मछली उत्पादन में विविधता लाने के लिए केंद्र सरकार का राज्यों को सुझाव

The Union Government is urging states to diversify aquaculture to mitigate risks associated with over-reliance on a single species (like whiteleg shrimp), address tariff uncertainties, and adapt to the impacts of climate change on seafood exports. Diversification aims to boost overall exports by tapping into new global markets with a wider variety of aquatic species.

Integrated multi-trophic aquaculture involves farming multiple species from different trophic levels together. This approach is important because it promotes ecological balance, reduces waste, and increases overall productivity by utilizing by-products from one species as feed for another, leading to a more sustainable and efficient aquaculture system.

The indigenous fish varieties being promoted include Penaeus indicus and Penaeus monodon. Additionally, the government is encouraging the farming of species like Seabass and Karimeen (pearl spot) to reduce dependency on Litopenaeus vannamei (whiteleg shrimp).

Diversifying aquaculture can lead to increased export revenue, reduced risk from reliance on a single species, and enhanced sustainability. However, potential drawbacks include the need for new infrastructure, expertise, and market development for unfamiliar species, as well as potential ecological impacts if not managed properly.

Climate change can affect aquaculture through rising water temperatures, ocean acidification, and altered weather patterns, impacting fish health and productivity. Diversification helps by spreading the risk across multiple species with varying tolerances to environmental changes, making the aquaculture sector more resilient.

The meeting's purpose was to explore potential new markets for Indian aquaculture products. By engaging with envoys from countries like China, Russia, Iran, Venezuela, Vietnam, and Saudi Arabia, the ministry aimed to identify opportunities for export diversification and reduce reliance on existing markets.

For UPSC Prelims, remember that the Ministry advises diversifying markets and produce in aquaculture. Focus on integrated multi-trophic aquaculture, and note the indigenous varieties like Penaeus indicus and Penaeus monodon, as well as target species like Seabass and Karimeen (pearl spot).

Reforms needed include promoting research and development in disease-resistant and climate-resilient species, establishing robust regulatory frameworks for environmental protection, providing financial incentives for adopting sustainable practices, and enhancing training and capacity building for fish farmers.

Aquaculture has ancient roots, dating back to 2500 BC in China, where carp were raised in ponds. Ancient Egyptians also practiced fish farming around 2000 BC, and the Romans raised oysters and shellfish. Modern aquaculture involves technological advancements like recirculating aquaculture systems (RAS) and genetic engineering.

Recent developments include the increasing use of recirculating aquaculture systems (RAS) for better water quality control and reduced environmental impact. Genetic engineering is being explored to improve disease resistance and growth rates. There is also a growing emphasis on sustainable aquaculture practices.
