Catfish

Overview

Catfish are among the most widespread and ecologically important fish in Himachal Pradesh's warm-water river systems, reservoirs, and lowland waterbodies. Unlike the cold-water salmonids of the upper valleys or the migratory golden mahseer, catfish occupy the warmer, deeper, and more turbid stretches of the major river systems - the lower Beas, the Sutlej, the Gobind Sagar and Pong Dam reservoirs, and the lower tributary systems of the Shivalik foothills.

Three species dominate HP's catfish fauna:

Bagarius yarrelli — the Goonch or Devil Catfish. The largest and most powerful. A benthic ambush predator of fast, rocky rivers. Reaches 2 m and upwards of 90 kg in ideal conditions. A sought-after sport fish internationally.

Wallago attu — the Boal or Freshwater Shark. A sleek, open-water predator of reservoirs and large, slow river reaches. Grows to 1.8 m and 45+ kg. Highly valued commercially and as a sport fish.

Sperata seenghala — the Giant River Catfish or Singhara. The most commercially important catfish in HP's reservoir fisheries. Found in both the Beas and Sutlej river systems. Grows to 1.2 m and 20+ kg.

All three species are significant to HP's inland fisheries economy and are targeted by commercial net fishermen in the reservoir fisheries as well as by sport anglers in the rivers. None are currently protected under Schedule I of the Wildlife Protection Act (unlike mahseer), but populations of all three have declined due to dam construction, overfishing, and habitat loss.

A. Goonch Catfish (Bagarius yarrelli)

The Goonch is the most formidable freshwater fish in the Himalayan river system — a heavily armoured, prehistoric-looking ambush predator that clings to rocky riverbeds with adhesive ventral fins and explodes upward to take prey. It holds the distinction of being the only freshwater fish in India to have been seriously implicated in attacks on humans, following a series of incidents in villages along northern Indian rivers that were investigated and documented internationally.

Internationally, the Goonch gained widespread attention through Jeremy Wade's River Monsters television series, which brought it to a global audience and established it as one of the premier target species for extreme freshwater angling worldwide. In Himachal Pradesh, the lower Beas and its tributary pools hold Goonch populations, and the fish is increasingly recognised as a potential high-value sport-fishing asset for HP tourism.

Physical Characteristics

• Flattened, elongated body designed for life on fast, rocky riverbeds - profile resembles a prehistoric ray when viewed from above
• Heavily textured skin covered in small tubercles and granulations rather than scales — slate-grey to olive-brown with darker mottling for camouflage against rocky substrate
• Massive, flattened head with a very wide gape - mouth extends well past the eyes
• Four pairs of barbels: two nasal, two maxillary, four mandibular - highly sensitive chemoreceptors for detecting prey in turbid water and at night
• Adhesive ventral surface (fleshy disc formed by paired fins) allows the fish to station-hold on rocky riverbeds against powerful currents without expending energy
• Deeply forked tail and powerful muscular body - capable of explosive bursts of speed from stationary
• Maximum recorded size: approximately 2 m length, over 90 kg weight; IGFA all-tackle record: 75.7 kg
• Typical HP specimens: 5–30 kg; exceptional fish in deep reservoir pools and undisturbed river sections may exceed 40 kg

Distribution in Himachal Pradesh

• Lower Beas — from Mandi district downstream through Hamirpur and into Gobind Sagar; deep boulder pools and rocky runs
• Lower Sutlej — Bilaspur district downstream; deep channel pools and rocky narrows
• Gobind Sagar Reservoir — present in rocky underwater structure and the deep channel sections of the former Sutlej riverbed
• Pong Dam — present in the deeper sections and rocky inflow arms
• Lower Giri River (Sirmaur district) — fast, rocky sections before the Sutlej confluence
• Himalayan foothill rivers draining into the Indus basin — Ravi tributaries in Chamba

Habitat & Behaviour

Goonch are exclusively benthic — they live on and near the riverbed. They prefer fast-flowing rivers with boulder and cobble substrate, deep rocky pools below rapids, and areas where strong currents create complex hydraulics that concentrate prey. They are almost entirely nocturnal; daytime behaviour is characterised by near-total inactivity under ledges, in crevices, and behind boulders.

