Sea Change: co-developing pathways to mitigate and adapt to a changing climate for fisheries and aquaculture in Australia
There is a need to increase effective engagement between fishing and aquaculture stakeholders and climate science and scientists in an ongoing strategic way, and not ‘just’ for single-project outcomes.
Improved engagement will help increase understanding of the likely implications of a changing climate in relevant contexts, and lay foundations for a shared exploration of available options for reducing risk exposure. We have worked with stakeholders and the FRDC Extension Officer Network to design a strategy that will engage fishing and aquaculture stakeholders on existing knowledge regarding risks and opportunities associated with a changing climate, to enable resource managers and researchers to better understand the ways in which many sectors are already adapting autonomously and to identify the barriers to further adaptation, and to co-design solutions that are relevant at local- and industry-levels to help build climate-ready communities and to stimulate economic resilience.
In many cases (but not all), extensive information regarding marine climate change - including key risks to fisheries and aquaculture producers (at a high level) - is already available, along with information on how to develop adaptation plans. However, despite this, progress and uptake within most sectors in terms of planned adaptation responses has been very slow – although many individual operators are already making ‘autonomous’ changes to their day-to-day operations in response to climate change drivers. If these changes are being made without access to best available knowledge, then it is very likely that substantial portions of these responses are maladaptive in the longer term, or may be countervailing to planned government adaptations (see Pecl et al 2019, Ambio, https://link.springer.com/article/10.1007/s13280-019-01186-x). This is a pattern evident within many different industries around Australia and across the rest of the world. ‘What’ needs to happen has thus been outlined in general terms in many cases, but such information is not co-developed or provided in consultation with end-users in ways that resonate or are useful to them. This project will address this need for relevance and usefulness.
The project aims to develop reflexive, ongoing, and two-way knowledge exchange between industry representatives, operators and manager, and the marine climate change impacts and adaptation research sector, so that solutions are co-designed, usable, and adoptable.

Tactical Research Fund: A review of the ecological impacts of selected antibiotics and antifoulants currently used in the Tasmanian salmonid farming industry and development of a research programme to evaluate the environmental impact of selected treatments.
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.
