Abstract. Jefri E, Zamani EP, Subhan B, Madduppa HH. 2015. Molecular phylogeny inferred from mitochondrial DNA of the grouper Epinephelus spp. in Indonesia collected from local fish market. . Groupers are widely distributed in the tropical and subtropical coastal waters, and are globally one of the most commercially important groups of marine fish, commanding high market price and are being heavily targeted in fisheries. Over fishing in Indonesia becomes a pivotal factor, which is seriously threatening the grouper biodiversity, as separate catch statistics are not reported for most species, and landings are often summarized as 'serranids' or 'groupers'. This lack of species-specific catch data is due to the difficulty of identifying many of the species. The focus of this study was the tracking of molecular phylogeny of Epinephelus spp. of the family Serranidae. DNA amplification using mitochondrial cytochrome oxidase I resulted in 526-base pairs long sequences all samples. A total of seven species were characterized that are (Epinephelus areolatus, E. merra, E. fasciatus, E. longispinis, E. coioides, E. ongus and E. coeruleopunctatus). All of which were found to belong to 7 different clades in the constructed phylogenetic tree. E. ongus is genetically closest to E. coeruleopunctatus with genetic distance 0.091 (9%), whereas the farthest genetic distance was successfully identified between E. ongus and E. merra with genetic distance 0.178 (18%). Migration activity on spawning and movement of larvae that are affected by Indonesian Through flow suspected as the cause of the closeness between species grouper Epinephelus spp. in the phylogeny tree from several Indonesian seas, although information about the location and time of Epinephelus spp. spawning activity sometimes difficult to obtain certainty. Fish identification using molecular phylogenetic approach has been successfully applied in this study. It seems need further application on this method to avoid misidentification and due to high variety of species landing at local fish market. Nevertheless, this study would be an important data in the genetic management for the sustainable conservation and trade of grouper (Epinephelus spp.) in Indonesia.

Protection and sustainable data collection are very important in order to protect the coral reef ecosystem. This research was conducted to monitor and determine the condition of coral reefs in the eastern part of Gili Gede Island, which is administratively located in Sekotong Sub-District, West Lombok Regency, NTB. The method used is Line Intercept Transect (LIT). Furthermore, the starting point of the transect stretch is recorded using GPS coordinates and the depth gauge is used to estimate the depth of the water. The results showed that the status of coral reefs tended to be badly damaged with the mean value of all stations (21.92%). Fishery activities and pressure from the land are thought to be several factors that tend to affect the poor coastal ecosystem

Seagrass is a coastal ecosystem that has important role as a feeding ground, a spawning ground and a nursery ground for various marine biota. This study aims to examine the biodiversity of seagrass at Gili Air, North Lombok Regency, West Nusa Tenggara. This study was conducted to observe the cover percentage of seagrass, it's composition, the number of seagrass stands, canopy's height, frequency of seagrass presence, and index of importance of seagrass. Seagrass data was collected using a 50cm x 50cm quadrant transect, with a total area of 100 m2, referring to the monitoring standards set by SeagrassNet. Water quality analysis was carried out at the Bioecology Laboratory of the Aquaculture Study Program, University of Mataram, and at the Laboratory of the Marine Aquaculture Center (BPBL) of Sekotong, West Lombok. The results showed that the seagrass communities in Gili Air waters were composed of 5 (five) species: Halophila ovalis, Thalassia hemperichii, Cymodocea rotundata, Halodulea pinifolia, and Halodule uninervis, with the percentage of coverage ranging from 26.88-39.17%, and the average coverage by 31.53%. Thalassia hemperichii is the species that has the highest contribution to the seagrass community at Gili Air.

The Teluk Awang Fishery Port (PP) is located in Mertak Village, Central Lombok Regency, which has the potential to develop as a center of economic growth with a fishery business base. It has a good geographical location because it is protected from waves coming from the Indian Ocean. Currently the Central Government, West Nusa Tenggara Provincial Government and Central Lombok Regency Government are jointly developing Awang Bay as a fishery business center by building a fishing port that can accommodate fishing vessels operating in WPPNRI 573 and 713. This study will look at fish resources ( SDI) in PP Teluk Awang uses the Participatory Action Research (PAR) method which actively involves all relevant parties. The results of the research show that the SDI that was landed in PP Teluk Awang during 2018-2020 as much as 3,559,483 kg was still dominated by pelagic and demersal fish, such as Cakalang fish (62.67%), Layang (10.77%), Tongkol ( 8.29%), Lemadang (6.34%), Tuna (5.42%), Baby Tuna (3.88%), Marlin (1.48%) and other fish (1.15%). The recorded fleet of ships is 27 units with a size of 8-25 Gross Tonnage (GT). The results of this study are expected to be a recommendation related to policies in managing the potential of SDI landed in PP Teluk Awang with the concept of sustainable fisheries.
