Iridescent Shark

Overview

For a focused fishing trip, start with managed Thai fisheries rather than assuming every river within the native range offers straightforward access. FishyAF highlights Bungsamran Fishing Park in Chachoengsao and Gillhams Fishing Resorts' Top Lake in Krabi. Gillhams lists striped catfish among its smaller-lake species; confirm current stocking, guest eligibility, and available sessions before booking. Bungsamran's current address is in Chachoengsao, not its former Bangkok location.

Key Details

Wild distribution centers on Southeast Asian river basins, including the Mekong and Chao Phraya. Floodplain connections matter alongside the main channel. Seasonal movements take fish between permanent river habitats and inundated feeding areas, so yesterday's productive stretch is not necessarily tomorrow's holding water. There is no single defensible fishing depth that applies across those environments.

Angler Insight

At a stocked lake, ask staff where striped catfish are currently feeding and whether a float or bottom presentation is producing. Gillhams specifically recognizes float fishing as an option on its Top Lake. Treat river fishing as a separate undertaking requiring local access knowledge, safe positioning, and conservation checks. Choose a lawful managed fishery when your priority is learning the species rather than solving a river-scale migration puzzle.

Overview

FishyAF rates every month as good for this species in suitable managed fisheries. That is a year-round opportunity rating, not a promise of equal catches in every month or every water. For a stocked Thai lake, recent feeding activity and the venue's operating schedule are more useful starting points than a universal calendar date.

Key Details

Wild Mekong movements follow changing water levels and differ between river sections. Historical observations describe upstream movement during falling water in parts of Cambodia, while spawning-related activity and downstream movement occur around the developing flood season. Eggs were reported across several months, with a pronounced June–July peak in the surveyed lower-basin areas. Those observations describe biology, not an automatic recommendation to target spawning fish.

This is a tropical species, but there is insufficient evidence here to prescribe one precise water temperature or a universally superior dawn, dusk, or nighttime bite. Do not turn a local pattern into a species-wide rule.

Angler Insight

Ask the fishery when feeding activity has been strongest during the preceding few days, and fish within its authorized hours. Compare presentations during your session instead of waiting stubbornly for a supposedly magical hour. In rivers, check flood conditions and spawning protections first; the easiest seasonal concentration to locate is not necessarily appropriate to exploit.

Overview

Float and feeder fishing are the practical starting methods in the FishyAF record. Both let you present bread paste or rice-bran dough without pretending this omnivorous catfish is primarily a lure target. Gillhams also identifies ledgering and float fishing as suitable approaches on its Top Lake.

Key Details

For adult striped catfish, the supplied starting loadout is an 8–10-foot medium-heavy bait rod, a 5000–6000 spinning reel with a smooth drag, 20–30-pound monofilament, and a 30–40-pound abrasion-resistant hooklink. Use a strong single hook with a running feeder or adjustable float, subject to venue approval. This is a starting setup, not permission to ignore heavier fish sharing the water.

From shore, prioritize controlled casting and a clear landing area. Adjust float depth to observed feeding rather than automatically putting everything on the bottom. A boat is not essential for the managed fisheries highlighted here. Expect to manage the fight with your drag and rod angle rather than trying to win through a locked spool.

Angler Insight

Ask staff to approve the whole rig before casting, especially where Mekong giant catfish share the lake. Keep the rod secured, allow a taking fish to draw line safely, and follow the venue's landing procedure. At Gillhams, staff handle netting, and their decisions on tackle and fish care take priority.

Overview

Bread and rice bran are the best starting baits in the supplied FishyAF record. Use bread paste or rice-bran dough as a presentation you can cast and maintain, rather than treating a secret flavor as the entire method. This fish's omnivorous biology supports a broader feeding strategy than its shark-like appearance suggests.

Key Details

For float fishing, check that the hook bait stays attached during the cast and remains presented at the chosen depth. For feeder fishing, adjust the mixture so it survives delivery but releases material after reaching the water. Start with the fishery's recommended preparation before changing ingredients or adding attractants.

Other natural foods are documented in the species' diet, but a diet record does not prove an item is an effective adult angling bait. Historical fisheries documentation mentions ant eggs and worm pieces for catching fingerlings; that is not a reason to abandon established bread-based tactics for adult fish.

Angler Insight

There is not enough verified species-specific evidence here to recommend a particular artificial lure. Some venues also restrict lure fishing by lake. Confirm permitted methods and bait sourcing before bringing supplies: Gillhams restricts outside bait, prohibits live fish bait, and allows lure fishing on its smaller lake rather than the main lake. Match the rules first and the bait second.

