Fishes are aquatic animals that play a really important role in Indian food and economy. The fish market in India hit around ₹1881.84 billion in 2024, according to Expert Market Research. Fishes are cold-blooded, so they can only live in water, and they breathe through their gills.
Knowing the different types of fishes helps make better choices for nutrition and cooking. Whether buying from local markets or planning meals, knowing the different species is important for every household.
Fishes come in many different types across India’s rivers, lakes, and coastal waters. Each type has special flavours, textures, and nutritional benefits. These work well for different cooking styles and preferences.
What Are Fishes?
Fishes are vertebrate animals that live in water. They have bodies built for efficient swimming, fins for movement control, and gills that take oxygen from water. Most fishes are cold-blooded, meaning their body temperature matches the water around them.
These special creatures have scales covering their bodies for protection. They all have different shapes, sizes, and colours. This variety provides many different options for food, fun, and economic opportunities.
Fishes cannot survive outside water for too long. Their respiratory and circulatory systems are designed specifically for underwater living. That makes them totally dependent on aquatic environments.
Types of Fishes
Freshwater Fishes
Freshwater fishes live in rivers, lakes, ponds, and streams with not much salt. These species are designed to survive in non-saline environments and cannot handle saltwater conditions.
Popular Freshwater Fishes in India:
- Rohu (Labeo rohita)
- Katla (Catla catla)
- Mrigal carp
- Tilapia
- Hilsa (riverine variety)
Rohu is India’s most beloved freshwater fish. It has a silver colour. It is also quite a sweet meat. This carp species is farmed a lot and is affordable throughout the entire year.
Marine Fishes
Marine fishes live only in seas and oceans. These species have special organs to process salt and keep proper water balance in saline environments.
Common Marine Fishes in India:
- Pomfret
- Kingfish (Surmai)
- Tuna
- Mackerel
- Anchovy
Brackish Water Fishes
Some types of fishes live well in brackish water. This is a special combo of freshwater and saltwater. These fishes can handle different salinity levels found where rivers meet the sea.
Popular Fish Species in India
Freshwater Varieties
Rohu – India’s Favourite
Rohu is India’s most popular freshwater fish because of its sweet taste, minimal bones, and affordability. This large, silver-coloured carp works well in aquaculture and provides great protein value.
Bengali cuisine celebrates rohu in traditional curries. The fish’s firm yet tender texture makes it a good choice for different cooking methods, from steaming to frying.
Katla – Major Indian Carp
Katla is another great freshwater species widely farmed across India. This broad-headed fish grows quickly and has white, flaky meat. It has a mild flavour that most people enjoy.
Fish farmers prefer katla because it grows quickly and easily adapts to ponds. The species provides high nutritional value while still being affordable enough to be eaten regularly.
Hilsa – Premium Delicacy
Godavari River Pulasa fish in Andhra Pradesh is thought to be the tastiest and most expensive of the fishes in India. Hilsa has a pretty oily feel to it and a very special flavour.
West Bengal calls hilsa the “queen of fish.” Despite having quite a few small bones, its unique taste makes it expensive in markets.
Marine Varieties
Pomfret | Premium Choice
Pomfret does not have many bones, and it has white meat. This flat, round fish absorbs flavours well and cooks beautifully for special occasions.
Both silver and black pomfret varieties are popular. Silver has higher market prices due to its better taste and texture.
Kingfish | Versatile Option
Kingfish has a firm texture that holds well during different cooking methods. These include grilling, frying, and curry preparation. Its balanced flavour is great for diverse taste preferences.
Coastal states like Maharashtra and Goa especially love kingfish for its versatility and consistent availability throughout the year.

Nutritional Benefits of Eating Fishes
High-Quality Protein Source
Fishes have complete proteins with all the needed amino acids required for human health. Marine fish usually offer better texture and flavour because of their active lifestyle in big ocean environments.
A 100-gram fish serving usually contains 18-25 grams of easily digestible protein. This protein supports muscle development, tissue repair, and healthy growth in children and adults.
Rich in Omega-3 Fatty Acids
Marine fishes contain beneficial omega-3 fatty acids like EPA and DHA. These healthy fats support cardiovascular health, brain function, and reduce inflammation throughout the body.
Eating them regularly can help prevent heart disease and support cognitive function. These nutrients are also important for pregnant women and growing children.
Essential Vitamins and Minerals
Fishes provide important nutrients, including vitamin D, B12, iodine, and selenium. Marine varieties are rich in natural iodine. This helps thyroid function and metabolism.
These nutrients are usually lacking in vegetarian diets, making fishes a valuable nutritional meal. The vitamin D content supports calcium absorption for strong bones and teeth.
Low Saturated Fat Content
Most fishes naturally have minimal saturated fat while giving eaters beneficial unsaturated fats. This makes them heart-healthy protein options compared to red meat.
Even oily fish varieties have beneficial fats rather than harmful saturated fats, helping weight management and cardiovascular health.
Aquaculture and Fish Farming in India
Indian Industry
The Ministry of Fisheries, Animal Husbandry & Dairying ranks India as the world’s third-largest fish producer. Brackish water shrimp aquaculture has seen tons of growth. This contributes a lot to export incomes and domestic food security.
Modern aquaculture techniques make sure that there is a steady supply, quality control, and reduced pressure on wild fish populations. This sustainable way of doing things means they can handle India’s big need for fishes.
