Abstract

The invention relates to a black fish expansion compound feed, and is specifically suitable for a new species of No. 1 Hang Channa. The black fish expansion compound feed is a mixture prepared from various raw materials by an expansion granulated feed processing method, and comprises the following raw materials in part by weight: 30 to 50 parts of fish meal, 20 to 40 parts of soya bean meal, 15 to 25 parts of flour, 2 to 10 parts of meat and bone meal, 2 to 4 parts of soybean oil or fish oil, 1 to 2 parts of calcium biphosphate, 0.8 to 1 part of sylvite, 0.8 to 1 part of sodium salt, 0.8 to 1 part of multivitamins, and 0.5 to 1 part of squid paste. The invention has the advantages that: the feed is prepared by finely selecting high-quality raw materials according to a scientific formula and the requirement of each growth stage of the No.1 Hang Channa, has high stability in water, comprehensive nutrition, high attractant performance, and high digestive absorption performance, and can meet the requirement of No. 1 Hang Channa for nutrition, improve bait efficiency, reduce breeding cost, and reduce breeding water body pollution and water change amount.

Description

technical field [0001] The invention relates to the field of fish feed, and mainly relates to an extruded compound feed for black fish. Background technique [0002] "Hangna No. 1" is a new species of snakehead cultivated by the Yuhang Blackfish Research Institute. It is a hybrid of a male snakehead native to Yunhe Town (the scientific name for snakehead) and a female snakehead from Guangzhou. From the appearance point of view, the difference between "Hangju No. 1" and the local blackfish in Yunhe Town is that the scales of "Hangjun No. 1" are distributed in the shape of "eight" from the head to the tail, while the scale pattern of traditional snakehead is mostly a "one". The font and two "eight" fonts are arranged alternately. After artificial domestication, this species can completely ingest artificial compound feed at the adult stage, and its growth rate is more than 20% faster than that of the black snakehead, and more than 50% faster than that of the spotted snakehead....
