Is The Anti-Seepage Geomembrane In Fish Ponds Harmful To Fish And Shrimp?

Fish pond anti-seepage geomembrane is one of the used geotechnical materials for small family fish farming, ornamental fish ponds, and large fish pond liners. The reasons for using this material are as follows: First, the cost of the anti-seepage geomembrane material is much lower than that of concrete; the second is that the construction of the anti-seepage geomembrane material is more convenient and the transportation is simple, which can reduce the construction time and construction process. Using the impermeable membrane material can drain the water, landfill, and lay the impermeable membrane without damaging the structure of the fish pond itself, saving time and effort and becoming more and more popular!

Many people have questions, is the fish pond built with this anti-seepage geomembrane toxic, will it affect the fish, and how long can the fish live in it?

In fact, it is not difficult to answer this question. The impermeable membrane, also known as geomembrane and high-density polyethylene membrane, is made of polyethylene and anti-aging agents, antioxidants and carbon black, and other materials through special processing. These ingredients are non-toxic and harmless, and will not affect humans and animals. Thus, fish ponds laid with impermeable membranes are safe. As long as the laying is completed, fish can be released into the water.

Yet, you should also pay attention to the selection of materials. Since it is fish farming, the requirements for the materials themselves are also very strict. You must choose new material standards. If the raw materials are not used, you may not be able to keep live fish, because the new material standards are impermeable. The film is non-toxic and tasteless, and it is used for breeding. If it is not used with new materials, it will have a strong taste and will not be good for breeding.

The new material anti-seepage geomembrane also has the advantage of long service life. Under normal weather, without human damage, the fish pond anti-seepage geomembrane can be used for more than 20 years, or even longer.

For fish ponds, the thickness of the anti-seepage geomembrane is not required to be too thick. Generally, the anti-seepage geomembrane of 0.3mm-1.0mm can be selected. This thickness is thin, and special attention should be paid during transportation.

The use of PE geomembrane for waterproofing in fish ponds is equal to establishing a small ecosystem by itself. This ecosystem can not only maintain the amount of water but also prevent foreign organisms from destroying the ecological balance of the fish, reducing breeding costs.

Advantages of using anti-seepage geomembrane in fish pond culture

1. The use of anti-seepage geomembrane fish pond culture can protect the bottom and slope of the pond, and can check the water level of the pond at the same time.

2. Better control of pond water quality and increase the amount of dissolved oxygen in pond water.

3. The construction of the anti-seepage geomembrane is convenient and fast, with a short construction time and high efficiency.

4. Reduce the cost of pumping water, which can prevent the fish from escaping and digging into the mud during the rainy season, and is also convenient for fishing. The smooth surface of the geomembrane can prevent fish from escaping in the rainy season, especially fish that are good at escaping such as lobster, crab, soft-shelled turtle, loach, and yellow eel.

Disadvantages of using anti-seepage geomembrane in fish pond culture

1. The use of anti-seepage geomembranes for anti-seepage in the construction of fish ponds requires certain procurement costs. Compared with direct fish farming in digging ponds, there are more anti-seepage material costs, construction costs, and personnel costs.

2. Before laying the anti-seepage geomembrane, the treatment of the fish pond is more strict. It is necessary to ensure that the bottom of the fish pond is flat and clean, and there are no other large clods, needles, nails, and other sharp substances, so on prevent the geomembrane from sinking or scratching. The situation will affect the anti-seepage effect and the service life of the geomembrane.

Thus, there is no problem in raising fish with anti-seepage geomembrane geomaterials, but we must pay attention to the first step. When choosing geotechnical materials, we must choose a new anti-seepage geomembrane.
