High-intensity water-resistant long-storage-period gelatinous artificial aquatic feed

Abstract

The invention provides a high-intensity water-resistant long-storage-period gelatinous artificial aquatic feed. The high-intensity water-resistant long-storage-period gelatinous artificial aquatic feed is prepared through the following steps of: adding dry powder substances such as dry powder raw materials, feed additives, which are superfinely ground to fineness being more than 100 meshes, to mixed liquid containing liquid fish proteins, fresh chlorella slurry, biological preservation solutions, garlic juice, and the like; stirring, heating to 50-55 DEG C at the same time, and then stopping heating and continuously stirring, and sufficiently soaking the dry powder substances; then adding a hot agar solution with temperature of 90-95 DEG C, and continuously stirring for 5-10 minutes; then filling into a packaging barrel when the solution is still hot, and cooling to room temperature to obtain the gelatinous feed; and covering and sealing the packaging barrel with a barrel cover so that the gelatinous feed is stored and transported conveniently. The high-intensity water-resistant storage-resistant gelatinous artificial aquatic feed provided by the invention is cut into strip blocks with different specifications to be fed according to the individual sizes of cultured objects by using a screen mesh of different meshes as a cutting tool when in use.

Description

technical field [0001] The invention relates to a high-strength, water-resistant and storage-resistant gel-like aquatic feed suitable for raising aquatic animals such as abalone and conch (shellfish). Background technique [0002] At present, the known industrialized production of aquatic feed commodities for raising aquatic animals such as abalone and conch (shellfish) generally only has two kinds of hard flakes and powders, and dry feeds with a water content of less than 12% have not yet been produced. The factory mass-produces high-strength, water-resistant and storage-resistant gel-like artificial aquatic feed products with a water content greater than 50%. Although artificial aquatic dry feed has many advantages, it is not ideal for abalone and conch (shellfish) and cannot be completely replaced. Natural bait, especially not suitable for raising in cages at sea, the main disadvantages are: 1. In order to have a long-term shape-keeping effect in the hard flake feed and p...

[0002] At present, the known industrialized production of aquatic feed commodities for raising aquatic animals such as abalone and conch (shellfish) generally only has two kinds of hard flakes and powders, and dry feeds with a water content of less than 12% have not yet been produced. The factory mass-produces high-strength, water-resistant and storage-resistant gel-like artificial aquatic feed products with a water content greater than 50%. Although artificial aquatic dry feed has many advantages, it is not ideal for abalone and conch (shellfish) and cannot be completely replaced. Natural bait, especially not suitable for raising in cages at sea, the main disadvantages are: 1. In order to have a long-term shape-keeping effect in the hard flake feed and powder feed, more gelatinized starch has to be added to the feed Once these feeds are not ingested in time after being fed, the gelatinized starch and binders in the crumbled and decayed feed residues will stick to the bottom and walls of the cages, blocking the gaps in the cages and causing It destroys the permeability of the hanging cage and hinders the water exchange inside and outside the hanging cage, thus affecting the growth of aquatic animals such as abalone and conch (shellfish) raised in the hanging cage. It takes time and effort to wash and remove the cage, which is very troublesome; two, the hard flake feed and powdered feed contain animal protein nutritional components, although the dry feed can be stored for a long time below the moisture content of 12%, but it will disappear after soaking in water. It will quickly deteriorate and rot, so the feeding interval cannot be long, and the interval between feeding is about 2 days at most in summer. Therefore, at present, the majority of farmers mainly use natural bait such as kelp, wakame, and Gracilaria to raise abalone or conch (shellfish). ) category, the interval between feeding such natural baits can be as long as 4 to 5 days, and the gaps in the hanging cages are not easy to be closed, because the breeding cycle of aquatic animals such as abalone and conch (shellfish) is long, and the growth of natural seaweed, Harvesting is limited by seasons and climates, which has become a bottleneck restricting large-scale farming of abalone and conch (shellfish)
