Analysis of the Voisey assessment unit Arctic charr populations in 1986 / by J.B. Dempson and L.J. LeDrew. : Fs70-8/87-16E-PDF
"The Voisey assessment unit, made up of Voisey Bay and the Antons subarea, was first assessed as a homogeneous unit at the end of the 1984 fishery. Annual landings have ranged from 4 to 41 t (mean = 22 t) and from 1977 to 1986 have represented 17% of the total commercial catch of Arctic charr from the Nain fishing region. Total allowable catch in 1986 was 20 t. Landings in 1986 were 17 t or 83% of the TAC. Effort increased by 44% and catch per unit effort decreased by 26% in comparison with 1985. A sequential population analysis was carried out on catch at age data from 1977 to 1986 and suggested a reference level catch of 17 t remain in effect for 1987"--Abstract, page 2.
