Aquaculture feed feeding technique

Abstract

The invention relates to an aquaculture feed feeding technique which is characterized in that when fish fingerlings are bred, bean cakes, peanut cakes, wheat bran, bran, silkworm chrysalis, fish meals and the like are fed, and the feeding rate is about 3%. After the fish fingerlings are bred for 15-30 days and grow to certain specifications, full rate artificial particle feeds are fed, and the feeding rate is 1-1.5%. Feeds are fed through automatic feeding machines. One to two automatic feeding machines are arranged on each pond, feeds are fed once every day, feeding time is from 9 o'clock to 14 o'clock, the speed of spraying particle feeds of the feeding machines is controlled, feeds are fed discontinuously, and the range of feeding feeds is enlarged as possible. The aquaculture feed feeding technique improves utilization rate of feeds, reduces feed cost, improves growth speed of pond fishes, guarantees water quality of ponds and improves pond yield and economic benefits.

Description

Technical field: [0001] The invention relates to a high-efficiency scientific feed feeding technology for aquaculture, which belongs to the technical field of aquaculture. technical background: [0002] my country's aquaculture industry has a long history and is the earliest country in the world to start fish farming. It has a high level of farming technology and rich experience, and is world-renowned. As early as 460 BC (Spring and Autumn Period and Warring States Period), Fan Li’s "Fish Culture Classic" (the earliest fish culture book in the world) described in detail the conditions and methods of pond culture. Since the founding of the People's Republic of China, with the optimization of the nutritional structure of food and the continuous improvement of the proportion of protein, the aquaculture industry has been paid attention to, and the breeding technology has also reached a new level. Many scientific and technological achievements have been made in the application of...

Problems solved by technology

In this feeding method, it usually causes or a lot of feed sinks to the bottom of the pond before the fish have time to eat, and after sinking to the bottom, most of them are often no longer eaten by the fish, resulting in waste of feed and increased breeding costs. Pollution of water quality; or small and weak fish cannot eat feed, which affects the growth and production of fish and the specifications of commercial fish