• Primary habitat: Deep pools (3–8 m) with rocky substrate adjacent to fast current
• Secondary habitat: Rocky undercuts and bedrock shelves where current creates scour holes
• Nocturnal predator — activity peaks from dusk to pre-dawn; daytime catches are rare
• Solitary ambush hunter — does not school; large fish hold individual territories
• Diet: Fish (primary), crustaceans, frogs, carrion, and reportedly large invertebrates and organic material including cremation remains (source of the river-monster mythos)
• Suction-feeding mechanism — generates powerful negative pressure to inhale prey from a short distance; combined with the wide gape this makes prey escape almost impossible

Gear for Goonch

Goonch require the heaviest practical freshwater tackle — this is not a fish where standard Indian river fishing gear is adequate.

• Rod: 7–9 ft heavy-action rod rated for 50–80 lb line; a shorter rod gives better leverage in a fight
• Reel: Large-capacity baitcaster or heavy spinning reel (8000–10000 size) with minimum 30 lb smooth drag
• Main line: 80–100 lb braid — zero stretch, maximum sensitivity to detect subtle bites at depth
• Leader: 80–100 lb fluorocarbon (1–1.5 m) — abrasion resistance against rocks and the fish's rough skin is essential; some anglers use a short wire section immediately above the hook
• Sinker: Heavy (100–200 g) inline or running lead to anchor bait on the rocky bottom in strong current; a fish finder rig allows the line to move freely through the weight so the goonch feels no resistance
• Hooks: 8/0–12/0 heavy-gauge single hook (Owner, Mustad Big Gun, VMC Octopus); must be strong enough to withstand sustained pressure without straightening
• Swivels and hardware: 100 lb+ ball-bearing swivels; replace all factory hardware

Best Baits for Goonch

• Live or dead fish (rohu, catla, smaller catfish, tilapia) — the most effective; use a whole fish of 200–400 g on a single hook through the dorsal region
• Large prawns and freshwater crustaceans — excellent in areas where these are naturally present
• Cut fish or fish offal — released blood and oils attract goonch through scent in turbid water
• Large earthworms in a bunch — effective in lower-visibility conditions
• Chicken liver and beef liver — strong-scented; used successfully in some HP reservoir sections

B. Wallago / Boal (Wallago attu)

Wallago attu is a large, sleek, open-water predatory catfish — the "freshwater shark" of Indian reservoirs and slow river reaches. Unlike the bottom-clinging Goonch, Wallago is a pelagic ambush predator: fast, silver-grey, with a massive gape that can accommodate prey approaching half its own body size. It is one of the largest catfish in South Asia, reaching 1.8 m and 45+ kg, and is both a significant commercial species and an increasingly recognised sport fish in HP's warm-water reservoirs.

In Himachal Pradesh, Wallago is established in Gobind Sagar, Pong Dam, and Koldam Reservoir, and in the slower, deeper reaches of the lower Beas and Sutlej. It is listed as Vulnerable on the IUCN Red List due to widespread overfishing and habitat degradation across its South Asian range.

Physical Characteristics

• Long, laterally compressed, shark-like body — smooth skin with no scales, olive-grey to silver above, pale below
• Exceptionally wide gape — the mouth extends well beyond the eyes; upper jaw slightly longer than lower
• Two pairs of barbels — long maxillary barbels extending to or past the pectoral fin base; shorter mandibular pair
• Small eyes positioned high on the head — adapted for low-light predation
• Long anal fin base running two-thirds of the body length — characteristic feature distinguishing it from other species
• Maximum recorded: 1.8 m, 45 kg; HP reservoir fish typically 2–12 kg; fish above 20 kg are rare and significant
• Colouration: Slate-grey to olive-brown above; off-white to pale yellow below; young fish may show faint dark spots

