Abstract

The invention discloses a turbot fry starter feed formula comprising the composition and content by the mass percentage: 20-35% of white fish meal, 10-20% of a chicken powder, 3-6% of an egg powder, 3-6% of beer yeast, 10-20% of wet brine shrimp, 5-10% of shrimp flesh, 15-20% of flour, 1-3% of betaine, 1-5% of fish oil, 1-3% of phospholipid, 1-2% of a vitamin mixture, 2-4% of a mineral element mixture, and 1-5% of a microorganism preparation. The turbot fry starter feed formula has the advantages of high raw material digestion and absorption utilization rate, strong feeding attraction, safety and reliability, stable quality, health, comprehensive nutrition, and convenience in use, can promote the fry metamorphosis development, improves growth performance, and improves the disease-resistant and anti-stress abilities of fry, increases the survival rate, and is suitable for large-scale cultivation of the turbot fry.

Description

[0001] Technical field: [0002] The invention relates to the field of feed, in particular to an open feed formula for turbot seedlings. [0003] Background technique: [0004] Turbot (Scophthalmus maximus Linnaeus) is native to the North Atlantic Ocean and its boundary between brackish and fresh waters. It is a rare edible fish and was introduced to my country for breeding in the mid-1990s. At present, the annual breeding output in my country is nearly 50,000 tons, with an output value of nearly 1 billion, and a complete industrial chain of seed breeding, adult fish breeding and processing and export has been formed. In view of the fact that turbot farming has become one of the main marine fish species in northern my country, and its scale is also expanding, the cultivation of turbot seedlings has also become a key issue for the development of the industry. High-quality fish fry that are safe and healthy, with neat specifications and fast growth and maturity are the necessary...
