What kind of caves should be dug for farmed baby fish? What kind of pool to build?

The shape of the salamander at all stages of the pond is better to be rectangular or oval, the ratio of length to width is 3:2, and its height is required to be two to three times the total length of the giant salamander farmed.

OK!!! How to raise baby fish.

1. The living habits of the salamander The salamander likes a dark, cool, and flowing water environment. It feeds on a wide range of animals, and its larvae feed on zooplankton and aquatic insects. As the individual grows up, it gradually preys on tadpoles, frogs, fish, crabs, and even water birds and mutton.

In the case of lack of food, the large doll negative also devours the larvae of the same kind. The baby fish has a ferocious temperament, a large mouth, and three rows of teeth up and down, and if it is not well mastered, it will bite.

Second, the breeding method of baby fish.

1) Have a good water environment: water with large alkali content or turbid water is extremely harmful to salamander, so the water quality should be clean. The water temperature should be 14 18 and the water depth should be 30cm.

2) Build a dark cavern: It is necessary to use stone and cement mortar to build an arch cave, and an air-raid shelter with a good water source can also be used. The size of the arch is determined according to the size of the rearing. The specifications of the arch are generally: 30m long, 2 5m wide, and 2 5m high.

3) Feeding pond: The feeding pond of baby fish should be built in the arch hole. It is better to divide the left and right rows, with a sidewalk in the middle, and build a square or rectangular pool with bricks.

The height of the pool is 1m, and the surrounding and bottom of the pool are smoothed with cement. The size of the ponds varies in size, with 2 square meters, 4 square meters, 6 square meters, 10 square meters or larger, so that the size can be kept separately. Each pool should be set up with a water level hole (or spillway, the hole is 35cm high, which is convenient for drainage and water level control.

Each pool should be installed with a water inlet pipe, and the diameter of the pipe depends on the size of the area of the feeding tank. Each inlet pipe is fitted with a faucet to regulate the amount of water. At the bottom of the pond, there are movable stone slab holes for the salamander to perch.

4) To master the feeding management methods: summer and autumn feeding with frogs as the main bait, winter and spring with mutton as the main bait. The feeding time is 1 time in the morning and 1 time in the evening, and the amount of feeding should be determined according to the season and feeding capacity.

1 7kg of concentrate is required for each 1kg of baby fish long. Generally, less bait is given in winter, more in spring, and more bait in summer and autumn. It is better to feed fresh, live bait.

In addition, management should be strengthened, so that the pond should be patrolled frequently, observed frequently, inspected frequently, cleaned up the pond frequently, found problems in time, dealt with them quickly, and disinfected with drugs in time when fish diseases occur.
