Pellet feed for tongue sole juvenile fishes and preparation method of pellet feed

Abstract

The invention discloses a pellet feed for tongue sole juvenile fishes and a preparation method of the pellet feed. The pellet feed is prepared from the following components in parts by weight: 40-55 parts of animal nutrient, 15-30 parts of plant nutrient, 5-10 parts of Chinese herbal medicine, 1-5 parts of vitamin, 1-5 parts of trace elements, 2-5 parts of lentinan, 2-5 parts of propolis, 1-5 parts of bifidobacterium, 5-10 parts of marine yeast, 2-5 parts of stachyose, 5-10 parts of photosynthetic bacterium, 1-5 parts of beer yeast, 2-5 parts of dextran, 1-5 parts of L-lysine and 1-5 parts of methionine. The pellet feed is capable of increasing the survival rate and the growth rate of the tongue sole juvenile fishes, improving the disease resistance and the feed transformation efficiency of the tongue sole juvenile fishes and lowering the feed cost in the culture process.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a pellet feed for juvenile tongue sole and a preparation method thereof. Background technique [0002] Semi-smooth tongue sole is a cultured species of flounder flounder that has been developed in my country in recent years. As a precious species in marine fish, it is loved by consumers because of its delicious taste, rich in unsaturated fatty acids, tender muscles, smooth taste, and high vitamin content. However, due to the large difference between the male and female individuals of S. half-smooth tongue sole, the small number of males and the weak reproductive ability, the reproductive ability of wild populations is weak, and there are few individuals of S. half-smooth tongue sole in nature. [0003] Semi-smooth tongue sole is a benthic fish with a wide range of food habits and low food levels. The semi-smooth tongue sole feeds by swallowing, and cannot bite large foo...

Problems solved by technology

[0004] In the current breeding process of tongue sole juveniles, general-purpose seawater fish feed is generally used for breeding, without considering the unique feeding and nutritional characteristics of tongue sole, resulting in that the feed cannot effectively meet the physiological and nutritional needs of tongue sole juveniles. It not only causes the waste of feed raw materials, but also makes the breeding cycle of tongue sole longer, and the breeding efficiency is low
