Economic losses due to diseases mostly caused by viruses remain a major obstacle to realizing the production potential of prawn aquaculture industries in many parts of the world. Broodstock used in prawn hatcheries in Australia are generally managed quite intensively and numbers used are generally...
Close kin mark recapture (CKMR) provides an estimate of absolute abundance that is independent of fishing behaviour. We present a first CKMR estimate of abundance for School Shark and discuss the management implications of our findings.
We found 65 half sibling pairs (HSPs), 3...
This project was developed in response to calls from the SBT Trilateral (now the CCSBT) Scientific Committee for the development and validation of techniques for the direct estimation of age and growth in the species. Since the early 1980’s, the stock assessment methods used by...
Prawn trawl fisheries are under increasing public and legislative pressure to manage their bycatch sustainably. Although this is now explicit in the fisheries management acts and the new Environment Protection and Biodiversity Conservation Act, there is little information on which to base sound...
Stock assessments provide scientific advice in support of fisheries decision making. They involve fitting population dynamics models to fishery and monitoring data to provide estimates of time-trajectories of biomass and fishing mortality in absolute terms and relative to biological reference...
One of the main objectives of fisheries management is to ensure the sustainability of fished stocks. To reach this objective scientists have to adequately assess the status of fished populations with quantitative models of the fishery systems. Most of these models require estimates of population...
