Abstract

Studies on the long term storage of living saithe, Pollachius virens Linnaeus, 1758. FiskDir. Skr. Ser. HavUnders., 16: 279-300. In order to observe how far muscle nutrition is affected during long term starvation, saithe were stored under natural and laboratory conditions. The results show that changes in the liver and condition indices were similar under both conditions. The analyses of protein, water, lipids, carbohydrates and ash content indicate that in the white muscle there is a loss of protein during starvation. The protein loss is replaced by water. Such a correlation was not found in red muscle. There was no definite trend in carbohydrate and ash content of muscles with advance of starvation. The overall picture of the various chemical analyses shows that the organic material from white muscle is mobilised when the saithe are starved, whereas there is little change in the red muscle.
