Selection of green forage plant species The most common excellent green forage plants are ryegrass, sudangrass, elephantgrass, 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.
Timely cutting green feed plants in different growth stages contain different nutrients. Castor plants that are not timely castrated are often subject to a significant decrease in the utilization of forage because of increased lignification. For example, common grasses should be castrated at the time of heading, and legumes should be castrated at the early stage of flowering. After cutting, the green feed plants should be fed in a timely manner. If they are left for a long time, not only the nutrient components will easily dissipate, but also the palatability will deteriorate.
Processing cultured adult fish can be fed directly to castrated green fodder plants. 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 plants. If the peanut is poor in palatability, the fish can't directly digest it, but after fermentation, the fish can be eaten.
Strengthening the control of fish diseases Green feed plants are used primarily by herbivorous fish, and herbivorous fish are prone 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.
Although the nutrition of green and concentrated feed combined with green feed is relatively comprehensive, the concentration of nutrients is low and it is difficult to meet the need for rapid growth of fish. The more feasible approach is to combine green and fine feed and complement each other.
Make full use of the pond to cultivate green fodder plants When arable land is insufficient, use ponds, banks, banks, etc. to grow green feed plants. Pond fish farming can use green ponds, ryegrass, etc. to achieve a combination of planting and breeding to achieve high yield, low consumption, and high efficiency.
