COMMERCIAL FISHERIES REVIEW 



41 



Stations will be fished on each longitudinal 

 line to study the north-to-south distribution 

 of immature salmon south of the Aleutian Is- 

 lands and Alaskan Peninsula. Repeated fish- 

 ing at the various stations will yield data on 

 movement and changing characteristics (spe- 

 cies, age, origin, etc.) of salmon populations 

 in those areas with time. Fishing will con- 

 tinue from about July 1 until about September 

 1, 1966. Sampling gear will be surface gill 

 nets 1,400 to 1,500 fathoms long, consisting 

 of four mesh sizes--2|, 3^, 4j, and St inches 

 (stretched measure).

Primary objectives of the summer cruise 

 are to: 



(1) Determine the relative abundance, 

 north-to -south distribution, age composition, 

 and racial origin of immature salmon south 

 of the Alaska Peninsula and Aleutian Islands. 



This information may suggest more accurate 

 methods of forecasting runs of sockeye salm- 

 on in Bristol Bay, 



(2) Determine the percentage of captured 

 fish that drop out of high seas gill nets before 

 they are landed. Direct observation of salm- 

 on in the nets while the nets are fishing will 

 be attempted in order to establish the dropout 

 rate. 



(3) Compare catches from gill nets and 

 purse seines for information on selectivity of 

 both types of gear for certain species, sizes, 

 and ages of salmon. 



(4) Obtain oceanographic data to improve 

 understanding of the distribution and abun- 

 dance of salmon. 



This cruise will be the greatest effort in 

 personnel and vessels that the Bureau's Seat- 

 tle laboratory has expended in several years. 

 Detailed knowledge of the summer distribution 

 of immature salmon from areas south of the 

 Shumagin Islands as far west as Adak Island, 

 a distance of over 700 miles, is expected to be 

 gained from studies.

MANUFACTURERS INVITED TO EXHIBIT 

 PRODUCTS AT FRANKFURT, GERMANY: 



An opportunity for United States manufac- 

 turers to open outlets in Western Europe for 

 oceanographic instrumentation, equipment, 

 systems, and services was announced by the 

 U, S. Department of Commerce on April 12, 

 1966. The Department's Bureau of Interna- 

 tional Commerce (BIC) will give its first over- 

 seas exhibition of oceanographic products at 

 the U. S. Trade Center in Frankfurt, West 

 Germany, on November 2-9, 1966. United 

 States manufacturers are invited to show and 

 sell. 



A broad market development campaign is 

 underway to attract buyers, agents, and dis- 

 tributors to the exhibition from West Germany 

 and from neighboring countries of Western 

 Europe.
