Geography and human ecology of reef fisheries

摘要: Throughout the tropics, reef fish stocks are exploited mainly by individual households and communities to fulfil subsistence requirements often yield a small saleable surplus. Small-scale commercial fisheries also common. As consequence, social economic organization of varies considerably, precluding useful generalization here. On other hand, harvesting in exhibits similar adaptations physical characteristics site cyclical change within it. Gear types relatively simple, with notable exception parts Pacific Basin South East Asia. A brief discussion these similarities forms core this chapter. Another shared feature is that almost everywhere under intensifying pressure from external forces, especially urban growth. These pressures others lead more intensive fishing many contribute weakening local systems hitherto controlled The geography human ecology fisheries, despite some unifying similarities, complex locally detailed subject, which can be only cursorily summarized Because fast changing, cases becoming extinct, make systematic comprehensive geographical ecological studies them an increasingly urgent task.
