Ecological risk assessment for effects of fishing on habitats and communities

It is now widely recognized that fisheries can have impacts on marine species, habitats and ecosystems beyond the direct impacts of fishing on target species. For example, hundreds of species are regularly caught and discarded in many trawl and longline fisheries and in particular, interactions with...

Addressing knowledge gaps for studies of the effect of water resource development on the future of the Northern Prawn Fishery

Overview The objectives of this project were to use historical data and derived knowledge from banana prawn research in the Gulf of Carpentaria (GoC) to identify knowledge gaps and examine estuarine juvenile banana prawn abundance in a subset of Gulf estuaries where water development is...

ESD Reporting and Assessment Subprogram: review of the scope, assessment methods and management responses for fisheries ESD and EBFM in Australia

In 1997 the FRDC Board initiated a review of ESD application across jurisdictions (FRDC Project 98/168), and later worked with the Standing Committee on Fisheries and Aquaculture (SCFA) to develop a national approach to ESD in fisheries. Following on from this project, the FRDC Board suggested that...

Need

The Tasmanian salmonid industry has recently been faced with several significant production issues necessitating increased use of antibiotics and antifoulants. The effects of these chemicals on the local ecology and ecosystem function are currently poorly understood and without evidence to the contrary, it is difficult for the industry to refute the perception that such chemicals have a detrimental effect on the environment.

There is a large body of literature regarding the effects of antibiotics, however the information pertaining to aquaculture is limited. Improvements in husbandry and vaccine development have now all but eliminated the use of antibiotics in aquaculture overseas, consequently there have been few recent aquaculture specific studies, with even fewer studies on ecosystem effects, the available information largely focussing on environmental persistence and antibiotic resistance. However, there is quite a lot of information in the terrestrial livestock and medical areas on the comparative effects of various antibiotics as well as quite a substantial ecotoxicological literature. In contrast there is a substantial local literature on the environmental impacts of antifoulants and heavy metals. There is a need for a targeted review to establish environmental risk factors associated with current antibiotic and antifoulant usage and to develop an appropriate strategy to research and monitor ongoing impacts.

Some data on sediment residue levels for both antibiotics and antifoulants has been collected by the salmon industry in compliance with drug/chemical licensing permit conditions authorities and by the state government in response to concerns regarding antibiotic usage. So far this data has not been collated and has only been subjected to preliminary analysis; a comprehensive evaluation of this data would markedly improve our understanding of current impacts and help to determine what additional information may be required.

Objectives

1. Undertake a review of the international literature and current research to identify the existing state of knowledge regarding the environmental effects of antibiotics and antifoulants currently used or likely to be used in the Tasmanian salmonid farming industry.
2. Analyse local datasets on currently used antibiotics and antifoulants, collected in compliance with current licensing requirements, to determine what additional information is needed (if any) to appropriately evaluate the environmental impact of current management practices.
3. Develop an appropriate and cost effective research proposal to obtain the necessary information to evaluate the impact of current management strategies and design an appropriate ongoing monitoring programme.