Overview

FishyAF's practical average-size guide is 24–36 inches and 5–20 pounds. Use that as an expectation for ordinary target fish, not a guaranteed venue average or a strict conversion between length and weight. Individual condition, age, feeding, and the fishery's stock all influence what reaches your net.

Key Details

Published references report a maximum length of 130 centimeters standard length and a maximum published weight of 44 kilograms, roughly 97 pounds. Standard length excludes the tail fin, so it should not be casually equated with an angler's nose-to-tail measurement. Those published maxima describe exceptional biological size, not a confirmed recreational world-record catch.

Managed waters can contain different size classes, and a venue's biggest catfish may belong to another species entirely. Gillhams, for example, identifies Mekong and Chao Phraya catfish as its largest Top Lake fish. Do not transfer their advertised weights to striped catfish simply because they occupy the same water.

Angler Insight

Ask for the current striped-catfish size range specifically, then select tackle around the largest plausible bycatch as well as your intended target. Measure consistently, photograph identifying features, and distinguish an estimate from a scale weight. A clearly documented ordinary fish is more useful than an impressive number attached to the wrong species.

Overview

FishyAF currently lists the Iridescent Shark world record as Pending. Treat that as an unconfirmed editorial record entry, not evidence that a particular catch is awaiting certification. I could not verify a species-specific certified all-tackle holder from the publicly accessible record information checked. Recognized record databases distinguish record categories and require formal verification; a large fish pictured online does not automatically qualify.

Key Details

Published biological references report a maximum weight of 44 kilograms, approximately 97 pounds. That is exceptional size information, not a certified rod-and-reel world record. It also must not be confused with the much larger Mekong giant catfish, Pangasianodon gigas, or another shark catfish carrying a similar common name. Species identification comes before any meaningful comparison of claimed catches.

Angler Insight

If a potential record matters to you, contact the intended certifying organization before fishing. Establish eligibility, permitted tackle, weighing requirements, identification evidence, and documentation procedures. A fishery's estimated weight may be useful for its own catch log without satisfying an external authority. Plan a welfare-conscious weighing process with the venue, and accept that releasing a stressed fish promptly matters more than chasing paperwork.

Overview

Iridescent Shark fishing regulations vary by country, province, waterbody, and fishery. Its Endangered conservation status is important, but it is not itself a complete statement of fishing law. Do not assume either that all angling is prohibited or that a commercially farmed species can be caught and retained anywhere.

Key Details

Before fishing, check licensing and access requirements, protected waters, seasonal closures, permitted methods, hook restrictions, bait rules, retention provisions, and any requirements concerning transport or release. For a stocked venue, also obtain its current house rules. A day ticket does not override those conditions.

Gillhams provides a concrete example of venue-specific restrictions: its published rules prohibit live fish bait, treble hooks, and multi-hook rigs, and require staff to net fish. It also specifies its own hook-barb policy, so generic advice to use barbless hooks would be inappropriate there. Confirm which requirements apply to your booked lake and session.

Angler Insight

Send the fishery a photograph or description of your proposed rig before traveling with specialized tackle. Ask separately whether fish must be released and whether personal weighing or photography is permitted. For wild waters, obtain current guidance from the responsible fisheries authority rather than relying on an old trip report or another angler's interpretation.

Overview

Yes, this species is widely eaten. Many shoppers know it as swai, tra, sutchi, or striped pangasius rather than Iridescent Shark. These names refer to a catfish, not shark meat. Basa is a related but different species, so using the two names interchangeably can create identification and labeling confusion.

Key Details

The flesh is generally mild and white, with a relatively delicate texture. It suits steaming, baking, poaching, or frying; gentle handling helps fillets stay intact. Its restrained flavor works with straightforward seasoning or stronger sauces, depending on what you want from dinner. Farmed production supplies a substantial commercial market, so eating a traceable farmed product is a different decision from retaining a wild endangered fish.

Food safety varies; check local advisories.

Keep legally retained fish chilled, prevent cross-contamination, and cook to an internal temperature of 145°F, measured with a food thermometer. Cooking does not replace checking whether the harvest location has a contamination advisory.

Angler Insight

Never assume a fishing-park catch is available for dinner. Ask about retention before fishing and respect release requirements. If your goal is simply to try the species, purchasing properly labeled fish from a reputable supplier avoids turning a recreational catch into an unnecessary conservation or access problem.
