Initial impacts of the COVID-19 pandemic on Australian fisheries production, research organisations and assessment: shocks, responses and implications for decision support and resilience.

Australia's fisheries have experience in responding individually to specific shocks to stock levels (for example, marine heatwaves, floods) and markets (for example, global financial crisis, food safety access barriers). The COVID-19 pandemic was, however, novel in triggering a series of systemic shocks and disruptions to the activities and operating conditions for all Australia's commercial fisheries sectors including those of the research agencies that provide the information needed for their sustainable management. While these disruptions have a single root cause-the public health impacts and containment responses to the COVID-19 pandemic-their transmission and effects have been varied. We examine both the impacts on Australian fisheries triggered by measures introduced by governments both internationally and domestically in response to the COVID-19 pandemic outbreak, and the countermeasures introduced to support continuity in fisheries and aquaculture production and supply chains. Impacts on fisheries production are identified by comparing annual and monthly catch data for Australia's commercial fisheries in 2020 with averages for the last 4-5 years. We combine this with a survey of the short-term disruption to and impacts on research organisations engaged in fisheries monitoring and assessment and the adaptive measures they deployed. The dominant impact identified was triggered by containment measures both within Australia and in export receiving countries which led to loss of export markets and domestic dine-in markets for live or fresh seafood. The most heavily impact fisheries included lobster and abalone (exported live) and specific finfishes (exported fresh or sold live domestically), which experienced short-term reductions in both production and price. At the same time, improved prices and demand for seafood sold into domestic retail channels were observed. The impacts observed were both a function of the disruptions due to the COVID-19 pandemic and the countermeasures and support programs introduced by various national and state-level governments across Australia to at least partly mitigate negative impacts on harvesting activities and supply chains. These included protecting fisheries activities from specific restrictive COVID-19 containment measures, pro-actively re-establishing freight links, supporting quota roll-overs, and introducing wage and businesses support packages. Fisheries research organisations were impacted to various degrees, largely determined by the extent to which their field monitoring activities were protected from specific restrictive COVID-19 containment measures by their state-level governments. Responses of these organisations included reducing fisheries dependent and independent data collection as required while developing strategies to continue to provide assessment services, including opportunistic innovations to harvest data from new data sources. Observed short run impacts of the COVID-19 pandemic outbreak has emphasised both the vulnerability of fisheries dependent on export markets, live or fresh markets, and long supply chains and the resilience of fisheries research programs. We suggest that further and more comprehensive analysis over a longer time period of the long-run impacts of subsequent waves of variants, extended pandemic containment measures, autonomous and planned adaptive responses would be beneficial for the development of more effective counter measures for when the next major external shock affects Australian fisheries.

The Global Pandemic Has Shown We Need an Action Plan for the Ocean

The urgency of the challenge requires an internationally coordinated effort that draws on existing global research capacity and networks;a key opportunity presented by the UN Decade of Ocean Science for Sustainable Development 2021-2030 (UNESCO-IOC, 2021) that must not be missed if we are to minimize change in ocean systems and impacts on the services they provide to society. Without mitigation and adaptation measures, sea level rise scenarios project annual losses of 0.3–9.3% of global GDP by 2100 (IPCC, 2019;equivalent to ~US$0.25 to US$7.88 trillion per year based on 2020 GDP, World Bank, 2021), while losses from declines in ocean health and services by 2050 are projected to be US$428 billion per year, and by 2100 US$1.979 trillion per year. Over the last decade, a number of programmes and projects have driven international efforts to develop the integration of human systems in global ocean ecosystem science, including the Integrated Marine Biosphere Research (IMBeR) project (Hofmann et al., 2015) to which the authors contribute. To help meet this challenge, the UN Decade of Ocean Science for Sustainable Development 2021-2030 (UNESCO-IOC, 2021) provides an opportunity to build global support systems for informing decision making on the critical time scales of the coming years and decades.

Publishing and peer reviewing as indicators of the impact of COVID-19 on the productivity of the aquatic science community

Beginning in February 2020, COVID-19-related stay at home orders and workplace shutdowns worldwide have disrupted personal and professional lives, including those of aquatic scientists. Manuscript submission and peer reviewing data from journals may be indicators of productivity impacts among aquatic scientists. We tested four null hypotheses: the COVID-19 disruption has had no effect on (i) the number of submissions to journals, or (ii) the geographic region in which the corresponding author is based, nor on the peer review process in terms of (iii) acceptance rate of requests to review and (iv) time in review. We used data provided by seven leading aquatic science journals covering the period 2009–2020 and representing 32 756 submissions. Submission differences varied between journals and were lower than expected in March 2020, but due to increases in subsequent months, there was no overall change in the number of submissions during the COVID-19 disruption months of February–June 2020. Geographic patterns in the number of submissions varied more by journal than by region, with both higher and lower numbers of submissions relative to expected numbers. Acceptance rates of requests to review were ∼2% lower overall;however, time in review declined by an average of 5 days relative to earlier years, showing that those scientists undertaking reviews did them more quickly during the COVID-19 disruption. Collectively, these results show that the overall productivity of the aquatic science community, as measured by publications and reviewing rates and times, has thus far only been slightly disrupted, although the impacts will vary greatly among individuals depending on life circumstances. The breadth and longevity of this disruption are unprecedented, making it important to continue to assess the relative impacts across a wide demographic range of aquatic scientists and to consider approaches to allow those differentially affected to recover to pre-COVID-19 levels of productivity.
