Assessment of IUU fishing for Southern Bluefin Tuna
Autor: Tom Polacheck
Publikováno v: Marine Policy. 36:1150-1165
Illegal, unreported and unregulated (IUU) fishing is recognized as one of the largest threats to the sustainability of the world's fisheries. This paper focuses on IUU fishing in the context of unreported catches by members or co-operating non-member

Politics and independent scientific advice in RFMO processes: A case study of crossing boundaries
Autor: Tom Polacheck
Publikováno v: Marine Policy. 36:132-141
Provision of independent scientific advice is central to the operation of regional fisheries management organizations (RFMOs) even though RFMOs are largely policy (and political) instruments. Political pressures and intervention in science and crossi

Classifying tagging experiments for commercial fisheries into three fundamental types based on design, data requirements and estimable population parameters
Autor: J. Paige Eveson, Geoff M. Laslett, Tom Polacheck
Publikováno v: Fish and Fisheries. 11:133-148
Mark-recapture experiments have the potential to provide direct estimates of fundamental parameters required for fishery stock assessment and provision of subsequent management advice in fisheries. The literature on mark-recapture experiments is enor

A modelled cost‐benefit analysis of hybrid PIT and conventional tagging scenarios
Autor: Tom Polacheck, P Burch, Simon Wotherspoon, Stewart Frusher
Publikováno v: New Zealand Journal of Marine and Freshwater Research. 43:339-346
Tag recovery rate is an important parameter for estimating exploitation and natural mortality in fished populations. Passive integrated transponder (PIT) technology can record 100% of PIT tagged animals passing within the detection limit of a PIT tag

Consequences of assuming an incorrect error structure in von Bertalanffy growth models: a simulation study
Autor: Tom Polacheck, J. Paige Eveson, Geoff M. Laslett
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 64:602-617
The underlying sources of growth variability in a population cannot generally be known, so when modelling growth it is important to understand the consequences of assuming an incorrect error structure. In this study, four error models for a von Berta

Tuna longline catch rates in the Indian Ocean: Did industrial fishing result in a 90% rapid decline in the abundance of large predatory species?
Autor: Tom Polacheck
Publikováno v: Marine Policy. 30:470-482
Myers and Worm claim that their analyses of catch rates following the commencement of industrial longline fishing for tuna and billfishes show that these longline fisheries rapidly depleted the abundance of these large oceanic predators by 90% (Myers

Integrating catch-at-age and multiyear tagging data: a combined Brownie and Petersen estimation approach in a fishery context
Autor: William S. Hearn, Kenneth H. Pollock, Geoff M. Laslett, Tom Polacheck, J. Paige Eveson
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 63:534-548
A comprehensive framework for modelling data from multiyear tagging experiments in a fishery context is presented that incorporates catch data into the traditional Brownie tag–recapture model. Incorporation of catch data not only allows for improved

Sea turtle by-catch in pelagic longline sets off southern Brazil
Autor: M.C Pinedo, Tom Polacheck
Publikováno v: Biological Conservation. 119:335-339
Results are presented on sea turtle by-catch observed in pelagic longline sets during research cruises in the south Atlantic in the vicinity of the shelf edge break in southern Brazil. The longline gear was set in a similar manner to that employed by

An integrated model for growth incorporating tag–recapture, length–frequency, and direct aging data
Autor: J. Paige Eveson, Tom Polacheck, Geoff M. Laslett
Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 61:292-306
A maximum likelihood method for modelling fish growth is presented that integrates data from three key sources of growth information: tag–recapture studies, length–frequency samples from commercial catches, and direct aging data from hard-parts ana
