This week's In The News addresses overfishing, an international problem with new and urgent consequences. The nine sites discussed provide information and opinions on overfishing. According to a recent study published in Science (Feb. 6, 1998; Vol. 279), the commercial fishing industry is fishing harder at the lower end of the food web as larger and more commercially valuable species disappear. "Fishing Down," or the catching of second-level creatures normally preyed upon by larger fish, is the fishing industry's response to the depletion of prized species such as tuna, cod, and swordfish. The results of fishing "lower," scientists warn, is impoverished, less-valuable ecosystems. A further, alarming prediction is that this downward trend could lead to a wholesale collapse of marine ecosystems. Author Daniel Pauly and colleagues argue that there is an urgent need for marine protected areas, where fishing is prohibited.
