specific Embodiment approach 1
[0077] Specific implementation mode one: the present embodiment is a dynamic and quantitative feeding method for leptochem salmon culture, which is carried out according to the following steps:
[0078] 1. Establishment of the bioenergetics model of lemur salmon:
[0079] 1. Physical value sub-model:
[0080] The regression relationship between the fish body energy value Et of lentinus salmon and the water temperature T and weight W:
[0088] In the formula, the unit of Cmax is g / fish / d, the u...
specific Embodiment approach 2
[0147] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the temperature of the salmon culture is lower than 22°C and higher than 6°C. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0148] Specific implementation mode three: the difference between this implementation mode and specific implementation mode one is: the culture density of lentil salmon is lower than 20kg / m 3 . Others are the same as the first and second embodiments.

Abstract
The invention discloses a dynamic quantitative feeding method for brachymystax lenok breeding, and relates to a dynamic quantitative feeding method for fish breeding. The method is aimed at solving the technical problems that the current brachymystax lenok feeding amount is mainly determined by depending on the experience of farmers or referring to other similar types such as rainbow trout, lots of feed is wasted, secondary pollution is caused, fish metabolic burdens are increased, growth efficiency is reduced, and severe negative influences are caused to fish health and welfare. The method includes the steps of firstly, establishing a brachymystax lenok bioenergetics model; secondly, establishing an optimal feeding rate model; thirdly, repeating the first step and the second step till the end of the feeding period; fourthly, generating a feeding table. The method has the advantages of being precise, efficient, environmentally friendly and the like; the scientific feeding of feed in the brachymystax lenok breeding process can be effectively guided, feed cost is reduced, secondary pollution is reduced, and the method has positive significance in maintaining the health of bred brachymystax lenok and reducing the consumption of drugs.
Description
technical field [0001] The invention relates to a dynamic quantitative feeding method for fish breeding. Background technique [0002] Brachymystax lenok (Brachymystax lenok) is a rare and valuable native salmonid fish in my country, which belongs to the genus Brachymystax lenok and lives in alpine fresh waters. Because of its tender meat, delicious taste, rich nutrition, and no intermuscular thorns, it is favored by consumers. At present, the artificial breeding technology of slender salmon has made a breakthrough, and large-scale breeding has been carried out in Heilongjiang, Liaoning, Jilin, Shandong, Shanxi, Xinjiang and other places, and considerable economic and social benefits have been achieved. However, in aquaculture production, the determination of the feeding amount of lentil salmon still mainly depends on the experience of the farmers or other similar species such as rainbow trout, and often ignores the differences in biological characteristics between differen...
