| 520 | 3 |a"During the past pentad (1975-80) annual landings of herring in Fortune Bay averaged about 750 t compared with an average of 8000 t for the previous pentad (1969-74). Recently bar seines have replaced purse-seines as the major gear component. The moderate 1974 year-class continues to dominate removals; year-classes since 1974 have been extremely poor. Analyses of biomass levels based on gillnet catch-rate data (1978-80) indicate that the abundance of Fortune Bay herring have been relatively low since the mid-1970's due mainly to a combination of excessive fishing mortalities during the early 1970's and to a sequential production of extremely weak year-classes since then. Biomass levelsare projected to decline to an historical low of 2000 t in 1981. Management action should therefore be directed towards reducing the 1981 catch to the lowest practical level to ensure maximum egg deposition."--Abstract. |
