Licensed to Kill: Can we use Quota Markets to Conserve Seabirds?

Creator:: Pascoe, Sean
Abstract:: Despite substantial technological developments over the last two decades, incidental catch of charismatic species still occurs in many world fisheries. Short of ceasing fishing activity, some bycatch is inevitable. In some cases, populations of these species are at low levels, and in several instances the species have been listed as...

Technical efficiency in the Victorian Abalone Fishery

Creator:: Mwebaze, Paul and Pascoe, Sean
Abstract:: The Abalone Fishery in one of Victoria’s most valuable commercial fisheries and most of the catch is exported to international markets in Asia (Japan, Hong Kong, Singapore, China). Target species consist of blacklip abalone and greenly abalone (<1% of total catch). The fishery is quota managed, and the total allowable...

Fisheries Management and Fisher Discount Rates

Creator:: Coglan, Louisa and Pascoe, Sean
Abstract:: Fishers are faced with multiple risks, including unpredictability of future catch rates, prices and costs. While the latter are largely beyond the control of fisheries managers, effective fisheries management should reduce uncertainty about future catches while also enhancing profitability. Different management instruments are likely to have different impacts on the...

Technical Efficiency of Culture-based Fisheries Production in Village Irrigation Systems of Sri Lanka

Creator:: Kularatne, Mohottola, Pascoe, Sean, and Wilson, Clevo
Abstract:: Despite the growing popularity of culture-based fisheries (CBFs) associated with village irrigation systems (VISs) in Sri Lanka, there is little knowledge about factors that influence productivity levels. To redress this, primary data from 325 fish farming groups in two districts (Kurunegala and Anuradhapura) are used to estimate a stochastic translog...

Offsetting Externalities in Estimating MEY in Multispecies Fisheries

Creator:: Pascoe, Sean, Hutton, Trevor, and Hoshino, Eriko
Abstract:: The Australian federal fisheries policy identifies maximising net economic returns as the primary objective of fisheries management. This has largely been interpreted as maximising the net economic yield (MEY) in fisheries. For multispecies fisheries, this has been based on maximising the net present value of total profit in the fishery...

Experiences with the use of bioeconomic models in the management of Australian fisheries

Creator:: Pascoe, Sean, Dichmont, Cathy, and Hutton, Trevor
Abstract:: Australian Commonwealth fisheries have adopted maximum economic yield as a target reference point. A bioeconomic model has been developed for one key fishery - the Northern Prawn Fishery - and is used in the provision of management advice. The development and application of this model has highlighted some challenges for...

Compensatory Mitigation: An Interim Solution to Seabird Bycatch in Fisheries?

Creator:: Pascoe, Sean, Wilcox, Chris, and Donlan, C. Josh
Abstract:: The concept of compensatory mitigation is well established as an approach to environmental management. In the past, mitigation programs have been used to conserve wetlands affected by development, and is proposed as a cost-effective approach to offsetting greenhouse gas emissions through reforestation programs. The concept may be equally applicable to...

Creator:: Hutton, Trevor, Thébaud, Olivier, Fulton, Beth, Pascoe, Sean, and Kulmala, Soile
Abstract:: A concern for the consequences of bycatch and discards in fisheries has led to the implementation of new policies and fisheries management plans aimed at their reduction in many fisheries around the world. Such plans have been developed for the Australian Commonwealth fisheries (the most recent bycatch action plan extends...

Impacts of Vessel Capacity Reduction Programs on Efficiency in Fisheries: the Case of Australia's Multispecies Northern Prawn Fishery

Creator:: Pascoe, Sean, Coglan, Louisa, Punt, Andre E., and Dichmont, Catherine M.
Abstract:: Capacity reduction programs in the form of buybacks or decommissioning programs have had relatively widespread application in fisheries in the US, Europe and Australia. A common criticism of such programs is that they remove the least efficient vessels first, resulting in an increase in average efficiency of the remaining fleet....

Proxy Measures for Economic Target Reference Points in Data Poor Multispecies Fisheries

Creator:: Pascoe, Sean, Hutton, Trevor, Thebaud, Olivier, Deng, Roy, Klaer, Neil, and Vieira, Simon
Abstract:: The Australian Harvest Strategy Policy requires that maximum economic yield (MEY) be the target in all Commonwealth managed fisheries. For multispecies fisheries, unlike single species fisheries, the optimal yield is not independent of the optimal yield of the companion species (i.e. those species with which it is caught). In fisheries...

Abstract:: With the development of the ecosystem approach to f isheries (EAF), fisheries management is increasingly required to deal with multiple, often conflicting objectives. In this context, the stochastic co-viability approach has been proposed as a useful modeling framework as it allows for the combined representation of complex fisherie s dynamics,...

Abstract:: Individual Transferable catch-Quotas (ITQs) have become a popular management tool to reduce excess competition and foster economic efficiency in marine commercial fisheries. They have increasingly been used in more complex multispecies fisheries, where the by-catch of non-targeted species is common. In these fisheries, the reduction of discards is also being...

Production Costs in Developing Fisheries Under Itqs: The New Zealand King Clam Fishery

Abstract:: Entrepreneurial New Zealand harvesters created a viable diving fishery for King Clams, Panopea zelandica, in the 1970's contributing to the development of allocation rights to harvest. Once under the quota management system (QMS), however, allocations for allowable catch do not reflect the harvest potential for this fishery. Expectations for quota...

The Effect of Quota Trading Limitation in A Fishery Managed Through Individual Transferable Quotas

Abstract:: Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to marine fisheries.
