Abstract

The invention relates to the field of aquaculture and particularly relates to a juvenile abalone microcapsule feed and a preparation method thereof. According to the invention, the microcapsule technology is applied to the juvenile abalone feed to provide juvenile abalone bait with balanced nutrient, suitable particle size, good palatability, digestion and absorption and high water stability. The juvenile abalone microcapsule feed comprises a core material, a wall material and a surfactant, wherein the core material comprises spirulina, fish meal, kelp powder and calcium propionate, the wall material comprises starch sodium octenylsuccinate and water, and the surfactant comprises span 80 and Twain 80. According to the juvenile abalone microcapsule feed provided by the invention, the proper core material and wall material are selected to generate no uncertain reaction in a matching process, the prepared feed has the characteristics of balanced nutrient, suitable particle size, good palatability, high digestion and absorption and high water stability, thereby meeting the requirements of juvenile abalone bait in abalone seedling production.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an immature abalone microcapsule feed and a preparation method thereof. Background technique [0002] Abalone is the first of the eight treasures of seafood and is of high value. Coupled with the "bao culture" with Chinese characteristics as a foreshadowing, the market for abalone products is broad. The breeding cycle of abalone is longer than that of other economic shellfish. The growth of natural bait benthic microalgae and macroalgae is limited by seasons, which has become a key factor restricting the large-scale abalone farming. This prompts people to develop abalone compound feed and effectively solve the shortage of natural bait , shorten the breeding cycle, and meet the needs of land-based intensive abalone farming. [0003] There are two forms of abalone compound feed in my country, one is powder feed, which is mainly used to feed young and young abalone; the other is sinking...
