Abstract [en]

A study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m atthree locations for 14-16 days each. The other consisted of profilemeasurements at each location at four times during the period of six weeks. Forthe current measurements two instruments (model RCM 9) were used. A two weekmeasurement can give enough data to make an evaluation of how the currents at alocation will transport litter from a fish farm. A longer probing time wouldhowever be desirable since the currents along the northern east coast of Swedenare mainly driven by factors that are changing during the year such as airpressure, temperature, precipitation etc. Water current measurements can be ofgreat help both when determining how particles from a fish farm is dispersedand also for governing authorities in the processes of both allowing new fishfarms and also when supervision of fish farms is needed.
