What are the advantages of aquaculture material? The aquaculture material is based on the original pellets. It is optimized and improved to meet the nutritional and technological needs of aquatic animals. It has a higher production temperature and a larger pressure space than the pellets. Extrusion, ripening, and then into the normal air environment, the production of loose porous, relatively low density of feed, with high digestion and absorption rate, rapid growth of fish, convenient feeding and management. First, stocking mode The use of bulking materials requires a reasonable breeding model to match them, so that the advantages of aquaculture materials can be maximized. At present, the common types of waters in the two lakes and Jiangxi are Shantang Reservoir and Jingyang Pond, Shantang Reservoir high-yield model (Table 1) and Jingyangtang high-yield model (Table 2). Table 1 High-yield model of Shantang Reservoir Table 2 High-yield mode of intensive pond Second, feeding mode Considering the higher nutrient concentration of the bulking material, it is recommended to use the feeding mode of the expanded material + functional feed (664) when feeding, so as to ensure the growth of the filter-feeding fish and maintain the healthy and rapid growth of the fish. Of course, it is also possible to adopt a feeding mode of expanded material + big head fish (flower bud) material (628/928). Third, the rate of feeding Under the same nutrient concentration and feed rate, the digestion and absorption rate of the expanded material and the growth performance of the fish body are higher than that of the pellet material. According to the different specifications of fish and the digestion and absorption of different seasons, it is recommended to feed according to the feeding rate in Table 3. Fourth, feeding strategy 1, feeding time and method Xiaobian suggested that the farmer should feed 4 times a day, feeding time is 8:00, 11:00, 14:00, 17:00, and the daily feeding amount is allocated in the ratio of 2:3:3:2. The third meal can be fed functional feed (664). 2, feeding method In the previous period (3-4 months), the feeding cycle is 7-8 days, and the feeding amount is 10% of the daily feeding amount; the medium (6-8 months) feeding period is 5-6 days, and the feeding amount is daily. The feeding amount is 8%; in the later period (September-November), the feeding cycle is 7-8 days, and the feeding amount is 6% of the daily feeding amount. Calculate the current feeding rate after each feeding, and adjust accordingly according to the recommended feeding rate in Table 3 to achieve the best feeding effect. Table 3 Recommended Feeding Rate Table for Expanded Materials V. Expanding material mixing method The expanded material can be mixed well or mixed by hand using a stirring device. The specific operation is as follows: first dissolve the drug in water, and then evenly mix with the feed. Generally, 0.75 kg of water is used per 25 kg of feed to avoid low drug adsorption rate due to over-drying of the feed, or the feed is too wet and the feeder is blocked.
