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...

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...
Consumer-facing traceability systems are emerging in the global seafood sector as a way for companies to reduce their reputational risk, access certain markets, and to generally communicate production practices to downstream actors. What are the characteristics of these systems, what benefits do they bring to different value chain actors, and...
To run the ITQ system as well as other components of the fisheries management system, the Icelandic government conducts a number of activities which may be regarded as fisheries management services. The most important of these are performed by (i) the Fisheries Directorate which maintains the quota registry and enforces...
Australian governments spend millions of dollars each year on pre-border, border and post-border biosecurity programs. The majority of these programs are resourced through existing deeds of agreement, but some currently fall outside of these funding frameworks. Frameworks not based on economic principles have the potential to deliver sub-optimal outcomes with...
When different species are caught together in mixed-fisheries but are managed under single-species management plans may lead to TACs of some species being exhausted before other. This leads to conservation and socio-economic problems in fisheries, where agreed harvest levels cannot be obtained for some stocks, while other stocks may be...
Various methods have been used to estimate the amount of above ground forest biomass across landscapes and to create biomass maps for specific stands or pixels across ownership or project areas. Without an accurate estimation method, land managers might end up with incorrect biomass estimate maps, which could lead them...
SUMMARY:
1. Understanding how predators select their prey can provide important insights into community structure and dynamics. However, the suite of prey species available to a predator is often spatially and temporally variable. As a result, species-specific selectivity data are of limited use for predicting novel predator–prey interactions because they...
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...
In 2007 the Fisheries Management Act passed through the South Australian parliament. The Act includes several new provisions which substantially changed the nature of commercial fishing rights, resource sharing between competing sectors and rights based management.

Lepidopteran nucleopolyhedroviruses are members of the Baculoviridae and have been categorized as having two morphotypes of occluded virions: multiple nucleocapsids or single nucleocapsids within the virion envelope. Although it is a definitive characteristic of specific viruses, it appears to lack a defined genetic basis and is independent of virus phylogeny....
Discard rates in marine fisheries have been estimated at more than 80% for some individual fisheries, with an average global discard rate of 8%. Discarding of catch can be problematic for three main reasons: (1) in the absence of accurate and precise discards estimates, unreliable catch data distort estimation of...
Tuna management in the Western and Central Pacific (WCP) is complicated given the dynamic and sometimes conflicting interests of participating countries and actors exploiting the tuna resource in the region. Pacific Island Countries (PICs) through the Fisheries Forum Agency (FFA) and the Parties to the Nauru Agreement (PNA) have developed a...
If the spatial and temporal distribution of resources is not homogenous it creates an assignment problem. While the adoption of individual (or transferable) quota management in many commercial fisheries has resolved issues of over-appropriation, assignment problems may remain due to the spatial and temporal complexity of fisheries resources, which creates...
In this paper, we discuss the solution for the shortage of labor supply in the fishing industry by comparing three countries/region in the East Asia; Japan, Taiwan and Korea.
