Overview of tarpaulin fish pond culture
Fish farming in canvas pond, also known as soilless fish farming, look at the following pictures you can intuitively understand why it is called "soilless", which is a new type of aquaculture equipment and aquaculture methods, then what are the characteristics of this new type of aquaculture? What are the advantages of it? Go check it out with wolize.
One of the most obvious advantages of the canvas fish pond is that the price is cheap, compared with digging a pond made of masonry, the canvas fish pond is much cheaper, the waterproof canvas cost is lower, the PVC canvas is more wear resistant, the air tightness and waterproof performance is better, the tear resistance is better, so the service life of the canvas pool is longer; The external support is galvanized sheet, galvanized sheet itself is relatively stable, oxidation resistance is not easy to rust, the combination of the two can be used for a long time, the cost performance is relatively high, the use of galvanized sheet as a support can also save manpower, it does not need construction, convenient disassembly, and then fixed between the plate and the plate with screws.
The disadvantage is that the filtration of the canvas pool is very much in need of attention, need to be ready to pump the water out of the outside after filtration and then flow back into the tank, do a water circulation system, with the canvas pool fish, sewage is very key, if some bait residues and fish excrement are not timely eliminated at the bottom of the pool will make the water body produce ammonia nitrogen, The damage caused by ammonia nitrogen to fish can be divided into chronic and acute. The effects of chronic ammonia nitrogen poisoning on fish, such as reduced food intake, slow growth and damage to the gill tissue of fish, will make the fish in a long-term state of stress and increase the possibility of disease. Acute ammonia poisoning can cause farmed fish to become hyperactive, lose balance, convulse and even die.
Fish farming in the canvas pond depends mainly on personal farming ability, aquaculture is a technical activity after all, farming is to rely on individuals and equipment complement each other, if it is a new breed or to carefully consider.
