At Heron Island reef, Great Barrier Reef Australia, biomass densities and mean wet mass of Ward's damselfish Pomacentrus wardi and the jewelled blenny Salarias fasciatus were not significantly different at 2-37 v. 2-95 g m(-2) and 8-7 v. 7-9 g, respectively. Whereas S. fasciatus significantly exceeded P. wardi in (1) total number of bites per day (3427 v. 1155), (2) the mass of epilithic algal community consumed per bite (2-19 1,. 0-14mg) and (3) total organic carbon consumed per day (487-31 v. 35-46 mg C m(-2) day(-1)). Territorial behaviour differed also between the two species. Pomacentrus wardi chased from their territories a smaller proportion of blennies than roving grazers (i.e. scarids, acanthurids, siganids and pomacentrids) relative to S. fasciatus. Salarias fasciatus chased c. 90% of other blennies from their territories, while chasing only c. 20% of all damsels that entered. Both P. wardi and S. fasciatus rarely chased non-grazers. The chasing behaviour of S. fascialus was size dependent, with resident fish chasing only individuals of its own family (i.e. Blenniidae) that were the same or smaller size. Pomacentrus wardi may have tolerated S. fasciatus grazing within its territory, as it contributes to territory defence from other blennies. The possibility that the interaction between the two species is facilitative, rather than competitive, is discussed. It was concluded that salariine blennies play an important, and previously underestimated role in coral reef trophodynamics. (C) 2004 The Fisheries Society of the British Isles.
Dietary analysis of the herbivorous hemiramphid Hyporhamphus regularis ardelio: an isotopic approach
Resumo:
The stable isotope values for a range of size classes of Hyporhamphus regularis ardelio from Moreton Bay, south-east Australia were determined. There was a positive linear relationship between 613 C and standard length (L-s) (delta(13)C = 0.034 Ls - 16-23; r(2) = 0.78). delta(13)C ranged from -8.48 to - 17.29 parts per thousand with the smallest size class (50 mm Ls) being on average 1.04 parts per thousand enriched with respect to that of zooplankton (Temora turbinata) and 7.97 parts per thousand depleted compared to Zostera capricorni. delta(13)C was positively correlated with Ls (P 0.0 1) with delta(15) N, ranging from 9.18 to 11.00 parts per thousand. Fish of all size classes were on average 2.32 and 7.63 parts per thousand more enriched than zooplankton and seagrass, respectively. Carbon isotope data indicate that H. r. ardelio commence life as carnivores and change to a diet in which seagrass is the primary carbon source. The dependence on animal matter, however, is always present. Due to the low percentage of nitrogen in Z. capricorni (2.5%) compared to zooplankton (9.1%) it appears that nitrogen from zooplankton is necessary throughout their life history with the carbon requirements for these fish coming chiefly from Z. capricorni.
