Fishery Management

Fish farming is a type of aquaculture where fish are bred in enclosures with the purpose of being sold as food. It is the sector of animal food production that is expanding at the highest rate. Approximately half of the world’s fish is now raised in these artificial habitats. Salmon, tuna, cod, trout, and halibut are some of the most often farmed species.

Management during summer

Warmer water has a lower ability to store oxygen, therefore catfish farming may be a better alternative during the summer. Fresh water should be circulated in the pond if irrigation is available to boost oxygen levels. Running a boat into water can help circulate and oxygenate the water.

Management During Monsoon

Pond Evacuation

During the rainy season, the volume of water will naturally increase. This is why it is critical to evacuate. Increase the depth of the pond by digging it deeper. When the depth of the well rises, the water holding capacity rises with it.

Prepare and Repair

Excessive rainfall, in most circumstances, causes dike erosion, which causes physical damage to the pond. As a result, repairing the dykes right before the rainy season is critical. Make sure to account for an appropriate slope as well. This will aid drainage as well as the management of excess water.

De-silting

Organic stuff degrades over time and settles to the pond’s bottom. This silt reacts with excess water, causing the water to deteriorate and destroy beneficial algae and zooplanktons. This is why it is very important to remove the silt before monsoon settles

Provide Oxygen-rich Water

Fish come to the top of the water for oxygen during the rainy season. This occurs as a result of a lack of dissolved oxygen. To boost oxygen delivery, immediately add fresh water or use an aerator.

Frequently Monitor Water Condition

When it rains, the pH level drops. As a result, the nature of surface water becomes more acidic. It is critical to have appropriate drainage and a plentiful supply of fresh water.

Pond Evacuation: Role of inlet and outlet

During the monsoons, you don’t want your pond to overflow. As a result, maintaining an optimal water volume is critical. During the rainy season, outlet structures can help maintain the optimal volume of water in the pond while also allowing for complete pond drainage. In most situations, a collecting area is built inside the pond to collect and drain excess water.
