Usually, the fish in each sample are counted and weighed by 

 species. At intervals, all the individual fish in the sample are 

 measured to obtain length frequency information. Sample size is 

 usually one bushel although occasionally a two bushel sample is taken 

 so that adequate numbers of individual species are present for length 

 frequency information. It has been determined that a one bushel 

 sample is an adequate representation of any single vessel's load for all 

 species present that make up over 10% by weight of the catch. The 

 increase in sample reliability in a two bushel sample for species 

 composition by weight analyses does not justify the additional labor at 

 this time. For the purposes of this report, it is presumed that the 

 samples are sufficiently reliable to indicate the seasonal trends and 

 relative amounts of the different species landed within - 5% for all those 

 species representing 10% or more by weight of the catch. 



Those species present in quantities amounting to less than 10% 

 of the catch are not reliably sampled and the limits of confidence are 

 very broad. However, it is felt that the general picture presented is 

 more than accurate enough for the purposes of those interested in what 

 this fishery lands for reduction. An extended analysis of sample 

 reliability will be published later in connection with other studies. As 

 far as possible, only samples taken in 1957 were used. In some cases, 

 however, the breakdown was made with information based on samples 

 taken in 1955 and 1956. The tables are annotated accordingly. 



Samples taken at one port may be used in an analysis of 

 another port's landings; it is the fishing area that we are concerned 

 with when we take the sample. The port of landing obviously has no 

 significant effect on the species composition. 



POINT JUDITH LANDINGS 



To obtain as accurate figures as possible, the Pt. Judith landings 

 are broken down into three general groups by area: landings from the 

 No Man's area, landings from those local grounds with depths of less 

 than 25 fathoms and referred to as the inshore area, and landings from 

 local grounds with depths of greater than 25 fathoms and referred to as 

 the offshore area. Only 1957 sample data was used for the inshore and 

 offshore areas. For the No Man's breakdown, the data for the last three 

 years has been combined. There has been no significant changes in the 

 percentages from one year to the next in this particular area. Interview 

 information on the fishing grounds was available for over 90% of the 

 trips. The uninterviewed trips were assigned to one of the three areas 

 according to the distribution of interviewed trips.
