1. To establish a formal protocol for a length-frequency sampling survey which satisfies the two basic statistical criteria of accuracy and precision, specifically, (1) non-biased means, and (2) quantifiable variances.

2. To incorporate the desires of the fishing industry in the practicalities of length sampling, through extensive consultation and workshops, where fishers will ultimately decide the protocol adopted, while still conforming to the criteria of 1. above that assure the quality of survey information.

3. To assess the range of stock assessment methods available for analysing length frequencies to estimate the fundamental population dynamic parameters describing the South Australian lobster fishery, notably, annual recruitment, annual egg production, mortality, and size structure.
