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.

Migrating barramundi (Perciformes : Centropomidae) spawners support a valuable artisanal fishery on the coast of south-western Papua New Guinea. This fishery declined dramatically during the 1990s shortly after the large Ok Tedi copper mine began in the headwaters of the large Fly River nearby. In order to understand the factors causing the decline, populations were sampled quarterly with gill-nets at over 20 sites throughout the Fly River from 1987 to 2001. Barramundi were most abundant in the middle and upper reaches of the Fly River. No evidence was found that output from the large Ok Tedi mine was negatively impacting on barramundi catch rates. However, the commercial fishery in the middle Fly River was found to have a negative impact on the weight of barramundi in monitoring catches in that region. Additionally, catch rates of juvenile barramundi (1 year olds) in the Fly River were negatively correlated with the amount of rainfall on the breeding grounds during the previous monsoon. This suggests that the reduced catch rates in the coastal commercial fishery in the late 1980s and early 1990s may have been affected by both the riverine commercial fishery and the El Niño (ENSO) that occurred at that time.

The present paper describes two new species of the gobiid fish genus Glossogobius from southern New Guinea and a third related species from northeastern Australia. All three species are restricted to a small number of river systems. Glossogobius bellendenensis, sp. nov. is distinctive in having reduced predorsal scales and fin-ray counts and mental frenum shape. It is restricted to relatively clear water rivers of northeastern Queensland. The closely related, Glossogobius muscorum sp. nov. is also distinctive in reduced predorsal scales and fin-ray count and is found only in the Fly River system of New Guinea. Glossogobius robertsi sp. nov. is distinctive in fin-ray and scale counts and is found in the Fly River in Papua New Guinea and possibly in a river in Papua close to the Fly River. That species has been confused with Glossogobius giuris, which generally occurs in lower reaches of the river.
