Special Scientific Report; Fisheries No„ 73

This report contains data on the volume of zooplankton collected onthe monthly survey cruises of the California Cooperative Sardine ResearchProgram during 1951 o The cruises were numbered XXI through XXXII, Two

to four vessels participated in each cruise Participating vessels in-clude the Horizon (Cruises XXI, XXIII through XXVI, XXXII), the Crest(Cruises XXI through XXXI), and the Paolina T. (Cruises XXVII throughXXX) of the Scripps Institution of Oceanography j the N„ B, Scofield(Cruise XXI) and the Yellowfin (Cruises XXVI, XXXII) of the" CaliforniaDeDartment of Fish and Game, and the Black Douglas (Cruises XXII throughXXXI) of the U, S. Fish and' Wildlife Service.

The plankton samples are being collected for the twofold purposeof studying pilchard or sardine, Sardinops caerulea , "recruitment" and

the productivity of pilchard spawning areas „ The "recruitment 1* research

is being carried out by the U. S. Fish and Wildlife Service;; the pro-ductivity studies by the Scripps Institution of Oceanography. Rothfacets of the research are directed toward determining the factorsaffecting the survival rates of pilchard eggs and larvae.

The nets employed in collecting the plankton samples were constructedof No. 30xxx grit gauze, a heavy-duty grade of silk bolting clotho Theopening between meshes of this grade of grit gauze is approximately 0„65 mmThe nets were conical in shape, l o meter in diameter at the mouth byapproximately 5> meters in length,,

A similar procedure for taking plankton hauls was followed on allvessels. The hauls were made obliquely from approximately lUo metersdeep to the surface (200 meters of wire out at greatest depth) wheneverthe depth of water permitted,, Hauls taken at shallower depths are soindicated in the tables. At all stations, a current meter was used inthe mouth of the net to register the flow of water into the net

At a moderate number of stations, deeper tows were made in additionto the routine ones. Usually at such stations, 600 meters of wire waspayed out and retrieved. The data for such hauls are grouped togetheron the last page of the following tables.

In determining plankton volume, the plankton was separated from itspreserving liquid by filtering, allowed to drain, and then its volumewas determined by displacement. Consequently, the volume measured is"wet" volume

o

In the following tables the plankton volume is given under fourheadings s (1) Total displacement volume of plankton taken, (2) volumeof "smaller" organisms remaining when jelly masses, large mollusc a, fish,larger squid, and the like, were removed, (3) total volume standardisedin the amount present in 1000 cubic meters of water, and (a) a similarvalue for the smaller organisms.

Fcr each haul are given also the location, date and time of col-

lection, and volume of water strained in obtaining the haul. The volume

of water strained was determined from current meter readings for all

values except the few enclosed by parentheses, for which reliable current

meter data were lacking. For the latter, an approximate value was

obtained which represented the average performance of the current meter

at the speed at which the hauls in question were taken.

Inasmuch as plankton samples vary greatly in composition, a small

sample composed predominantly of crustacean plankton may actually repre-

sent more potential food material than a large sample composed largely

of jelly-like organisms, such as salps. This fact should be kept in

mind when using these data.

These investigations are part of the California Cooperative Sardine

Research Program, a program sponsored by the Marine Research Committee

and being carried out by the Scripps Institution of Oceanography, the

California Department of Fish and Game, the California Academy of Sciences,

the Hopkins Marine Station of Stanford University, and the South Pacific

Fishery Investigations of the U. S. Fish and Wildlife Service.
