Application of simple facilities for temporary Fish Culture
At present, there are many flowing aquaculture farms in Sichuan, which mainly breed some cold-water fish, and most of their breeding facilities are cement ponds. In the earthquake, these cement pools are damaged to some extent by the earthquake destructive force, which may cause pool leakage and so on. If it is not repaired in time, the water in the pond may be lost, which will cause a crisis to the survival of aquaculture aquatic organisms, and even all the water in the pond will run out, resulting in the death of aquaculture aquatic organisms and huge economic losses to farmers.
If you want to carry out the maintenance of the culture pond, it is necessary to move the fish in the original culture pond to other places for temporary cultivation. The technology of simple temporary fish culture facilities is a system composed of simple fishing ponds and simple water cycle life support facilities, which can be easily set up in the wild. Fish can also be temporarily raised in a simple fishing pond, through a set of water cycle life support facilities to ensure that the fish can survive better in the fishing pond.

Local method to save fish poisoning

At this point, the best way is to block the toxic water into the pond first; at the same time, human urine on the whole pool of water splash. The dosage is about 25 kilograms of human urine per mu of water surface at an average depth of one meter (i.e. 667 cubic meters). After the water reaches 50 kilograms, the whole pool is evenly sprinkled, which has obvious effect on rescuing newly poisoned or unpoisoned fish. 2. Tea bran poisoning Tea bran is usually used in poison ponds or in small amounts to prevent fish diseases
