review
1. update descriptive analysis of toothfish fishery in the Ross Sea to 04/05
2. analyse age, LF and sex ratio for toothfish and rattails for 04/05
3. update and refine the CPUE for TOA in Ross Sea for 04/05
4. determine diet of sub-adult TOA in the Ross Sea
5. review the TOA parasite collection protocol
6. document TOA tagging protocol
7. review approaches to monitoring and assessing rattails and skates in the Ross
Sea
8. descriptive analysis of stake tagging programme in the Ross Sea
9. determine factors affecting bycatch of rattails and skates between vessels
10. carry out risk assessment for M. whitsoni and A. georgina in the Ross Sea
1. develop an effects of fishing model based around toothfish fishery
2. investigate possible consequences of different management strategies
3. make recommendations for future research to decrease uncertainty in the
model
2. To investigate the prediction of year class strength from environmental
variables.

1. To identify, discuss the effects and qualitatively assess the risks of
aquaculture and enhancement stocks improved by hatchery technology on New
Zealand’s wild fisheries resources and the marine environment.
2. To identify, discuss the effects and qualitatively assess the risks associated
with the translocation of aquaculture and enhancement stocks on New Zealand’s
wild fisheries resources and the marine environment.
3. To make recommendations on priority issues, risks, or research to be
undertaken, as a result of information discussed and evaluated in objectives 1-2.
Completed Speed 2005
1. To undertake a feasibility study on establishing an estimate of the mortality of
eels caused by hydroelectric turbines and other point sources of mortality caused
by human activity.
Completed Bentjees et al. 2005
Objectives unknown Completed Speed et al. 2006
1. To collate existing information on the role of beach-cast seaweed in coastal
ecosystems to assess the nature and extent of the impacts that the removal of
beach cast seaweed may have on the marine environment.
2. On the basis of the review in Specific Objective 1 above, to identify key
research gaps related to any marine environment impacts that the removal of
beach cast seaweed may have.
