The invention discloses a salmo trutta fario linnaeus parent fish feed with low protein and amino acid balance, which belongs to the technical field of aquatic feed products, and can be used for solving the problems that no salmo trutta fario linnaeus feed exists and the protein conversion rate is low and the amino acid is unbalanced when a trout feed is used. The salmo trutta fario linnaeus parent fish feed comprises wheat middling, soybean protein concentrate, fish meal, fish oil, soybean soil, cellulose, calcium dihydrogen phoshate, inkfish paste, soyabean lecithin, ethoxyquin, arginine, methionine, phenylalanine and a premix. According to the salmo trutta fario linnaeus parent fish feed, the utilization rate of a feed raw material with lower digestibility of salmo trutta fario linnaeus is reduced, the quality of the salmo trutta fario linnaeus parent fish feed is easily controlled, the digestion utilization rate of the salmo trutta fario linnaeus parent fish feed is improved, a raw material source is stable, the cost is lowered, the problem of unbalanced amino acid of a conventional feed is overcome, the protein efficiency of the feed is favorably improved, the emission of ammonia nitrogen is reduced, the pollution to a water environment is alleviated, the anti-stress ability and the immunity of a salmo trutta fario linnaeus parent fish are improved, and the quality of sperm eggs is improved.
