Poor pond bottom quality can significantly increase shrimp mortality, leading to lower harvests and reduced profits. As well, shrimp production can create a build-up of organic matter about the pond floor, including feed residue, waste material, and dead organisms – typically referred to as sludge. In sufficient quantities it provides a detrimental relation to water quality and shrimp health. To combat these producers need an effective management plan which monitors the sediment levels of their ponds. Here are a few general tips they should consider following.

A pond liner is really a geomembrane structure that offers decisive protection to shrimp farms along with the aquatic environment around them. Sulfide buildup, anoxic reactions, and pond bottom erosion might be deterred by utilizing pond liners made from high-density polyethylene (HDPE) or concrete, facilitating a controlled system for pond management and water quality monitoring. Concrete has shown 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 into drastic changes with time. Modern technology has enabled the cultivation of healthier aquatic environments for shrimp farming, thanks to pond liners which can be robust enough to combat against environmental toxins.

Pond design is a vital consideration for any pond owner, and pond liners supply the critical for optimal performance. With respect to the pond size, pond liners could be developed in three shapes: rectangular, square, or round. Each shape possesses its own associated positives and negatives pertaining to water current and sediment accumulation. It is recommended that pond owners select either a square or possibly a round pond because these represent a good choice when it comes to optimizing water circulation. Additionally, aerators will often be used in addition to pond liners of an geomembrane material because they help create centrifugal currents that move settled solids towards the pond’s center where they subsequently can be taken off via pumping or by way of a piping system coupled to the central drain. Therefore an efficient pond bottom design should include a central drain to reduce the amount of sedimentation and ensure easier sludge removal.
