Key concepts

Marine and inland fisheries

Marine fisheries: fishing in the seas and oceans, along the coast, on the continental shelf and in the Exclusive Economic Zone (EEZ, up to 200 nautical miles from the coast; India's EEZ is about 2 million sq km).

• West coast: Gujarat, Maharashtra, Goa, Karnataka, Kerala. The continental shelf is wider and the Arabian Sea richer; the west coast traditionally gives the larger share of marine catch.
• East coast: West Bengal, Odisha, Andhra Pradesh, Tamil Nadu.
• Islands: Andaman and Nicobar, Lakshadweep (tuna).

Main marine fish: sardine (oil sardine), mackerel, Bombay duck, pomfret, tuna, seer fish, ribbonfish; prawns and lobsters (crustaceans).

Inland fisheries: fishing in fresh and brackish water: rivers, canals, reservoirs, lakes, ponds and tanks, floodplain wetlands (beels), estuaries, backwaters (kayals) and lagoons (Chilika, Pulicat).

• Capture fisheries (catching wild fish) and culture fisheries (aquaculture: rearing fish and prawns in ponds).
• Main fish: rohu, catla, mrigal (Indian major carps), hilsa, catfish; freshwater and tiger prawns.
• Leading regions: Andhra Pradesh (aquaculture around the Godavari-Krishna deltas and Kolleru lake), West Bengal (ponds and wetlands), Odisha, Assam.

Today inland fisheries, especially aquaculture, produce more fish than marine fisheries.

Worked example

[4] Distinguish between marine and inland fisheries with two examples of fish and one area each. (Understand)

Try it first, then show the solutionSolution

1. Marine: in seas and oceans up to the EEZ - 1 mark.
2. Marine examples: sardine, mackerel, pomfret, tuna; west coast (Kerala, Gujarat) - 1 mark.
3. Inland: in rivers, reservoirs, lakes, ponds, backwaters; capture and aquaculture - 1 mark.
4. Inland examples: rohu, catla, hilsa; Andhra Pradesh, West Bengal - 1 mark.

Answer: Marine fisheries operate in the seas and oceans up to India's Exclusive Economic Zone and catch fish such as sardine, mackerel, pomfret and tuna, especially off the west coast in Kerala and Gujarat. Inland fisheries use rivers, reservoirs, lakes, ponds and backwaters, both by catching wild fish and by aquaculture, producing carps such as rohu and catla and hilsa, notably in Andhra Pradesh and West Bengal.

Inshore and deep-sea fishing; pelagic and demersal fishing

Inshore (coastal) fishing: carried out in shallow waters close to the coast, usually within about 10-20 km, using small boats such as catamarans, canoes and small mechanised boats, often for a day at a time. Most of India's marine catch comes from inshore waters; it is labour-intensive and small-scale.

Deep-sea (offshore) fishing: carried out far from the coast in deeper waters of the continental shelf and the EEZ, using large mechanised trawlers and vessels with refrigeration that stay at sea for days or weeks. It needs heavy capital and technology; India's deep-sea resources (such as tuna) are still under-exploited.

Pelagic fishing: catching fish that live near the surface or in the upper and middle layers of the water, often in large shoals. Examples: sardine, mackerel, anchovy, tuna, Bombay duck, seer fish. Gear: drift nets, gill nets, purse seines, ring seines.

Demersal fishing: catching fish and shellfish that live at or near the sea bed. Examples: catfish, croakers, soles, perches, prawns and lobsters. Gear: bottom trawls, line and hook.

Pelagic fish form the larger part of India's marine catch (the oil sardine and mackerel of the west coast are the classic examples).

Worked example

[2] Distinguish between pelagic and demersal fishing, with one example of fish for each. (Understand)

Try it first, then show the solutionSolution

1. Pelagic: fish living near the surface or in mid-water, often in shoals; e.g. sardine, mackerel - 1 mark.
2. Demersal: fish living at or near the sea bed; e.g. soles, catfish, prawns - 1 mark.

Answer: Pelagic fishing catches fish that live near the surface or in the middle layers of the sea, often in shoals, such as sardine and mackerel. Demersal fishing catches fish and shellfish that live on or near the sea bed, such as soles, catfish and prawns.

Methods of fishing and factors affecting development

Methods:
1. Traditional: cast nets, drag nets, gill nets and hook and line from catamarans (kattumaram), dugout canoes and country boats; Chinese fishing nets in Kochi backwaters.
2. Modern: mechanised boats, trawlers (bottom trawling for demersal fish and prawns), purse seiners and ring seiners for shoals of sardine and mackerel, long-liners for tuna; fish-finding echo-sounders and satellite data on potential fishing zones.
3. Aquaculture: rearing fish and prawns in ponds, tanks and cages, with feed and seed from hatcheries.

Favourable factors (physical):
1. Long coastline with indentations, bays, lagoons, estuaries and deltas, giving sheltered harbours and breeding grounds.
2. Wide, shallow continental shelf where sunlight reaches the sea bed and plankton thrives.
3. Supply of plankton, aided by river-borne nutrients and upwelling.
4. Large inland water bodies: rivers, reservoirs, tanks, backwaters.

