In India being a developing country, there are different ways people do aquaculture:
Farming fish in freshwater: In India, people use rivers, lakes, and ponds to raise fish like carp (rohu, catla, and mrigal), tilapia, and prawns. They create special ponds and sometimes combine fish farming with agriculture. Example: Fish farmers in West Bengal raise carp fish in ponds alongside rice cultivation.
Farming fish in salty water: India's coastal areas are suitable for farming fish in water that is a bit salty. People cultivate shrimp (tiger shrimp, white shrimp) and other fish like mullet and milkfish. They use ponds or control the environment by mixing seawater. Example: In Tamil Nadu (Rameshwaram) and Andhra, farmers rear tiger shrimp in ponds along the coastline.
Farming marine creatures in the sea: Some places in India farm marine species like seabass, grouper, cobia, and pearl oysters. They do this in the open sea or using special cages, pens, or floating rafts. Example: In Gujarat, fish farmers use floating rafts to raise seabass in the Arabian Sea.
Ornamental Fish Farming: India has a significant presence in the global ornamental fish trade. Many small-scale farmers engage in the rearing of ornamental fish species like guppies, angelfish etc. Ornamental fish farming is typically practiced in places like Kerala and at small tanks or ponds and requires careful maintenance of water quality and breeding conditions.
Even places not around the coast of India have set up their bio-floc farms..

@all Aquaculture, or the farming of aquatic organisms, plays a significant role in addressing food security, economic development, and poverty alleviation in many developing countries. Here are some common aquaculture practices found in developing countries:
Pond Culture: Pond culture is one of the most widely practiced aquaculture methods in developing countries. Farmers construct ponds or reservoirs to raise fish, crustaceans, or mollusks. Ponds can be small-scale, backyard operations or larger commercial ventures. Commonly cultured species include tilapia, catfish, carp, and shrimp.
Cage Culture: Cage culture involves confining fish or other aquatic species within floating cages in natural or artificial bodies of water such as lakes, rivers, or coastal areas. This practice is popular in areas with suitable water bodies and provides a relatively low-cost method for fish farming.
Rice-Fish Culture: Rice-fish culture is a traditional practice in many developing countries, particularly in Asia. It involves the simultaneous cultivation of rice and fish in the same fields or paddies. The fish help control pests and weeds in the rice fields while utilizing the nutrients from the rice crop.
Integrated Multi-Trophic Aquaculture (IMTA): IMTA involves the co-cultivation of multiple species, such as fish, shellfish, and seaweed, in a way that maximizes resource utilization and reduces environmental impacts. The waste products from one species serve as nutrients for others, creating a more sustainable and efficient system.
Recirculating Aquaculture Systems (RAS): RAS are closed-loop systems that recycle and filter water, allowing for intensive fish production in limited spaces. Although RAS can be capital-intensive, they offer opportunities for higher production and better control over water quality, making them suitable for urban and land-constrained areas.
Small-Scale and Community-Based Aquaculture: Many developing countries rely on small-scale and community-based aquaculture systems, where individuals or local communities engage in fish farming to meet their own food needs and generate income. These practices often involve low-cost technologies and traditional knowledge.
Seed Production and Hatcheries: Developing countries often have seed production facilities and hatcheries to produce fish fry, shrimp post-larvae, or other aquatic juvenile stages. These facilities supply farmers with quality seed stock for aquaculture operations.
Fish Farming in Reservoirs and Irrigation Canals: Some developing countries utilize existing reservoirs, irrigation canals, and other water bodies for fish farming. This practice takes advantage of existing infrastructure for aquaculture activities.
It's worth noting that aquaculture practices in developing countries are diverse and vary based on local conditions, available resources, and the targeted species. Government support, technological innovation, capacity building, and knowledge transfer are crucial for the sustainable development of aquaculture in these countries, addressing food security, livelihoods, and environmental concerns.
