Introduction: Fishing is a major part of many Caribbean economies. The yellowtail snapper and Nassau grouper are important food fishes. However, a lack of adequate regulation has led to overfishing in many areas and consequent damage to reefs. The goals of this activity are to observe the effects of overfishing and determine how much fishing the reef can withstand. Question: What are the effects of fishing on the reef ecosystem? 1.