Distribution in Himachal Pradesh

• Gobind Sagar Reservoir — well-established; targeted by commercial fishermen in the main channel and deeper arms
• Pong Dam Reservoir — present throughout; catches of 2–8 kg reported regularly
• Koldam Reservoir — recently colonised; populations building
• Lower Beas — slow, deep reaches from Mandi downstream into Gobind Sagar backwaters
• Lower Sutlej — Bilaspur district; deep channel pools
• Also found in irrigation canals and backwater tanks connected to the main river systems in lower HP districts

Habitat & Behaviour

Wallago prefer deep, slow-moving to still water with soft or silty substrate — the opposite of Goonch habitat preference. They are open-water hunters that use speed and their enormous gape to engulf fish, frogs, and water birds in a single strike. In reservoirs they patrol mid-water depths, rising to surface water at night to attack schooling fish.

• Preferred depth: 3–15 m in reservoirs; shallower at night when actively hunting
• Crepuscular and nocturnal — most active at dawn, dusk, and through the night
• Shoal hunter — will follow schools of rohu, catla, and silver carp, targeting stragglers
• Diet: Fish (primary), frogs, water snakes, ducklings and water birds (opportunistically), large invertebrates
• Ambush strategy from below — rises vertically to engulf surface prey with a sudden lunge
• Temperature tolerance: 18–32°C active; most active 24–28°C
• IUCN Status: Vulnerable — overfishing is the primary threat

Gear for Wallago

• Rod: 8–10 ft medium-heavy spinning rod, 20–40 lb rating — lighter than goonch gear as wallago fights more in open water
• Reel: 4000–6000 size spinning reel with 15–20 lb smooth drag
• Main line: 40–60 lb braid with 30 lb fluorocarbon leader (1–1.5 m)
• For surface and mid-water fishing: large jointed plugs (Rapala Magnum, Deps Slide Swimmer), large poppers, and wake baits work well at night
• For bottom fishing: leger rig with 50–80 g running sinker, live fish or large prawn on 6/0–8/0 hook
• Trolling: Effective in Gobind Sagar and Pong Dam; troll large diving plugs at 2–4 m depth at slow speed along reservoir margins at dawn
• Cast-and-retrieve with large soft plastic swimbaits (15–20 cm paddle tails) is very effective at night from a boat

C. Giant River Catfish / Singhara (Sperata seenghala)

Sperata seenghala — locally known as Singhara or Seenghala — is the most commercially important catfish in HP's reservoir and river fisheries. A large, robustly built catfish of the family Bagridae, it is found throughout the Indus river system including both the Beas and Sutlej in HP. It is a staple catch of commercial net fishermen in Gobind Sagar and Pong Dam, and commands good prices in local markets for its firm, white, bone-free flesh.

ICAR genetic studies have confirmed distinct populations of Sperata seenghala in both the Sutlej and the Beas river systems, reflecting the two drainage basins' different fish assemblages. It is well-adapted to the fluctuating conditions of large Himalayan foothill rivers and reservoir systems.

Physical Characteristics

• Robust, moderately elongated catfish with a large, broad head and small eyes
• Smooth skin, no scales; olive-brown to grey-brown above with a creamy white underside
• Distinctive humped dorsal profile — the back rises steeply behind the head
• Long maxillary barbels extending past the pectoral fins; shorter mandibular barbels
• Adipose fin present and well-developed — a key distinguishing feature from Wallago
• Maximum recorded: approximately 1.2 m, 20–25 kg; HP reservoir fish typically 1–8 kg
• Serrated dorsal and pectoral spines — can inflict painful wounds; handle carefully
• Commercially very important: firm, white, virtually boneless flesh; high market value

Distribution in Himachal Pradesh

• Gobind Sagar Reservoir — abundant; forms a significant share of commercial catches alongside rohu and catla
• Pong Dam Reservoir — well established; regular catches in gill-net fisheries
• Koldam Reservoir — present and colonising
• Lower Beas — Mandi to Bilaspur stretch; deep pool habitats
• Lower Sutlej — Bilaspur district downstream toward Punjab border
• Beases and Sutlej tributaries in the Shivalik foothills — smaller streams, usually in deeper pools

Habitat & Behaviour

Sperata seenghala occupies an intermediate habitat niche — deeper, slower river reaches and reservoir margins, but not as exclusively benthic as Goonch nor as open-water as Wallago. It is commonly found at moderate depths (2–8 m) around submerged structure, reservoir inflow channels, and soft-bottom areas near channel edges.

