Biochemical characteristics of zooplankton entering Atlantic mackerel processing plants in Iceland as side-catch
The Northeast Atlantic mackerel ( Scomber scombrus ) is a zooplanktivorous fish with its main summer feeding grounds in the waters around Iceland. The zooplankton in the stomachs of the caught fish causes several problems during processing due to the high enzyme activity of the zooplankton. The aim...
