Figure 7. Carapace length (CL) size frequency distributions for Biffarius arenosus collected at Warneet, Western Port in 2006-2007. Non-ovigerous females are shown by black bars, ovigerous females by grey bars and males by open bars (n = number of shrimp collected). Individuals are grouped into size classes by rounding to the closest mm from two decimal places. Arrows indicate mean CL of cohorts calculated in FISAT II.
