Poor pond bottom quality can significantly increase shrimp mortality, resulting in lower harvests and reduced profits. As well, shrimp production can make a build-up of organic matter about the pond floor, including feed residue, waste material, and dead organisms – often called sludge. In just right quantities it has a detrimental effect on water quality and shrimp health. To combat these producers require an effective management plan which monitors the sediment levels of their ponds. Below are a few general tips they need to consider following.

A pond liner can be a geomembrane structure which offers decisive protection to shrimp farms and the aquatic environment around them. Sulfide buildup, anoxic reactions, and pond bottom erosion can be deterred through the use of pond liners crafted from high-density polyethylene (HDPE) or concrete, facilitating a controlled system for pond management and water quality monitoring. Concrete has proven to be the most resilient option in relation to pond liners since it’s heavy-duty material allows for fixed measurements of pond depth and width without giving straight into drastic changes after a while. Better technology has allowed the cultivation of healthier aquatic environments for shrimp farming, as a result of pond liners that are robust enough to battle against toxins.

Pond design is a consideration for virtually any pond owner, and pond liners supply the key to optimal performance. Based on the pond size, pond liners could be developed in three shapes: rectangular, square, or round. Each shape features its own associated positives and negatives intended for water current and sediment accumulation. Our recommendation is that pond owners opt for the square or even a round pond because they represent the best choice in terms of optimizing water circulation. Additionally, aerators in many cases are employed in conjunction with pond liners of a geomembrane material as they help create centrifugal currents that move settled solids towards pond’s center where they subsequently can be taken off via pumping or by having a piping system coupled to the central drain. Therefore a highly effective pond bottom design should add a central drain to minimize the quantity of sedimentation and be sure easier sludge removal.
