Community structure, density and standing crop of fishes in a subtropical Australian mangrove area

Abstract

The fishes occurring in a subtropical mangrove (Avicennia marina) area in Moreton Bay, Australia, were studied for one year (November 1987 to November 1988, inclusive). Fishes within the mangroves were sampled using a block net, whilst those in adjacent waters were sampled using seine and gill nets. Forty six percent of the species, 75% of the number of fishes and 94% of the biomass taken during the study (all methods combined) were of direct importance to regional fisheries. The fish community utilising the habitat within the mangrove forest differed from that occurring in adjacent waters in terms of density, standing crop, species composition and diversity-index values. Standing-crop estimates for the fishes occurring within the mangroves (study period mean ± SD = 25.3 ± 20.4 g m−2) were amongst the highest recorded values for estuarine areas whilst those for adjacent waters (2.9±2.3 g m−2) were comparable to those of other estuarine studies.
