Nudibranch in Reefball In May 2005, there were 300 artificial reefs, which known as reefball, deployed in lagoon of Pulau Layang Layang Malaysia. Reefball was made from the mixture of granite stone and concrete, with dimension of 1.31m height and 1.68m width. Reef Ball?s objective is staying solvent and enhancing the overall marine environment. Monitoring of reefball was conducted on 12th-17th June 2007. The objective of this survey is to observed the present of nudibranch in reefball, Pulau Layang Layang Malaysia. Currently, there are 300 units of reefball inside the lagoon of Pulau Layang Layang, 200 units located at latitude of 7° 22? 38.3?N and longitude 113° 49? 3.43?E. The other 100 units was located at latitude 7° 22? 38.4?N and longitude 113° 49? 4.30?E. For preservation and fixing method, the specimens should be relaxed to retain, more or less, their original body shape. The simplest...
Stack of Reefballs in Lagoon?s Pulau Layang Layang You might call the Reef Ball an underwater condo for fish, especially grouper and snapper. After the Reef Ball is in the water awhile, marine organisms begin to grow, small fish move in and then larger fish. Bill Lindberg, associate professor at the University of Florida?s Department of Fisheries, says an artificial reef can boost fish population by about 8 percent. If a reef site is over-fished, it can result in a decrease fish population. Reef Balls have holes that not only go into the module but between the walls. The large open area in the center is designed to provide fish shelter. The holes are designed to create vortexes which feed the invertebrates and corals. Many other artificial reefs assume that surface area or profile alone...
