Poor pond bottom quality can significantly increase shrimp mortality, resulting in lower harvests and reduced profits. Concurrently, shrimp production can certainly produce a build-up of organic matter on the pond floor, including feed residue, waste materials, and dead organisms - commonly known as sludge. In big enough quantities it features a detrimental effect on 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 must consider following.
A pond liner can be a geomembrane structure which offers decisive protection to shrimp farms and also the aquatic environment around them. Sulfide buildup, anoxic reactions, and pond bottom erosion can be deterred by using pond liners created 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 provides for fixed measurements of pond depth and width without giving straight into drastic changes after a while. Modern technology has enabled the cultivation of healthier aquatic environments for shrimp farming, as a result of pond liners which can be robust enough to address against environmental toxins.
Pond design is a consideration for any pond owner, and pond liners provide you with the step to optimal performance. Depending on the pond size, pond liners can be created in three shapes: rectangular, square, or round. Each shape possesses his own associated pros and cons pertaining to water current and sediment accumulation. It is suggested that pond owners choose either a square or possibly a round pond because they represent a good choice in terms of optimizing water circulation. Additionally, aerators in many cases are used in addition to pond liners of an geomembrane material because they help create centrifugal currents that move settled solids for the pond’s center where they subsequently are easy to remove via pumping or via a piping system coupled to the central drain. Therefore a highly effective pond bottom design should add a central drain to attenuate the volume of sedimentation and make sure easier sludge removal.
