Stable isotope tracing of the contribution of seagrass production to subtropical fisheries species occurring outside seagrass areas

Results from this project affect the relative importance coastal managers will place on different estuarine habitats. Until now primary production from mangrove forests has been ranked highly for its presumed contribution to fisheries species occurring seaward of mangroves. This project...

Need

The estuaries of Australia’s tropical rivers support commercial fisheries for finfish, crustaceans and shellfish valued at over $220 million per annum. Development of water resources in Australia’s Tropical Rivers region is being considered for the Flinders, Mitchell, McArthur, Roper, Daly and Victoria catchments. The Northern Prawn Fishery also faces threats from land-based development, such as irrigation, and climate change, including changes to sea level. Given the well-documented correlation between flows and banana prawn recruitment, changes to river flows, nutrients, sediments and contaminant inputs are likely to affect fisheries yields (Loneragan and Bunn 1997; Robins et al. 2005). In order to tackle the effect of land-based development, CERF-funded TRACK will co-invest in research in the same river system. This would provide the means to undertake fisheries-targeted research in the wider context of environmental, social and economic research specifically on the Norman River and estuary adjacent to the banana fishery in the south-east Gulf of Carpentaria. This proposal therefore aims to determine how river flow affects estuarine prawn production and emigration. Via the partnership with TRACK, the implications of land use change on river flow, estuarine systems and ultimately prawn juveniles, will be assessed.

Objectives

1. Estimates of the impact of land use change on river flow, estuarine system productivity and ultimately prawn juvenile growth, survival and emigration
2. Identification of the mechanisms whereby the river flow regime affects banana prawn production and emigration from a river in the Gulf of Carpentaria, and how this impacts on recruitment to the fishery
3. Provide recommendations to water and fisheries managers on appropriate methods of assessing the effects of flows on estuarine prawn production

Water abstraction impacts on flow dependent fisheries species of the Northern Territory, Australia - a synthesis of current knowledge and future research needs

This project synthesised information that could be used to help guide decision making around the protection of fisheries species that may be impacted by water abstraction. This review was led by Griffith University and conducted in collaboration with the University of Western...
