In recent years, the price of aquatic feed has continued to rise. From 2011 to 2014, the price of conventional fish feed has increased by 600-800 yuan/ton, and the feed input has accounted for about 70% of the aquaculture cost. How to scientifically use feed to maximize feed efficiency has become aquaculture The key to good breeding results.
First, develop the most suitable rate of feeding
Scientific feeding is the key to reduce the feed coefficient and the cost of drugs. The feed rate of 25-30,250 g of grass carp and 150 g of carp should be controlled at about 2.0-2.3%, and it should also be based on different weather, water quality, and fish body. Health status, timely adjustment of feed rate, feeding process, management personnel should always pay attention to observation, when the fish do not feed on the feeding can stop feeding.
Second, water and algae, cultivate natural food
Grass carp and carp seedlings will also feed on plankton while ingesting artificial feed. During the pond aquaculture process, water quality is intensively cultivated. Microbial preparations can effectively reduce ammonia nitrogen and nitrite, while nitrogen, phosphorus and other nutrients can be converted into The algae absorb and utilize, provide the fish the natural bait, at the same time for the flower white pupae to ingest, the high yield pond pond pistachio output can reach 800 catties, the output value is 2000 Yuan.
Third, choose to regulate the feed production company products
As feed prices continue to rise and remain high, many farmers have switched to the use of some “small plants†with cheap feed products. The products are not stable and the quality is not guaranteed. Instead, feed costs are increased. Therefore, feed products for well-known companies should be selected. .
Fourth, grass breeding fish, reduce grass carp feed
Planting green grass feed such as sudan grass and ryegrass, each 30 kilograms can grow a pound of grass carp, use Tangtou and Chichi, according to the season, plant different varieties of green fodder, can feed with green feed all year round, reduce grass carp feed input, and vote for Feeding green feed 1 h before feeding artificial food, it is important to note that the green feed that has not been ingested is unloaded every evening.
Through the control of the above-mentioned key points, it can effectively reduce the input of feed costs and improve the breeding efficiency.
Multi Span Plastic Film Greenhouse
Arch greenhouse is a kind of economical greenhouse, which is welcomed by the users with graceful curve form and low cost. It has beautiful appearance, fluent visual, reasonable structure and good performance for keep temperature. It is economical greenhouse because of its relatively low manufacturing cost. It can be applied in most areas of China. Double membrane greenhouse is used more in north of China, while single film greenhouse is used more in southern region. It can get maximum sunlight when visible light is within the scope of 0.4 to 0.7 microns and form a thick envelope, which can effectively prevent heat loss and prevent the invasion of cold air. Adopting a double membrane can greatly improve heat preservation performance of the greenhouse and save operating cost. The top cover material is polyethylene lifelong anti-fog and anti-dipping film po-covering. The outer of it has the function of UV protection and the inner has the function of preventing from the sets of dew. According to the needs of customers, the sides of the greenhouse can be covered with polyethylene lifelong anti-fog and anti-dripping po-covering or polycarbonate hollow plate.
