The data in this report are affected, however, by- 

 sampling errors and non- sampling biases of one kind or another. 

 Sampling errors especially affect estimates based on small 

 nijmbers as well as quantitative estimates of the pounds of 

 fishery products purchased, prices of fishery products, and 

 other quantitative data collected in the course of the survey. 

 Estimates of the sampling variability are given in the Appendix 

 of Volume I. A description of hovj the survey was conducted, 

 details of the survey design, and a copy of the questionnaire 

 are also available in that volume. 



The plan for the survey was developed in the Economics 

 and Cooperatives Marketing Section of the Branch of Commercial 

 Fisheries in the United States Fish and V.'ildlife Service under 

 the guidance of the late Chief of the Section, Dr. Richard A. 

 Kahn, and the Assistant Chief of the Section, Walter H. Stolting. 

 Both supervised the execution of the plan. The questionnaire 

 for the survey work was developed by Noriar Pahigian, Statis- 

 tician, in cooperation with the Bureau of Census, which collected 

 the data from a probability sample of establishments and pre- 

 pared the tabulations. Adolph Scolnick and Neil Newton, 

 Analytical Statisticians, supervised the preparation of the 

 report. Mrs. Evelyn Kramer, Statistical Assistant, and Donald 

 FitzGibbon, Commodity Industry Analyst, checked the final tabu- 

 lations and supervised the typing of all tables in the final 

 report. 



This report completes the analysis and presentation 

 of the data accumulated in this survey. The project was 

 financed with funds made available by the Saltonstall-Kennedy 

 Act, approved July 1, 195ii (68 Stat. 376).
