Objectives

1. To increase harvests from WA farm dams by providing farmers with: Population control method(s) which increase the proportion of yabbies of marketable weights
2. Quantified methods for reducing dam environmental factors limiting yabbie production and causing variation in dam productivity
3. a manual of methods for stocking and managing farm dams to increase harvest per dam

Summary

This report describes the results of an ex-post benefit cost analysis of the FRDC ­funded project 'Enhancement of yabby production from Western Australian farm dams' (Project No. 1994-075). The project was carried out by the Western Australian Marine Research Laboratories.

The main findings of the project were that stocking density, feeding and male:female ratios were the most important factors which influenced growth rates.

The research station trials also showed that growth rates improved when ponds were stocked with males only. The project investigated yabby "varieties" from around Australia to assess the potential of producing a male only strain or hybrid. A number of hybrids were produced which showed preliminary evidence of hybrid sterility. Further research was recommended which was funded by a subsequent FRDC project.
