The Progress Report of the 1989Survey of the Research Project,"Man and the Environment in Papua New Guinea"COLLECTED FISH LARVAE AND JUVENILES IN THE WESTERNNORTH PACIFIC FROM NOVEMBER TO DECEMBER, 1989Futoshi KAKIZOE and Takakazu OZAWATo further our knowledge on fish larvae and juveniles in the western North Pacific,samples were collected using a larva net in an area from 12°06.rN to 28°40.5/N latitude andfrom 130°43.0'E to 141°23.8'E longitude. The larva net used was 1.6 m in diameter, 7.35 m longand had a 0.53 mm mesh size. Towing speed was 2 knots and a three layer step-tow (100, 150and 200 m wire out for each 10 minutes) method was used.Ten samples were collected with a total of 7,532 individual fish larvae and juvenileswhich were grouped into 128 species or types. In the list below, the scientific name is succeeded by the number of specimens, range of standard length (mm) and developmental stage(the latter two are in parentheses). Taxonomic category is divided by semicolon. Abbreviationsin the list: TN, total number of specimens; P, postlarval stage; M, metamorphosing stage; and J,juvenile stage.Station 1 26°51.r N 134°47.9' E Nov. 11, 23:58-00:50.
