Analysis of variance in red sea urchin fishing effort and landings.

(a) Mean total effort (number of receipts) and total landings (thousands of kg) during 2009–2011 per management season (months with 4-day work weeks [limited access] and months with no management restrictions [unlimited access]) and region (14 CDFW blocks within the Channel Islands [CI] and the port of Fort Bragg [FB]), and one standard error (SE) are displayed. (b) Two-way ANOVA results testing the differences in commercial red sea urchin total effort and total landings, between management (mgmt.) seasons, and between the two regions.
