Regrowth of pilchard (Sardinops sagax) stocks off southern WA following the mass mortality event of 1998/1999
This project produced time series of estimates of spawning biomass for pilchards in four purse seine management zones in Western Australia, three on the south coast and one on the west coast. The pilchard stocks in Western Australia have recovered strongly since the 1998/99 mass mortality.

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...

Management of bioeroding sponges in wild stocks of Pinctada maxima in Western Australia
Data on bioeroding sponge species that excavate shells of the pearl oyster, Pinctada maxima, was collected from the main fishing grounds in North Western Australia. Estimates on infestation rates across size/age classes of shell are provided from the main fishing grounds and over three consecutive...

Analysis of the microchemistry and stable isotopic composition of the otoliths of goldband snapper (Pristipomoides multidens) as an aid to the determination of stock structure
Measurement of stable isotope ratios of oxygen (18O:16O) and carbon (13C:12C) in the earstone (sagittal otolith) carbonate from assemblages of goldband snapper, Pristipomoides multidens, from waters off northern and western Australia revealed location-specific signatures and indicated that fish...

Management and monitoring of fish spawning aggregations within the West Coast Bio-region of Western Australia
Many strategies have evolved among fishes to maximise spawning success. One of the most striking of these is aggregation spawning, in which individuals group together, often at predictable times and locations in order to reproduce (cf. a school, which refers to a group of non-spawning fish)....
