Across West and Central Africa, wildlife provides a source of food and income. We investigated the relation between bushmeat hunting and household wealth and protein consumption in 2 rural communities in Bioko Island, Equatorial Guinea. One village was dedicated to commercial hunting, the other trapped game primarily for food. We tested whether commercial-hunter households were nutritionally advantaged over subsistence-hunter households due to their higher income from the bushmeat trade and greater access to wild-animal protein. We conducted bushmeat-offtake surveys in both villages (captures by hunters and carcasses arriving to each village). Mammals (including threatened primates: black colobus [Colobus satanas], Preussi's guenon [Allochrocebus preussi], and russet-eared guenon [Cercopithecus erythrotis]), birds, and reptiles were hunted. The blue duiker (Philantomba monticola), giant pouched rat (Cricetomys emini), and brush-tailed porcupine (Atherurus africanus) contributed almost all the animal biomass hunted, consumed, or sold in both villages. Monkeys and Ogilbyi's duikers (Cephalophus ogilbyi) were hunted only by commercial hunters. Commercial hunters generated a mean of US$2000/year from bushmeat sales. Households with commercial hunters were on average wealthier, generated more income, spent more money on nonessential goods, and bought more products they did not grow. By contrast, households with subsistence hunters spent less on market items, spent more on essential products, and grew more of their own food. Despite these differences, average consumption of vegetable protein and domestic meat and bushmeat protein did not differ between villages. Our results highlight the importance of understanding the socioeconomic and nutritional context of commercial and subsistence bushmeat hunting to correctly interpret ways of reducing their effects on threatened species and to enable the sustainable offtake of more productive taxa.
在西非和中非,野生动物是食物和收入的来源。我们调查了在赤道几内亚比奥科岛的两个农村社区中,狩猎丛林肉与家庭财富和蛋白质消费之间的关系。一个村庄专门从事商业狩猎,另一个村庄主要为了食物而诱捕猎物。我们测试了商业猎人家庭是否由于其从丛林肉贸易中获得的更高收入和对野生动物蛋白的更大获取,在营养上优于以狩猎为生的家庭。我们在两个村庄进行了丛林肉采猎调查(猎人的捕获和到达每个村庄的兽尸)。哺乳动物(包括受威胁的灵长类动物:黑疣猴[Colobus satanas]、普雷西氏长尾猴[Allochrocebus preussi]和红耳长尾猴[Cercopithecus erythrotis])、鸟类和爬行动物都被猎捕。蓝麂(Philantomba monticola)、巨型囊鼠(Cricetomys emini)和刷尾豪猪(Atherurus africanus)几乎贡献了两个村庄中所有被猎捕、食用或出售的动物生物量。猴子和奥吉尔比氏麂(Cephalophus ogilbyi)仅被商业猎人猎捕。商业猎人每年从丛林肉销售中赚取 2000 美元。有商业猎人的家庭平均更富有,收入更高,在非必需品上花费更多,购买更多他们不种植的产品。相比之下,以狩猎为生的家庭在市场商品上的支出较少,在必需品上的支出更多,并且种植了更多自己的食物。尽管存在这些差异,但两个村庄的蔬菜蛋白、国内肉类和丛林肉蛋白的平均消耗量没有差异。我们的研究结果强调了了解商业和以狩猎为生的丛林肉狩猎的社会经济和营养背景的重要性,以便正确解释减少其对受威胁物种影响的方法,并使更具生产力的类群可持续采猎。
