Seasonality of nutrient intake was evaluated by 7-successive-day food consumption survey in the ordinary season (March) and the slack season (June) of fish catch among 13 married couples in a Solomon Islands society, who were engaged in traditional horticulture and fishing, together with time allocation study. Males' time spent in gardening and fishing was significantly shorter in June than in March (gardening: -48 min/d, and fishing: -43 min/d; P<0 .05, respectively), while there was no seasonal difference in females. On the other hand, males spent more time in hunting and marketing, and females in particular did more time in marketing (P<0.01). No significant difference in energy intake between March and June was observed for either sex. The protein intake was significantly lower in June than in March (males: -23.9 g/d, P<0.01; females: -12.0 g/d, P<0.05). The males' fat intake was significantly higher in June than in March (+14.8 g/d, P<0.05), thought not significantly in females. To compensate the smaller amount of fish catch in June, the villagers spent more time in hunting and marketing, and they took larger amounts of coconut and a kind of nut, which abounds with fat . This study thus suggested that changes in food obtaining activities and food intake patterns of the villagers played significant roles to cope with seasonal shortage of fish catch.
