  • Species mix checked for juvenile yellowfin and bigeye
  • Histamine and salt results reported against each lot code
  • Bandsaw-cut steaks for foodservice and retail

Product Specifications

Indicative; confirmed per lot on each quotation.

Origin
Mainly Western and Central Pacific and Indian Ocean purse-seine fisheries, landed for processing in Thailand, with pole-and-line skipjack from partner origins on request; ocean, FAO area and vessel flag declared per lot.
Grade / Size
Whole round by individual fish weight (e.g. 1.4⁠–⁠1.8 kg, 1.8⁠–⁠2.5 kg, 2.5⁠–⁠3.4 kg, 3.4 kg up); loins by piece weight and grade; steaks by thickness or portion weight agreed per order.
Form & Processing
Whole round, brine-frozen at sea; precooked loins (steamed, cleaned, vacuum-packed and frozen); raw frozen loins; bandsaw-cut steaks, IQF or interleaved.
Storage
Hold at -18 °C or colder with minimal fluctuation; thaw loins and steaks under refrigeration and keep thawed fish cold, since warmth allows histamine to form.
MOQ
Whole round by the full reefer container; loins and steaks from one pallet per grade, combinable with other frozen fish in a mixed container.
Lead Time
Typically 3⁠–⁠6 weeks once the specification is agreed; purse-seine landings and seasonal FAD closures can shift the availability of particular sizes.

Product overview

Skipjack is the volume tuna of world trade, and most of the catch ends up in a can or a retort pouch. Thailand is one of the leading tuna canning centers in the world: purse-seine carriers discharge frozen skipjack in Bangkok for loining and canning plants, many of them close to the capital, and the Bangkok skipjack price is followed across the industry as a reference. Our offers serve buyers along that chain, from canners and pouch packers who need raw material by species and size, to loin buyers who would rather not butcher whole fish, to distributors placing steaks with foodservice and retail customers.

Katsuwonus pelamis is a fast-growing tropical tuna caught mostly by purse seine, either on free-swimming schools or around fish aggregating devices (FADs), with a smaller pole-and-line catch from fisheries such as the Maldives and parts of Indonesia. Most raw material reaching Thai processors comes from the Western and Central Pacific, the largest skipjack fishery, with further lots from the Indian Ocean, landed by vessels on the authorized lists of the relevant tuna commission, WCPFC or IOTC. Every offer names the ocean, FAO area, gear and vessel flag, because those details decide which catch documents your market needs and tell you how the fish were handled on board.

Whole round fish are frozen in brine in the vessel’s wells and graded by individual weight, in bands such as 1.4⁠–⁠1.8 kg, 1.8⁠–⁠2.5 kg, 2.5⁠–⁠3.4 kg and 3.4 kg and up, since yield and cannery throughput both change with size. Precooked loins are made by thawing, steaming and cooling the fish, then removing skin, bones and dark meat before the loins are vacuum-packed and frozen; raw loins and bandsaw-cut steaks are frozen without cooking. Lots are checked for species mix, since purse-seine sets can include juvenile yellowfin and bigeye, and for size spread, salt taken up from the brine, burst bellies, crush damage and histamine. Precooked loins are also assessed for color, texture, bone fragments and leftover dark meat.

Canneries in Europe and other markets buy precooked loins to fill cans and pouches locally, and Japanese makers of katsuobushi and dashi flakes buy whole frozen skipjack as their raw material. For sashimi and steak menus that call for deeper red, firmer meat, see frozen yellowfin tuna. Heads, frames and other streams from tuna loining are covered under fish processing by-products, and the guide to reefer containers and cold chain explains set points and the records a claim depends on.

FAQ

Frozen Skipjack Tuna: questions from buyers

What is the difference between precooked and raw skipjack loins?

Precooked loins have already been steamed, cooled and cleaned of skin, bone and dark meat, so a cannery or pouch packer can fill them straight into containers without thawing, butchering and cooking whole fish itself. That saves labor, water and waste handling at destination, which is why loins travel to canneries working on imported raw material. Raw loins are frozen without cooking and suit steaks, seared tataki-style dishes and recipes where the buyer controls the cooking step. Each offer states which type is supplied, since tariff classification and handling differ between them.

Why does brine freezing matter for skipjack?

Purse seiners freeze their catch in refrigerated brine wells, which copes with very large sets quickly but lets some salt move into the flesh, more so when fish stay in brine longer than needed. Salt content affects the taste and the sodium figure of the finished can or pouch, so canners often set a ceiling on it. We report salt on sampled fish from whole round lots, alongside size and histamine, and buyers working to a sodium target should include that figure in the specification.

How do you handle juvenile yellowfin and bigeye in skipjack lots?

Purse-seine sets, particularly those made around drifting FADs, catch small yellowfin and bigeye together with skipjack, and at small sizes yellowfin and bigeye are hard to tell apart. The species are sorted at discharge or at the plant, and each lot is offered under the species it actually contains, because labeling rules require the correct name and catch documents record the catch by species. If you need skipjack only for a single-species label, set a maximum allowance for other tunas in the specification and we will check samples against it.

What histamine controls apply to frozen skipjack?

Skipjack muscle is rich in free histidine, which bacteria convert to histamine when fish are held too warm after capture, and once histamine has formed, cooking, canning and freezing do not remove it. Control therefore rests on rapid chilling on board and an unbroken cold chain from then on. Every lot is tested against the limits of your destination, for example the EU criteria in Regulation (EC) No 2073/2005 or the levels the US FDA applies, and the laboratory report carries the lot code printed on the cartons.
