Completion of an analysis of stock structure of orange roughy, based on otolith chemical composition

Project number: 1996-111
Project Status:
Completed
Budget expenditure: $86,605.00
Principal Investigator: Ronald E. Thresher
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 8 Aug 1996 - 11 Aug 1999

Objectives

1. To complete a statistically valid evaluation of the stock structure of orange roughy in southern Australia, based on regional difference in otolith composition, by increasing sample sizes and coverage beyod that undertaken in a pilot study
2. To provide the results of analysis to industry, SETMAC and AFMA, for incorporation in management plans for the orange roughy fishery
3. To asses the utility of the otolith-based technique for other deepwater fished species such as oreo dories

A comparison of otolith microchemistry and genetic techniques for evaluation of stock structure of the jackass morwong Nemadactylus macropterus

Four different techniques for determining the stock structure of a marine fish species were compared, using as a subject the jackass morwong. The four techniques examined were allozyme analysis, mitochondrial DNA analysis and two techniques based on measuring the composition of otoliths ('ear...
