Utilization and composition of lumpfish
The results published in this report are part of the project Improved utilization of roe products. In the 2011 season, samples were taken from grayling caught in Húnaflói, Skagafjörður and Skjálfandi. Samples of gutted grayling were also obtained from two companies. The grayling was cut into five parts and individual parts were weighed. The average fillet utilization was 14% of total weight, eggs were 30%, liver 3%, spine 6%, beat 6% and whale along with head and tail 40%. Greenland halibut fillets were high in fat (8-18 g / 100g) but low in protein (8-9 g / 100g). The wave, on the other hand, was low in fat. Roe were particularly selenium-rich, but the heavy metals mercury, cadmium and lead were not measurable.
Results in this report are part of the project Increasing utilization of lumpfish. Sampling was carried out in March to June 2011 in Húnaflói, Skagafjörður and Skjálfandi. Samples were also obtained from two companies. The lumpfish were cut into five parts and the parts were weighed. Fillets were 14% of lumpfish weight, roe were 30%, liver 3%, spine 6%, viscera 6% and skin together with head and tail 40%. Fillets were rich in fat (8‐18 g / 100g) but low in proteins (8‐9 g / 100g). The skin was however low in fat. Roe were very rich in selenium but the heavy metals mercury, cadmium and lead were below the quantification limits.
