Consumption of fish fillet is associated with lower blood pressure in humans and other animals, whereas the effects of consuming fish residuals are less explored. To obtain high-quality fishmeal with acceptable sensory properties, the fish residuals may be washed with seawater onboard factory trawlers. This will increase the sodium content in the residuals, and whether this affects blood pressure has not yet been investigated. The primary objective of the present study was to investigate if the increased sodium content in Atlantic cod (\n                    <jats:italic>Gadus morhua<\/jats:italic>\n                    ) residuals after washing with saltwater affected the development of high blood pressure in male obese Zucker\n                    <jats:italic>fa\/fa<\/jats:italic>\n                    rats which spontaneously develop hypertension.

Blood pressure was measured on day 0 and 40. The diets containing backbone protein powder, independent of whether this fraction was washed with saltwater or not, attenuated the blood pressure increase compared to the Control group, whereas diets containing washed or unwashed head protein powder did not affect the blood pressure development.
