It’s a part of Mainland fishing tradition to selectively take larger individual fishes from a population, leaving the smaller ones to grow. However, the larger individuals species often have a different role in the coral reef ecosystem than do the smaller ones, and this role can be important for the reef community. Dr. Charles Birkeland of the University of Hawaii-Manoa will discuss how leaving the big fish can help maintain the coral reef ecosytem and the stability of fish populations. His lecture, “Leaving the Big Fish: The Importance to Coral Reefs,” will  start at 6 p.m. May 8 at the Atherton Halau. Free and open to the public. Call 847-3511 or visit www.bishopmuseum.org.
