Seaton, Secretary Fish and Wildlife Service, John L. Farley, Director SAURY DISTRIBUTION AND ABUNDANCE, PACIFIC COAST, 1950-55 by Elbert H. Ahlstrom Fishery Research Biologist and Harold D, Casey Fishery Aid Special Scientific Report- -Fisheries No. 190 Washington, D. C, November 1956 SAURY DISTRIBUTION AND ABUNDANCE, PACIFIC COAST, 1950-55 Information on the distribution and abundance of the saury, Cololnbis saira, in the eastern Pacific has been obtained on the monthly survey cruises of the California Cooperative Oceanic Fish- eries Investigations. The information is of tu-o kinds: (1) collec- tions of saury eggs in plankton hauls, and (2) visual observations of saury abundance. The California Cooperative Oceanic Fisheries Investigations are sponsored by the Marine Research Committee, and are carried out cooperatively by the South Pacific Fishery Investigations of the United States Fish and Wildlife Service, the Scripps Institution of Oceanography of the University of California, the Bureau of Marine Fisheries of the California Department of Fish and Game, the Hopkins Marine Station of Stanford University, and the California Academy of Sciences. The eggs of the saury are unique among planktonic fish eggs in CCOFI collections in that they frequently occur in clusters held together by adhesive filaments. The clusters of saury eggs taken in plankton hauls usually contain two to five eggs, and solitary eggs are as commonly taken in plankton hauls as are eggs in clusters. Occasionally, large clusters of eggs are found adhering to floating objects, or are taken in plankton collections. Hence, it is known that saury eggs do occur in large clusters. However, extensive frag- mentation of free-floating clusters must occur soon after spavining. Saury eggs occur so commonly in plankton collections that we consider them to be primarily pelagic eggs that can be sampled by quantitative plankton procedures. Records of saury eggs have not been reported previously. Data for six years, 1950 through 1955, are included in table 1. The num- bers given in the table are standard haul totals, hence are compar- able for all stations and years. Information concerning the plankton hauls is contained in the following series of reports: For 1950 (Staff of the South Pacific Fishery Investigations, 1954a); for 1951 (ibid, 1952); for 1952 (ibid, 1953); for 1953 (ibid, 1954b); for 1954 (ibid, 1955); and for 1955 (ibid, 195o). No analyses of the data will be given in this report. A manu- script is being prepared by the authors dealing with the distribution and abundance of the saury off the Pacific coast, based largely on the data presented herein. At the conimen cement of the ooeaiiographic-biological cruises of the California Cooperative Uccanic Fisheries Investigations, an inten- sive dip net program was carried out at night during occupancy of hydrographic stations. Fishes were attracted to a light source, such as the v.orldng lights of a research vessel or to a special light hung over the rail, and dip netted. It was soon noted tliat by far the most common species taken by dip netting was the saury. A range of sizes was obtained from recently hatched to mature adults, indicating that all sizes were positively phototropic. Because the sauries offer a potential fishery resource off our coast, and are already supporting a large fishery off Japan, it seemed desirable to obtain systematic observations of saury abundance at hydrographic stations. Such a pro- gram was initiated in September 1951, under the direction of Oi-ville P. Ball, then a staff member of the South Pacific Fishery Investigations, U. S. Fish and V.'ijdiife Service. Observations were made at all night stations, and records kept of saury abundance by size. Three size groups were distinguished: small, sauries under five inches in length; medium, sauries between five and ten inches in length; and large, sauries over ten inches long. Nine categories of abundance were adopted, as follows: A. Sauries absent, or not persistent under the lights. U - No sauries present, X - Sauries present, but not persistent under the lights. B. Sauries persistent under the lights. KK - Betv;een 1 and 5 present. R - Between 6 and 10 present. KG - Between 11 and 30 present. C - Between 31 and 100 present. VC - Between 101 and 500 present. A - Between 501 and 1000 present. VA - More than 1000 present. VJeighted numerical values have been assigned to the above cate- gories in order to obtain a rough estimate of relative abuadance. Categories that include less than 10 fisli (X, RR, and R) are rated 1, those that include between 10 and 100 fish (RC and C) are raLed 10, while categories having 101 to 1000 or more fish are rated lOn. Visual saury observations taken between September 1951 and Decem- ber 1955 are summarized in table 2, The tables list all night stations that were occupied, including stations at which no saury observations were made. The letter "N" is used to designate a night station at wliich saury obsei'vations i.'ore not made. Although this method of observation is only quasi-quantitative it does represent a practical approach for determining the distribu- tion and relative abundance of sauries in the area being surveyed on cruises of the CCOFI. The collections and observations at sea have been taken by a large number of individuals from the Scripps Institution of Oceanography of the University of California and the California Department of Fish and Game, as well as from the South Pacific Fishery Investigations. It is a pleasure to acknowledge the wholehearted cooperation of all par- ticipating agencies. Literature Cited Staff of the South Pacific Fishery Investigations 1952.
