tively). This could be accomplished within practical 

 time limits (3-5 days) by using a large research ves- 

 sel with two auxiliary small craft. If specimens are 

 not needed — e.g. for age-growth studies — the video 

 assembly described seems to be an ideal sampling tech- 

 nique for obtaining an index of abundance for compari- 

 sons between different areas or between different times, 

 or between both. Additionally, video cameras can pro- 

 vide important, new information on habitat and be- 

 havior of juvenile opakapaka and associated species, 

 an important aspect of our continuing research. 



Acknowledgments 



We would especially like to thank F. Parrish for de- 

 velopment of a working video prototype and other 

 assistance, S. Ellis for assistance in the 

 reconfiguration of the video camera assembly, P. 

 Shiota for assistance in modifying Kali longline gear, 

 K. Landgraf for his help in the field with video gear, 

 P. Shiota, T. Kazama, and D. Kobayashi for collect- 

 ing longline sample data, and D. Yamaguchi for 

 graphic assistance with Figure 2. We would also like 

 to thank the officers and crew of the NOAA ship 

 Townsend Cromwell for their assistance and coop- 

 eration during collection of data and R. Moffitt, W. 

 Haight, S. H. Kramer, J. Parrish, and two anony- 

 mous reviewers for their helpful comments on the 

 manuscript.
