Appendix 5 
Comparison of catch per unit of effort between day types 
Results from analysis in this study revealed a signifi- 
cant difference between weekday and weekend hook- 
and-line fishing in regions 1 and 2 (for location of 
these regions, see Appendix 1, Fig. 1). Comparisons of 
catch per unit of effort (CPUE) per day type for all 
regions combined and the gear types cast net, gill net, 
and snorkel spear did not show a significant difference 
(P>0.05) between weekday and weekend fishing. There 
were not enough data to compare weekday and week- 
end CPUE for the remaining gear types. 
Appendix 5 Table 
Comparison of catch per unit of effort (CPUE) per gear type between day types (weekday and weekend) with a 
Welch 2-sample t-test (which allows for unequal variances) and between regions with analysis of variance (ANOVA) 
for the hook-and-line fishery around Guam. Values are means (and standard deviations [SD] ) during 1985-2012. 
Region 0 is the combination of regions 1, 2, 3 and 4. Values of CPUE are given in kilograms per gear hour.
