Need

The north west of Western Australia has productive commercial and recreational fisheries and extensive offshore oil and gas (O&G) infrastructure. These man-made structures support a range of demersal and pelagic fishes which are targeted by recreational and commercial fishers. As this O&G infrastructure reaches the end of its productive life, decisions on the best practice option for decommissioning must be made. The current policy for decommissioning requires complete removal. Regulators may support alternative strategies, such as leaving infrastructure in place, if risks and impacts are minimised and there are clear environmental, social and economic benefits to do so. It is thought that removal of infrastructure will decrease catch rates and have negative ecological, economic (direct and downstream) and social consequences.

At the same time as the discussion is occurring about removing O&G infrastructure, there have been large investments in constructing and installing purpose built man-made aquatic structures on the seafloor for the express purpose of enhancing the experience of recreational fishers and SCUBA divers.

There is a need to deliver critical information on: 1) the ecological, economic and social value of these man-made structures to recreational and commercial fishers and other stakeholders; 2) the attitudes of stakeholders to man-made structures; and 3) the opportunities and risks of decommissioning strategies to fishers and other groups (e.g. tourism).

Policy regarding the removal of decommissioned structures will benefit from the increased clarity that this project will provide in regards to data requirements for socio-economic models and stakeholder consultation methods. Comparative assessments of decommissioning options rely on the existence of appropriate socio-economic data, a knowledge gap this project aims to fill. An understanding of the impact of man-made aquatic structures on recreational and commercial fisheries is a global priority, and as such this project has strong international importance and relevance.

Objectives

1. To develop conceptual qualitative, semi-quantitative and quantitative models for describing the socio-economic values and decide what information is needed to give stakeholders an understanding of the value of manmade aquatic structures in the marine environment.
2. To collate a list and description of the manmade aquatic structures in the marine environment in Western Australian and the associated social, economic and biodiversity data.
3. To collect and collate data on four manmade aquatic structures in the marine environment and develop and compare the costs and benefits of qualitative, semi-quantitative and quantitative models.
4. To develop a decision support system or framework for undertaking socio-economic evaluations of manmade aquatic structures which can be used throughout Australia and guide end users on how to develop qualitative, semi-quantitative and quantitative models depending on their information requirements.

Summary

In 2018, the state’s recreational and commercial fishers (represented by the peak bodies Recfishwest and WAFIC) commissioned a program of research as part of a Fisheries Research Development Corporation project aimed at documenting the social and economic values and benefits that stakeholders obtain from MMS in Western Australia. These structures include shipwrecks, artificial reefs, break walls, structures associated with harbours, jetties, marine navigation markers, and O&G infrastructure such as platforms, wells, and pipelines.
During 2019 and 2020 the researchers undertook seven online surveys which focussed on understanding the social and economic benefits and values that recreational and commercial fishers, divers and other users gained from using MMS in Western Australia. This was complemented by eleven focus groups which included representatives from the commercial and recreational fishers, but also the Oil and Gas (O&G) sector, regulators (state and federal), conservation, non-government organisations (NGOs), scientific sectors, and the general community. The researchers used data to develop five case studies representing a range of different structures and end users. These case studies focussed on inshore Thevenard Island subsea O&G infrastructure (incorporating recreational fishing), Woodside’s Echo Yodel offshore subsea O&G infrastructure (incorporating commercial fishing), the Exmouth Integrated Artificial Reef (recreational fishing), the Exmouth Navy Pier (diving tourism), and the iconic Busselton Jetty in Southwestern Australia, which is used for tourism, by recreational fishers, divers, swimmers and many other stakeholders. A guidebook was produced outlining the different methods of identifying social and economic values, along with the types of data required, and the approaches to collecting this data. The guidebook also outlines the advantages, disadvantages and resource needs for each method. A database of the MMS in Western Australia was also compiled and made accessible online.

Need

There is widespread evidence, in Australia and internationally, of increased need for an improved, practical approach to integrated management (IM) of fisheries and other coastal marine activities that is able to fully embrace the social, economic and institutional aspects (the so-called ‘human dimensions), of management. Assessment and management systems traditionally neglect the human dimensions. Further, they treat sectors separately, often with different authorities managing diverse activities in different ways, resulting in inconsistencies in management across activities. The result is that there is almost no consideration of the cumulative social, economic or ecological impacts of multiple activities, and no way of informing trade-offs among activities in management decision-making.
Experience to date is that IM has been only partially successful. Management of multiple activities has been additive…squeezing one activity in among others (e.g aquaculture in light of others). While there are some examples of movement toward IM, these have resulted in partial or temporary success. There are examples where management has started toward IM, but progress has been stalled or has fallen back. In general, many preconditions exist, but it has been hypothesized that management is missing key aspects of intentional design that would allow IM to proceed.
The proposed workshop will bring together those with both the science knowledge and the operational knowledge of 8-10 Australian IM case studies and a few with international expertise, to evaluate and compare experience towards identifying key elements of success and failure of Integrated Management.

