Stocking density is appropriate, fertilization of fish. Hu Qihou in the pond according to the stocking of about 50-100 grams per mu of grass carp, carp 800-1000 fish fry stocking standards, so that it grows as soon as possible to gain weight. If the stocking density is too thin can not make full use of the pond water and natural bait, fish production is not high; density is too large production can be improved, but the individual listed in the pond is small, not in line with the specifications of commercial fish, sell on a good price. When stocking fish, he used 3% of the salt water immersion for 5 minutes to disinfect, cultivate robust fish. If the pond water quality is thin, when stocking fish species, can add plenty of rotting human and animal manure fertilizer, so that the water to raise fish, improve production.

Feeding a mixture of concentrate, fine feeding. Hu Qihou raised grass carp, carp and other predatory fish ponds, need to feed a lot of cornmeal, rice bran, bran, soybean cake powder, tofu dregs and other mixed concentrates and some of the young grass, plant leaves, greens and other fresh feed to ensure that the fish eat, eat well. He fed feed according to the morning, afternoon and evening 3 times. The amount of feeding in the morning and evening should be larger, and the amount of feeding at noon should be smaller. The daily input is about 2-3% of the total weight of the fish calculated, basically according to the fish rationing, scientific feeding.

Frequent refilling of new water, deep water fish. In the summer and fall seasons, the water temperature is too high, the decomposition of organic matter in the pond is accelerated, the oxygen consumption increases, the pond water is prone to lack of oxygen, deterioration, endangering the normal growth of fish. At this time, Hu Qihou every few days from the Luanhe River to introduce new water, increase the amount of dissolved oxygen in the pond water, and keep the pond water 2 meters deep or so, the water temperature control in 23-29 ℃, in order to facilitate the normal growth of fish.
