Gut contents from all 12 stations combined for each month from March 1970 through March 1971. Over the shrimp size range evaluated, the relative amounts of detritus and diatoms differed markedly. Diatoms were more plentiful in small shrimp than in large ones. On the other hand, detritus was more abundant in the larger shrimp (Figure 3). Shrimp 16 to 17 mm long were excluded because only one of each was examined. Calculations for most of the other sizes were based on more than 80 individuals. The increase in percentage of detritus with size was rather uniform except for 2 mm shrimp (which included only 9 individuals). % lOOn SO- SO- 70 60 50- 40- iO\ 20 lOJ 0 lllllllllll DIATOMS â 1^ DETRITUS 5 6 7 8 9 SHRIMP SIZE IN MM 10 12 15 FIGURE 3.
