Definition of effective spawning stocks of commercial tiger prawns in the NPF and king prawns in the eastern king prawn fishery: behaviour of post-larval prawns

To effectively manage most fisheries, including penaeid prawn fisheries in northern and eastern Australia, it is important to know the relationship between the size of the spawning population and the number of young adults that recruit to a fishery in the next generation. In the tiger prawn fishery...

Use of archival tags for studying the movement and swimming behaviour of school sharks

There has been serious concern over the status of the school shark fishery for many years, and it has been the subject of numerous stock assessments (Punt & Walker 1998). It is a well researched species: Olsen (1954) showed that school shark can make extensive migrations, and that females moved...

Mesoscale oceanographic data analysis and data assimilative modelling with application to Western Australian fisheries

The more that is understood about the factors controlling the abundance of an exploited fish stock, the more optimally it can be harvested for sustainable yield and profit. It has been known for some time that catches of western rock lobster are closely related to the number of larvae surviving...

IPA APFA: detection of pesticide impacts on larval prawns in hatcheries and presence in estuarine intake water

The use patterns of pesticides in Australia has changed over the last decade, with the use of pyrethroid and neonicotinoid insecticides increasing. The limited water quality data that is available has measured increased concentrations of the neonicotinoid insecticide imidacloprid in...

Improve catch rate standardizations to account for changes in targeting

In Australia many stock assessments are dependent upon catch-per-unit-effort (CPUE) to act as an index of relative abundance of fished stocks through time. But CPUE trends can be affected by many factors other than just stock size changes. Around Australia, and internationally, numerous and...

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...
