Feed for feeding cage-culturing abalones

Abstract

The invention discloses a feed for feeding cage-culturing abalones, comprising fish meal, soybean meal, kelp, monocalcium phosphate, brewer's yeast, undaria pinnatifida, choline chloride, spirulina, abalone premix, wheat gluten and water. The feed is prepared by crushing, mixing, stirring, pelletizing, tabletting and the like. The culture experiments prove that the feed disclosed herein can satisfy all nutritional demands of the cage culturing process of abalones, can adapt to the cage-culturing environment, and can be stable in water for 48-72h; the cultured abalones have normal and bright body color which is close to a wild body color; by using the feed, the cultured abalones grow fast, the conversion rate of the feed is high, the cultivation benefit is good, the immunity function and anti-stimulation can be obviously enhanced, the activity is good, the amount of organic residues in excrement is effectively reduced, and the water quality of the abalone culturing area is effectively improved.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to a high-efficiency compound feed for raising caged abalones that can not collapse for 2-3 days under the action of ocean currents and can ensure the feeding strength of abalones. Background technique [0002] As we all know, abalone is a traditional precious seafood in our country. It is delicious and nutritious. Lingsu has an obvious effect on inhibiting tumors, so it is not only a nutritious food but also a rare marine drug. In the past decade or so, due to the sharp decline in the output of major abalone-producing countries such as Australia, Japan, the United States, and Chile, the price in the international market has continued to rise. The market prospect is very broad. my country's artificial abalone farming industry began in the mid-1970s. After more than 30 years of development, abalone farming in Liaoning, Shandong, Fujian, Guangdong and other regions has become one of ...

Problems solved by technology

At present, the abalone growing mode of abalone is mainly the offshore floating raft hanging cage mode, which mainly feeds kelp and Gracilaria, etc. The disadvantages are monotonous nutritional components, long breeding cycle, abalone is prone to disease, etc., and is affected by kelp, etc. Due to the limitation of resources, it is more and more urgent to develop a compound feed suitable for raising abalone in cages
