Abstract: In order to improve the standardized content of laboratory red crucian carp,the aquarium suitable husbandry strategies for this kind of fish is proposed by summing up many years of practical experience and referring to the literature.Select the size of about 1200 mm × 480 mm × 755 mm (length × width × height) of the rectangular aquarium, set aeration pumps, filters, lighting and other kits, simulated pond habitat for scenery. After aeration 3 days long，the tap water is injected into the aquarium. The water quality and the environment of the aquarium were controlled goodly, maintaining the water temperature at 18-24 ℃, dissolved oxygen in ≥ 6 mg/L, pH value of pH7.5-8.5, light in the 100-200lx, hardness (CaCO3) in 95-105 mg/L, ammonia (NH3) concentration in less than 0.02 mg / L and so on. As an example of 100 mm length fish, according to the density of water per cubic meter with 80 tail fish, put the laboratory red crucian carp into the aquarium. Feeding the full-price pellets daily for 1 or 2 times, replacing part of the water every 3-7 days for 1 time, replacing all of the water for 14-21 d and cleaning the aquarium once, insisting on daily management and cleaning and disinfection. The technical method described in this article is a husbandry technical strategy suitable for laboratory red crucian carp in aquarium.
