“…Nonetheless, interdisciplinary collaborations and applying new emerging technologies are further needed to reduce regional knowledge gaps on the diet of fish species and further increase the resolution of our understanding of trophic interactions. Many biological disciplines beyond trophic ecology involve the collection of hundreds of fish individuals for life-history studies, genomic analyses and even parasitology studies (Cribb et al 2021), which could well be used for trophic analyses but are regularly discarded. Moreover, increasing the use of DNA analysis for trophic ecology in reef ecosystems can revolutionize the identification of prey groups to species level, allowing accurate assessments of ecological functions (Carreon-Martinez and Heath 2010).…”

Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles of many fish species and the importance of different prey groups for sustaining fish communities has, however, been limited by the historical classification of fishes into a few coarse trophic guilds. Using detailed diet information to perform a high-resolution trophic classification of 298 temperate reef fish species distributed across south-western Australia, we built a metacommunity trophic network to evaluate the most important trophic relationships and energy pathways. We identified 26 specialized trophic guilds within the broader groups of herbivores, zoobenthivores, zooplanktivores, piscivores and cleaners. Zoobenthivorous fishes had the highest species richness and trophic diversity with 191 species in 9 guilds. Micro-crustaceavores, decapodovores, mixed-crustaceavores, and crustacea-wormivores showed greater species richness and therefore redundancy at the metacommunity level. In contrast, a low redundancy of echinodermivores could represent a risk to local capacity for top-down control of sea-urchins across the region. Finer-scale analysis of prey at the family level showed that piscivorous guilds may influence different trophic pathways, with some consuming other piscivorous fishes, and others at lower trophic levels, particularly crustaceavores. Evidence of potential predation on herbivorous guilds was only found for turf grazers, suggesting that fish herbivory might not function as a significant energy-transfer link between primary producers and higher trophic levels. Among the prey consumed by fishes, micro-crustaceans and decapods accounted for 33% of all diet proportions. The importance of macrophytes to the fish community likely resides indirectly through the trophic pathway of herbivorous and detritivorous invertebrates, particularly crustaceans, which are much more highly consumed by fishes than macrophytes themselves. These higher resolution predator-prey interactions represent important steps in increasing our understanding of the blue-print of ecosystem functions in shallow marine systems. Identifying the specific trophic significance of different consumers and prey groups is crucial for ecological forecasting and the prioritization of conservation and resource management regulations in our current fast-changing world.

A new species, new host records and life cycle data for lepocreadiids (Digenea) of pomacentrid fishes from the Great Barrier Reef, Australia

A new species of lepocreadiid, Opechonoides opisthoporusn. sp., is described infecting 12 pomacentrid fish species from the Great Barrier Reef, Australia, with Abudefduf whitleyi Allen & Robertson as the type-host. This taxon differs from the only other known member of the genus, Opechonoides gure Yamaguti, 1940, in the sucker width ratio, cirrus-sac length, position of the testes, position of the pore of Laurer’s canal, and relative post-testicular distance. The new species exhibits stenoxenic host-specificity, infecting pomacentrids from seven genera: Abudefduf Forsskål, Amphiprion Bloch & Schneider, Neoglyphidodon Allen, Neopomacentrus Allen, Plectroglyphidodon Fowler & Ball, Pomacentrus Lacépède and Stegastes Jenyns. Phylogenetic analyses of 28S rDNA sequence data demonstrate that O. opisthoporusn. sp. forms a strongly supported clade with Prodistomum orientale (Layman, 1930) Bray & Gibson, 1990. The life cycle of this new species is partly elucidated on the basis of ITS2 rDNA sequence data; intermediate hosts are shown to be three species of Ctenophora. New host records and molecular data are reported for Lepocreadium oyabitcha Machida, 1984 and Lepotrema amblyglyphidodonis Bray, Cutmore & Cribb, 2018, and new molecular data are provided for Lepotrema acanthochromidis Bray, Cutmore & Cribb, 2018 and Lepotrema adlardi (Bray, Cribb & Barker, 1993) Bray & Cribb, 1996. Novel cox1 mtDNA sequence data showed intraspecific geographical structuring between Heron Island and Lizard Island for L. acanthochromidis but not for L. adlardi or O. opisthoporusn. sp.
