The confluence of these currents produces a rich feeding ground for countless fish varieties. Another favorable natural feature is that the area sits on an extensive section of the continental shelf so that no matter what the nature of the coast, be it eroded, coral reef, rugged, boulder-strewn or man-made breakwater, all provide excellent fishing locales.
不分四季，岩質海岸的礁層區內都聚集有種類不同的魚群或覓食、或產卵；落差大的深海處則有底棲的大魚迴游。釣者在這類水深流急或海蝕礁層地區，站在礁岩上下竿，就稱作「磯釣」。
