Raising ducks in fish ponds can reduce the cost of farming. Fish ponds can raise fish. Above the ponds are ducks. This reduces the scope of space and greatly reduces the cost of investment. Now many farmers have begun such a polyculture. Mainly for you to introduce how to polyculture ducks in fish ponds.
1. Fish and duck polyculture. That is, a duck shed is built on the dike of the fishing pond, and a part of the pool pond is used as a playground to store the ducks directly on the fishing pond. In this way, the ecological effects of symbiosis and mutual benefit between fish and ducks can be brought into full play. Farmers can choose the appropriate mode of operation according to local conditions and can maximize their effectiveness.
2. Make a reasonable match. Duck ponds generally use 100 to 150 ducks per 667 square meters. If more than 200 ducks are to be fed, fish-feeding and omnivorous fishes, such as eel, cockroach, tilapia, or pupa, cockroach, etc., should be dominant, and grasses, cockroaches, or herrings should not be used. In addition, we must pay attention to changing water and oxygen. The number of ducks per 667 m2 of fish ponds should not exceed 250, otherwise fish production will decline significantly. With an annual output of 40-50 kilograms per duck, the duck pond will be increased by 4,800-7,500 kilograms per 667 square meters compared to non-duck, effectively fertilize the pond water, and reproduce a large number of plankton, which will grow barramundi and mackerel. Provide enough feed. Duck ponds can be bred, squid-based, per 667 square meters can be put 50 ~ 75 kg of fish, 1000 ~ 1500 tail. In order to raise grasses and herrings, 75 to 1500 kilograms and 1,000 to 1,500 tails of fish are put on every 6,667 square meters. Well-fed, 667 square meters, net fish production up to 400 kilograms or more.
3. Strengthen feeding management. In order to facilitate the management of the duck cluster, a part of the fishing pond can be used as a duck activity pool by using old mesh, screens, and other materials. It is better to raise 2 to 4 ducks per square meter of water. The mesh height is 40 to 50 on the surface of the water. Centimeters so that the fish can come in and out freely. Every morning and evening, ducks are fed at the Ikeji event venue. After the ducks enter the shed in the early evening, the duck droppings and residual food are swept into the pool. In the morning, the ducks were released from the shed and the duck droppings in the shed were swept into the pool after the eggs were quailed. In summer, the ducks have a large amount of dejecta and the water quality is too fat. It is necessary to add new water and reduce the amount of fertilizer.
Summary: Although the mixed fish can reduce the cost, it is the water quality problem to raise the ducks in the fish pond. When the ducks on the water can not avoid the duck dung, but do not change the water to the fish pond, it will easily lead to the fish ponds. Fish have diseases caused by unclean water.
Vaccine For Prevention Of Rabies
Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals
