Feed additive premix for low-salinity cultured marine fishes

Abstract

The invention relates to a feed additive premix for low-salinity cultured marine fishes. The feed additive premix for the low-salinity cultured marine fishes consists of multi-vitamins and composite trace elements, and 20 to 30kg of feed additive premix is added into each ton of marine fish feed, wherein the multi-vitamins are 5 to 10kg and the composite trace elements are 15 to 25kg. Long-term tests of the low-salinity cultured marine fishes in the Pearl River Delta, such as trachinotus ovatus, Japanese sea bass, sciaenops ocellatus, sparus latus, sparus macrocephalus, latescalcarfer and the like, prove that the feed additive premix for the low-salinity cultured marine fishes has comprehensive nutrition and can meet the requirement of various marine fishes on total nutrition in a low-salinity culture environment; the feed additive premix is safe and high-efficiency, does not have any toxic or side effect, makes cultured objects grow rapidly and has high feed conversion rate and good culture benefit if taken for a long time; meanwhile, the additive can obviously enhance the immunologic function and anti-stress capability of the cultured objects, and the cultured marine fishes have high vigor, bright body color and high survival rate.

Description

technical field [0001] The invention relates to a feed additive, in particular to a low-salinity cultured seawater fish feed additive premix. Background technique [0002] my country is the number one country in aquaculture in the world, and it is also the only country in the world where aquaculture production exceeds fishing production. Aquaculture occupies a very important position in the national economy. In recent years, my country's aquaculture industry has developed vigorously, especially the fourth wave of aquaculture represented by marine fish farming is in the ascendant. However, pure seawater cage culture and coastal beach culture are greatly affected by geographical location and water source, and the aquaculture area is limited, which limits the further development of natural mariculture. Under such circumstances, people vigorously promote low-salinity mariculture in coastal and estuary areas according to the physiological characteristics and characteristics of d...

AI Technical Summary

Problems solved by technology

Therefore, the seawater fish feed additive premix used in the normal seawater aquaculture environment is no longer suitable for the needs of seawater fish culture in the low-salinity seawater aquaculture environment, resulting in slow growth of cultured species, poor stress resistance, deformity rate and Problems such as high mortality rate are not uncommon

This situation seriously hinders the further development of marine fish farming under the low-salinity mode
