BCF PROVIDES INFORMATION TO TROPICAL TUNA FLEET Initial efforts toward extending BCF fish- ery advisory information to the tropical tuna fleet were completed during May, according to Dr. Michael Laurs, Group Leader, BCF La Jolla. Several San Diego-based purse seiners have sailed or are planning to sail to areas beyond the yellowfin regulatory area set up by the Inter-American Tropical Tuna Commission (IATTC).

BCF PROVIDES INFORMATION TO TROPICAL TUNA FLEET Initial efforts toward extending BCF fish- ery advisory information to the tropical tuna fleet were completed during May, according to Dr. Michael Laurs, Group Leader, BCF La Jolla. Several San Diego-based purse seiners have sailed or are planning to sail to areas beyond the yellowfin regulatory area set up by the Inter-American Tropical Tuna Commission (IATTC). One group of 6 or 7 vessels plans to fish as far west as Truk and Palau. For the most part, says BCF La Jolla, fishermen are unfamiliar with the oceano- graphic and fishing conditions they may expect tofind outside the traditional fishing grounds in the eastern tropical Pacific. The American Tunaboat Association (ATA) asked BCF to provide information on oceanography, weath- er, and tuna resources that may help fisher- men decide on areas most likely to have fish. Dr. Laurs Prepares Synopsis Dr. Laurs prepared a synopsis of what is known about tuna resources in the central and western tropical Pacific. It was based on records of exploratory cruises made mainly by BCF Hawaii and on Japanese catch data. "This information was included in a packet of data distributed to fishermen. The packet also included charts of sea-surface temper- ature, mixed layer depth, seabird and mam- mal sightings, information on weather, especially tropical storms, and sea condi- tions, and what weather advisory information is available over the marine radio bands for various regions in the central and western ; Also, arrangements were made with Tom Chase of Scripps Institution of Oceanography for BCF to print and distribute copies of un- published bathymetric charts containing the most up-to-date and complete information. Meet With Tunaboat Captains On May 10, Dr. Laurs and R. Green of BCF and F. Miller of IATTC met with about 15 tunaboat captains and A. Felando of ATA to brief them and to present the information gat
