Poor pond bottom quality can significantly increase shrimp mortality, ultimately causing lower harvests and reduced profits. At the same time, shrimp production can create a build-up of organic matter on the pond floor, including feed residue, waste elements, and dead organisms – commonly known 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 inside their ponds. Here are several general tips they must consider following.
A pond liner is 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 might be deterred by utilizing pond liners created 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 when it comes to pond liners since it’s heavy-duty material allows for fixed measurements of pond depth and width without giving straight into drastic changes with time. Today’s technology means the cultivation of healthier aquatic environments for shrimp farming, as a result of pond liners which are robust enough to fight against toxins in the environment.
Pond design is an important consideration for almost any pond owner, and pond liners give you the step to optimal performance. Based on the pond size, pond liners may be created in three shapes: rectangular, square, or round. Each shape possesses its own associated benefits and drawbacks pertaining to water current and sediment accumulation. It is suggested that pond owners choose sometimes a square or perhaps a round pond as these represent a good choice when it comes to optimizing water circulation. Additionally, aerators in many cases are utilized in addition to pond liners of a geomembrane material because they help create centrifugal currents that move settled solids for the pond’s center where they subsequently can be taken off via pumping or by having a piping system linked to the central drain. Therefore a powerful pond bottom design should incorporate a central drain to reduce the amount of sedimentation and be sure easier sludge removal.
