Fish Feeding Culture Methods Fish Feeding Methods Summary

1, biological feed fish. Application of photosynthetic bacteria, crop straw (such as straw, rice straw, corn stalks, peanut shells, etc.) produced into fish biofeed, the production method is: first crop straw crushed, put the straw powder into the fermentation pool, add 80% of the weight of the straw powder water, 1% of the saccharification enzyme, 1% of the composite enzyme, 0.5% of the live yeast, 1% of the sodium chloride, 0.5% of the lactic acid, mix thoroughly, and then access to the 3% of the photosynthesizing bacteria, and cultivated at 15-35℃ for 2 days. The material layer is full of white mycelium issued by the flavor that is highly effective fish biofeed, can be made into particles drying storage.

2, high fertility fish. Bio-compound bacterial fertilizer "aquatic" fertilizer is a new type of non-toxic and harmless to humans and animals, it replaces ammonium carbonate fertilizer fish, can promote photosynthesis of aquatic plants, increase dissolved oxygen in the water, and fundamentally prevent the summer and autumn "flood pond" occurs. Monthly per mu only need to apply fertilizer high 0.75 kilograms, calcium superphosphate 5 kilograms, less than 20 yuan input can profit more than 100 yuan, input-output ratio of up to 1:6.2, the benefits are very significant.

3, grass powder chicken manure feeding fish. Beans, peanuts, corn, rape and other crop stalks or weeds dried and powdered, mixed with chicken manure fermented into high-quality bait, with which to feed fish can reduce the cost of about 40%. The method is: with 2.5 kg specifications of the plastic pot, the first will be into the fermentation agent, brown sugar 100 grams, and then poured into the warm water (15-30 ℃ is appropriate), until filled with the entire plastic pot, cover tightly sealed, placed 12-24 hours, that is, the mother of the fermentation; and then take 30% of the dry chicken manure, straw and grass powder 40%, rapeseed or cottonseed cake 10%, cornstarch 20% after mixing, take the mixed dry material 50 kg Then take dry chicken manure 30%, straw grass powder 40%, rapeseed cake or cottonseed cake 10%, cornstarch 20%, mix well, take 50 kg of mixed dry material, spread it on the ground, then mix 40-60 kg of water and 2.5 kg of mother liquor, pour it into the dry material and mix well. Then, the mixed material into a sealed cement pool, tanks, plastic bags and other containers, compacted, sealed airtight, 8-10 days in winter, 3-5 days in summer, there is a curved aroma, sour flavor, indicating that the fermentation is complete, you can take it to feed the fish.

4, calcium fresh phosphorus fertilizer fermentation feeding fish. Calcium-magnesium phosphate fertilizer is commonly used in fish farming fertilizer, but its characteristics are insoluble in water, and many fish farmers are calcium-magnesium phosphate fertilizer directly on the water splash pool, that is, can not quickly fertilize the water quality, but also caused a waste, if the fermentation is applied to the fish pond, the effect of fertilizer is very different. Available per 100 kilograms of fertilizer plus 200-250 kilograms of animal manure, 150 kilograms of vegetable garden fertilizer soaked mud, fully mixed, piled into a tower, the surface of the back of a shovel or a wooden board patted tightly, and finally covered with plastic film sealed, composted for 20 days, the vast majority of calcium, magnesium, and phosphorus will be dissolved into the conversion, you can open the heap of application. Every mu every 15 days 30 kg of fermented fertilizer, 3-5 days after the plankton will be a large number of breeding, pool water showing green or brown-green, the effect is very satisfactory. Under the same conditions, the application of fermented fertilizer can increase production by about 100 kilograms per acre than direct sprinkling, and reduce costs by more than 200 yuan.

5, husk compost fish. Rural areas around the rice husk resources are very rich, if you can use the husk manufacturing compost fish, both to avoid environmental pollution caused by incineration, but also opened up a new source of fish fertilizer, greatly saving bait. Fish ponds can be selected near the flat for the composting place, 500 kg of hulls, 300 kg of pig and cow dung, 100 kg of human urine and water 800 kg proportion of mixing, mixing side pile, mixing a batch of a batch of piles until the pile into a 2 m high, 5-6 m wide rectangular pile, watering, in the pile of the surface of the covered with 5-6 cm thick of fine soil or sludge sealing. Generally 5-10 days of compost can be applied to the fish pond to fertilize the water proliferation of bait, as fertilizer application of the best results.
