water. This is because the soft-shelled turtle is timid, and the interference to them should be minimized when feeding. The feed should be controlled in an hour and a half to finish. In the hot season, feed should be fed before sunrise and sunset.

VI. Water quality management

The soft-shelled turtle has strict requirements on water quality, because most of the soft-shelled turtle lives in the water, and the quality of the water quality is very important to the growth of the soft-shelled turtle, so it is necessary to change the water every 8-10 days. When changing the water, the water level in the culture pond should be excluded from 20cm-25cm, and then the water should be filled up. The transparency of the water in the culture pond should be controlled at 30cm-35cm.

The water in the adult turtle pond should be changed every 4 days, and a small amount of green plants such as water lotus and water hyacinth can be planted in the water, which can improve the water quality and make the soft-shelled turtle grow better.

VII. matters needing attention

1. Make a daily inspection in the morning and evening to check the situation of the anti-escape wall and the enemy, and to understand the eating and water quality of the soft-shelled turtle.

2. The bait-fed pool should be cleaned with a small irritating disinfectant or a sterilized brush before each feeding, and should be disinfected every three days.
