Yellow trout is also known as golden trout because of its golden yellow body, which is a variant of rainbow trout with multiple values of ornamental and edible, and one of the excellent freshwater aquaculture species promoted by the Food and Agriculture Organization of the United Nations (FAO) to the world. To achieve good results in aquaculture, the following should be paid attention to in terms of stocking and baiting of the fry:

Golden trout fry specifications and Stocking Density: Fry stocking specifications are determined by the breeding time, water temperature and the weight of the planned market, generally between 80 to 120g/tail. Fry stocking density is subject to the water volume, water temperature, dissolved oxygen in the water and other factors, usually 1.6 to 2.2kg/m3 of water is appropriate, the fish pond should ensure that the amount of dissolved oxygen at the drainage outlet of 5mg/l or more.

Matters that should be noted when stocking fish fry: before stocking the pond should be fully exposed to the sun, and thoroughly disinfected with quicklime or bleach. The temperature difference between the fish fry transportation water temperature and the pool temperature should not exceed 5℃. The breeding pool should be sterilized with 2%~3% salt solution before stocking. Stocking of fry should be accurate in number, consistent size, and it is best to avoid high temperatures at noon to put.

Golden trout bait reference formula: Pre-reference formula 1: 60% animal bait, 40% plant bait. Fishmeal 60%, soybean cake 15%, bran 15%, coarse meal 5%, corn 5%. Add 100g of multivitamin, 166g of choline chloride and 200g of inorganic salt per 100kg of bait. ve is added at 0.1% of the fish's body weight. Meanwhile, in order to enhance the digestive function of fish, add yeast flakes appropriately. The particle size of bait should be compatible with the caliber of golden trout. Medium-term reference formula II: 50% animal bait, 50% plant bait. Fish meal 50%, soybean cake 25%, bran 15%, coarse meal 5%, corn 5%. Multivitamins, choline chloride, inorganic salts, ve and yeast amount together with the reference formula. Later reference formula 3: 30% animal bait and 70% plant bait. Fish meal 30%, plant protein powder (protein content greater than 50%) 40%, rapeseed meal 10%, black flour 15%, soybean oil 5%, plus salmon trout special additives premix.
