Green feed fish "six to do"

First, the choice of green feed varieties. At present, the most common fine green feeds are ryegrass, sudan grass, elephant grass, pine cone herb and duckweed. Different green feed has different nutritional value. In the different growth stages of fish, different fine green fodder should be selected. In the production can be selected according to the difficulty of the source of green feed and the needs of the growth and development of the fish.

Second, timely castration. Green feed contains different nutrients at different stages of growth. Grasses that are not timely castrated, often due to increased degree of lignification, result in a significant decline in the utilization of forage grasses by fish. In general, quail-type green fodder should be castrated at the time of heading, and legume-type green fodder should be castrated at the early stage of flowering. After the cut green feed is fed in a timely manner, it will take a long time to store. Not only the nutrients will be easily lost, but also the palatability will deteriorate.

Third, processing modulation. Adult fish breeding can directly feed castrated green fodder. If used for seed cultivation, green feed should be chopped or beaten. Fermentation methods can also be adopted to increase the palatability and utilization of green feed. If the peanut is poor in palatability, it cannot be digested and absorbed directly by the fish, but after fermentation, the fish can be consumed.

Fourth, strengthen the prevention and treatment of fish diseases. Green feed is mainly used by herbivorous fish, and herbivorous fish are susceptible to disease. Therefore, we should always pay attention to the disinfection of water bodies and use of baits to prevent fish diseases, and reasonably arrange the amount of feeding, feeding time and times.

Fifth, adhere to the combination of green and fine feed. Although the nutritional value of green feed is relatively comprehensive, its own concentration of nutrients is low, and it is difficult to meet the needs of rapid growth of fish. The more feasible approach is to combine green and fine feed and complement each other.

6. Make full use of the pond to cultivate green feed. When the arable land is insufficient, it is necessary to use ponds, shores, embankments and other places to grow green feed. Pond fish farming can use green ponds, ryegrass, etc. in winter ponds to achieve a combination of planting and breeding to achieve high yield, low consumption, high efficiency, and low cost.
