Longline caught: IQF HGT Toothfish


All fish on the longliners are frozen in blast freezers down to -18°C.  This premium fish is hung by the tail and produces a beautifully straight trunk with an open gut cavity, making this form of toothfish aesthetically pleasing for the customer.  Once frozen, the tail is removed via bandsaw and each trunk is individually glazed.  IQF HGT toothfish are graded as follows:Toothfish Processing

Atlas Cove: Whole IQF or Block Frozen Icefish

MSC certified Icefish is packed whole and depending on customer needs can be IQF in cartons (around 21kg) or block frozen with full glaze (around 23kg) in a poly bag:

Small          Up to 200g per piece
Large          200g+ per piece

When packing icefish, a tray is lined with poly sheet and the appropriate grade and species label is placed face down in the tray.  Icefish are finger packed such that 20-22kg of fish are in the tray, while ensuring that the tray is not overfilled, so the fish are not squashed or distorted.

Once the fish is packed, the poly sheet is tied up to enclose the fish for best protection, then placed in the pate freezer.  If requiring a full glazed block, the tray is filled with seawater.

After freezing down to -18°C, the blocks are removed from the trays, placed into printed poly bags and sewn shut.  The bag is marked with the grade of the fish and the packing date before being stowed in the freezer hold.

MSC certified Icefish can also be further processed on shore into 6 x 1.25kg fillet packs, or to meet your specification.
