Fisheries and aquaculture management can have impacts on economic, social and environmental outcomes. Assessing alternative management options requires an understanding of the different trade-offs between these outcomes. Cost–benefit analysis provides a framework in which these trade-offs can be assessed, but requires all costs and benefits to be enumerated in monetary terms. However, some impacts associated with fisheries and aquaculture, particularly environmental, have no explicit monetary value, so they require non-market values to be derived. In this study, we identify and prioritize, through a stakeholder workshop, non-market values that are of the most relevance to Australian fisheries and aquaculture managers. We assess the potential of existing studies to provide appropriate values for use by managers through a detailed review of available studies. We found a deficiency in the number of recent studies across all priority areas. Non-market valuation of recreational fishing has attracted the most attention previously in Australia, but studies in the last five years were found in only half of the states. Other priority non-market values have been estimated in only one or two states, and most have no estimates within the last five years. The results of the study highlight the need for further research in this area.

Productivity and efficiency analysis have gained substantial attention in many industries over the last two decades, and stochastic frontier analysis has been one of the most popular analytical approaches. The abundant model choices in stochastic frontier analysis make it difficult to select the best option and compare studies. The main purpose of this study is to examine the sensitivity of technical and scale efficiency estimates to choices around input-output combinations, functional forms, distributional assumptions and estimation methods in stochastic frontier analysis, using data from an Australian fishery to illustrate these effects. We estimated 252 stochastic frontier models using combinations of variable choice, functional form and distributional assumptions. A second stage analysis was conducted to examine the effects of model choices on statistical properties of technical and scale efficiency. The results show that estimates of technical and scale efficiency are most sensitive to distributional assumptions and the choice of time effects. In particular, the assumption of time-invariant efficiency produced significantly higher technical efficiency (20 percentage points) and scale efficiency (8 percentage points) scores than time-varying efficiency models in our analysis. We also find that the choice of fixed input variables can significantly affect the average efficiency estimates, by as much as 5 percentage points, but mean efficiency was not significantly affected by the choice of variable inputs. Our findings suggest that caution should be taken when comparing findings of stochastic frontier studies using different distributional and fixed input assumptions.

The impact of the recent coronavirus pandemic on world seafood trade highlighted the vulnerability of the industry to international shocks and prompted calls for more diverse supply chains. In this paper, we assess the potential for increasing supplies of currently exported fish products to the local market using a Bayesian belief network model. Based on a survey of over 1000 Queensland residents, we determine the key drivers of consumption of locally produced fish and highlight the potential to engage in marketing strategies that bring the consumer closer to locally produced product (e.g. community supported fishery).

Understanding recruitment variability in marine fisheries has benefits for the stock management and dependent fishers’ ability to plan their income. Here, we overview past and new research on the complex recruitment dynamics of redleg banana prawns Penaeus indicus in Australia’s Joseph Bonaparte Gulf to assess themes dating back to the time of Hjort and identify new challenges. During 2015 and 2016, redleg prawn catches and catch per unit effort decreased to anomalously low levels, suggesting a substantial decrease in prawn biomass. We hypothesized that low catches could be explained by temporary drops in sea level and rainfall potentially reducing the ability of postlarvae to reach their nursery ground. We contend that very bad prawn catch years may be predicted using two variables that are possible drivers of recruitment—the January Southern Oscillation Index and the combined January to February cumulative rainfall. However, due to challenges in verifying and defining such environmental relationships for inclusion in a stock assessment, we propose development of a harvest strategy framework to support management recommendations. Our study highlights the increasing role of anthropogenic climate change in exaggerating the impacts of environmental drivers on recruitment processes and the need to also focus on multidisciplinary research.

