1. The advantages of cage fish culture technology are:
(l) The use of lakes, reservoirs, rivers and other large and medium-sized water areas and shallow seas, harbors and other water areas for fishery production can improve the utilization of land and resources and the efficiency of use. It does not occupy arable land, borrow water, and reuse water.
(2) Large input, large output, and high efficiency.
(3) In principle, fish that can be cultured in ponds can be cultured in cages.
(4) Applying “small-scale, high-density cage fish culture technology†in fish ponds has a disease-preventing effect.
(5) The "small-scale, high-density cage fish culture technology" can also be implemented in smaller water areas such as Shantang, Hangtang, and deepwater streams. It not only effectively uses water resources, but also has a high output (per cubic meter of production). More than 120 kilograms of fish), large profits (more than 200 yuan per cubic meter, up to more than 600 yuan high).
(6) The “seawater deep-water large cage fish culture technology†can utilize a wider range of marine fish culture areas, which is a good way for the majority of fishermen to switch to employment and produce wealth.
2. Technical points
(1) Choose suitable aquaculture waters. The selected water area must meet the ecological and growth requirements of the fish to be farmed.
(2) Design, manufacture and set up cages according to technical requirements.
(3) Choose suitable cultured fish, determine stocking specifications, stocking time, stocking rate, and stocking methods and methods.
(4) Design, produce, or purchase special artificial pellet feeds for the farmed species.
(5) Do a good job of daily feeding and management, such as feed feeding, water quality monitoring, disease prevention, and inspection and maintenance of cage facilities.
Cage culture technology is a technology that uses cage facilities in fish breeding in lakes, reservoirs, river channels, shallow seas, and harbors, including “small-scale high-density cage fish culture technology†and “shallow sea deep-water cages†Fish farming technology is a new technology in cage fish farming technology.
