Low-cost, high-density aquaculture technology - flow-through aquaculture

1. What is flow-through aquaculture?

Flow-through aquaculture is intensive, high-density intensive aquaculture in artificially controlled water bodies, which has the advantages of short cycle, fast growth, high yield, high efficiency and high commercial rate. Flow-fed fish farming generally increases production by about 40% compared with conventional fish farming, and is an emerging aquaculture technology worth promoting. The development of fish farming is promising, firstly, as long as there are reservoirs, rivers, mountain streams and other water resources, as long as the conditions are created for fish farming; secondly, the water flowing out of fish ponds can still be used for irrigating farmland, so as to achieve the multi-purpose use of one water, without wasting water resources.

2. How to choose the address for flow-through aquaculture?

Flow-through fish ponds require sufficient water sources, good water quality, stable water level, suitable water temperature, and water temperature between 15-30℃ between May and October. Requirements for adequate sunlight, high dissolved oxygen, feed and fish species supply convenience. Fish ponds are best built in a natural drop, and can be cited in reservoirs, irrigation canals can flow, water streams and water volume of self-flowing near, or choose to build in the non-polluting, year-round mountain springs next to the water system, or choose to build in the vicinity of the power plant, the use of waste hot water running water. Being able to utilize these running waters for fish farming can reduce production costs and improve economic efficiency.
