Ichthyoplankton and Station Data for Surface (Manta) and Oblique (Bongo) Plankton Tows Taken During a Survey in the Eastern Tropical Pacific Ocean, July 30-December 9, 1998

摘要

This report provides ichthyoplankton, juvenile/adult fish, and associated station and tow data from surface and water column plankton samples collected during the 1998 Southwest Fisheries Science Center Stenella Population Abundance Monitoring (SPAM98) survey to the eastern tropical Pacific. It is the sixth in a series of reports that presents these data for all Southwest Fisheries Science marine mammal surveys in the eastern tropical Pacific from 1987 to the present. In total, 261 Manta net tows and 167 bongo net tows were taken between 30 July and 9 December, 1998, during which three research vessels surveyed within an area between approximately 30 degrees N and 18 degrees S latitude, from the Gulf of Panama westward to about 153 degrees W. The data are presented in 11 tables, and distributions of the 20 most frequently occurring larval fish taxa from each net tow type are shown in a series of figures. The background, methodology, and necessary interpretative information are given in an accompanying text.
