The correct answer is option 'C' - 16.

Recirculatory Aquaculture System (RAS) is a technology used for the intensive farming of fish and other aquatic organisms. It involves the use of tanks or ponds in which water is continuously circulated and treated to maintain optimal conditions for the growth and development of fish.

The Haryana department plans to establish 16 units of Recirculatory Aquaculture System (RAS) in the state. This initiative is aimed at promoting sustainable aquaculture practices and increasing fish production in the region.

Below are the key reasons why Haryana plans to establish 16 units of RAS:

Meeting the growing demand for fish: The demand for fish in Haryana has been steadily increasing due to the rising population and changing dietary preferences. By establishing RAS units, the department aims to boost fish production and ensure a steady supply of fish to meet the growing demand.

Promoting sustainable aquaculture practices: RAS technology is known for its sustainability as it minimizes water usage and reduces the environmental impact compared to traditional fish farming methods. By adopting RAS, the department aims to promote environmentally friendly aquaculture practices and minimize the strain on natural water resources.

Enhancing fish farming efficiency: RAS units allow for better control over water quality, temperature, and other environmental parameters, which are crucial for the growth and health of fish. By establishing 16 RAS units, the department aims to enhance the efficiency of fish farming and improve the overall productivity of the aquaculture sector in Haryana.

Creating employment opportunities: The establishment of RAS units will not only increase fish production but also create employment opportunities in the state. The operation and maintenance of these units will require skilled manpower, providing a source of livelihood for local communities.

Overall, the establishment of 16 units of RAS in Haryana is a strategic move by the department to promote sustainable aquaculture practices, meet the growing demand for fish, enhance fish farming efficiency, and create employment opportunities. This initiative is expected to contribute to the economic development of the state and ensure a sustainable supply of fish for the population.
