Description

technical field [0001] The invention relates to a feed, in particular to a compound feed for Penaeus vannamei with humic acid as an organic disease-resistant additive component. Background technique [0002] Penaeus vannamei [Penaeusu (Lito penaeus) vannamei Boone, 1931] has good meat quality and delicious taste, high survival rate of shrimp seedlings, fast growth rate, and high meat yield. It is suitable for breeding in brackish waters and is the world's largest farmed shrimp production. One of the three types. Since the late 1990s, Penaeus vannamei has gradually become the largest prawn variety in my country. According to statistics, the output of Penaeus vannamei accounts for more than 90% of the total production of Penaeus vannamei in my country in recent years. With the expansion of breeding scale, the feed industry of Penaeus vannamei has also been developed rapidly, and there are many types of feed. However, due to the low utilization rate of feed, the nitrogen and ...

Problems solved by technology

However, due to the low utilization rate of feed, the nitrogen and phosphorus excreted into the aquaculture water are high, and a large proportion of heavy metal elements in the feed, such as iron, copper, zinc, manganese, cobalt, etc., are also excreted into the aquaculture water, resulting in serious water pollution. However, eutrophication, especially high-density farming, due to too one-sided pursuit of production, deteriorates the water body and the surrounding environment, and frequent outbreaks of shrimp diseases, resulting in a vicious cycle of more shrimp diseases, more drugs, and environmental damage, which seriously threatens shrimp farming. sustainable development of the industry

Because research institutes and feed manufacturers are not systematic enough to develop feeds that enhance the disease resistance of prawns and ensure the safety of farmed products, the current prawn feeds are not disease-resistant feeds.

[0003] Studies have shown that humic acid is a macromolecular organic compound that can improve the water quality of prawn breeding water, enhance the immunity and disease resistance of prawns, reduce diseases, reduce medication, and enhance the stress resistance of prawns. It is worth popularizing and applying. As a fertilizer, humic acid can improve the control of crop diseases and insect pests, improve soil, and improve agricultural products. There are many reports and experiences. However, the basic framework for using its formula as shrimp feed has not been established so far, which has become an obstacle to popularization and application. This is important for establishing a scientific development concept and maintaining Bad for sustainable development of shrimp farming industry
