Abstract

The invention discloses a functional feed for relieving winter syndromes of fugu rubripes and belongs to the field of aquatic feed. The functional feed is based on existing fugu rubripes compound feed, and a part of wheat gluten, corn gluten meal and soy protein concentrate powder are replaced with fish meal and hydrolyzed fish protein, so that the content of protein in the fugu rubripes feed is reduced by two percentage points and is 46%; at the same time, the use amount of vegetable oil in a formula is reduced, so that the content of fat in the fugu rubripes feed is reduced by two percentagepoints and is 9%. Compared with minced trash fishes, the functional feed has the advantages that the liver antioxidant capacity is improved under the condition that the fugu rubripes have no significant differences during growth, the incidence rate of the winter syndromes is significantly reduced by 19%, and the survival rate is increased. At the same time, the feed formula also saves feed protein and fat resources, reduces the breeding cost and ensures the yield and benefit of breeding of fugu rubripes over-wintering fry.

Description

technical field [0001] The invention belongs to the technical field of compound feed for seawater fish, and in particular relates to a functional feed for coping with winter syndrome of redfin puffer. Background technique [0002] Redfin puffer (Takifugu rubripes), commonly known as river puffer, is one of the important marine species in northern my country and has high economic value. Currently, it is mainly exported to Japan and South Korea, and the product size is above 600g. The suitable water temperature for redfin puffer farming is 16-23°C, and it basically does not eat below 10°C. In northern my country, from late October or early November to April of the next year, the seawater temperature is not suitable for farming. Therefore, in order to ensure the successful farming of red-finned puffer in the north and to meet the market demand for large-scale puffer, it is necessary to transfer the hatched puffers after they have been cultured in outdoor ponds or sea cages.
