Changes in population samples during the three-week removal program. The bars depict sequential male (A) and female (B) catches, with the 18 samples grouped in pairs. Hours spent collecting each pair of samples were : 2, 2, 2, , 4, , , 3 and 3, respectively. The dashed line in Figure 1A indicates a consistent decline in catch per unit effort starting midway through the removal program; the solid portion of each bar in Figure IB represents small females (females carapace length, the mean minimum size at onset of egg-bearing), while Figure ID illustrates the differences obtained in egg-bearing percentages for those larger females during.
