Abstract

The invention discloses a compound feed for fishing and a preparation technology of the compound feed. The compound feed for fishing comprises a composite compound feed and a layer of slow release membrane sprayed outside the composite compound feed, wherein the thickness of the slow release membrane is 0.3-0.5mm, and emulsion for spraying to form the slow release membrane comprises the followingcomponents by mass of 10.5-11.2% of nanometer calcium carbonate, 8.3-8.6% of lactose, 6.0-6.3% of carboxymethyl cellulose, 6.6-7.0% of polyvinyl alcohol, 5.2-5.5% of polyacrylic acid, 3.2-3.4% of polyacrylamide hydrochloride, 1.3-1.5% of sodium dodecylbenzenesulfonate, 0.3-0.5% of vitamin C, 1.3-1.5% of polyethylene glycol and 10.2-10.5% of ethanol. The emulsion has the advantage of prolonging thetime of disintegrating an effective feed.

Description

technical field [0001] The invention relates to a fish compound feed and a preparation process thereof. Background technique [0002] Fish feed is the basic substance or input of aquaculture.
