Green feed for fish has very important significance to make up for lack of concentrate feed, reduce the cost of fish farming, and improve the breeding efficiency. In the actual production, we should pay attention to the following questions.
Choose a good green feed variety. At present, the most common fine green feeds are ryegrass, sudangrass, bitter leeks, elephant grasses, pine cone herbs and duckweed. Different green fodder has different nutritional value, and different excellent green fodder should be selected during different stages of fish growth and development.
Timely castration. Green feed contains different nutrients at different stages of growth. General grasses are castrated at the time of heading; Legumes are castrated at the early stage of flowering. Secondly, the pasture after castration should be fed in a timely manner, and it should be stored for a long time. The nutrients of the pasture should be easily lost and the palatability is poor.
Processing modulation. In addition to the adult fishery that can be directly fed with castrated green fodder, if it is used for seedling cultivation, the green fodder should be chopped or beaten. Fermentation methods can also be adopted to increase the palatability and utilization of green feed. In order to adjust the remaining deficiency and ensure the constant supply of green feed, on the one hand, planting varieties can be reasonably arranged; on the other hand, it is also possible to make green hay from the green feed during the peak season.
Strengthen the prevention and treatment of fish diseases. Green fodder is mainly used by herbivorous fish, and herbivorous fishes are easy to attack. Usually, attention should be paid to the disinfection of water bodies and prevention of the use of baits, and the amount of feeding and time and frequency of feeding should be properly arranged.
Adhere to the combination of green and fine. Although the nutritional value of green feed is relatively comprehensive, but its own nutrient concentration is low, it is difficult to meet the energy and other nutrients required for rapid growth of fish. A more feasible approach is to combine green and refined, complement each other. As for the proportion of green and concentrated feed, it depends on several factors such as the production unit green, the source of concentrate, the price of concentrate feed, the degree of intensive fish farming, and the requirements for fish production.
Make full use of the pond to grow green feed. When the arable land is insufficient, it is necessary to use the edge of the pond, the bank, and the edge of the embankment. In the lakes and reservoirs, fish farming can use the winter water level drop-off area to grow green fodder. When the spring water level rises, submerged cyanine fish and fish ponds can use green manure ponds, ryegrass grasses and gardenias to achieve high yields and low costs. High efficiency, low consumption.
