Icing, Filleting and Shipping the Catch Home

The catch leaves the cleaning table in the best condition it will ever be in, and everything after that point is preservation. Kill and bleed the fish within minutes, get it below 4 C (39 F) in an ice slurry, fillet it clean, and ship it frozen or near-frozen in a hard-sided cooler with a courier cutoff that still leaves a margin. The work at the table decides how the fillets eat in February. At the Belgrade Lakes farmers market in central Maine, vendors selling meat, cheese and smoked fish keep the same cold chain in a field that a boat keeps on deck: ice, shade, and a table that drains.

What happens in the first ten minutes

A fish that thrashes on the deck builds lactic acid and heat, and both work against the meat. The bleed is the first job: a cut behind the pectoral fin or through the gills, then into cold water. On the north coast, surface water in July and August sits near 12 to 14 C (54 to 57 F), which is not cold enough on its own. Bring ice.

A slurry of one part ice to one part seawater, in a cooler or a tub, drops a whole salmon below 4 C (39 F) in roughly twenty to forty minutes depending on size. Leave it longer and the flesh takes on water and turns pale. The rule the charter decks use is simple: chill fast, then move the fish to drained ice.

How do you ice a catch for a full day on the water?

Coolers are not freezers, and a day of trolling in sun burns ice quickly. Drain the meltwater every few hours, because fish sitting in fresh water loses colour and texture. Keep the slurry separate from the drinking ice. A 70-litre (18-gallon) cooler holds a 10 to 12 kg (22 to 26 lb) chinook plus ice for a full day if it starts full and stays closed.

Halibut is a different problem. A 20 kg (44 lb) fish will not fit any recreational cooler whole. Charter boats on the north coast bleed and gut halibut on the grounds, then lay them on ice in the fish box, and the filleting happens at the dock. If the fish is too large for the box, the head and guts come off first, which is also what the regulations expect.

Where the cleaning table fits

A cleaning table with a hose, a cutting board that does not slide, and a sharp fillet knife is the difference between clean loins and torn ones. Sharpen before the fish arrives, not after. Two knives, one stiff for skinning and one flexible for the cuts, cover most of the work.

The same discipline shows up far from salt water. The principle travels.

Filleting: what to cut and what to leave

Salmon: cut behind the head, run the blade along the spine, follow the ribs, and lift the fillet in one piece. Pin bones come out with pliers after the fillet is skinned. Leave the skin on for freezing; it protects the meat and it comes off easily after thawing.

Halibut: four fillets, two on each side, taken off the frame. The cheek meat is worth keeping. Trim the blood line and any grey flesh, because those are the parts that taste strong after months in the freezer.

Rinse briefly in clean cold water, pat dry, and get the fillets back on ice. A fillet left on a warm board for twenty minutes loses more quality than a fillet stored badly for a week.

Vacuum packing and freezing at the dock

Air is the enemy. A vacuum sealer at the dock or the lodge, with bags sized to a meal, beats a zip bag with the air pressed out by hand. Portion into 500 g to 1 kg (1 to 2 lb) pieces, label with species and date, and freeze flat.

A domestic freezer at minus 18 C (0 F) holds quality for roughly three to six months for oily fish like salmon, and longer for halibut, which is lean. A blast freezer at the processor takes it down faster and holds better, and many north coast towns have one within driving distance of the dock.

How do you ship fish home from the north coast?

Frozen fillets travel well if the cooler is hard-sided, the fish is frozen solid before packing, and the ice is dry ice or gel packs, not cubes. Airlines and couriers both treat dry ice as a declared item, so check the limit before the trip, not at the counter. A 20 kg (44 lb) box of frozen fillets with 2 to 3 kg (4 to 7 lb) of dry ice holds for 24 to 48 hours in transit.

Ship at the start of the week. A box that leaves Prince Rupert or Terrace on a Thursday can sit in a depot over the weekend. Keep the receipt and the tracking number, and put a phone number inside the lid.

Crossing the border with fish

Travelling south with sport-caught fish means knowing the possession limits of the province or state you are entering, and keeping the fish identifiable. Fillets with the skin on and a patch of scales left at the tail are the usual requirement for salmonids. Check the current rules for the species and the jurisdiction before you pack, because they change.

What the table decides

A catch handled well on the deck and at the table eats well for a year. A catch left warm for two hours eats like what it is. The ice, the knife and the packing are not the glamorous part of a north coast trip, and they are the part that shows up on the plate.
