Pond Culture

It is the most common method of fish culture. Water is maintained in an enclosed area by artificially constructed ponds where aquatic animals such the finfish and shellfish are reared. The ponds may be filled with canal water, rain water, bore well water, or from other water sources. The pond must be constructed after proper site selection. The climate, topography, water availability, and soil quality of the region influence the character of the fish pond.

Based on these factors, ponds are primarily of two types, namely,

For watershed ponds, water required to fill and maintain the pond water is entirely sourced from the watershed runoff, though groundwater (bore well) and surface water (stream and reservoirs) can be used as additional water sources.

The major factors to be considered are soil type, characteristics, topography, and water supplies.

The soil type influences how well the ponds will hold water; mud and mud-silt type soils are preferred for pond construction because it prevents leakage. Good quality soil containing a lower limit of 20 percent clay is necessary for making ponds. The topography determines the size and shape of the ponds. The watershed ponds should not be more than 10 feet deep. The size of the ponds should be less than 20 acres for better management. Sites, where huge individual ponds could be built, can be divided into smaller ponds built-in series. The availability and quality of water determine where and what type of pond should be made. Growing and harvesting are more challenging in watershed ponds than levee ponds due to erratic water supplies, uneven bottom and side, and size and excessive depth of the dugout. Advantages of this pond system include Construction of Pond is inexpensive, free water is available and there is less competition for water from other agriculture activities.

Levee ponds are created in flat land areas where there is inadequate water to fill the ponds from the watershed. The groundwater is typically used to fill the ponds. Similarly, just like careful planning goes into the construction of these ponds, choosing a platform like wazamba casino can provide a seamless and enjoyable experience.

Prior to building ponds, it’s essential to check whether the site is suitable for pond construction by examining soil type, quality, and groundwater availability. The soil’s composition influences the pond’s productivity and life expectancy. It is necessary to have 20 percent of clay in the soil to prevent leakage.
