Freshwater Aquaculture and Geomembrane Liners

Recent concerns and regulations regarding wild harvesting and marine populations have pushed aquaculture to the forefront of the field of providing fish and aquatic life to meet growing demand. The idea of raising and rearing fish, shellfish and other aquatic organisms in a controlled environment appeals to many because of the amount of oversight that may exist in such a space. However, aquaculture operators who wish to undertake or expand their foothold should ensure that their plans include environmental considerations and the proper use of geomembrane liners.

 

Aquaculture

Aquaculture is defined as the propagation, rearing and harvesting of organisms in all types of water environments. This includes algae, fish and shellfish, such as shrimp. The increased market demand for seafood, coupled with technological developments, has created a growing interest in aquaculture. Aquaculture products can be used for food or other commercial products, to replenish wild populations, or to rebuild populations of threatened or endangered species.

Aquaculture differs from commercial fishing in that aquaculture allows the raising of stocks under controlled conditions. More than half of the food fish and shellfish consumed each year comes from aquaculture.

 

Fish and shrimp in freshwater aquaculture

The demand for fish and fish protein is increasing, leading to widespread overfishing of wild fisheries. Fish farming helps reduce pressure on wild stocks while providing the supply to meet this new demand. Aquaculturists often invest in multiple species of fish in the same pond ecosystem to take advantage of all available food sources and to combat unwanted algal blooms. Fish farming can take place in a variety of environments, from the ocean to artificial pond systems to indoor fish farming.

Shrimp aquaculture, first used in the 1970s, has grown exponentially and has changed to assist in sustainable practices. The process is now heavily regulated by government agencies, industry representatives and environmental organizations. Although lucrative and in high demand, shrimp farmers must follow many best practices to remain profitable and comply with all standards.

Much of the environmental compliance when farming fish or shrimp includes the proper use of geomembrane liners.

 

Geomembrane liners

Geomembrane liners are often used to contain hazardous liquids to ensure no contamination of groundwater or surrounding structures. They are often required in large projects and are especially necessary in aquaculture. Even freshwater fish farming requires the use of geomembrane liners as pond liners to meet all standards.

When selecting a geomembrane liner for aquaculture, it is important to work with a trusted company and take advantage of their expertise. Each pond liner project can be unique and requires careful consideration of location and project specifications in order to select the right geomembrane liner. Some of the considerations include product warranties; installation of the project; specifications of engineered materials; and costs associated with shipping, handling and installation.

Since most failures of pond liners can be traced back to the installation, it is important for companies to select reliable, experienced personnel to complete the installation. This effort at the beginning of the project will greatly reduce the potential for container leaks and their associated costs in the future. Reliable staff will also provide the customer with established evidence tracking at each step of the process so that compliance in all areas can be easily proven if necessary.
