12.2.3(ii) INLAND FISHERIES

Description

Quick Overview

Inland fisheries rely on freshwater and brackish water resources for fish production, primarily through aquaculture, enhancing food security.

Standard

Inland fisheries focus on the cultivation of fish in freshwater and brackish water environments, emphasizing sustainable practices like composite fish culture. The section highlights the importance of quality seed and environmental management in maximizing fish yields.

Detailed

INLAND FISHERIES

Inland fisheries predominantly involve the farming of fish in freshwater resources such as lakes, rivers, reservoirs, and ponds. They play a vital role in food production and security. Aquaculture is the primary method of fish production, focusing on the sustainable management of various aquatic ecosystems. This section elaborates on the types of inland water bodies used, the benefits of composite fish culture, and challenges related to breeding and quality fish seed availability.

Key points discussed include:

  • Aquaculture Practices: Primarily involves cultivating fish species in confined environments, ensuring better yield and management.
  • Composite Fish Culture: This innovative approach uses a combination of multiple fish species to maximize resource use and yield. For instance, by combining surface feeders like Catla with bottom feeders like Common Carp, farmers can optimize food usage in the pond.
  • Challenges: Access to high-quality fish seed remains a significant issue in inland fisheries. The section discusses hormonal stimulation methods to breed fish successfully in controlled environments.

Through these methods, inland fisheries contribute to sustainable food production, fulfilling protein needs while ensuring environmental balance.

Key Concepts

  • Inland Fisheries: Farming fish primarily in freshwater bodies.

  • Aquaculture: Cultivation of aquatic organisms for food and other products.

  • Environmental Management: Maintaining optimum conditions for fish farming.
