Evaluating the effectiveness of marine protected areas as a fisheries management tool

Marine Protected Areas (MPAs) are being proclaimed around the world with the stated primary purposes of enhancing fisheries stocks and/or conserving marine biodiversity. In Australia, in response to a joint State/Commonwealth agreement to establish a National Representative System of MPAs (NRSMPA)...

Water use across a catchment and effects on estuarine health and productivity

This research has shown that the profitability of both agriculture on land and aquaculture in the estuary is affected by changing freshwater flows. To assess the value of water to different users across a catchment we developed a generic water accounting framework and populated it with available...

Workshop on post settlement processes affecting the southern rock lobster (Jasus edwardsii) in southern Australia

Research into the southern rock lobster in Australia has concentrated on the catching sector (primarily commercial) with limited research being undertaken on the post-settlement and juvenile stages. To maximise the outputs of investigating these stages, while at the same time minimising costs,...

Need

Knowledge of changing environmental conditions and productivity as a result of climate change is essential for adaptive management. In addition to direct applicability to fisheries and aquaculture in southern Tasmania, this information will have numerous important applications to other industries and stakeholders in the broader catchment.

CSIRO and TAFI have established a program (INFORMD- Inshore network for observation and regional management: Derwent-Huon) to guide multiple use coastal zone development and management. Storm Bay is an integral component of the INFORMD region and a priority is to understand both the short term (climate variability) and long-term (climate change) drivers of productivity in the region and link these to production of fisheries and aquaculture. CSIRO have a project investigating novel observing technologies (NOTe) to characterize the Derwent to shelf environment and TAFI will fund a charter vessel to monthly sample water column environmental variables, and support the CSIRO observing system. Thus an opportunity exists to obtain nutrient and productivity data in the Storm Bay region in a very cost-effective manner by collaborating with the existing research program.

Important background information is that the East Australian Current is predicted to penetrate further south causing significant warming and decreased productivity. Previous work (Harris et al 1991) showed that the nutrient status of waters clearly indicated the influence of the EAC, and primary producers indicated the productivity of the region, demonstrating the potential for Storm Bay to act as an indicator of productivity for Southern and Eastern Tasmania. Such information is important to understanding changes in fisheries and aquaculture production and, as a consequence, to assist with developing climate change adaptive management strategies.

This project also provides an opportunity for FRDC to invest in a project that will have significant influence on multiple use management in Australia.

Objectives

1. To provide information on the effects of a changing climate on water quality in Storm Bay and associated potential impacts on fisheries and aquaculture.
2. To collect nutrient and algal data from a targeted suite of sampling sites in Storm Bay to support sustainable development of the aquaculture industry.

Summary

This project has provided preliminary data on environmental conditions in Storm Bay that is assisting managers and marine industries to better understand effects of climate change and climate variability on fisheries and aquaculture in the region, including changing currents and primary productivity. This information is being used to inform the development of climate change adaptive management strategies for commercial and recreational fisheries and for the potential expansion of salmon aquaculture into Storm Bay. The environmental characterisation of Storm Bay is also supporting planning in the region, by providing baseline data and data for projects modelling the bay’s water circulation and ecosystem dynamics. This information will support the development of multiple use management plans for the region.

Keywords: Climate variability, Storm Bay, water quality, productivity, offshore salmon aquaculture

Rebuilding Ecosystem Resilience: assessment of management options to minimise formation of ‘barrens’ habitat by the long-spined sea urchin (Centrostephanus rodgersii) in Tasmania

By overgrazing seaweeds and sessile invertebrates, essentially back to bare rock, the advent of the long‐spined sea urchin Centrostephanus rodgersii in eastern Tasmanian waters poses a significant threat to the integrity, productivity and biodiversity of shallow (<40 m) rocky reef systems and the...

Pathogenic Vibrio parahaemolyticus in Australian oysters

This project was designed to produce a “snapshot” of the prevalence of the bacterium Vibrio parahaemolyticus in Australian oysters during March and April of 2002. V. parahaemolyticus occurs in two main forms: pathogenic and non-pathogenic. In the past 3 years there have been several...

Implementing a spatial assessment and decision process to improve fishery management outcomes using geo-referenced diver data

Fishing activity was captured across 53,852 one Hectare hex grid cells across Tasmania. A total of 113,164 diving hours were recorded across 125,536 individual fishing events (Table 1). Between 2012 and 2016, the Tasmanian Geo-Fishery Dependent Data (GFDD) program captured between 85 % and 90 % of...
