Concerns about declines in marine biodiversity led to the creation of marine protected areas and spatial fishery closures as tools for recovery. Yet many marine conservation areas suffer low levels of compliance from diverse fishing populations, including recreational fishers. Little research quantifies levels of recreational fisher compliance and its drivers, especially in temperate marine environments, despite the prevalence of this kind of fishing in some regions. This thesis addresses this knowledge gap through a study of recreational fisher compliance in Rockfish Conservation Areas (RCAs) in British Columbia, Canada. One hundred and sixty four RCAs were implemented between 2003 and 2007 and now cover 4847.2 km2. These conservation areas were created in response to widespread concern from fishers and non-governmental organizations about inshore rockfish population declines. However, recent research suggested that recreational fisher compliance might be low. This thesis had two goals: 1) contribute to knowledge about, and develop methods of assessing, non-compliance within marine conservation areas, and 2) address the immediate problem of suspected recreational non-compliance in RCAs. I had the following objectives: 1) Assess ecological and social RCA effectiveness to date, using a framework for improving governance from the literature on common pool resources; 2) Assess recreational fisher knowledge and perceptions of RCAs, and 3) Quantify non-compliance and social and ecological compliance drivers in RCAs. Methods included a literature review, structured surveys with 325 recreational fishers at 16 locations in the Salish Sea (Southern Gulf Islands and Victoria area), and trail camera monitoring in 42 coastal locations (both RCAs and unprotected sites). Results show that recreational fisher knowledge and compliance to RCA regulations is low. The assessment of social and ecological effectiveness shows much room for management improvement for recreational fisheries. This finding is supported by my survey and trail camera data. I found that 25.5% of recreational fishers had never heard of RCAs and ~60% were unsure of RCA locations. The total non-compliance rate was 23% in RCAs. Seventy nine percent of trail camera monitored RCA sites showed confirmed or probable fishing activity, with no significant difference between fishing effort inside and outside RCAs. However, 77% of fishers surveyed believed that rockfish conservation is necessary with advertising, fisher education, and increased monitoring offered as solutions to non-compliance. I recommend managers implement a public outreach and education campaign to address low levels of compliance. This study suggests that positive perceptions of marine conservation areas and conservation initiatives are not enough to create high compliance. Educating stakeholders and creating high levels of awareness should be an essential first step when creating marine conservation areas. My research offers important insights into the study of non-compliance, and the immediate problem of recreational non-compliance in BC’s RCAs. My successful use of a simple and cost/time efficient multiple methods approach to assessing compliance provides robust tools for future compliance analyses, and hence provides a valuable contribution to the compliance literature. The study also suggests that trail camera monitoring could be a promising new method for monitoring coastal conservation areas. / Graduate / 0768 / 0792 / 0306

Precise and accurate species abundance and distribution data are important for making effective ecological conservation and management decisions. These data are often challenging to obtain, especially in marine environments where the logistical and technical difficulties of working underwater can limit the precision and accuracy of detection. The chosen survey methodology, along with the study design, will determine the extent to which species’ spatial or temporal variability in abundance and distribution may be investigated. Different observational methods may yield different results. I explore how the methodology used to collect sample measurements of fish abundance and diversity in marine environments can influence your understanding of the focal population and the effectiveness of spatial marine conservation measures. I compare inshore rockfish abundance and fish diversity estimates between paired towed video and baited video surveys and between dive and baited video surveys conducted on temperate rocky-reefs in the nearshore Northeast Pacific on the coast of British Columbia, Canada. I test if the baited video survey data yield equivalent insight to those data derived from the methods commonly used in shallow (dive surveys) and deeper waters (towed video surveys). Paired dive and baited video surveys took place inside and outside of spatial marine conservation areas designated for inshore rockfish called Rockfish Conservation Areas. I test whether the baited video data generate the same conclusions about Rockfish Conservation Area effectiveness as data derived from the dive surveys, and whether the Rockfish Conservation Areas have greater inshore rockfish abundance and fish diversity than paired locations outside the conservation areas. I find similar inshore rockfish abundance estimates between towed and baited video, but baited video surveys detect a greater number of unique species than the towed video surveys. The dive surveys detect greater inshore rockfish abundance and fish diversity than the baited video surveys, but the baited video data yield equivalent insight on Rockfish Conservation Area effectiveness to data derived from the dive surveys. I find little evidence that inshore rockfish recovery is influenced by Rockfish Conservation Area protection. When data were combined across all sites sampled, Rockfish Conservation Areas did not produce more inshore rockfish, bigger rockfish, or greater fish diversity than paired sites outside of Rockfish Conservation Areas, whether measured using a dive survey or a baited video survey. However, I did observe a positive effect of Rockfish Conservation Area protection for some of the individual Rockfish Conservation Areas surveyed that rated as having a high Conservation Score. This suggests certain Rockfish Conservation Areas may be effective conservation areas for inshore rockfish recovery. The differences I observe in inshore rockfish abundance and fish diversity between the paired surveys reveals the methodology used can influence species abundance and diversity estimates. Baited video surveys are a low cost and effort methodology that can be used to examine inshore rockfish abundance and fish diversity over rocky reefs from nearshore waters down to depths greater than 20 m, and to monitor the effectiveness of spatial marine conservation areas. / Graduate
