Figure •!.— Statistical areas along the Texas Coast. 

 By interviewing ilshermen, BCF employees are able 

 to record data on daily landings and fishing effort by 

 statistical area. The recording of catch and effort by 

 this method began in January 1956. Comparison of 

 this figure with figure 3 .shows that the relief plumes 

 lie in statistical area 19 and the lower portion of 18.
