Daily management: you can choose small miscellaneous fish and shrimp for feeding, or you can buy chilled fish and pellet feed for feeding, domesticate newly stocked fry, and rationally prepare feed according to the growth stage to achieve timing, quantification, positioning and quality determination.
First, stocking density
1, the first seed should be strong and undamaged, with the same size, and the time should be selected from May to June every year. Generally, the body length is more than 6 cm per mu 1200- 1500, and the body length is more than 800- 1000.
2. At the same time, some other fish can also eat the residual bait to adjust the water quality, such as silver carp, bighead carp and white crucian carp. , but you can't mix the fierce fish such as snakehead and mandarin fish. When they go down to the pond, they should be bathed in 80 grams of formalin or 3% salt solution for 5- 10 minutes to kill parasites and viruses.
Second, the daily management
1, the supply of feed is very important. You can use small miscellaneous fish or shrimp from reservoirs, rivers and lakes as the feed for California bass, or you can go to the market to buy chilled fish or artificially feed with granular feed, but you must ensure that the feed supply is sufficient.
2. After large-scale stocking, it is necessary to stop eating for about 2 days, because California bass is unfamiliar with the new environment and needs a certain adaptation time. The newly stocked California bass will not come to eat immediately, and it is usually tamed from the fourth day.
3. When taming food, mix the broken fish pieces with water evenly, then sprinkle them evenly in the water, constantly sprinkle them to make the water feel fluctuating, and then throw the bait into the water. At this time, the fish will come for food, and they can be domesticated in 5-7 days.
4. Feed small miscellaneous fish or chilled fish to be palatable. When feeding young fish, you need to cut them into small pieces with a width of 0.5 cm. In the future, with the growth of the fish, the amount of bait blocks will gradually increase, so there will be a step-by-step process to make the fish better adapt.
5. The content of protein in feed should be 45-50%, and the ratio of plant protein to animal protein should be 65,438+0: 65,438+0.5-2. Feed other live bait such as small fry or water worms every 2-3 hours every day, and slowly mix in broken fish pieces or pellet feed, about 4 times a day, and then reduce it to 1 time in the morning and afternoon respectively.
6. Feeding should be timed, quantified, positioned and determined according to the actual situation such as weather, water temperature and fish feeding. The feeding amount of fish pieces is generally 8- 10% of the fish weight, and the pellet feed is 5-6% of the fish weight.
