SITKA, ALASKA The State Board of fish has made some changes to the way the sitka sound sac roe herring fishery is managed. The guideline harvest level for the commercial harvest will be based on a rate of 12 to 20 percent, depending on the size of the biomass. That’s instead of a range of 10 to 20 percent. Also, the spawning population of herring now has to be forecast at 25,000 tons or more in order to have a commercial harvest. That’s five thousand tons higher than the old threshold.