Favourable factors (human/economic):
1. Demand: fish is a staple in coastal states (Kerala, West Bengal, Odisha, Goa); export demand for shrimp.
2. Skilled fishing communities.
3. Harbours, mechanised boats, cold storage, processing and transport.
4. Government support: fishing harbours, cooperatives, subsidies, schemes such as the Blue Revolution and the Pradhan Mantri Matsya Sampada Yojana.

Unfavourable factors: India's coastline is relatively smooth with few deep indentations, limiting natural harbours; tropical waters have many species but fewer large single-species shoals than cold seas; the monsoon makes the sea rough for months; most fishermen are poor and lack capital.

Worked example

[4] Explain four factors that favour the development of fishing along a coast. (Understand)

Try it first, then show the solutionSolution

1. Indented coastline with bays, lagoons and estuaries for sheltered harbours and breeding grounds - 1 mark.
2. Wide, shallow continental shelf rich in plankton - 1 mark.
3. Demand from local fish-eating populations and export markets - 1 mark.
4. Harbours, mechanised boats, cold storage, processing and skilled fishermen - 1 mark.

Answer: An indented coastline with bays, lagoons and estuaries provides sheltered harbours and breeding grounds; a wide, shallow continental shelf supports abundant plankton and fish; strong local and export demand makes fishing profitable; and harbours, mechanised boats, cold storage, processing units and skilled fishing communities allow the catch to be landed and marketed.

Problems of fishing in India and the need for conservation

Problems:
1. Traditional, small boats and nets; limited mechanisation and few deep-sea vessels.
2. Lack of capital and credit; poverty and indebtedness of fishermen.
3. Inadequate harbours, cold storage, processing and transport; heavy post-harvest losses.
4. Rough seas and cyclones during the monsoon; loss of life and gear.
5. Over-fishing of inshore waters, especially by trawlers, while deep-sea resources are under-used.
6. Pollution of seas, rivers and backwaters by sewage, industrial waste and oil; destruction of mangroves.
7. Conflicts between traditional and mechanised fishermen, and disputes over fishing in neighbouring countries' waters.
8. Relatively smooth coastline with few natural harbours.
9. Middlemen take much of the profit.

Need for conservation: fish are renewable only if catches stay below the rate of reproduction. Over-fishing, catching of juveniles, destruction of breeding grounds and pollution have caused declining catches of some species.

Methods of conservation:
1. Seasonal ban on fishing during the monsoon breeding season (a uniform 61-day ban on mechanised fishing on each coast).
2. Regulation of mesh size so that young fish escape; ban on destructive methods (dynamite, poison, fine-mesh nets).
3. Limits on the number of trawlers and zones reserved for traditional fishermen near the shore.
4. Protection of mangroves, estuaries and coral reefs; marine protected areas.
5. Pollution control of rivers and coastal waters.
6. Development of aquaculture and stocking of reservoirs to reduce pressure on wild stocks.
7. Awareness and cooperatives among fishing communities.

Worked example

[4] Explain the need for fish conservation and suggest three methods. (Evaluate)

Try it first, then show the solutionSolution

1. Need: over-fishing, catching of young fish, pollution and loss of breeding grounds are depleting stocks - 1 mark.
2. Seasonal ban during the breeding (monsoon) season - 1 mark.
3. Regulation of mesh size and ban on destructive gear - 1 mark.
4. Protection of mangroves and estuaries; pollution control; aquaculture - 1 mark.

Answer: Fish stocks are being depleted by over-fishing, the catching of young fish, pollution and the destruction of breeding grounds, so conservation is needed to keep fishing sustainable. Measures include a seasonal ban on mechanised fishing during the monsoon breeding season, minimum mesh sizes and a ban on destructive gear such as fine-mesh nets and explosives, and protection of mangroves and estuaries with pollution control, while aquaculture reduces pressure on wild stocks.

Case studies: Kerala and Andhra Pradesh

Kerala (west coast)
1. Long coastline (about 590 km) with backwaters, lagoons (kayals) and estuaries that provide sheltered harbours and breeding grounds.
2. A comparatively wide continental shelf off the coast and rich plankton; mud banks off the coast calm the sea during the monsoon in places.
3. Rich pelagic shoals of oil sardine and mackerel, and prawns.
4. Heavy demand: fish is part of the daily diet; dense coastal population.
5. Skilled fishing communities; cooperatives.
6. Early modernisation: the Indo-Norwegian Project (from 1952) at Neendakara (Kollam) introduced mechanised boats and better processing.
7. Harbours and centres: Kochi, Neendakara, Vizhinjam, Kozhikode; processing and export of frozen prawns.

Andhra Pradesh (east coast)
1. Long coastline (about 970 km on the traditional measure, among the longest of any state), with the deltas of the Godavari and Krishna and lagoons and lakes such as Kolleru and Pulicat.
2. The leading state in total fish production, driven by inland aquaculture of carps and shrimp in the delta districts.
3. Brackish-water prawn farming for export.
4. Harbours and centres: Visakhapatnam (a major fishing harbour), Kakinada, Machilipatnam, Nizampatnam, Nellore.
5. Large markets in Kolkata and other states and abroad; cold storage and processing.
6. Government support, cooperatives and mechanised boats.

