WASHINGTON COAST EXPLORATIONS: 



A total of 6 hauls, 5 with the modified -^-scale, 

 4-inch mesh trawl and one with the Standard 

 Mark II "Cobb" trawl was made off the Wash- 

 ington coast between Gray land and the Co- 

 lumbia River Lightship over average bottom 

 depths ranging from 23 to 74 fathoms. An- 

 chovy was the dominant species collected, fol- 

 lowed by silvergray rockfish ( Sebastodes 

 brevispinis ), yellowtail rockfish ( Sebas - 

 todes flavidus), starry flounder ( Plati- 

 chthys stellatus ), and dogfish ( Squ alu s 

 acanthias ). 



No echo traces indicating anchovy were 

 observed between the 10- and 140 -fathom iso- 

 baths from Cape Flattery to Grays Harbor 

 during the survey. The area between Grays 

 Harbor and Pacific Park showed an occasion- 

 al weak to fair echo trace over bottom rang- 

 ing from 19 to 41 fathoms. A total of 75 

 pounds of anchovy was collected from a 10- 

 minute tow off Grayland, on light scattered 

 traces ranging from 8 to 15 fathoms in depth 

 over an average bottom depth of 33 fathoms. 

 These fish ranged from 6 to 13 centimeters 

 (2.4 to 5.1 inches) and averaged 8.96 centi- 

 meters (3.5 inches) in length. 



The area between Pacific Park and the 

 Columbia River Lightship showed several 

 fair to excellent concentrations of anchovy - 

 like traces between the 12- and 74 -fathom 

 isobaths. Excellent echo traces showing sev- 

 eral concentrations of anchovy-like signs 

 were located throughout a 2|-- by li -mile area, 

 lying west of the Columbia River mouth over 

 bottom ranging from 21 to 35 fathoms. A 

 5,000-pound catch of anchovy was made in a 

 15 -minute tow on those traces, which ranged 

 from 18 to 32 fathoms in depth over an aver- 

 age bottom depth of 35 fathoms. These fish 

 ranged 10 to 18 centimeters (3.9 to 7.1 inch- 

 es) and averaged 14.15 centimeters (5.6 inch- 

 es) in length. Extreme gilling was observed 

 throughout the bag of the -l-scale |-inch mesh 

 trawl. Excessive gilling occurred again dur- 

 ing a 60 -minute tow off Peacock Spit. A total 

 of 3,000 pounds of anchovy was collected from 

 heavy echo traces ranging from 14 to 21 fath- 

 oms in depth over an average bottom depth of 

 23 fathoms. Anchovy ranged from 11 to 18 

 centimeters (4.3 to 7.1 inches) and averaged 

 15.03 centimeters (5.9 inches) in length. A 

 single 30 -minute tow, with the Standard Mark 

 II "Cobb" pelagic trawl, yielded 18,000pounds 

 of anchovy off Cape Disappointment. Heavy 

 echo traces ranged from 17 to 22 fathoms in 

 depth over an average bottom depth of 23 



fathoms. No gilling was observed during this 

 tow. No signs were observed between the 10- 

 and 50 -fathom isobaths south of the Columbia 

 River Lightship. 



COOPERATIVE STUDIES: In cooperation 

 with the Bureau's Seattle Technology Labora- 

 tory, about 7 tons of northern anchovy were 

 delivered to a commercial fish company in 

 Warrenton, Or eg., for experimental reduction 

 studies. Samples of anchovy were retained 

 and frozen from most hauls for proximate 

 composition studies by the Seattle Technology 

 Laboratory. Two tows with a 1 -meter plank- 

 ton net were made in Port Susan, Puget Sound, 

 for additional information on Pacific hake 

 studies presently being conducted by the Bu- 

 r.eau's Seattle Biolo g ical Lab oratory.

North Pacific Fisheries Investigations 



SALMON RESEARCH CRUISES 

 PLANNED FOR SUMMER 1966: 



The U. S. Department of the Interior's Bu- 

 reau of Commercial Fisheries Biological Lab- 

 oratory in Seattle, Wash., will send its re- 

 search vessel, the George B. Kelez , and two 

 chartered vessels to the North Pacific during 

 summer 1966 for research on salmon. The 

 Bureau's research vessel will fish a series 

 of stations south of Unalaska Island along 

 long. 167° W. Two chartered vessels, the 

 Paragon and St. Michael , are to fish stations 

 about 330 miles east and west of the George B. 

 Kelez at long. 176° W. south of Adak Island, 

 and at long. 158° W. south of the Shumagin Is- 

 lands.
