Eight species of digenean parasite are described or redescribed from chaetodontid fishes from the southern Great Barrier Reef at Heron Island, Queensland. Six of these species belong to the Fellodistomidae: Symmetrovesicula chaetodontis (from Chaetodon aureofasciatus, C. bennetti, C. plebeius, C. rainfordi, C. speculum and C. trifosciatus), Paradiscogaster chaetodontis (from Chaetodon auriga, C, lineolatus, C. melannotus, C, plebeius, C. ulietensis and Heniochus chrysostomus), Paradiscogaster flindersi, sp. nov. (from Chaetodon ornatissimus [type-host], C. plebeius, C. rainfordi, C. trifascialis, C. trifasciatus and Heniochus varius), Paradiscogaster eniwetokensis (from Chaetodon aureofasciatus, C. baronessa, C. bennetti, C. flavirostris, C. ornatissimus, C. plebeius, C, rainfordi, C, speculum, C. trifascialis, C. ulietensis, C. unimaculatus, Chelmon rostratus and Heniochus varius), Paradiscogaster quasimodo, sp. nov. (from Chaetodon auriga, C. lineolatus, C. ulietensis and [?] C. ornatissimus) and Paradiscogaster glebulae, sp. nov. (from C. aureofasciatus C. bennetti, C. citrinellus, C. mertensii, C. ornatissimus, C. rainfordi, C. speculum, C. unimaculatus and Heniochus varius). The remaining two species belong to the Lepocreadiidae: Multitestis pyriformis (from Coradion chrysozonus) and Neohypocreadium dorsoporum (from Chaetodon aureofasciatus, C. auriga, C. flavirostris, C. kleinii, C. lineolatus, C. melannotus, C. pelewensis, C. plebeius, C. ulietensis, C. vagabundus, Heniochus chrysostomus and Parachaetodon ocellatus). The new combination Neohypocreadium chaetodoni (Madhavi, 1972) [originally in Preptetos] is made. A key to the species of Parodiscogaster is given.

Pearsonellum corventum, gen. et sp. nov., is described from the heart of Plectropomus leopardus (type host), Epinephelus quoyanus, E. merra, and E. ongus from the vicinity of Heron I. in the Great Barrier Reef. It has body spines in ventrolateral transverse rows, an X-shaped intestine with long posterior caeca, a single testis, a unique auxillary external seminal vesicle, a well-developed cirrus sac, a post-testicular ovary, a partly preovarian uterus, and a well-developed metraterm. Those characteristics support a closer relationship among many piscine blood fluke genera than indicated by the seven subfamilies recognised in Yamaguti's 'Synopsis of Digenetic Trematodes of Vertebrates'.

Coral Reef System

The Great Barrier Reef is the largest coral reef system in the world. It is recognised and appreciated worldwide as a unique environment and for this reason has been inscribed on the World Heritage List. The Reef is economically-important to Queensland and Australia, supporting substantial tourism and fishing industries. Management of the Great Barrier Reef to ensure conservation of its natural qualities in perpetuity is achieved through the establishment of the Great Barrier Reef Marine Park. The maintenance of water quality to protect the reef and the industries which depend on it is becoming an increasingly important management issue requiring better knowledge and possibly new standards of treatment and discharge.

Upper Slope

Data acquired during a winter (May) cruise of the RV Franklin to the southern Great Barrier Reef indicate that the dynamics of the shelf/slope region are governed by the tides, the poleward-flowing East Australian Current (EAC), and the complex topography. Over the Marion Plateau in water deeper than - 100 m, the EAC appears to drive a slow clockwise circulation. Tides appear to be primarily responsible for shelf/slope currents in the upper layers, with evidence of nutrient uplift from the upper slope to the outer shelf proper in the Capricorn Channel. Elsewhere, the bottom Ekrnan flux of the strongly poleward-flowing EAC enhances the sloping isotherms associated with the longshore geostrophic balance, pumping nutrient-rich waters from depth to the upper continental slope. Generally, shelf waters are cooler than oceanic waters as a consequence of surface heat loss by radiation. A combination of heat loss and evaporation from waters flowing in the shallows of the Great Sandy Strait appears to result in denser 'winter mangrove waters' exporting low-oxygen, high-nutrient waters onto the shelf both north and south of Fraser Island; these subsequently mix with shelf waters and finally flow offshore at - 100 m depth, just above the salinity-maximum layer, causing anomalous nutrient values in the region of Fraser Island.
