An industry based mark recapture program to provide stock assessment inputs for the Western Rock Lobster Fishery following introduction of quota management
The West Coast Lobster Managed Fishery (WCRLMF) moved from input to output controls in 2010. This change directly affected the relativity of a number of fisherybased data sources, making assessment of the fishery more problematic. A novel examination of the stock dynamics was required to help ensure...

Mitigation measures to reduce entanglements of migrating whales with commercial fishing gear
This project provided a robust assessment that gear modifications introduced into the WCRLMF
and octopus fisheries have reduced the number of reported entanglements. The management
arrangements around the implementation of these modifications are appropriate in light on the
new spatial and temporal...

Seafood CRC: decision-support tools for economic optimisation of western rocklobster
The Western Rocklobster fishery was one of the first to be made limited entry with the number of licences restricted since 1963. Historically, the main focus of the assessment and management of the fishery has been on the status of the breeding stock to ensure biological sustainability. In the...

BCA - Fishery-independent survey of the breeding stock and migration of the western rock lobster (Panulirus cygnus)

1. To use independent spawning stock survey techniques to validate spawning stock indices derived from commercial fisheries data and to examine specific impacts of the current management package over its full term. Specific impacts include trends in egg production and measurement of effective effort creep by comparison of fishery independent and fishery dependent spawninf stock indices.
2. To undertake pre-season tagging of juveniles in the shallow water of the limited entry fishery to obtain more detailed information on the migration and growth of these lobsters to aid in the understanding of the effects of distributing catch more evenly throughout the season.
Off-season trial of artificial rock lobster baits

SPECIES
1. There is a need to conduct trials of commercially available rock lobster baits:
A) To demonstrate that the industry is cognisant of the desire to reduce the dependence on imported frozen fish for bait.
B) To determine if a viable alternative to hides can found.
C) To do so well in time for the start of the season so that manufacturers of successfully trialled baits can produce bait to meet the expected demand at the start of the season.
1. To conduct statistically valid trials of three artificial rock lobster baits before the start of the 99-00 season.
2. To communicate the results of the trials to the industry before the start of the 99-00 season.

Assessing short-term movements of western rock lobsters by analysis of carbon and oxygen isotope ratios in their exoskeleton

SPECIES
Reporting of visible anchor tags by commercial fishers is believed to be biased in some circumstances. There is therefore a need to develop a fishery independent technique of identifying the origin of migrating whites lobsters so as to address the extent of movements of these animals between management zones, without having to rely on visible tags.
1. To investigate the factors affecting the carbon/oxygen isotope composition of the exoskeleton of western rock lobsters as a location specific chemical signatures for that species.
2. To apply these results as a method for determining the locality and depth (temperature) of a lobsters origin, at the time of its most recent moult.
