In 2009 the Fisheries Research and Development Corporation (FRDC) established the Social Sciences Research Coordination Program (SSRCP) to increase industry and government understanding and uses of social sciences in marine and fisheries management. Since that time a number of projects have been funded and promoted by the FRDC through the...
Since 2006, French quotas are shared out into annual catch entitlements per producer organizations (PO) according a stable allocation key. On this basis, PO’s have imposed catch shares to their own members but allocation and management rules are heterogeneous between PO’s. The objective of the paper is i) to assess...
In multi-species fisheries managed under ITQs, the existence of joint production may lead to complex catch-quota balancing issues. Previous modelling and experimental research suggest that, in such fisheries, some fishers may benefit from the ability to trade packages of fishing quotas, rather than fulfill their quota needs by simultaneously bidding...
Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...
This paper presents a new technique for shape and topology optimization of fluid channels using generative design synthesis methods. The proposed method uses the generative abilities of graph grammars with simulation and analysis power of conventional CFD methods.

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...
Individual transferable quotas (ITQs) have been used in several countries worldwide to regulate access to marine fisheries. While ITQs can improve the economic efficiency of fisheries, in practice their application rarely has the expected effects. In this study we compare the output predicted by an individual based model of quota...
As part of the ecosystem approach to managing fisheries and other uses of marine ecosystems, there has been a growing call for the development of integrated assessment tools to support the provision of both tactical and strategic management advice. Of particular importance in this domain is the development of models...
Can government regulations and company concerns to reduce their reputational and business risk lead to an increase in traceability programs? Are the drivers of traceability attributed to concerns over seafood sustainability, food provenance, quality and safety, fraud, and IUU fishing? These questions suggest there is a change in incentives and...
Within Indonesia and across the region the requirement for traceability within the seafood supply chain is limited to meeting the basic standard of HACCP, namely that the individual fish be traceable back to the 1st supplier, for quality sampling purposes. No common template for traceability exists and hence companies follow...
