First, a reasonable change of water, cultivation of fertilizer. From May onwards, every month or 20 days, we must use "bait" and "liquid medicine" to prevent and treat pests and diseases once. During the transitional period of summer and autumn, we must pay more attention to the adjustment of water quality; prevent pool water from becoming “turning†or becoming “oldâ€, and maintaining a proper transparency of fertilizer and water. The transparency of the fish pond is maintained at about 25 cm, between 30 and 36 cm in the shrimp pond and 35 to 40 cm in the crab pond. If the transparency of the pool water is less than the normal need of fish, shrimp and crab, use 5 to 7.5 kg of lime per acre in a timely manner to adjust the water quality, and apply fertilizer fertilizer and water as appropriate to the growth needs of fish, shrimp and crab.
Second, a reasonable feeding, promote long fat. After the beginning of autumn, fish, shrimps and crabs should be fed with bait to increase their quality and increase their quantity. Feeding of fish is 5 to 6 percent of the total fish; shrimp is fed 7 to 8 percent of the total shrimp; fresh protein feed is 60 percent of feed; crabs are fed on crabs on a daily basis. 10% of the total amount, protein feeds accounted for 65 percent of feed; carp feed was about 6 percent of total carp, and protein feeds accounted for 100 percent of feed 60. Feeding amounts of farmed fish, shrimp, and crab from October to November decreased with the gradual decrease of temperature and water temperature. Daily feeding amounts were 3% of fish, 4% of shrimp, and 4 to 5 percent of crab. About 4 percent of trout.
Third, the rational use of drugs to prevent disease (worm) damage. Every 20 days after the beginning of the fall, chlorine dioxide and other non-hazardous drugs are used. The whole pool is splashed once (in case of shrimps and crabs, sick ponds use 200 grams per acre, once a day for 3 to 4 consecutive days as a course of treatment); In addition to adding "removing nutrients", "calcium tablets", "terracilin" and other drugs to feed bait, once a month, each time the proportion of the amount of food is about 0.5 parts per thousand. Every morning and evening, we must insist on observing the situation of eating and drinking in the patrol pond and decide on the number of feeding on the next day. At the same time, we must do the “two defenses†work of preventing theft, preventing flight, and preventing predators.
