action to prevent overfishing because the lishery 

 and the bottomfish habitat are predominantly 

 within state waters. During the past 2 years, the 

 State ol Hawaii conducted a series of- meetings with 

 fishery managers, scientists, and fishermen to de- 

 velop a management plan for the state's bottomfish 

 fishery. In 1 998, the state established a new admin- 

 istrative rule that governs bottomfishing in state 

 waters and includes restrictions on fishing gear and 

 fishing areas. 



Progress 



Researchers continue to identify nursery habi- 

 tat for juvenile snappers and groupers in Hawaii, 

 and age and growth curves have been extended to 

 include early juvenile stages. Improvements have 

 been made in collection ot more complete catch- 

 and-effort data from the NWHI fishery. Fishery 

 discard patterns and interactions with sharks and 

 protected species have also been examined. 



No progress toward cooperative international 

 management is foreseen for the pelagic armorhead. 

 Cooperative exchanges of fishery data with scien- 

 tific colleagues in Japan have provided annual com- 

 mercial catch data by seamount. Recently acquired 

 biological data of importance for future manage- 

 ment considerations indicate that armorhead un-
