With the further adjustment of the rural industrial structure, the special aquaculture industry has developed rapidly. In particular, the number of farm households raising special aquatic products is increasing. This will inevitably require a large amount of animal feed, especially fresh live bait. Therefore, the contradiction between supply and demand for bait has become increasingly prominent. Seven kinds of solutions are now provided: (1) Specialized breeding of various waste materials close to towns and cities. Professional households can use all kinds of animal internal organs and scraps in meat processing plants and fish processing plants. (2) Collecting natural baits In rivers, lakes, and ponds in the border areas, in addition to making full use of small trash fish and shrimps, it is also possible to collect snails, clams, oysters, etc., and wash them with shells, then chop and crush them as feed. In addition, leeches, Artemias, rotifers, etc. can be collected from waste water ponds in urban and rural areas. (3) Installation of black light traps Black light traps are installed on the aquaculture water to allow the cultured animals to directly ingest. (d) Breeding zooplankton is suitable for the cultivation of various rotifers, freshwater horns, and Artemia, and their protein content is 2- to 3-fold higher than that of plant foods, palatability, and digestibility. It also contains many stimuli. The active substances that grow and enhance appetite are the necessary foods for special aquatic products, especially in young age. They can use their advantages of short breeding cycle and high yield, breeding and breeding with waste ponds or culture troughs. (5) Feeding Cockroaches The “five-step method†is used to artificially feed Taiping No. 2 quail, which is a good-quality bait for special aquatic seedlings and can be used as an attractant for domesticated aquatic animals to eat artificial feed. (6) Feeding fly, fly, fly, and fly is a high-quality, high-protein animal feed, rich in vitamins and trace elements, and its digestibility and palatability are close to high-quality fish meal. The fly breeding cycle is short and the yield is high. In the large-mouth basin, casks, water tanks, etc. put livestock and poultry waste and feces as bait, attracting fly breeding. (7) Use of artificial compound feed Special aquatic products have high nutritional value and require high feed protein content and complete nutrition. Therefore, in the large-scale development of special aquaculture, the development and utilization of artificial compound feed is imperative.
