Estimating the abundance of School Shark in Australia using close kin genetic methods

Close kin mark recapture (CKMR) provides an estimate of absolute abundance that is independent of fishing behaviour. We present a first CKMR estimate of abundance for School Shark and discuss the management implications of our findings. We found 65 half sibling pairs (HSPs), 3...

A re-examination of underlying model assumptions and resulting abundance indices of the Fishery Independent Survey (FIS) in Australia’s SESSF

The model-based Fishery Independent Survey (FIS) for the Southern and Eastern Scalefish and Shark Fishery (SESSF) was developed in the lead up to the first survey in 2008 and is unique in a fisheries context in that it differs from a random stratified design, thereby allowing considerable...

Low cost management regimes for sustainable, small low-value fisheries based on coastal inshore species

This study provides a comprehensive, process-based guidance to developing low-cost management regimes for small-scale, low-value fisheries. The approach outlined is strongly “bottom-up” in that it seeks to identify pragmatic options and provide practical advice that specifically...

Maximising net economic returns from a multispecies fishery

Achieving fishery MEY may result in a reduction in net economic returns in a broader sense if the loss to consumers exceeds the gain to the industry. Such a loss may occur if supplies to the local market are reduced and prices paid by consumers increase. This results in a transfer of benefits from...

Next-generation Close-kin Mark Recapture: using SNPs to identify half-sibling pairs in Southern Bluefin Tuna and estimate abundance, mortality and selectivity

This report presents the results of the first application of Close-Kin Mark-Recapture (CKMR) using both Parent-Offspring Pairs (POP) and Half-sibling Pairs (HSP). This application to Southern Bluefin Tuna (SBT) has been successful, providing a decadal time series of absolute abundance, total...

Determination of the spatial dynamics and movement rates of the principal target species within the Eastern Tuna and Billfish Fishery and connectivity with the broader western and central Pacific Ocean – beyond tagging

Accessing samples from broadbill swordfish from two sites within the WCPFC area was particularly problematic and was exacerbated by a poor fishing season in 2019. This resulted in samples for broadbill swordfish consisting of samples collected from the ETBF (2 years), Norfolk Island (1 year) and New...

Demand Conditions and Dynamics in the Southern and Eastern Scalefish and Shark Fishery: Empirical Investigation

This final report, a collaboration between economists from CSIRO, CQU and ABARES, is the first detailed analysis of the interrelationship between fish prices on the Sydney and Melbourne fish markets. In addition, the study derived empirical estimates of the own and cross-price flexibilities for the...

Developing triple bottom line harvest strategies that include all environmental aspects for multi-sector fisheries

Based on the results of a comprehensive literature review and the collective expertise of the project team, we developed two alternative approaches with which to evaluate trade-offs between triple bottom line objectives and stakeholder preferences: a semi-quantitative multi-criteria decision...
