According to the unique ecological habits of the giant salamander, the habitat habits and ecological environment needed for growth and development of the salamander are to be considered when designing the fish farm.
(1) The overall planning of the farm The growth of the giant salamander is divided into the seedling stage, the juvenile stage, the adult stage, and the brood stage. It must be reared in different stages of growth and different breeding purposes.
1. Various types of aquaculture ponds
(1) Note drainage pool. Including the pool, reservoir, sedimentation tank, filter tank.
(2) Aquaculture ponds. Seedling pond, an area of ​​about 20 square meters, larval pool, an area of ​​30 to 40 square meters; adult pool of about 150 square meters; broodstock pool of 30 square meters; hatching pool of 10 square meters; isolation pool of 10 square meters.
2. Drainage works must have a complete water injection and drainage system. Water injection projects generally have water pumps, water purification facilities, shrink pipes and so on. Each aquaculture pond should have a water shutoff switch.
3. Farming machinery systems mainly include aerators, feed processing units, water pumps, motors, and direct-cooled air-conditioning units;
4. Production, living area offices, dormitories, laboratories, cold stores, warehouses, tool rooms, garages, etc.
(b) The design and construction of aquaculture ponds There are two types of ponds for the cultivation of pterodactyl fish: one is for open-air breeding ponds, the other is for civil defense projects and the rearing of basements.
1. Aquaculture pond structure
(1) The requirements of the structure of the pool wall: First, no water leakage; Second, it is safe and secure, the bottom of the pool does not sink, and the pool wall does not break; Third, there must be anti-escape facilities.
(2) The bottom structure of the pool is generally tamped with stones, with a thickness of 20 to 30 cm, filled with small stone slag, and finally paved with concrete. In order to facilitate drainage, the bottom of the pool is inclined from the inlet to the outlet, and the floor of the pool is covered with a tile.
(3) The inlet and drain of the inlet and the drain are located at the pool angle. The water inlet is higher than the wall of the pool and the filter and control valve must be set. The drain outlet should be 8.5cm below the bottom of the pool and a control valve and metal escape protection should be installed.
2. Construction of aquaculture pond The construction of a doll pond is to be determined according to its ecological requirements and culture methods. A standardized farm should build seedling pools, larval pools, adult pools, broodstock pools, and hatching pools.
(1) Seedling pools and freshly emerged seedlings have not completed metamorphosis. They are delicate, have poor resilience, and have weak ability to adapt to the environment. The construction of seedling ponds is more demanding. The outlet is 5 cm lower than the bottom of the pool for drainage and drainage: the outlet diameter is about 5 cm. Walls and pool bottoms should be tiled and kept smooth. Water outlets should be fenced with stainless nets to prevent escape;
(2) The larval pool and the adult pool: The requirements for the aquaculture pond construction are basically the same as that of the seedling pool, with an area of ​​50-150 square meters. The water outlet and inlet are determined by the amount of water in the pool. Because both larvae and adults have cave habitat habits, the pool should be installed for their inhabited stones, pebbles built caverns. The caves made of stones and pebbles account for two-thirds of the pool area.
(3) The nucleus pool is required to be built indoors. The basic construction and facilities of the broodstock pool is the same as that of the adult, but one additional equipment, namely the flushing equipment, is required. Natural baby dolls are mature in the flowing water environment. Therefore, when artificially fostering broods, flushing stimulation is required to make the gonadal gonads mature. This will help increase the artificial reproduction rate.
