Assessment of the Voisey unit Arctic charr population in 1987 / by J.B. Dempson.: Fs70-8/88-7E-PDF
"Reported landings of Arctic charr from the Voisey assessment unit totaled 21 t in 1987 and exceeded the total allowable catch of 17 t by 25%. This catch represented 22% of the total catch of Arctic charr from the Nain Fishing Region in 1987. Landings were 28% higher than in 1986, while effort increased by 23%. Likelihood ratio statistics were used to examine temporal variation in the size composition of the catches from 1980 to 1987. Significant differences were found among years and specific time periods within the fishing season. Mean length is lower in recent years but has not declined consistently over time. The 1977-79 year-classes represented 78% of the catch in 1987. A sequential population analysis was carried out on catch-at-age data from 1977 to 1987 and suggested a reference level catch in 1988 from 14 to 17 t"--Abstract, page 2.
