An assessment of American plaice in subdivision 3Ps / by W.B. Brodie and T.K. Pitt. : Fs70-8/81-37E-PDF

"An assessment using virtual population analysis was performed but there were difficulties in deriving important parameters, particularly a value for terminal fishing mortality in 1980. Projections using a partial recruitment pattern calculated from the 1977-80 catch matrix and a series of population numbers generated from VPAs with terminal F's ranging from 0.25 down to 0.15 indicated an F0.1 yield in 1982 between 4000 t and 8500 t. Due to the problems in arriving at precise values for certain parameters, it seems wise, in view of the fact that the stock is in fairly stable condition, to leave the TAC for 1982 at 5000 t which is close to the level of the average catch, 1974-80"--Abstract.
