Figure 4. — Numbers of fish taken per hour of trawling 

 during shrimp fishing. South Carolina Outside and 

 Florida Outside, all species by months for all years 

 combined (see tables 2 and 5). Family Sciaenidae shown 

 for comparison. Broken lines are yearly averages. 



Outside, 983 per hour of trawling and 71 per- 

 cent of the catch. 



Fewer than 600 sciaenids were taken per 

 hour of trawling in February and March; the 

 number increased slowly during spring and 

 early summer, spurted to almost 1,300 in 

 July and August, continued to climb during 

 early fall, and peaked at 2,000 to 2,100 in 

 November and December; catches declined in 

 January and continued to the low in February 

 and March (fig, 6). 



The percentage of sciaenids in the monthly 

 average catches was lowest --60 to 61 percent-- 

 during February and March, increased during 

 spring, and reached and maintained a level 

 of 73 to 83 percent from July to January 

 (fig. 7). 



Carangidae . - -The yearly average catch of 

 jacks for the region was 89 per hour of 

 trawling, representing 5.4 percent of the total 

 catch. Catch per hour of trawling and percent- 

 age of the catch in different areas, ranked in 

 descending order of importance were: Florida

Figure 5. — Numbers of fish taken per hour of trawling 

 during shrimp fishing, Georgia Inside, Georgia Outside, 

 and Georgia Combined, all species by months for all 

 years combined (see tables 3, 4, and 6), Family 

 Sciaenidae shown for comparison. Broken lines are 

 yearly averages. 



Outside, 388 per hour and 14 percent of the 

 catch; Georgia Outside, 111 per hour and 8 

 percent; South Carolina Outside, 20 per hour 

 and about 1 percent; and Georgia Inside, 18 

 per hour and about 1 percent of the catch. 



Fewer than 10 carangids were taken per 

 hour of trawling in March and April; the 

 number increased rapidly and steadily through 

 the late spring, summer, and fall, to peak 

 at 287 in December, and then declined to about 

 126 in January and continued to the low in 

 March and April (fig. 6). 



Carangids contributed about 1 percent or 

 less of the monthly average catches in March 

 and April, increased during late spring, 

 reached and maintained a level of about 6 to 8 

 percent during late summer and fall, exceeded 

 10 percent in December, peaked at over 22 

 percent in January, declined abruptly in 

 February, and continued to the low in March 

 and April (fig. 7). 



Ariidae. --The yearly average catch of sea 

 catfishes for the region was 81 per hour of 

 trawling, representing 4.9 percent of the total 

 catch. They were most abundant in Florida
