Description

Lifting net cage

Technical Field

The invention relates to a net cage, in particular to a lifting type net cage, and belongs to the technical field of deep sea culture equipment.

Background

The development of aquaculture, which was recorded globally by the world food and agriculture organization since 1950, was initially about 50 million tons per year, which is negligible compared to 2000 million tons per year in the fishing industry at that time. However, the aquaculture industry has developed very rapidly over time. The fastest growth since 1990 has just come to the stagnation of fishing and is being evaluated by the food grower organization as the fastest growing food industry worldwide. In 2015, the global aquaculture yield reaches +/-9000 ten thousand tons, which is equivalent to the yield of the global fishing industry.

In 2015, the aquaculture industry was dominated by Asia with a total production of +/-8000 million tons accounting for +/-89% of the global production. The total yield in china is +/-4760 million tons (53% of global yield), followed by india, the total yield is +/-490 million tons, followed by the three largest producing countries in southeast asia, indonesia, the total yield is +/-430 million tons, the total yield in vietnam is +/-340 million tons, and the total yield in philippines is +/-230 million tons. The total aquaculture yield in southeast Asia is +/-1120 ten thousand tons, accounting for 12.4% of the global yield. It is estimated that the production and consumption of farmed fish will continue to increase in the future, in addition to fishing.
