Fish habitats

Monitoring fish communities in nursery seascapes

This project aims to monitor fish communities in nursery seascape, using a range of underwater camera technology. This enhances our understanding of the role habitats play in fish abundance and size.

Featured project

Native fish are vital to Australian waterways. They support ecosystem health and serve recreational, commercial, and cultural needs.

We monitor fish habitats and species in both freshwater and marine environments. This research monitors fish populations, tracks invasive fish species and helps understand fish communities.

We are using environmental DNA to understand the distribution of fish species, allowing us to identify structures that act as barriers to fish migration.

Research, Monitoring

COMING SOON

We closely monitor coral reefs around Great Barrier Reef islands to understand their condition. We assess the impacts of disturbances such as cyclones, floods, and coral bleaching, and help track the patterns of recovery following these events.

April Hall

Senior Research Officer

April Hall is a senior research officer at TropWATER with broad interests in coral reef fish ecology and a particular focus on marine parks management and conservation of coral reef fish communities. April’s current research is centred on monitoring fish communities and associated benthic habitats on inshore fringing coral reef habitats of the Great Barrier Reef. April is a specialist in identifying and quantifying reef fishes, and is part of a team delivering a broad-scale integrated monitoring program for fishes on inshore reefs. In collaboration with the Great Barrier Reef Marine Park Authority, in 2022 April completed an Advance Queensland Postdoctoral Research Fellowship examining the contribution of partially protected conservation park (yellow) zones to biodiversity conservation in the Marine Park. This project built on her PhD research (2015) about the importance of predatory fishes on reefs and the trophic impacts of predator removals on coral reef fish communities. The fellowship provided novel data on the contribution of yellow zones to conservation and management of reef fishes on the Great Barrier Reef. April has worked collaboratively on a range of projects in Australia and the Indo-Pacific, including examining spatial and temporal trends in coral trout abundance, evaluating outcomes from locally managed marine reserves in Fiji and Solomon Islands, and investigating the demographics and reproductive biology of reef fishes.

Brendan Ebner

Senior Research Officer

Ebb is an ecologist with expertise in aquatic conservation. His primary interest is at the interface between society and aquatic fauna in freshwater and near shore marine ecosystems. He champions the application of direct observation and remote video for studying freshwater fishes and this has led to new insights into behaviour of rare and threatened species. This exploration has led to detection of species not previously known to occupy Australian waters and the conservation listing of species. Ebb provides key input to regional, state and national conservation planning in tropical Australia.

Eva McClure

Senior Research Officer

Eva McClure is a senior research officer at TropWATER, working with Dr Maya Srinivasan on the Great Barrier Reef Integrated Reef Fish Monitoring program. Eva’s role sees her surveying fish on inshore island reefs of the GBR and relating fish species abundance and distributions to reef condition and management zoning. She is particularly interested in fish species that have commercial and ecological importance, and how these species respond to their environment, including the effect of reef habitat change and fishing. Eva developed her experience as a fish ecologist at the University of Queensland, where she worked on a variety of projects as a research and field assistant. Topics included fish visual systems and the ecological influence of cleaner wrasse on coral reefs. Eva completed her PhD in 2019 with Prof. Garry Russ and Dr Andrew Hoey at James Cook University’s College of Science and Engineering and the ARC Centre of Excellence for Coral Reef Studies. Her research, based in the Philippines, investigated the relative influence of environmental and anthropogenic drivers on reef fish assemblages, such as disturbance to habitat, fishing and the spatial context of reefs. She was a Research Fellow at Griffith University from 2019-2020 with the Global Wetlands project, working broadly in wetland ecology and on projects using artificial intelligence to identify fish species from video. From 2021 Eva returned to JCU to work on a number of projects in the Coral Sea Marine Park with Prof. Andrew Hoey in CSE, where she currently holds a part-time position.
