RFW: refrigerated freshwater; RSW: refrigerated seawater.

a

RSW and slurry ice are included as a storage method on‐board the fishing vessels, which can also be responsible for water uptake.

b

Storage time selected from the information available in the article as the closest to 5 days (maximum duration considered in the present assessment).

c

Weight change is considered to be due to water uptake. Increases or decreases are calculated as percentages with respect of the water content of fish at time 0 (at the beginning of the storage).
