Table 2
Total and relative distribution of estimated fishing effort (in h) by village and gear type in the study area. The extent of total fishing area and exclusive fishing area for each village (in km2) are indicated. The proportion of fishing area by village is estimated compared to the total fishing area (218 km2). The proportion of exclusive fishing area by village (%) is estimated compared to the total fishing area for each village. Numbers correspond to the villages with Ambohitsabo (1), Besakoa (2), Mahavatsy 2 (3), Ankiembe-bas (4), Mahavatsy 1 (5), Ankiembe-haut (6), Ankilibe (7), and Sarodrano (8).