Over the past 50 years, the diversity of fisheries types being actively managed has changed from mainly data-rich, industrial sectors to more socially, economically, and environmentally complex multispecies and multisector fisheries. Accompanying this change has been a broadening of management objectives to include social and economic considerations with traditional resource sustainability objectives, the so-called triple bottom line, and the need to include these considerations into harvest strategies. The case of a line fishery in Australia’s Great Barrier Reef is used as a demonstration of the first steps in implementing triple bottom line harvest strategies. This fishery has several disparate sectors including commercial, tourism, and recreation; targets multiple but important reef species; and is undertaken in a World Heritage Site. This work highlights the need for a much-expanded set of objectives elicited from stakeholders that are either included in the trade-off analyses of the different harvest strategies or directly in an optimization. Both options demonstrated that a paradigm shift is required to emphasize representative participatory management systems that assemble teams from quite different backgrounds and viewpoints; use much broader set of objectives; and modify tools and (especially) the data collected within revised monitoring programmes to underpin these tools.

Recent low levels of fishing effort in the redleg banana prawn (Penaeus indicus) component of the Australian Northern Prawn Fishery have highlighted challenges in assessing the stock status of the species and deriving appropriate management responses. Usually, low levels of fishing effort are associated with low stock abundance, but economic factors also affect fishing activity. In this study, we consider the key drivers of fishing effort in the sub-fishery, and conclude that fishing effort is driven by expectations of catch based on environmental drivers, realised revenue per unit of fishing effort, and the opportunity cost of fishing in other areas. In the case of the recent low effort levels, it is the opportunity cost that has been most influential, highlighting the importance of considering economic drivers when managing fisheries.

Fisheries management is characterised by multiple objectives, some of which may be complementary, while others may require trade‐offs between outcomes. Balancing these objectives is made more complex in the case of multispecies and multigear fisheries. In this paper, we develop a bioeconomic model that captures the key elements of such a fishery to test a range of potential harvest strategies to provide insights into how economic target reference points could lead to both desirable and undesirable management outcomes (e.g. discards). The model is developed as a long‐run optimisation model to identify target reference points to achieve multispecies maximum economic yield, and a dynamic recursive optimisation model, which includes more realistic representation of fishers’ behaviour, such as discards and trading of under‐caught species quotas. The potential economic, social and ecological impacts are evaluated using data envelopment analysis (DEA). The results suggest that the use of proxy target reference points can result in short‐term economic benefits at the cost of slower stock recovery and higher discarding. Limiting the number of species subject to quota controls may also prove beneficial in multispecies fisheries, while ensuring quota markets are efficient is likely to produce benefits irrespective of the harvest strategy adopted.

Rights-based management has been advocated as a means of improving the biological sustainability and economic performance of commercial fisheries. The most common forms of rights-based management implemented are individual transferable catch quotas (ITQs) and individual transferable effort quotas (ITEs). Perceptions of success of these management systems vary, however, with some being considered successful while others have been criticized, especially when broad social outcomes are taken into consideration. In this study, we develop a Bayesian belief network model that considers the underlying governance and social environment in which the fishery operates, along with the characteristics of the fishery. We use data derived from a survey of fishers, managers, and scientists to populate the model from 47 Australian fisheries currently managed through ITQs and ITEs. As well as capturing the characteristics of the fisheries, the survey asked respondents for their perceptions on the overall performance of the management system, as well as its performance against social, economic, environmental, and governance objectives. The results suggest that positive perceptions of management performance are related to the quality of social relationships between fishers, the efficiency in the functioning of quota markets, and the degree to which economic information is used in quota setting.

Transferable fishing rights in the form of individual transferable catch quota (ITQ) have been introduced into a large number of fisheries worldwide, mainly to achieve resource sustainability objectives and to improve the economic performance of the fisheries. ITQs have been credited with a number of potential benefits, particularly in relation to fisher incentives and allowing the fishery to adjust in response to changing biological and economic conditions without the need of further actions by managers to reduce fishing effort. While these economic benefits have been realised in some fisheries, others have seen less of an improvement in economic performance and believed to have resulted in adverse social impacts in some cases. This article reviews international experiences of ITQ management to determine the experiences elsewhere in relation to sustainability, economic, social, and governance outcomes, collating the empirical evidence for ITQs in achieving multiple objectives, and highlighting the research gaps.

