Ice is the no-brainer way to keep fish fresh during transportation. However, scientists at Nofima, Norway believe that ice and insulated boxes create a false sense of security and restrict innovation in the sector. According to the feed research institute, in 2010 Norway exported 922,000 tonnes of salmon – the vast majority of
this packed fresh in polystyrene fish boxes with 5–6 kg of ice per
approx. 22 kg of fish. This is equivalent to 7,500 articulated lorries
full of ice (around 230 million litres of water).
Nofima has been working on alternative methods for transportation of fish including 'super chilling'.
This method involves reducing the temperature down to the equalisation temperature of the fish, typically -1 to -2 °C. Super chilling is the easiest way of increasing the primary quality period of the fish and may be combined with packaging in a protected environment of carbon dioxide and nitrogen, during both distribution and in consumer packaging. This enables high quality to be maintained for several weeks in a cooling chain that is in accordance with the regulations (0 to +2 °C).

Aquaculture operations in Laguna Lake, The Philippines are under threat from an infestation of knife fish. Over 5,000 fishers in the lake have been affected while municipalities have also reported knife fish problems.
The Bureau of Fishery and Aquatic Resources – National Inland Fisheries Technology Center (BFAR-NIFTC) and local governments are currently undertaking mass retrieval operations to address issue.
The collected knife fish will then be turned over to BFAR for the development of technologies for its economic utilisation.

from a food technological point of view, it's a very intresting way of chilling. and it links well with this study that shows that the nutritional quality of fish does not deteriorate during freezing
