Complex sea product cultivating system

Abstract

The complex sea product cultivating system includes fish cage for raising and catching fishes; artificial fishing rock comprising connected tubular and plate material; artificial sea weed of bagged, membrane-shaped or strip soft material connected together; small fish catcher, etc. The present invention can be elevated and moved easily to avoid damage caused by oil pollution, strong wind, billow and red tide, and has low cost and less self cultivation pollution. Fishing with cage, rather than dragnet can avoid the damage to fishing ground. The present invention may be used widely in various kinds of cultivation fields.

Description

technical field [0001] The invention relates to a culture system, in particular to a culture system applied to marine products. Background technique [0002] At present, most of the devices used for marine fish farming are floating cages, which are simple in structure, not strong enough and easy to deform, and have poor wind and wave resistance. When encountering strong winds and huge waves, the fish farming equipment will often be impacted and damaged, causing fish to be lost. , so that the farms can only be located on the nearshore water surface, but because most of the fish raised are deep-sea fish, such as grouper and fine scale, they are not suitable for breeding in the upper water surface, and the mortality rate is relatively high. Moreover, The nearshore water surface is often polluted by various oils, so that the reared fish are also polluted. In addition, in existing fish farms, weaker fish are often swallowed by stronger fish, reducing the catch, and the small fis...

[0002] At present, most of the devices used for marine fish farming are floating cages, which are simple in structure, not strong enough and easy to deform, and have poor wind and wave resistance. When encountering strong winds and huge waves, the fish farming equipment will often be impacted and damaged, causing fish to be lost. , so that the farms can only be located on the nearshore water surface, but because most of the fish raised are deep-sea fish, such as grouper and fine scale, they are not suitable for breeding in the upper water surface, and the mortality rate is relatively high. Moreover, The nearshore water surface is often polluted by various oils, so that the raised fish are also polluted

In addition, in the existing fish farms, the weaker fish are often swallowed by the stronger fish, reducing the fish catch, and the small fish debris used to feed the fish will pollute the nearby seawater and seabed. Trawlers in turn destroy fishing grounds, reducing fry and catches