While prawns are produced domestically, most prawns currently consumed in Australia are imported from Asia. Local producers are concerned that these imports are depressing prices for their product, and future growth in imports due to increased global supplies would reduce their viability. We examined the price integration of prawn products within the Australian market using the autoregressive distributed lag (ARDL) bounds testing method. A Dynamic Inverse Almost Ideal Demand System (IAIDS) was employed to derive own- and cross-price flexibilities and scale flexibilities for the three prawn categories to determine whether the supply of one prawn product had an impact on the price of the other prawn products. The results suggest there is no price integration between domestically produced prawns (wild-caught and aquaculture) and imported prawns, but strong price integration exists between domestically produced prawns. The findings of the demand analysis confirm this result.

Sea bass (Lates calcarifer) is a key aquaculture species in Malaysia, produced as part of a polyculture system in cages but predominantly as a single species in ponds. The production of sea bass in Malaysia has decreased substantially since 2015. Several studies suggest disease may be the main cause for such decline, but changing economic conditions may also have played a role in this decline. In this paper, we use Data Envelopment Analysis (DEA) to examine these issues as well as identify the key drivers of efficiency and capacity utilization in the grow-out finfish industry. Our results suggest that most farms are technically efficient, but many are operating at lower levels of capacity utilization. Socio-demographic factors appear to affect pond production but less so cage production. The results suggest that the reduced output of sea bass is largely in response to changed economic conditions (output and input prices).

The coastal and marine environment provides a wide range of ecosystem services, many of which may be impacted through coastal management. Incorporating these values into cost-benefit analysis to support decision making is hampered by the lack of existing appropriate measures. While studies can be undertaken by these agencies to collect the appropriate values, the number of different habitats that may need to be considered is greater than what could reasonably be included in traditional economic approaches. In this paper, we propose combining of a multi-criteria method, namely the Analytic Hierarchy Process (AHP), with choice experiments to develop estimates for a wide range of coastal and marine habitat values that can be used by local planners and coastal managers. We apply the approach to the coastal regions in New South Wales (NSW), Australia. Coastal residents were initially asked to express their preferences for protecting different coastal and marine habitats using AHP, from which a relative index of utility was derived. A choice experiment was also implemented, involving a hypothetical new coastal reserve in their area protecting different combinations of habitats and funded through an increase in their local council rates. We found that nearly 90 per cent of NSW coastal residents were willing to pay to support coastal protection. Relative values derived from the AHP were used to extrapolate the choice experiment results to provide estimates of non-market values for a wide range of coastal and marine habitats.

Beaches provide multiple recreational opportunities, such as swimming, surfing, fishing, walking or just enjoying being by the seaside. Most previous studies that have valued beach use have assumed a trip to the beach was a homogeneous activity. In this study, we estimate the non-market value of beach usage by New South Wales, Australia, residents using a travel cost modelling approach. Unlike previous studies, we develop the model based on the activities that visitors mostly undertake when visiting the beach, and allow for multiple activities to occur. We find that different uses of the beach attract different levels of consumer surplus. Activities such as surfing, fishing and swimming generate higher levels of consumer surplus than more passive activities such as just enjoying the natural environment. We also find that Sydney residents have different values to non-Sydney residents. From our analysis, a trip to the beach provides a base level of consumer surplus of around $10/trip for Sydney residents, with additional benefits derived from undertaking different activities. For example, surfing followed by a walk along the beach adds an additional $17 to the value of the visit. Understanding the pattern of use is therefore important when estimating the use values of beaches.

