Atlantic Gum Culture Technology (I)

I. Aquaculture environment The Atlantic gingival is a cool and warm benthic fish with a suitable temperature range of 5°C to 31°C. It can still grow normally at 29°C, but it is prone to become ill and die for a long time at high temperature. The suitable salinity range is 4 to 35. Individuals can survive in fresh water, but the salinity is less than 2.5; the survival rate is low; the illumination is less than 20001X, the suitable water surface illumination is about 7001X, the bottom illumination is 401X; the suitable dissolved oxygen is 4-12 mg/liter; the PH is suitable for the range of 6.0-8.2. Second, the growth characteristics of the Atlantic Atlantic natural gingival growth fastest in 6 to 11 months, its growth and the environment (water temperature, feed) and other conditions are closely related. Under the conditions of full-breeding, individuals who have been breeding for 1 year can grow to 35-40 cm and weigh up to 500-1000 grams. They can breed for 18 months and weigh up to 1000-2000 grams. Third, the choice of fry and transport of fry requires a complete body shape, color and normal, no deformity, bleaching individuals, the best choice for body length greater than 5 cm seed. The fry should be stopped 1 day before transportation. Before transportation, vitamin C3 (6~8)x10-6 should be fed, or 1x10-6 vitamin C should be added to the transportation water. Adding vitamin C can significantly prolong the transportation time. In addition, 5 g/m3 of Vibrio vaccine (immersion vaccine) should be used to soak the seed and transport it. Fourth, the density of cultured Atlantic gingiva significantly lower oxygen consumption rate than the brown gingivae and turbot, so the breeding density can be increased, can refer to China's land-based water culture breeding stocking density of brown gum about 2 times. Fifth, nutrient requirements and bait feed standard Atlantic gingiva commonly used feed is a high protein, high energy (high fat) food; its protein requirements 44% to 55%, fat content of 8% to 15%. 3 cm of juveniles were fed white flies with a size of 1 mm, such as 0# synthetic feed for squid and fish gills. Flour-like foods can be fed to a 5-7 cm fry stage, usually to a particle size of 1.5-2.0 mm; artificial grain feed can then be ingested. Cultivation can use particle size 3-15 mm pellet feed. It is recommended to use buoyant pellet feed for indoor cement pool and pond breeding, and to use sink pellet feed for cage culture. The feed pellet feed pellet coefficient is about 1.4.
