Newfoundland east and southeast coast herring : 1986 assessment / by J.P. Wheeler and R. Chaulk. : Fs70-8/87-60E-PDF

"Data analyses are presented for 1986 for the five herring stock complexes within the Newfoundland Region: 1) White Bay-Notre Dame Bay, 2) Bonavista Bay-Trinity Bay, 3) Conception Bay-Southern Shore, 4) St. Mary's Bay-Placentia Bay, and 5) Fortune Bay. Landings from the commercial fishery, which included purse seines, bar seines, traps, and gillnets approximated 4800 t, an increase of 177% from 1985. The 1982 year-class dominated both in the commercial fishery and in the research gillnet program. There were no catch rate data available from the commercial fishery and therefore cohort analysis was not attempted as reliable estimates of terminal fishing mortality could not be calculated. Minimum biomass estimates and population numbers at age were calculated from the acoustic purse seine survey using consistently surveyed core grids only. Projections were made to 1988 assuming both a fixed catch and F = 0.30 in 1987"--Abstract, page 2.
