Can farmed fish be mowed in the morning?

Cultured fish can be cut and eaten in the morning.

Fish are omnivores. Fish eating grass tastes delicious.

Feed the fish with straw pulp. Pay attention to production

Water hyacinth, Eichhornia crassipes and other aquatic forage grass are crushed into pulp, which is a high-quality feed for cultivating fry and feeding adult fish, but the following four points should be grasped when pulping and feeding fish:

(1) refined pulp. All kinds of aquatic plants should be washed with clean water, disinfected with 3% ~ 4% salt and then treated with pulverizer. Pay attention to less times and more times when feeding, coordinate the ratio of grass to water, and beat the straw pulp as fine as possible to increase the suspension time of straw pulp particles in water and increase the chance of fish feeding. Pay attention to keep the blade sharp and the speed of the machine, ensure the quality of pulping every time, and improve the utilization rate of fresh grass.

(2) Clever feeding. The feeding amount of straw pulp should be flexibly controlled according to the species, quantity and water quality of fish in the pond. It is advisable to feed 50-70 kg adult fish with straw pulp every day per mu of water surface; When raising seedlings, when the fry enter tang qian, straw pulp 100~ 150 kg is used as base fertilizer per mu of water surface to cultivate bait organisms in the water; After the fry enter the pond, feed 50 ~ 100 kg per mu of water surface every day, or feed 120 ~ 150 kg every 1 time every 2 ~ 3 days, and raise/kloc-0. In order to make the fish full, the fish should be spread evenly in the whole pond, and fed 1 time at 8-9 am and 2-3 pm every day to increase the chances of feeding the fish.

(3) control water quality. Feeding straw pulp is easy to pollute the pool water, so fresh water must be added frequently to adjust the water quality. Proper spraying of quicklime water during culture can not only sterilize and prevent diseases, but also neutralize acidic substances produced by straw pulp decomposition, which is beneficial to the formation of bacterial flocs and the growth of plankton and improve fish yield.

(4) Clever collocation. In the late stage of herbivorous and omnivorous fish culture or in adult fish culture, it is necessary to avoid feeding straw pulp alone and mix with concentrated feed appropriately (the ratio of straw pulp to concentrated feed is 5: 1 ~ 8: 1). When water peanuts are used for fish pulping, because water peanuts contain saponin toxins, salt accounting for 2% ~ 5% of the grass weight should be added to the straw pulp for disinfection. Feed the straw pulp in time after it is ready, and don't leave it for too long, so as to avoid pollution and cause fish to get sick.
