Fishery-independent catch data from monofilament gill-nets (3.8–15.2 cm stretched mesh) were used to estimate the selectivity of each mesh size for the protandrous species barramundi, Lates calcarifer, in the Fly River region of Western Province, Papua New Guinea. These results were used with a range of life-history parameters to simulate the effects of fishing with meshes of three sizes common to the local fisheries (8.9, 10.2 and 15.2 cm) on (1) number of sexually mature females surviving to maximum age, (2) their total egg production and (3) number of mature males surviving to fertilize these eggs. Catches in most mesh sizes approximated a normal selection curve, and the mean and standard deviation of each curve were linearly related to mesh size. Juvenile and immature barramundi (<38 cm total length) were fully selected by the common mesh sizes used in the coastal subsistence and artisanal fisheries (7.6–10.2 cm) but these mesh sizes caught few sexually mature females. Population simulations showed that the number of females surviving to maximum age and their total egg production increased as mesh size was reduced. Reducing the mesh size to increase adult female escapement may be a better management strategy than increasing mesh sizes to improve recruitment.

A New Species

Curupirina papuana sp. n. and an unnamed species of a probably new genus of Apistomyiini (Diptera : Blephariceridae) are described from the Ok Tedi, a tributary of the Fly River, Papua New Guinea. This is the first report of the family from the island; its zoogeographical significance is discussed with reference to the long-presumed role of the island in the evolution and dispersal of the tribe Apistomyiini.

A survey was carried out of the mercury content of 19 fish species from 18 locations In the coastal and fresh waters of Papua New Guinea. Most commercial catches had total mercury contents well below the 0.5 �g/g limit recommended by the World Health Organization, the only exception being barramundi (Lates calcarifer) caught in the Fly River system. The presence of mercury in this river is discussed.
