Analysis of the distribution of pilchard eggs off WA to determine stock identity and monitor stock size

Project number: 1992-025
Project Status:
Completed
Budget expenditure: $216,042.54

Objectives

1. Document the distribution of eggs and larvae of pilchards along the entire south coast of WA during the critical winter season to determine the relationship between spawning at Esperance with the more eastern sites at Bremer Bay and Albany.
2. Determine the relationship between south and west coast pilchard stocks.
3. Examine interannual variation in the distribution and abundance of eggs in relation to changes in catch rates by the fishery and variations in the hydrological conditions particularly water temperature.
4. Provide data inputs on the distribution and abundance patterns of pilchards for the computer simulation model built to assess the state of the fishery.
5. Calculate spawning biomass estimates for the south coast using a modified egg production method
