Abstract:

More than half of the fish biomass of coastal rocky reefs depends on zooplankton however the trophic basis of estuarine fish assemblages remains unknown We quantified the trophic basis i e basal energy sources of fish community biomass inhabiting three habitat types seagrass natural reef and artificial reef in two estuaries compared with two coastal rocky reef sites Fish assemblages were surveyed with Baited Remote Underwater Video BRUVs and the species abundance richness and biomass of fish were classified into nine functional feeding groups 6 teleost and 3 elasmobranch Comparable metrics for coastal fish assemblages were obtained from published surveys using BRUVs Using the functional feeding group biomass and the group specific diet composition the breakdown of energy sources was calculated using a food web analysis Estuarine reef habitats had different species and different functional feeding group composition than seagrass habitat The majority of fish biomass in the seagrass habitat was supported by detritus 51 in Botany Bay or macrophytes 58 in Lake Macquarie In contrast zooplankton supported most fish biomass 45 59 at the coastal reef locations and in reef habitat in one estuary 35 43 but not the other estuary 33 34 Trophic pathways which support fish assemblages are key in identifying mitigation measures which can help conserve these populations with growing urbanisation of estuaries and coasts 2022 The Author s under exclusive licence to Springer Verlag GmbH Germany part of Springer Nature
