Problems solved by technology

[0003] At present, the artificial breeding of grouper in my country has not yet formed an industry, and the number of natural seedlings is limited, which seriously restricts the development of the grouper breeding industry
At present, there are mainly two ways of raising grouper artificially in high-level ponds and indoor factory breeding. High-level pond breeding is often affected by bad weather, while indoor factory breeding is not easy due to the small water body. control, it is more difficult to raise seedlings, and eventually the success rate of seedlings raised by these two seedling methods is unstable

Embodiment 1

[0031] 1. Seedling facilities and water treatment

[0032] Build an outdoor square cement pool with an area of ​​550m 2 1. The water depth of the pool is 1.8m, which is convenient to enter and drain. Lay plastic pipes with a diameter of 1 inch around the cement pool, and install air pipes of different lengths every 1.5m to inflate; the sand layer at the bottom of the pool is about 10cm, and the top of the cement pool is laid with shading sun The ceiling is closed with panels to prevent rainwater intrusion, control light and reduce the diurnal temperature difference of water body for seedling cultivation; the water quality for seedling cultivation requires clear water quality, which must be treated by sand filtration before use;

[0033] 2. Bait preparation

[0034] 2.1. Pre-treatment of seedling water

[0035] Before laying eggs, clean, level, and sterilize the nursery pool, add filtered seawater, and then add 1kg of black high-grade shrimp chips, 1kg of chlorella fertilizer...

Abstract

The invention relates to a facility fry-rearing method for grouper in a large water body of an outdoor cement pool. The facility fry-rearing method comprises the following steps of: fry-rearing facility building and water treatment, preparation before fry-rearing, incubation for fertilized eggs, feeding for bait, regulation and control for fry-rearing water body and the like, wherein fries can be caught when the whole lengths of the fries achieve 2.5 cm. The facility fry-rearing method disclosed by the invention is simple in operation, adopts a stable fry-rearing water body condition, has the advantages of being high in fry-rearing success rate, stable in survival rate, simple in operation and the like in case of no use of any antibacterial agent during the whole fry-rearing process, and is suitable for facility fry-rearing for many species of grouper in a large water body of an outdoor cement pool; and an effective way is provided for the formation of large-scale production in the aspect of artificial fry-rearing for grouper.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating seedlings of grouper in a large water body in an outdoor cement pool. Background technique [0002] After entering the 1990s, the upsurges of aquaculture in the south and north of my country have been rising one after another, and the fourth wave, known as mariculture, has appeared one after another. high demands. As the most valuable economic fish in mariculture, grouper has the advantages of less disease and fast growth. It is the most ideal choice for the marine aquaculture industry to develop high-value marine organisms. Especially when the current prawn farming is at a low ebb, many prawn farmers hope to raise high-quality fish such as grouper instead. [0003] At present, the artificial breeding of grouper in my country has not yet formed an industry, and the number of natural seedlings is limited, which seriously restricts the deve...
