Plectropomus leopardus breeding feed and preparation method thereof

Abstract

The invention discloses a plectropomus leopardus breeding feed. The plectropomus leopardus breeding feed specifically comprises the following components in parts by weight: 70-100 parts of imported plain flour, 30-60 parts of starch, 300-330 parts of super red fish meal, 440-470 parts of shrimp meal, 20-50 parts of fish oil, 80-100 parts of nutrients and 4-6 parts of a natural pigment. The materials are mixed, crushed, granulated, dried, cooled and quantitatively packed. By adopting the technical scheme, a product, namely the plectropomus leopardus breeding feed, has the characteristic of redworms; the plectropomus leopardus breeding feed simulates the red worms to swim and drop in an S form in water when fed; the attractivity to fish bodies can be enhanced; moreover, the proportion of trace elements is reasonable; the immunity of fry bodies can be improved; and the disease resistance of fry is enhanced.

Description

technical field [0001] The invention relates to a preparation method of an aquatic fish feed product, in particular to a preparation method of a seedling raising feed for East Star Spot, and belongs to the field of aquatic feed processing. Background technique [0002] East star spot, a kind of fish belonging to the genus Acanthidae, is mainly distributed in the tropical regions of the Indian Ocean and the Pacific Ocean. It is distributed on the east and south coasts of Hainan, but the number is rare; East star spot is rich in nutrition, and the meat is tender, white and delicious, similar to chicken , known as "sea chicken", and it is also a low-fat, digestible, high-energy, high-protein high-quality edible fish. In addition, there are fats, calcium, phosphorus, and Iron, lysine, thiamine, riboflavin, niacin, ascorbic acid and multivitamins have always been sought after by people, and have been promoted as one of the four famous fish in Hong Kong and Macau. [0003] For ex...

Problems solved by technology

[0003] For example, the patent document with the application number CN201610938459.5 discloses the extruded and sinking compound feed for East star spot seedlings. The feed provided in this patent cannot exist in water for a long time, and the feed is dissolved in water for a short time, resulting in faster loss of nutrients. , juvenile fish cannot eat in time, resulting in slow fish growth

[0004] East star spot seedlings need to be fed with live insect bait during the feeding process. In the prior art, the Middle East star spot seedlings start to feed oyster fertilized eggs or larvae on the third day of ovulation, and start feeding unenhanced oysters when the seedlings are about 2.5 mm in size as the fish grows up. The S-type small rotifers, when the whole body of the eastern star spot seedlings is about 3.9 mm, start feeding the enhanced S-type rotifers with a similar mouth size, and when the eastern star spot seedlings are about 6 mm long, start feeding the L-type rotifers. For rotifers, when the seedlings are 9 mm long, start feeding the nauplius artemia; the method of feeding the seedlings with live insects will easily cause a large number of bacteria in the worms to enter the seedlings, resulting in a decrease in the survival rate of the seedlings
