Abstract

Rock fish is a specific fish which lived in around rock ridge area. The increasing of rock ridge area exploitation and the catch of ridge rok fish which didn’t pay attention to the environment, cause a wide-spread damage, especially in region where rock fish lived, the rock ridge area. In this area, rock fish has large amount and a large organism. With its large quantity fulfilling rock ridge area, there could be seen that rock fish was a supporter of relation in rock ridge ecosystem. White Sand beach was known as a beach which rich of fish and rock ridge. But as time goes by, the fish variant and the beauty of rock ridge was decreasing. It caused by continuous exploitation by people around which caused the higher damage of rock ridge area. Opening white sand as tourism object and lack of sea protection area could decrease the rock fish population. Based on the fact, there needed a population record about the amount and the kind of rock fish, especially in Watu Lawang and Pon-pon rock, white sand, Bungatan sub-district, Situbondo residence. The research aimed to find out about the various kind and amount of rock fish, to find out physical, chemical, and biological condition to the rock fish habitat and also find out factors damaging rock fish ecosystem in Watu Lawang and Pon-Pon rock water area White sand beach, Bungatan Sub-district, Situbondo Residence. The benefit of this research was: to increase knowledge in rock ridge monitoring using Reef Check method. It could be an information used as consideration for related policy to protect the species of rock fish, it also could be used as further research to use, develop, and keep the sea source in continuous and unity way. The research was done in November – December 2008, while primary data was taken in 15-16 November 2008 in Watu Lawang water area and Pon-Pon rock, White Sand beach, Bungatan sub-district Situbondo residence. In this research, the investigated object was kind and amount of rock fish, using Reef Check method. This method was done in 2 depth, 3 m and 10 m according to the lowest lessened data. From the research, the kind and amount of rock fish, that was Watu lawang in Site 1 (Watu Lawang) in 3 meters depth, there found Butterfly fish species, Haemulidae, Snapper and Parrotfish. In 10 meters depth, there found more rock fish. They were Butterflyfish, Haemulidae, Snapper, Barramundi cod, Grouper, Humphead wrasse and Parrotfish. In Site 2 (Pon-pon rock) at 10 meters depth, there found several species fishes, they were: Butterflyfish, Haemulidae, Snapper and Parrotfish. In 3 meters depth there found rock fishes: Butterflyfish, Haemulidae, Snapper and Parrotfish and Grouper. Water quality which was measured at location (Watu Lawang and Pon-Pon rock) showed temperature 26 - 280C, salinity 31 - 32‰, flow around 7 – 9,2 m/detik, DO in average 4,56 – 6,601mg/l and pH around 8 – 9. From the water quality measurement at location, it was still in normal rate for rock fish life. Ecosystem around Watu Lawang and Pon-Pon rock water area was not worth for rock fish life, since in the location could not found padang lamun ecosystem and mangrove ecosystem. In this location, rock ridge placed behind local villagers and there was not much shrimp pond which dominated the sea-shore, where the household waste was thrown to the sea and influenced the rock ridge life as the ecosystem of rock fish. Fishermen’s boat was also influenced the life of rock ridge, since the anchor brought down by the fishermen could damage the rock ridge which lived in the area. The researcher suggest to do illuminatio to the society around and tourists about the importance of rock ridge life for rock fish and there was needed a monitoring of rock fish population each year, to find out the development of rock fish ecosystem so that the population and amount was not decreasing.
