Breeding method for grass carps

Abstract

The invention discloses a breeding method for grass carps. The method comprises the steps of 1, pond demands; 2, pond preparation; 3, fry stocking; 4, feeding with feed, wherein one month after fry ofthe grass carps are put into a pond, pellet feed are main feed for feeding, the protein content of the feed is 28-32%, and with assistance of green feed, feeding with feed accords with the principleof feeding with rough feed at first and feeding with fine feed at last and the principle of four-aspect determination and four-aspect observation; 5, water quality management; 6, prevention and control of diseases. According to the breeding method, the physique of the grass craps is improved, the diseases of the grass carps are reduced, and quick growth of the grass carps is promoted.

Description

technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a method for raising grass carp. Background technique [0002] In the breeding process of aquatic products such as fish, the usual practice is to add artificial feeding bait, thereby ignoring the natural bait existing in the pond. The phytoplankton and zooplankton existing in the pond are the natural bait of fish, which can promote grass carp However, for large-scale fish farming, naturally growing zooplankton and phytoplankton obviously cannot meet the needs of grass carp farming. There are also Chinese herbal medicines mixed with soy milk to feed grass carp in the market to enhance the physique of grass carp. This grass carp feeding method The cost is too high for large-scale and common grass carp, and it is only suitable for family workshop fish farming or rare and valuable fish species. In addition, in o...

There are also Chinese herbal medicines mixed with soy milk to feed grass carp in the market to enhance the physique of grass carp. This grass carp feeding method The cost is too high for large-scale and common grass carp, and it is only suitable for family workshop fish farming or rare and valuable fish species. In addition, in order to promote the rapid growth of grass carp, fish feed containing hormones has appeared on the market. Compared with Chinese herbal medicine mixed with soybean milk, the cost of fish feed is relatively low, but after the grass carp grows, the meat quality is poor and the nutritional value is low, which is not conducive to the health of the eaters