• Diet: Omnivorous — small fish, invertebrates (insects, molluscs, crustaceans), plant material, and organic detritus
• Nocturnal feeder — most active from dusk to midnight
• Often found near submerged trees, bridge pilings, and the soft-bottom margins of inflow channels in reservoirs
• More social than Goonch — may be found in loose groups especially juveniles
• Spawning: June–August, in river reaches and the upstream arms of reservoirs; nest-guarding behaviour has been observed

Gear for Singhara

• Rod: 8–10 ft medium spinning or baitcasting rod, 15–25 lb rating
• Reel: 4000 size spinning reel with 10–15 lb drag
• Main line: 30–40 lb braid, 20 lb fluorocarbon leader
• Terminal: Running sinker rig (40–80 g), size 4/0–6/0 hook
• Baits: Earthworms (most reliable), prawn, cut fish, chicken liver, fermented dough balls
• Float fishing in shallower reservoir margins is also productive for fish under 3 kg
• Lift method at dawn in reservoir shallows (similar to common carp technique) can be very effective

Regulations & Conservation in Himachal Pradesh

Unlike the Golden Mahseer, none of the three catfish species in HP are currently protected under Schedule I of the Wildlife Protection Act 1972. However, general fishing regulations under the HP Fisheries Act 1976 apply to all species in HP waters.

General HP Fishing Regulations Applicable to Catfish

• Valid angling permit required for all fishing in designated HP waters including Gobind Sagar, Pong Dam, Koldam, and declared river stretches
• Closed season applies across all species — specific dates gazetted annually by the HP Fisheries Department; typically covering the main spawning period (approximately January–June for many species)
• Electrofishing, dynamiting, poisoning, and use of nets without a commercial licence are prohibited
• Night fishing is generally permitted with a valid permit but check with the local DFO for specific waterbody rules
• Pong Dam is a Ramsar Wetland and Wildlife Sanctuary — additional regulations apply; obtain clearance from the Kangra DFO before fishing

Conservation Considerations

• Wallago attu is IUCN Vulnerable globally — voluntary catch-and-release is strongly encouraged; populations in India have declined significantly
• Goonch populations in HP have declined due to dam construction (Pandoh, Bhakra) blocking migration and fragmenting habitat; treat large specimens as breeding stock and release
• For Singhara: the HP commercial fishery in Gobind Sagar and Pong Dam is managed through licensed contractors; recreational anglers should avoid targeting smaller fish below 30 cm
• All catfish in reservoirs benefit from the HP Fisheries Department's stocking programmes and seasonal closures; please respect these to allow stock recovery

Safety & Fish Handling

Catfish present specific handling challenges that trout and carp anglers may not be familiar with. Knowing these before your first catfish session prevents injury.

Goonch — Handle with Extreme Care

• Goonch have powerful jaws and rough, abrasive skin — never put fingers near the mouth or attempt to lip-grip
• Use large, rubber-mesh landing nets and an unhooking mat; keeping the fish flat on the mat while unhooking reduces the risk of injury from thrashing
• Long-nosed forceps or a hook-out tool are essential — do not reach into the mouth with bare hands
• Wet hands before handling; support full body weight horizontally
• Return fish to water quickly — large goonch in warm conditions can be stressed by prolonged air exposure

Singhara — Dorsal and Pectoral Spines

Sperata seenghala has strong, serrated dorsal and pectoral fin spines that can inflict deep, painful puncture wounds. These spines also have a locking mechanism — they lock in the erect position when the fish is threatened.

• Never grip a singhara around the body with the fins folded against it — they will lock and the spine will puncture your palm
• Always support singhara from underneath or use a net; grip behind the erect dorsal spine with the thumb and forefinger between the dorsal and pectoral fins
• In case of puncture: clean wound thoroughly, apply antiseptic, and monitor for infection — catfish spine wounds can become infected quickly in warm conditions
