Detailed reef study shows why it’s important to maintain healthy fish communities

FRISCO — Although fish are often thought of as predators that graze on microorganisms, plants and smaller animals, it turns out they play another crucial role in the marine ecosystem. Through excretion, they recycle the nutrients they take in, providing the fertilizer sea grass and algae need to grow.
The administration’s oceans policy is aimed at protecting, maintaining and restoring the health of economically critical marine ecosystems, thereby providing a sustainable flow of ocean resources for coastal communities, but the Republicans in Congress are more intent on continuing the short-term plunder of fisheries and other natural resources, with no thought about future generations.

According to a report released today, Mediterranean fishermen have been violating quotas at will and have engaged in numerous illegal fishing practices, including misreporting catch size, hiring banned spotter planes, catching undersized fish, and trading fishing quotas.
Spawning stock of the eastern Atlantic bluefin has plummeted nearly 75 percent since 1974, The fish is the favored source of red tuna sushi and sashimi. Japan makes up three-quarters of the world market, but the fish is also served in restaurants from Paris to New York. Each year, thousands of tons of fish have been illegally caught and traded. At its peak — between 1998 and 2007 — this black market included more than one out of every three bluefin caught, conservatively valued at $400 million per year.

Transplanting elkhorn corals shows promise for restoring reefs on a local level, but large-scale, long-term threats are undiminished

SUMMIT COUNTY — Coastal and island residents may be able to restore some coral reefs damaged by global warming and fishing by transplanting new pieces of coral on to damaged reefs.
The research was done Dr Graham Forrester, from the University of Rhode Island, who led a team of scientists, students and local residents to try and restore a dead at White Bay in the British Virgin Islands. Their findings revealed that transplanting pieces of coral onto damaged reefs improved coral growth and survival rates.
Through careful long-term monitoring, the team was able to measure the results of its success. They found that transplanted pieces of elkhorn coral reattached themselves after three months and grew into large adult corals after four years. Continue reading “Good news for coral reefs?”→
