Sequential population analysis of the Nain assessment unit Arctic charr population / by J. B. Dempson and L. J. LeDrew. : Fs70-8/86-24E-PDF

"Tag recapture information indicated that the Nain assessment unit consists of the following subareas: Anaktalik Bay, Nain Bay, Tikkoatokak Bay and Webb Bay for the inshore zone, and Dog Island and Black Island for the offshore zone. Annual landings from this assessment unit have ranged from 34 to 76 t (mean = 56 t) and from 1977-1985 have represented 36% of the total commercial production from the Nain Fishing Region. The total allowable catch in 1985 for the Anaktalik Bay and Tikkoatokak Bay subareas, including an offshore component was 30.5 t. Landings for the Nain assessment unit in 1985 totaled 41 t and were 6% higher than the previous year. A sequential population analysis was carried out on catch at age data from 1977-85 and indicated a fishing mortality of 0.45 in 1985. A projection of the TAC in 1986 fishing at F0.1 (= 0.40) indicates a yield of 44 t"--Abstract.
