内容記述
To clarify the number of fishing days a year in coral reef fishery, the author analyzed two fishing dairies of 2013 kept by two fishers (A and B) in Bise, Okinawa Island. The number of fishing days of fisher A was 187 days, and B 149. Both figures are exceeding the national average (122 days) of fishing boat with a gross tonnage of less than 1 ton in Japan. And two fishers’ numbers of fishing days in the summer season were more than those in the winter season. During the summer season, they went more frequently outside of reef, that is, reef slope (paa in the vernacular). During the winter season, on the other hand, they operated more frequently inside of reefs, lagoon (inou). Every morning fishers decide whether to go fishing or not, after checking the weather and the situation of the waves. The result of analysis of fishing dairies and daily wind velocities showed that fishers could not go fishing anywhere at a velocity of 9 m/s and over, and that they could operate everywhere (either in lagoon or reef slope) at a velocity under 3 m/s. Fisher A operated more frequently in the reef slope when wind velocity was under 3 m/s, while he operated more frequently in the lagoon when wind velocity exceeded 3 m/s.
