What do fish like to eat?

Bouncing fish, also known as bouncing fish, is a kind of warm inshore small bottom fish, which likes to inhabit the high tide area of silt, mud and sand or the estuarine beach of salt water. what does jumping fish like to eat?

What do jumping fish like to eat?

Jumping fish like to eat small crabs, cyanobacteria, diatoms, nematodes, swine flu nematodes, organic detritus, sand mud, protozoa and so on. But mainly phytoplankton or small benthic invertebrates.

Second, how to raise jumping fish?

The main results are as follows: 1. Under the pond condition, the pond for culturing the fish is generally 2 to 10 mu, the bottom of the pond is required to be flat, and the bottom material is better with soft clay, which is favorable for the fish to drill holes. The bottom of the pool should be higher than the low tide line of the sea area to facilitate draining water and drying the flat. The cross trench is dug in the middle of the pool, and a circular edge ditch is opened along the pool to form the word "field". The ditch is generally 2 meters wide and 30 centimeters deep, making it easy to protect the bullet-coated fish when draining and sunbathing. It is better to separate the intake and drainage of the pond and connect the central ditch. The bottom of the pond is inclined from the intake gate to the drainage gate. The bottom of the drainage gate should be about 20 cm lower than the bottom of the intake gate to facilitate the drainage of the pool. Anti-escape facilities are installed around the intake and drainage gates and ponds.

2. Half a month before pond cleaning and disinfection and stocking, drain the pond water first, sun the flat continuously for several days, until the surface of the flat is cracked, and then sprinkle the whole pond with 75 kilograms of quicklime per mu or bleach (available chlorine 32%) 30ppm to disinfect the whole pond to remove enemy pests.

3. Cultivation of bottom algae after pond cleaning and disinfection, we began to cultivate bottom algae. The method is to apply fermented chicken manure or pig manure 20kg / mu, rice bran 15kg / mu, algal auxin, microorganism, oil bran and so on. When fertilizing, you should choose a sunny day without wind, sprinkle chicken droppings evenly on the bottom of the pool, and be careful not to accumulate. Then, it is appropriate to enter 10-15 cm sea water with a specific gravity of 1.010-1.014. After 3-5 days, the bottom algae propagated gradually and formed the algal bed. Brown diatoms and tender green algae are the best in the algae bed.

4. After putting in the seedlings and cultivating the bottom algae, the seedlings can be put in. The seedlings mainly come from the natural seedlings collected in the sea area. The selection of fish fry requires complete fins, complete scales, no mechanical damage and strong vitality. The seedling density is controlled at 5000 ~ 7000 tails / mu and the specification is 200 ~ 240 tails / kg. As the catfish will not cannibalize each other of the same kind, it can be released in batches and caught big and small at harvest.

5. after nurturance management begins to put in seedlings, the water depth should be maintained at about 10 to 15 centimeters, and the water quality should be kept clear so that sunlight can be transmitted to the bottom of the pool, so as to facilitate the photosynthesis of algae and accelerate the reproduction of bottom algae. However, after a period of time, the original cultivated bottom algae will be eaten by the catfish, and the water quality will begin to become muddy. In order to meet the growth needs of the fish in the pond, the bottom of the fish should be drained and fertilized in time in order to reproduce the bottom algae and provide food for the fish. However, it is worth noting that the drainage pond should pay attention to the weather forecast, otherwise if it rains, the algae bed will be washed away. In addition, it is necessary to prevent the harm of ferocious fish, birds, crabs, conch and so on.
