【正文】 next day with a long handle rake bottom mud and lime to make, play a role of antivirus of quick lime. Some fish pond, if unable to drain before qing tong qing pool, or the original water discharge and then can39。 Organic matter in the higher level of corruption, pollution, the serious bottom on the better the results。Second, save production costs. 飼料費(fèi)用一般約占養(yǎng)魚成本的60%以上，廣辟飼料來源，降低飼料成本，節(jié)省開支是提高養(yǎng)魚經(jīng)濟(jì)效益的關(guān)鍵。中國農(nóng)科院水產(chǎn)研究所(1995)用適當(dāng)濃度腐殖酸水溶液潑撒飼養(yǎng)對(duì)蝦水池，結(jié)果腐殖酸可有效防止銅、鉛、鎳等重金屬對(duì)魚類生長和繁殖的危害，促進(jìn)魚類生長加快。Third, adjust the density of livestock. 實(shí)行輪捕輪放和輪養(yǎng) （1）是魚類實(shí)行輪捕輪放，改變過去年底一次干塘起捕的習(xí)性，常年根據(jù)市場魚價(jià)適時(shí)起水銷售，賣個(gè)好價(jià)。Four, strengthening prevention and control of fish diseases. 近年來暴發(fā)性魚病在很大程度上制約著漁業(yè)生產(chǎn)的發(fā)展。 Species range strictly sterilized before。In recent years, explosive fish disease to a great extent, restricts the development of fishery production. Some fish at ordinary times didn39。如有的養(yǎng)殖戶同一口池塘上半年養(yǎng)南美白對(duì)蝦，下半年養(yǎng)鯉魚，既提高了經(jīng)濟(jì)效益，又減少了病害的發(fā)生，效果好，值得借鑒。Feed costs accounted for about 60% of the fish cost of above monly, wide monarch feed source, reduce feed costs, save money is the key to improving economic efficiency of fish farming. 1 to take advantage of youth generation, planting grass pond, bunds wasteland, use duckweed, ditches, such as water or collect the tender grass weeds to feed the fish, can save the concentrate. Summer can install in the fish pond 20 centimeters from the surface of the water 60watt bulb trap into the pool, and vigorously promote using cheap bread and bran etc, replace or less with the high price of fish meal, soybean meal and other ingredients, which can greatly reduce the feed cost. Practice proved in rapeseed meal, blood meal, etc as main raw materials, adding suitable amount of grease, match into the bait of vitamins, minerals, nutrients can reach the demand for fish, fish farming efficiency is better. 2 bait in the appropriate increase the vitamin C content. Vitamin C can prevent toxic residues in fish body lifting method is simple. Rapid. Accurate function sensitive to remove toxic substances. 3 add humic acid. Humic acid is farmed animals green feed additives. Chinese academy of agricultural sciences39。3添加腐植酸。而且魚類的肉質(zhì)鮮美，市場價(jià)格高。投放光合細(xì)菌要注意：多菌種混合比單菌種投喂好；有機(jī)物腐敗程度越高、污染越嚴(yán)重的池底投放效果越好；可與麥飯石、沸石等合用，效果更佳；不能與消毒劑合用，以免被殺死。生石灰清塘：在池塘修整后，選擇晴天進(jìn)行生石灰清塘，將干粉均勻干撤到塘底或池底及塘基上，再故入4－6厘米清水，次日用長柄耙將池底淤泥和石灰漿調(diào)勻，發(fā)揮生石灰的殺毒作用。 Lime can kill bacteria, increase water, oxygen, increase fertility of silt.
