Fisheries; Fish trade. 44 'Miller Freeman' Proves Fine Research Ship The new BCF research vessel Miller Freeman departed Seattle, Wash., in mid - February on cruise 68-02 (Feb. 12-Mar. 20, 1968). Primary objectives were to: monitor spawning of Pacific hake in California waters; determine the age, size, and sex composition of these hake stocks; and sample for changes in spawning habits of food and forage fish off the Washington coast. Eggs and larvae were collected at stations along the standard Washington transect (fig. 2) at the beginning and end of the cruise,

Fisheries; Fish trade. 44 'Miller Freeman' Proves Fine Research Ship The new BCF research vessel Miller Freeman departed Seattle, Wash., in mid - February on cruise 68-02 (Feb. 12-Mar. 20, 1968). Primary objectives were to: monitor spawning of Pacific hake in California waters; determine the age, size, and sex composition of these hake stocks; and sample for changes in spawning habits of food and forage fish off the Washington coast. Eggs and larvae were collected at stations along the standard Washington transect (fig. 2) at the beginning and end of the cruise, at 20 stations between San Francisco and Point Conception, Calif., and at 13 stations off southern California and northern Baja Cali- fornia. During the remainder of the cruise, the Miller Freeman conducted acoustic fish scouting and midwater trawling for adult hake. In attempts to locate schools of hake off southern California, the Miller Freeman op- erated in company with the Explo rat o ry Fishing and Gear Research vessel "John N. Cobb" and the chartered vessel "; Sampling With Net & Trawl Eggs and larvae were sampled with a 1- meter plankton net and adult hake with a |- scale Universal trawl (with l;f-inch mesh and -|-inch cod end liner). The trawling system also included pelagic hydrofoil-type otter doors, electric conductor towing cables, depth telemetry, echo-sounder, winches, stern ramp, and hydraulic gantry. Quantities of larvae of various species were taken off Washington, but eggs and larvae of hake were abundant only off southern California. Unfortunately, catches of adult hake were too small to permit analysis of the population features of the spawning stock. The satisfactory performance of the newly commissioned Miller Freeman and its unique midwater stern trawling system were re- warding. The experience gained by the crew and laboratory scientists led to the correc- tion of the observed shortcomings in the trawling equipment and proc
