Poor pond bottom quality can significantly increase shrimp mortality, resulting in lower harvests and reduced profits. At the same time, shrimp production can produce a build-up of organic matter for the pond floor, including feed residue, waste elements, and dead organisms – often called sludge. In large enough quantities it features a detrimental relation to water quality and shrimp health. To combat these producers require an effective management plan which monitors the sediment levels within their ponds. Here are a few general tips they ought to consider following.

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

Pond design is a consideration for virtually any pond owner, and pond liners supply the answer to optimal performance. With respect to the pond size, pond liners can be created in three shapes: rectangular, square, or round. Each shape possesses his own associated positives and negatives intended for water current and sediment accumulation. It is recommended that pond owners select either a square or even a round pond because they represent your best option when it comes to optimizing water circulation. Additionally, aerators will often be used in conjunction with pond liners of the geomembrane material as they help create centrifugal currents that move settled solids on the pond’s center where they subsequently is easy to remove via pumping or by way of a piping system coupled to the central drain. Therefore a highly effective pond bottom design should incorporate a central drain to reduce how much sedimentation and be sure easier sludge removal.
