Description

Technical field [0001] The present invention relates to the field of fish feed, in particular to a floating puffed compound feed for bamboo shell fish. Background technique [0002] Bamboo shell fish is a famous and high-quality aquaculture species in my country with high economic value and short supply in domestic and foreign markets, especially in Malaysia, Thailand, Singapore, Taiwan and other places. It can be cultivated as an important species for exporting foreign exchange. At present, Guangdong Province is the main production area for cultivating bamboo shell fish. There are three main types of bamboo shell fish in Guangdong: one is Thai bamboo shell fish (scientific name: Yunbanjiantang Channa), and the other is Australian bamboo shell fish (scientific name: line Wenjian pond snakehead), the third is hybrid bamboo shell fish (the first hybrid of Thai bamboo shell fish and Australian bamboo shell fish). [0003] At present, the culture mode of bamboo shell fish mainly adopt...

Problems solved by technology

The disadvantages of this feeding method are as follows: ①The chilled fish itself contains a large number of germs and parasites (including spores), which indirectly become pathogenic carriers. Feeding a large amount of fish will easily lead to infection and disease of the bamboo shoot shell fish; ②The chilled fish itself is nutritious. Not comprehensive, lack of minerals, vitamins and other trace elements, long-term feeding will cause malnutrition, liver and gallbladder damage of bamboo shoot shell fish, and cause syndrome; ; ④ Chilled fish paste has poor adhesion and dissolves when it meets water. Due to seasonal restrictions, cold storage is also required, which consumes electricity and increases costs

Another part of farmers feed live baits such as red worms and dace larvae. However, the supply of live bait is often insufficient, and the quantity is difficult to control, which leads to serious carnage of bamboo shoot shell fish and reduces the survival rate. Especially in winter, dace larvae are in short supply. Seriously restricting the sustainable development of bamboo shoot shell fish farming
