Meal frog land intermittent culture technology
Due to the conventional cement pond culture method and large infrastructure investment, which limits the development of rural aquaculture industry, our farmland aquatic product company frog breeding has summarized a set of earth frog intermittent breeding frog technology, which is very suitable for the majority of farmers, and is described below.
Construction of commercial frog pool:
1. Location selection : The location of the breeding pond is water source, no pollution, the environment is relatively quiet, and the north wind is blocked in winter.
2. Construction method : In the paddy field or on the idle ground, the pool should be excavated according to the 1000 square meters breeding pond. The pool should be digging 600~700 square meters. The depth of the pool is about 1 meter, and the slope of the pool is about 1.3, which is convenient for the frog to land. The remaining 300~400 square meters of fruit trees, vegetables or ponds are surrounded by nylon cloth or plastic screen cloth with a width of about 1.5 meters, buried 20 cm below the ground, preventing frogs from fleeing and rats and snakes invading the frogs. . After the pool is repaired, disinfection is carried out with 150 kg of quicklime per 1000 square meters, and the frog can be released after 5 days.
If you use the pond, dam, and ditch to raise frogs, as long as you do well in the anti-escape facilities, leave empty space next to the pool, eliminate the sundries in the pool, kill rats and snakes, and raise the frog after disinfection.
Construction of a frog pool and spawning pool:
If the number of breeding frogs is large, they can be cultured by commercial frog ponds. If the number is small, the breeding frog pool can be built according to the number of breeding frogs per square meter, but the minimum should be more than 10 square meters. . During the breeding season, the frogs are allowed to lay eggs in the breeding pond. Due to the large number of species of frogs and frequent activities, it is easy to crash the egg into the bottom of the water, causing death due to lack of oxygen. Therefore, it is necessary to insist on patching the pool several times a day, discovering the egg mass and immediately picking up the eggs. Place in the incubator.
Nylon cloth with cage hatching is used to make a boat-shaped cage with a length of 2 meters and a width of 1 meter. It is placed in a commercial frog pool. The cage is filled with water 30~40 cm. The surrounding area is fixed with bamboo poles. The top of the box is set with bamboo mat or straw curtain. The shade shed is protected from the sun and the rain. The floating grass is placed in the box, and the harvested egg pieces are enlarged into the water grass for hatching. Each square meter can be 6,000 eggs, and each box has 1 to 2 nests of eggs on the same day. At a moderate temperature, cockroaches can be hatched in 2 to 3 days, and the hatching rate is as high as 80% to 90%.
èŒèšªCultivation The newly hatched cockroaches can be kept in the hatching cage or they can be moved into the sputum cultivation cage (the cage method is the same as the incubator). The depth of the cage water inlet is required to be more than 50 cm to facilitate the movement of the raft. There are 1~2 feeding bowls in each cage, and the basin should be submerged 10cm underwater for easy feeding.èŒèšª just hatched for 4 to 5 days to rely on yolk sac nutrition life, no need to feed. Afterwards, the cooked egg yolk is fed, and one yolk is mixed with one yolk to make a slurry. It can be combined with raw soy milk, bean dregs, pig blood, etc., and can also be fed with artificial compound feed. As the cockroach grows up, it should be gradually binned to reduce the stocking density. After 1 to 2 months, you can put it in a commodity frog pond, and you can stock up to 10,000 tails per 10 square meters of water.
Disease prevention:
Due to the artificial creation of a amphibious environment, frogs are generally less susceptible to illness. Common frog diseases mainly include gastroenteritis, red leg disease, and rotten skin disease. Prevention and treatment method: daily remove the bait of the table, often wash the table, alternately use quicklime, strong chlorine and other disinfection, can also be used for bleaching *** 1 g / square meter, disinfection every 10 days. Trauma drugs include erythromycin, chlortetracycline and sulfonamide. It is found that the diseased frog should be removed from the isolation treatment in time. If the diseased dead frog should be removed immediately, it should be removed.
Feed Additives are divided into microbial feed additives and Chinese herbal feed additives. Among them, microbial feed additive is a kind of microbial products that replace or balance one or more strains in animal ecosystem. In a narrow sense, it is a kind of microbial products that can stimulate the reproduction and growth of beneficial bacteria while resisting the growth of harmful bacteria. Microbial feed additives containing a large amount of beneficial bacteria (active lactobacillus, bifidobacterium, bacillus), compound enzyme, chelating peptide, mildew remover, etc., as the inside of livestock and poultry feed, can rapid reproduction, on the one hand, in bacterial metabolites and gut endotoxin inhibits the growth of other harmful flora, on the other hand, it formed the normal microbial flora in the host, Synthesize the main vitamins for the host, provide nutrition and prevent the invasion of pathogenic bacteria.
There are many different feed additives in category. There are vitamins, amino acides, antibiotics, Trace elements,Buffer feed, flavor agents, Hormonal additives, herbal additives etc.
