Many creatures living on the bottoms of the deep ocean and deep lakes depend on marine snow,animal and plant plankton that die and drift downward from the lighted regions above.Because this food is limited deep-dwelling fish species tend to reproduce slowly.This makes them especially vulnerable to depletion from overfishing.
很多動物生活在身海底部和湖底仰賴著維生物維生,死掉的和漂流的動物和浮游生物會從輕地帶上面下降,因為那些食物是限制深海魚種類,牠們往往繁殖的很緩慢,而過度捕撈會使牠們特別的脆弱
