Shrinkage of flounder Platichthys flesus (L.) and turbot Psetta maxima (L.) following freezing
Freezing of adult flounder Platichthys flesus and turbot Psetta maxima for 24 h resulted in mean decrease of total length (LT) of 2·1 and 1·3% and a reduced body mass (M) of 3·1 and 1·3%, respectively. Increasing the freezing time to 25 days increased the shrinkage in turbot but not in flounder. The LT and MT conversion equations for the different species and time spent frozen are given. The differences between species could be explained by the higher volume to surface area relationship in turbot compared with flounder.
