Tank Systems for Fish Culturing

Aquaculture Innovation: Growing the Future, Nurturing the Waters

A tank system for fish culturing is a land-based enclosure designed for intensive aquaculture. These tanks can be constructed from various materials such as concrete, wood, plastic, fiberglass, or steel. The system requires a complete feed diet due to the lack of natural food sources. It can operate on different types of water and air supply systems, including flow-through and recirculation. The system is designed to rear species like catfish and tilapia at high densities, requiring regular sorting to minimize mortality due to cannibalism. The system’s success relies on maintaining excellent water quality and ensuring a year-round availability of quality water.

Problem

Limited Land and Water Resources: Traditional aquaculture methods require significant amounts of land and water, which may not be available in all regions.
Lack of Environmental Control: Maintaining optimal and constant water quality conditions throughout the culture period is a challenge in traditional aquaculture.
Low Production Intensity: Traditional methods may not support the high-density rearing of species like catfish and tilapia, limiting production.
High Mortality Rates: In traditional systems, mortality due to cannibalism can be high, especially without regular sorting.
Distance from Markets: Traditional aquaculture farms are often located far from prime markets, increasing transportation costs and reducing the freshness of the produce.
Inefficient Feed Use: In open systems, a significant portion of feed can be wasted, reducing food conversion rates and promoting slower growth.
Environmental Impact: Traditional aquaculture can have a significant environmental footprint, including water pollution and habitat destruction.
Poor Biosecurity: Open systems are exposed to the external environment, increasing the risk of disease outbreaks.
High Energy Use: Traditional systems often require significant energy for water pumping and aeration.

Solution

Efficient Use of Resources: Addressing the issue of limited land and water resources, tank systems require significantly less land and water compared to traditional methods, making them suitable for areas with limited resources.
Optimal Environmental Control: In response to the lack of environmental control in traditional aquaculture, tanks provide a high degree of environmental control, allowing for year-round growth at optimum rates. Key parameters like dissolved oxygen, temperature, salinity, hardness, ammonia, nitrite, and pH can be maintained at optimal levels.
High-Density Rearing: To tackle the problem of low production intensity in traditional methods, tanks allow for intensive fish production, which is cost-effective and can meet high market demand.
Reduced Mortality: Addressing the issue of high mortality rates in traditional systems, regular sorting of fish in tanks can minimize mortality due to cannibalism.
Proximity to Markets: In response to the issue of distance from markets in traditional aquaculture, tanks can be located close to prime markets, reducing transportation costs and ensuring fresh produce.
Maximized Feed Use: To tackle the problem of inefficient feed use in open systems, tanks require a complete feed diet, maximizing food conversion and promoting rapid growth.
Lower Environmental Impact: Addressing the environmental impact of traditional aquaculture, recirculating systems in tanks can help reduce the environmental footprint of aquaculture.
Improved Biosecurity: In response to the issue of poor biosecurity in open systems, tanks, being closed systems, reduce the risk of disease outbreaks.
Energy Efficiency: To tackle the problem of high energy use in traditional systems, recirculating systems in tanks can be more energy-efficient as they recycle water within the system.

Goal 2: zero hunger

The procedures for catfish farming in tanks and cages are:

1. Stocking Density: Depending on your desired harvest size and time, choose your stocking density. For catfish in tanks, you can stock 25-gram fingerlings at a rate of 1,500 fish per cubic meter to achieve 50- to 60-gram fish in 5 weeks. Alternatively, stock at 1,000 fish per cubic meter for 100-gram fish in 9 to 10 weeks.

2. Regular Sorting: To prevent mortality due to cannibalism, it's crucial to sort the fish every two weeks. Identify and remove faster-maturing individuals from the stock.

3. Maintaining Clean Environment: In both tanks and cage systems, ensure that uneaten feed and feces do not accumulate. Regularly remove any waste material underneath the tanks or cages to prevent the proliferation of parasites and diseases.

4. Adequate Space Below Cages: Maintain a minimum distance of 3 meters below the cage. This space ensures proper water circulation through the cage and minimizes undesirable accumulation underneath.
