(1) To enable assessment reporting of trends in biomass and egg production by depth.
(2) To evaluate separate deep-water quota to increase yield and egg production.
(3) To evaluate regional size limits in Tasmania for increase in yield and egg production.
(4) To conduct field experiments and sampling to provide additional data required for alternative harvest strategy evaluation:
i. fisher catch sampling,
ii. translocation release survival,
iii. release movement,
iv. translocation growth transition,
v. effects of translocation on maturity and egg production parameters,
vi. density-dependent growth.
(5) To conduct field experiments on translocation to provide additional data required for economic evaluations:
i. change in colour,
ii. tail width,
iii. condition,
iv. survival in live transport.
 
(6) To evaluate translocation options that increase yield and egg production.
(7) To evaluate and compare spatial management options by economic analysis.
(8) To determine the extent of ecological community change in deep water reef habitats in response to increased harvest rates of lobsters.
(9) To develop functional management and monitoring recommendations to apply outcomes.

Objectives

0. To conduct field experiments and sampling to provide additional data required for alternative harvest strategy evaluation (fisher catch sampling, translocation release survival, release movement, translocation growth transition, effects of translocation on maturity and egg production parameters, density dependent growth).

1. To develop functional management and monitoring recommendations to apply outcomes.

2. To evaluate alternative spatial management options (deep-water quota, translocation, size limits) by economic analysis.

3. To conduct field experiments on translocation to provide additional data required for economic evaluation (change in colour, tail width, condition, and ability to survive transport).

4. To determine the extent of ecological community change in deep water reef habitats in response to increased harvest rates of lobsters.

5. To evaluate alternative spatial management options (deep-water quota, translocation, size limits) in respect to yield and egg production (biological projection).

6. To enable assessment reporting of trends in biomass and egg production by depth (model fitting).
