Francis Harbour Bight, situated near the southern end of the Labrador coast, was the centre of tagging operations in 1950. During the period June 28 to July 18, 74 salmon and 41 grilse caught in commercial gear were tagged. In this area the salmon run extends from June 10 to July 31 with the peak around June 30, and the time of the grilse run is from July 1 to August 15 with the peak around July 20. Thus the tagging period covered the last half of the salmon run and the first part of the grilse run.There was a 15% return of tagged salmon which is considered to be fairly representative. All the recaptured salmon were taken in Labrador by commercial gear. The distribution north and south of the tagging area was equal and extended to the northernmost limit of the commercial salmon fishery. The greatest distance travelled by a recaptured salmon was 186 miles, and the fastest rate of travel was 17 miles per day.The small return of tagged grilse of just over 7% is indicative of low fishing effort. The fishermen here are mainly concerned with procuring the larger salmon and in prosecuting the cod fishery.
