Biological Survey of Marine Communities around Triangular Island (Shoalwater Bay, Queensland),

Abstract

Marine communities around Triangular Island in Shoalwater Bay, Queensland were surveyed to provide data from which the effects of Naval training activities in the area could be assessed. The abundance and taxonomic composition of fishes, zooplankton, benthic flora and benthic infauna were determined off three beaches around the island. The composition of benthic communities depended on the tidal height and particle size of the substrate and groups of species characteristic of the different beaches were recognised. Invertebrates were more numerous in fine sediments. The biomass and diversity of fishes were generally higher, and zooplankton concentrations lower, over the northern mudflat than off the other two beaches. (Author)
