Table 2. Summary of fixed factors and Wald F-values in parsimonious generalised linear mixed models explaining variability in the catchability of Scylla serrata and numbers of Acanthopagrus australis among four treatment traps (51-mm conventional, 51-mm escape-gap, 101-mm conventional and101-mm escape-gap traps), and subsequent damage to S. serrata and when this occurred (during trap removal or measuring).