Improving economic performance of fisheries is a common management objective, but economic information in many fisheries is limited, restricting the degree to which economic performance can be monitored. For fisheries managed through individual transferable quotas (ITQs), there is a ready source of information that is often untapped by managers; namely information on quota lease and sales price. With this information, and also information on the landed price of the catch, managers can assess the level of industry confidence in the generation of future profits, an indication as to how fishing costs have changed over time and also the key drivers of economic performance in the fishery. The approach is applied to an Australian ITQ fishery – the NSW Lobster share management fishery – to illustrate the usefulness, as well as the limitations, of the approach. From the analysis, industry confidence in the fishery has increased substantially over time, indicated by the derived implicit discount rate. Using a profit decomposition approach, profitability has also increased substantially, and that this is largely driven by lower costs per unit of capture (which largely reflects the improved condition of the resource), but in some cases has been driven by external factors which have impacted on the price received. The case study illustrates the potential usefulness of quota trade data in assessing fishery economic performance when direct measures of fleet profitability are unavailable.

Vietnam's marine capture fisheries are open-access, and the increasing number of fishing boats has led to concerns about the sustainability of the industry. Information on the level of efficiency and its determinants can help inform appropriate regulations and policies that support sustainable fisheries. However, such management must also be sympathetic to the regional economic environment in which the fishers operate. In this paper, the level of technical efficiency and its determinants for trawl fishing vessels in Vietnam is estimated using stochastic frontier analysis. The empirical results suggest that the average technical efficiency of the surveyed fishermen is about 79%, suggesting potential room to improve performance. Several factors have been identified which affect technical efficiency, including the age of the vessel, skipper experience and age, distance from fishing ground, engine type and use of family members in the crew. Significant differences were also seen between regions, with technical efficiency seemingly affected by the opportunity cost of labour. Poorer regions with fewer alternative employment opportunities were also associated with lower average technical efficiency, reflecting the effects of greater capital and labour non-malleability in these areas.

Ecosystem based fisheries management (EBFM) provides a framework to achieve ecological, economic and social sustainability in fisheries. However, developing harvest strategies to achieve these multiple objectives is complex. This is even more so in multi-sector multi-species fisheries. In our study, we develop such harvest strategies for the multi-species Coral Reef Fin Fish Fishery (CRFFF) operating in the waters of Australia’s Great Barrier Reef. The fishery includes recreational, charter and commercial sectors, and is a provider of regional employment and supplier of seafood to both local and export markets. We convened a series of stakeholder workshops and conducted surveys to identify stakeholder objectives and priorities, as well as potential harvest strategy frameworks for the fishery. These potential harvest strategies were assessed against the objectives using a further qualitative impact survey. The analysis identified which frameworks were preferred by different stakeholder groups and why, taking into account the different objective priorities and tradeoffs in outcomes. The new feature of the work was to qualitatively determine which harvest strategies are perceived to best address triple bottom line objectives. The approach is therefore potentially applicable in other complex fisheries developing harvest strategies which, by design, strive to achieve ecological, economic and social sustainability.

Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is less knowledge about factors that influence productivity levels. CBFs compete with rice for access to water in the VIS, so maximizing the efficiency of CBFs is essential to ensure that the limited water resources are used most effectively. To address this, primary data from 325 fish farming groups were used to estimate a stochastic translog production frontier. Technical efficiency in these irrigation systems was found to be generally low, and substantially lower than that of other aquaculture production systems in other Asian countries. This suggests that production can be increased substantially with better management using existing technology and resources. Removing subsidies, improving consultation with extension officials and improving water user rights – in particular, the introduction of a transferable community quota system – were found to be key means for improving efficiency.

Review based experiences of oil-spill induced impacts on fisheries were used to develop a Bayesian Belief Network (BBN) to evaluate the potential economic consequences of a (hypothetical) oil spill in the Great Australian Bight, an area currently being explored by several major international oil companies. The model differs from most previous BBN analyses in that it also considers the relatively short term economic impacts of such a spill, encompassing market and fisher behaviour, as well as impacts on the stocks affected directly by the spill. The results suggest that impacts vary depending on the characteristics of the fishery (i.e. main species, location etc.) and the timing and extent of the oil spill, but market, management and fisher behavioural responses (and their ability to respond) were found to have the greatest impact on the final economic outcomes.