Farming Methods
Pond Culture: Traditional method. This uses earthen ponds where fish grow from fingerlings to a big market size. Done with controlled feeding and water.
Cage Culture: Fish are grown in floating cages within bigger amounts of water. This means there can be more fishes grown while keeping water moving.
Integrated Systems: Combining fish farming with agriculture creates sustainable ecosystems where fish waste fertilises crops and crop residues feed fish.
Industry Benefits
Fish farming provides rural employment opportunities while making sure there is fresh fish available all year. It allows targeted production of market-demanded species and reduces dependence on wild catches. This makes a huge difference to employment.
Cooking Methods for Different Fishes
Traditional Indian Preparations
Fish Curry: Most popular preparation using regional spice blends, coconut milk, and traditional techniques. Every area likes different kinds of curry.
Fish Fry: Simple to make. This is spicing fishes before light frying until golden. This method works well for most fish types.
Steamed Preparations: Healthy cooking. This keeps nutrients and natural flavours.
Regional Specialities
Bengali Cuisine: Focuses on subtle flavours using mustard oil and minimal spices to highlight natural fish taste.
South Indian Styles: Feature coconut, curry leaves, and tamarind for tangy, rich preparations special to coastal areas.
Goan Influences: Portuguese-influenced cooking using vinegar, kokum, and distinctive spice combinations creates internationally recognised dishes.
Sustainable Fishing Practices
Conservation Importance
72.1% of people in India eat fish, according to NDTV. That’s why processes that are environmentally friendly are important for the future. Responsible fishing makes sure that there is long-term ecosystem health and continued food security.
Supporting sustainable methods protects wild populations while keeping income benefits for fishing communities across India’s big coastline.
Making Responsible Choices
Deciding on farm types of fishes instead of the usual wild types of fishes is a good choice. This is because it means there will be less wild fishing, so fishes in wild waters live longer. Supporting certified sustainable fisheries promotes responsible industry practices.
Economic Impact of Fisheries
GDP Contribution
Coastal states benefit from fishing activities and seafood exports.
Export revenues from marine products bring valuable foreign exchange, supporting national economic growth and coastal community development.
Employment Generation
Fishing, processing, marketing, and more. These are all different job opportunities. Coastal areas in India depend on fisheries to live.
Health Considerations
Food Safety Guidelines
Buy fish from reputable sources that keep proper hygiene and cold storage. Fresh fish is supposed to have very red gills, transparent or see-through eyes, and quite strong bodies. There should be no unpleasant odours.
Proper cooking gets rid of most health risks. Make sure the right cooking temperatures are used, especially for pregnant women and young children.
Mercury Awareness
Large marine predators may have higher mercury levels because of environmental pollution. Pregnant women should not have too much mercury. They should rather choose smaller fishes to eat.
Freshwater fish usually have less mercury. Changing up fish choices lowers the chances of contamination.
Future of Fisheries
Technological Changes
Modern aquaculture uses ways of fishing and preparing. This includes biofloc technology and automatic feeding. These speed up how fast it takes to catch and prepare fish. In the process, it also lowers the impact on the environment.
Genetic improvement programs make faster-growing, disease-resistant fishes that improve productivity and sustainability.
Market Evolution
More and more people are learning about how healthy fish is and its protein. That means more people are buying fish. Urban consumers show more interest in diverse species and preparation methods.
Online delivery services make fresh fish easy to buy, especially in big cities where traditional markets are less convenient.
Conclusion
Fishes have great aquatic diversity that strengthens Indian cuisine, supports health, and pushes economic growth. From humble rohu in village ponds to prized pomfret from coastal waters, each species has special benefits.
Understanding fish varieties means people can make better choices for families and the environment. Eating healthy is extremely important. As India‘s aquaculture industry grows, sustainable access to diverse, nutritious fish species continues to grow.
Whether you’re a seafood enthusiast or checking out fish food, there’s always more to learn in India’s rich fishing traditions combined with the latest farming practices.
Frequently Asked Questions
Q1. How is freshwater different from marine fishes?
Freshwater fishes live in rivers, lakes, and ponds with not a lot of salt content and survive in saltwater environments. Their taste, texture, and nutritional profiles are different. Marine varieties generally have firmer flesh and stronger flavours because of their active ocean lifestyle.
Q2. Which fishes are safe for kids and pregnant women?
Small freshwater varieties like rohu, katla, and tilapia are safer for children. This is because they do not have much mercury. Plus, they have a mild flavour. These provide essential protein, omega-3 fatty acids, and nutrients needed for healthy development. Marine options like pomfret and smaller mackerel varieties are also safe when eaten in small doses. Always make sure cooking is done properly. Buy from reliable suppliers to get rid of contamination.
Q3. How can I find fresh fish when buying?
Fresh fish have super clear, bright eyes. There is no cloudiness. There should absolutely be no very strong fishy smells. The scales should be whole. They should also still have a shine. That means the fish is fresh and safe for families.
Q4. Why pick farmed fish instead of wild-caught?
Farmed fish means that wild fish don’t die out or be fished too much. Sustainable aquaculture means there are always fish without getting rid of natural systems. Modern farming focuses on the environment. This is done through handling waste and resources well. Choose farms that are very responsible.
Q5. How much fish is in a healthy diet?
People should eat fish 2-3 times every week. This provides enough protein, omega-3 fatty acids, and essential nutrients without too much mercury exposure.