Objectives

1. Complete the creation of a lens for evaluation of Integrated Management that includes appropriate attention to social, cultural, economic, institutional as well as ecological aspects
2. Convene two workshops involving expert practitioners with sufficient scientific and operational knowledge of existing Australian Integrated Management case studies
3. Evaluate and compare experience on implementing IM in Australia using a single evaluative lens
4. Synthesize and report results of the evaluation and make recommendations for improved IM in Australia

Summary

Integrated management (IM) has been widely proposed, but difficult to achieve in practice, and there remains the need for evaluation of examples that illustrate the practical issues that contribute to IM success or failure. This paper synthesises experiences of academics and practitioners involved in seven Australian case studies in which there have been attempts to integrate or take a broader, holistic perspective of management. The evaluative framework of Stephenson et al. (2019a) was used as a lens to explore, through workshops and a questionnaire survey, the nine key features and five anticipated stages of IM in the Gladstone Harbour Project, the Great Barrier Reef, the Northern Prawn fishery and regional development, the South-East Queensland Healthy Waterways Partnership, the Australian Oceans Policy, the New South Wales Marine Estate reforms, and progress toward Integrated Management in the Spencer Gulf. Workshops involving experts with direct experience of the case studies revealed that most of the key features (recognition of the need; a shared vision for IM; appropriate legal and policy frameworks; effective process for appropriate stakeholder participation; comprehensive suite of objectives (ecological, social, cultural, economic and institutional); consideration of trade-offs and cumulative effects of multiple activities; flexibility to adapt to changing conditions; process for ongoing review, evaluation and refinement; and effective resourcing) were seen as important in all case studies. However, there are only a few examples where key features of IM were implemented ‘fully’. A subsequent questionnaire of participants using ‘best-worst’ scaling indicated that an appropriate legal and institutional framework is considered to have most influence on IM outcomes, and therefore is the most important of the key features. This is followed in salience by effective stakeholder participation, effective resourcing, capacity and tools, and recognition of the need for IM. Key features may change in relative importance at different stages in the trajectory of IM.

Need

Much effort has been placed over the last couple of decades on the development of harvest strategies, stock assessments, risk assessments and the strategic use of ecosystem models to facilitate meeting the needs of the Commonwealth’s Harvest Strategy Policy. A focus on modelling to improve fisheries management has required effort towards method development. However, little effort has been made towards revisiting and updating the biological parameters that fundamentally underpin such modelling (e.g. growth rates, age and size at maturity, natural mortality rates, dietary information, mixing rates and stock structure) and the tools or methods used to derive them. As a result, most models now rely on parameters and community dietary data derived from information collected during the 1970s-1990s, (e.g. available maturity ogives for blue-eye trevalla are over 20 years old), or information that is borrowed from other regions or species. Whether such old or borrowed values are now representative for commercial Australian fish species is unknown but many factors point to major changes occurring in our marine environment. Australian waters in the south east and south west are climate hotspots and, overall, Australian waters have warmed faster than the global average. Key components of the productivity of marine fish (growth, maturity, and recruitment) are expected to be undergoing directional changes under a changing climate and it is entirely possible that there have been changes in fundamental productivity parameters for some Australian stocks. The reliance of current assessments on what is likely to be out-of-date information leads to increased uncertainty, which propagates into management decisions. Without an understanding of any changes in biological parameters and how any change might impact assessment frameworks, determining whether current management measures are ensuring sustainability becomes highly uncertain.

Objectives

1. Identify the origin of current biological information used in assessments of species (including empirical stock assessments and ecosystem modelling efforts) carried out under the Commonwealth Harvest Strategy Policy, including the pedigree of the information (provenance, age, appropriateness of methods used).
2. Assess the implications and risks associated with using dated and borrowed information in assessments currently used for informing fisheries management, including the scale of any risks and the species for which a change in biological parameters used in assessments has the greatest impact.
3. Identify the methods that might be applied to update priority biological parameters, including a review of the efficacy and applicability of novel methods and approaches developed in recent years.
4. Articulate a work plan including appropriate sampling regimes required for updating priority biological parameters used in assessments for those species identified as being at most at risk.
