N2  - Bag sizes of game ducks in New South Wales between 1977 and 1984 were compared with antecedent annual rainfall in eastern Australia. Mean bag size is equivalent to 'catch-per-unit-effort', an index of population abundance. Annual rainfall is an index of habitat availability for waterfowl. Bag sizes of Pacific black duck and all game species combined were significantly (P<O.05) related to antecedent rainfall. Rates of increase (computed from annual catch-per-unit-effort) of black duck, maned duck and all species combined were significantly related to rainfall difference between the preceding 2 years. This study indicates that prior rainfall is a useful predictor of duck numbers in New South Wales.
