Problems solved by technology

At present, the cultured geoduck is mostly fed with natural biological bait. These natural biological baits have relatively simple nutrients and may contain some harmful organisms such as bacteria and parasites, resulting in slow growth of geoduck, long growth cycle, and easy to be attacked by microorganisms. The economic benefits of breeding are low and cannot meet market demand

Abstract

The invention relates to an aquaculture feed and particularly relates to a special compound feed for a geoduck and a processing method. The formula comprises the following components: 15-25% of fish powder, 10-20% of soy protein concentrate, 20-35% of soybean meal, 3-6% of corn protein powder, 5-8% of corn starch, 1-2% of alpha-starch, 5-9% of seaweed meal, 3-5% of wheat meal, 2-3% of spiral seaweed powder, 2-4% of shell powder, 2-3% of fish oil, 2-3% of b vitamin b complex and 1-2% of compound mineral substance. The processing method comprises the following steps of: (1) weighing the raw materials; (2) mixing for the first time and roughly crushing after mixing; (3) carrying out super-fine crushing; (4) mixing and agitating for the second time; (5) heating and modulating by a modulator and curing; (6) granulating by an extruding bulking machine; (7) drying by a drying machine; (8) cooling by a cooling machine; (9) crushing by a super-fine crushing machine; and (10) packaging a finished product. The special compound feed disclosed by the invention has a scientific formula and a reasonable process; and the feed can meet nutrition needed by the growth of the geoduck, can improve thegrowing speed of the geoduck, avoids the invasion of bacteria, parasites and the like on the geoduck, and reduces the pollution to the water quality.

Description

technical field [0001] The invention relates to a feed for aquaculture, in particular to a special compound feed for geoduck and a processing method thereof. Background technique [0002] Geoduck (Panopea abrupta), also known as the elegant Poseidon clam, is a large shellfish belonging to the phylum Molluscs, the class Bivalves, the order Hyaluridae, the family Sculptidae, and the genus Poseidon. It is mainly distributed in the western coasts from Alaska to California in the United States. Since the local people do not eat geoduck, geoduck resources are abundant and grow well. However, since Asian immigrants began to prey on geoduck in North America, the local geoduck has gradually become an endangered species. Geoduck is rich in nutrition, delicious in taste and high in economic value. It is a high-grade seafood in the Far East, including Chinese and Japanese. my country imports more than 2,000 tons of geoduck from the United States, Canada and other countries every year. T...