Contrast: Kerala's strength is marine pelagic fishing and local demand; Andhra Pradesh's is inland and brackish-water aquaculture and exports.

Worked example

[2] Intensive fishing is carried on along the Andhra Pradesh coast. Justify with two reasons. (Analyse)

Try it first, then show the solutionSolution

1. Long coastline with the Godavari-Krishna deltas, lagoons and lakes (Kolleru, Pulicat) that provide breeding grounds and aquaculture sites - 1 mark.
2. Harbours such as Visakhapatnam and Kakinada, mechanised boats, cold storage and strong domestic and export demand for prawns - 1 mark.

Answer: Andhra Pradesh has a long coastline with the Godavari and Krishna deltas, lagoons and lakes such as Kolleru and Pulicat that provide breeding grounds and ideal sites for fish and prawn farming. It also has fishing harbours such as Visakhapatnam and Kakinada, mechanised boats, cold storage and processing, and large domestic and export markets for its catch.

Where students lose marks in Fishing in India

The slips examiners see most often, and what to write instead.

• ✗Mistake: Giving reasons for the wrong state or listing products

  CISCE examiners' comments, 2024: on intensive fishing in Andhra Pradesh, candidates 'Mixed up states and gave reasons for other states', 'Listed fishery products instead of reasons' and 'Said simply coast instead of indented coastline'.

  ✓Do this: Use state-specific features (Godavari-Krishna deltas, Kolleru, Visakhapatnam) and qualify physical factors ('long, indented coastline with lagoons').

  Usually costs: Up to 2 marks.

• ✗Mistake: Not linking indentation of the coastline with fishing

  CISCE examiners' comments, 2025: on an assertion-reason item about the Indian fishing industry, candidates 'Failed to link development of fishing with the indentation of the coastline'.

  ✓Do this: Remember: indentations give natural harbours and sheltered breeding grounds; a smooth coastline limits them.

  Usually costs: 1 mark.

• ✗Mistake: Confusing pelagic and demersal

  Students reverse the terms.

  ✓Do this: Pelagic = surface and mid-water (sardine, mackerel); demersal = sea bed (soles, prawns).

  Usually costs: 1 mark.

• ✗Mistake: Mixing problems and remedies

  Writing 'cold storage should be built' when problems are asked.

  ✓Do this: Problems state what is wrong; remedies come only in the measures part.

  Usually costs: 1 mark per point.

   Give two examples of pelagic fish.

   Hint

   Shoals.

   Answer

   Sardine and mackerel (or tuna, Bombay duck).

4. Q4 · 1 mark · Very short answerHarder board level

   Why do tropical seas around India have fewer large commercial shoals than cold seas?

   Hint

   Many species, small numbers.

   Answer

   Warm tropical waters hold many different species in small numbers, rather than huge shoals of a few species fed by cold-current plankton.

5. Q5 · 2 marks · Short answerHarder board level

   [2] What was the Indo-Norwegian Project and why is it important for Kerala?

   Hint

   Neendakara, 1952.

   Answer

   A development project begun in 1952 with Norwegian help at Neendakara (Kollam) that introduced mechanised boats, better gear, processing and training, modernising Kerala's fishing industry.

6. Q6 · 4 marks · Short answerHarder board level

   [4] Explain four methods of fish conservation.

   Hint

   Season, mesh, habitat, pollution.

   Answer

   (1) A seasonal ban on mechanised fishing during the breeding season. (2) Regulation of mesh size and a ban on destructive gear. (3) Protection of mangroves, estuaries and coral reefs as breeding grounds. (4) Control of pollution and development of aquaculture to reduce pressure on wild stocks.

7. Q7 · 4 marks · Short answerHOTS / competency

   [4] 'Aquaculture is the future of Indian fisheries.' Evaluate.

   Hint

   Benefits and costs.

   Answer

   Aquaculture already produces more than marine capture, earns exports (shrimp), uses India's ponds, tanks and deltas, and reduces pressure on wild stocks. But prawn farms have destroyed mangroves, salinised farmland, polluted water with feed and chemicals, and suffer disease outbreaks. It can be the future only if practised sustainably, with zoning, effluent control and mangrove protection, alongside regulated capture fisheries.

8. Q8 · 7 marks · Long answerHOTS / competency

   [7] (a) Explain the physical and human factors that have helped fishing in Kerala. [4]
   (b) Explain three problems of the marine fishing industry. [3]

   Hint

   (a) BIND.

   Answer

   (a) Physically, Kerala has a long coast with backwaters, lagoons and estuaries that provide sheltered harbours and breeding grounds, and a rich continental shelf with plentiful plankton and shoals of sardine and mackerel. On the human side, fish is part of the daily diet so demand is high, skilled fishing communities are organised in cooperatives, and the Indo-Norwegian Project and harbours such as Kochi and Neendakara modernised boats, processing and exports. (b) Most fishermen use small traditional boats and lack capital; storage, processing and transport are inadequate; and inshore waters are over-fished and polluted while the monsoon makes the sea dangerous for months.
