Grass carp breeding method

Abstract

The invention discloses a grass carp breeding method comprising the following steps of (1) pond preparation, (2) pond cleaning, (3) fish fingering stocking, (4) fodder feeding, (5) water quality management and (6) disease and insect prevention. One month after the grass carp is placed into the pond, the grass carp is mainly fed by pellet fodder; the protein content of fodder remains 28% to 32%; and then green forage is fed for auxiliary forage. The fodder feed applies to principles of " rough for primary period and fine for final period" and " four fixed time and four checks". Grass carp physique can be enhanced, diseases can be reduced and quick growth of the grass carp can be 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...

[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 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
