Fisheries Ebook for NABARD Grade A – Types of Fisheries in India

Fisheries in India are an important sector that provides livelihoods to millions of people and contributes significantly to the country’s economy. India has a diverse range of fisheries, including both marine and inland fisheries. Here are the main types of fisheries in India:

Marine Fisheries:
a. Coastal Fisheries: These are fisheries conducted along the coastal areas, which include the Exclusive Economic Zone (EEZ) up to 200 nautical miles from the coast. Coastal fisheries involve the capture of a wide variety of marine species such as finfish, shellfish, and cephalopods. Mechanized and traditional fishing methods are employed in coastal areas.
b. Deep-Sea Fisheries: Deep-sea fishing involves operations in the open sea beyond the coastal areas. It targets deep-water species like tuna, shark, and other pelagic fish. These fisheries require specialized vessels and equipment due to the depth and distance from the coast.
c. Offshore Fisheries: Offshore fisheries are conducted further out to sea and often involve larger vessels. They target a variety of commercial fish species found in deeper waters. This type of fishing requires substantial investment in technology and equipment.

Inland Fisheries:
a. Freshwater Fisheries: Freshwater fisheries are carried out in various inland water bodies, including rivers, lakes, reservoirs, ponds, and canals. India has a rich diversity of freshwater fish species, and these fisheries play a vital role in providing protein to the population.
b. Brackish Water Fisheries: Brackish water fisheries are conducted in estuaries and brackish water bodies, which have a mix of saltwater and freshwater. They primarily involve the farming of shrimp and prawns, along with some finfish species.
c. Cage and Pen Culture: Cage and pen culture involves the rearing of fish in enclosed structures such as cages and pens installed in rivers, lakes, or reservoirs. This method allows for controlled cultivation and is often used for high-value species.

Aquaculture:
a. Pond Aquaculture: Pond aquaculture is one of the most common forms of inland aquaculture in India. It involves the cultivation of various fish species like carp, catfish, and tilapia in specially designed ponds. Pond aquaculture is a major contributor to India’s fish production.
b. Cage and Pen Aquaculture: Similar to cage and pen culture in inland fisheries, this method is also used in aquaculture to rear fish and shrimp in enclosed structures within water bodies.
c. Marine Aquaculture: Marine aquaculture involves the farming of marine species in the open sea or coastal areas. It includes the cultivation of shrimp, seaweed, and some finfish species. Marine aquaculture is gaining importance in India due to the declining fish stocks in natural marine waters.

Integrated Fish Farming: This approach combines fish farming with other forms of agriculture, such as poultry, paddy cultivation, and horticulture, to create sustainable and diversified farming systems. It maximizes resource utilization and income for farmers.

Ornamental Fisheries: Ornamental fisheries focus on the breeding and rearing of ornamental fish and aquatic plants for the pet trade and aquarium industry. It is a niche sector but has been growing steadily in India.

These various types of fisheries in India cater to both domestic consumption and export markets, contributing significantly to the country’s food security and economic growth. However, challenges such as overfishing, habitat degradation, and environmental concerns must be addressed to ensure the long-term sustainability of India’s fisheries sector.

Fish Culture in Ponds

Fish culture in ponds, also known as pond aquaculture or pond fish farming, is a method of raising fish in man-made or natural ponds and water bodies. This practice has been in existence for thousands of years and is an important source of food and income for many communities worldwide. Fish culture in ponds is an efficient and sustainable way to produce fish for both local consumption and commercial purposes. Here’s an overview of how fish culture in ponds works:

Pond Selection:
- Choosing an appropriate site: Selecting the right location for the pond is crucial. Factors such as water availability, soil quality, and accessibility must be considered.
- Pond design and construction: Ponds can be dug in the ground or built above the ground using liners or concrete. Proper design ensures water circulation, drainage, and the ability to control water levels.
Pond Preparation:
- Soil testing and liming: Soil samples are analyzed to determine pH levels and nutrient content. Liming may be required to adjust the pH and improve water quality.
- Fertilization: Nutrients, such as organic matter and inorganic fertilizers, are added to promote the growth of phytoplankton, which serves as a natural food source for fish.
- Pond filling: Once the pond is prepared, it is filled with water from a reliable source, such as a river, well, or rainwater harvesting system.
Stocking:
- Selecting fish species: The choice of fish species depends on factors like climate, water quality, market demand, and local preferences. Commonly cultured species include tilapia, catfish, carp, and trout.
- Fingerling stocking: Juvenile fish, known as fingerlings, are introduced to the pond at the appropriate stocking density. Stocking rates depend on the species and size of the pond.
Pond Management:
- Feeding: Fish are fed a balanced diet to ensure their growth and health. The frequency and quantity of feeding depend on the fish species and size.
- Water quality management: Monitoring and maintaining proper water quality parameters, such as oxygen levels, pH, and temperature, are essential for fish health and growth.
- Disease control: Regular health assessments and disease prevention measures are implemented to reduce the risk of fish diseases.
Harvesting:
- Harvesting time: Fish are typically harvested when they reach the desired size for market or consumption. Harvesting can be done using nets or other appropriate methods.
- Grading: Fish may be sorted based on size to obtain uniform batches for sale.
Marketing and Sales:
- Fish can be sold to local markets, restaurants, or processing plants, depending on the scale of the operation and market demand.
- Marketing strategies and distribution channels vary depending on location and target customers.
Sustainability and Environmental Considerations:
- Sustainable practices, such as responsible stocking rates, water conservation, and minimizing the use of chemicals, are essential to protect the environment and maintain the long-term viability of the pond.

Fish culture in ponds can be an economically viable and environmentally friendly method of fish production, especially when managed carefully and in accordance with local regulations and best practices. It plays a crucial role in meeting the growing global demand for seafood while supporting livelihoods and food security in many communities.

Major Fish Species Bred in Ponds

In India, the major species of fish bred in ponds fall under the following categories –

Carps – Katla, Rohu, Mrigal
Catfish – Singhi, Ari, Magur
Tilapia – Kowai
Trout – Golden/Silver/Black/Silver Grey Mahseer

Polyculture in ponds has become the dominant production system in almost all parts of the world. In India, domestic and exotic carps contribute to nearly 80% of the produced from ponds. Maguire, mrigal, rohu, and Katla are the most preferred varieties of pond fish.

The Department of Fisheries helps farmers get the right quality of fingerlings. Private hatcheries are thriving in many parts of the country. The Government is also playing an active role in aiding the process through various schemes.
