showed declines in numbers of fishers during the SEM while Mwanyaza and Mvuleni showed declines during the NEM. Based on the number of fishers per lunar day, the total number of manfishing-days per season and year can be calculated (Table 3). With an average of 42.25 and 27.30 fishers per day during the NEM and SEM respectively, we estimate that 1,225 and 792 fishers are active per lunar month, and 6,379 and 5,842 in each season. Using a global mean of 3.8 kg/fisher/day catch from the same dataset (Obura et al. 2002), these correspond to 24,240 kg and 22,201 kg of fish caught in the NEM and SEM respectively, and an annual catch for the Diani-Chale reef system of 46,442 kg. The above numbers give the average daily fishing effort. However fishers don’t fish every day, and we calculated a possible maximum number of fishers as follows: for each captain’s name, the maximum crew size was taken and added together to estimate a total number of fishers. Table 4 shows the numbers estimated by landing site and year. Overall, the numbers suggest a population of approximately 570 fishers in the Diani-Chale area. With 36.4-42.2 active fishers on average at each of the seven landing sites in the two seasons (Fig. 4), and therefore 252 – 294 fishers overall across the study sites, 45-52% of all potential fishers are active on any given day. :2&0)D"2) Spearguns were the most common gear used in both seasons, by 84 and 74 fishers in the NEM and SEM, respectively (Table 5) corresponding to > 30% of fishers among all sites combined, and slightly more in the main sites (Fig. 8). Beach seines, or juya, were the next most common gear (10-25%) due to their heavy -$(502)S!"6&*'()"$'"*K)+*()"',9
