Habitat Quality Mud Crab (Scylla Serrata) in Mangrove Ecosystem of Bintan Bay, Bintan Distric, Riau Islands
Mud crab (Scylla serrata) is one of small scale fisheries commodity that have high economic value and typically associated with good mangrove ecosystem. A habitat degradation will cause a serious impact on the existence of mud crab population. The puropse of this study was to assess the ecological quality of mud crab habitat condition on Bintan Bay's mangrove ecosystem. Ecological data collection was conducted by using plots line transect for mangrove and the mud carb data collection by using fishermen catch (fisher based survey). The results showed the value of habitat quality index (HQI) of mud crab (Scylla serrata) ranged from 52-82 which mean in the āmoderateā category (index value 43-66) and "good" (index value 67-90). It showed that Bintan Bay's mangrove ecosystems was good enough to support the viability of mud crab. Habitat quality had a linier impact on body weight gain (R2 = 99.78%) and carapace width (R2= 99.21%). This showed that higher the index value of habitat quality, the size of the body weight and carapace width will increases
Dinamika Populasi Sumber Daya Ikan Layur (Lepturacanthus Savala) Di Perairan Selat Sunda (Population Dinamycs of Savalai Hairtail Fish (Lepturacanthus Savala) in Sunda Strait Waters)
Savalai hairtailis one of demersal fish that landed in PPP Labuan Banten with a fishing ground from the Sunda Strait waters. Savalaihairtail fish were caught by many gears (multigear) such as trawl, purse seine, small bottom trawl, and gillnet. This research aimed at reviewing population dynamic of savalai hairtail in Sunda Strait waters. The results showed the value of the growth coefficient (k) for female and male were 0,30/month and 0,23/month respectively, with asimptotic length (Lā) 710,41 mm for females and 856,52 mm for males. First length capture for females and males were 460,46 mm and 454,66 mm respectively. First length of maturity for female and male fish were 567,24 mm and 599,73 mm respectively. Natural mortality (M) for the female and male fish were 0,27/year and 0,22/year respectively. Total mortality (Z) for the female and male fish were 1,25/year and 1,60/year respectively. Based on the relationship between the values of M and Z, then the arrest of mortality (F) known for female and male fish were 0,97/years and 1,38/year respectively. The rate of exploitation for female and male fish were72% and 83% respectively. Based on the current rate exploitation, savalaihairtail fish exploitation has exceeded optimum exploited level (50%), so it indicated the savalaihairtail was overfishing. The value of Lc was smaller than Lm indicated savalaihairtail experienced growth overfishing

Laju Eksploitasi Sumber Daya Ikan Yang Tertangkap Pukat Cincin Di Selat Sunda (Exploitation Rate of Fisheries Resources Which Caught by Purse Seine in Sunda Strait)
Sunda Strait is waters which have great fishery potential in Indonesia. Catches of the Sunda Strait were landed in Pandeglang Regency, one of which is in the Coastal Fishing Port (PPP) Labuan. Purse seine is fishing gear with the highest production in Sunda Strait. Species targets of purse seine are Fringescale sardinella, Mackerel, Short mackerel, Indian mackerel, Kawakawa, and Indian scad. The high price of the fish lead purse seine operation continuously. Increasing purse seine operation can lead to the scarcity fishery resources. Therefore, a study about fish exploitation rate is needed to know the utilization status. The purpose of this study was to evaluate the exploitation rate of multispesies fisheries which caught by purse seine in Sunda Strait based on catch data landed data in PPP Labuan. This study used the ELEFAN I methods and Pauly formula. The result showed that the exploitation rate of fish resources for female and male fringescale sardinella are 0,79 and 0,70; Island mackerel are 0,78 and 0,60; short mackerel are 0,85 and 0,88; Indian mackerel are 0,80 and 0,83; kawakawa are 0,95 and 0,90; Indian scad are 0,75 and 0,62. Nowadays, all fish which caught by purse seine in the Sunda Strait has been indicated to over-exploitation
Analisis Sumberdaya Ikan Tembang (Sardinella Fimbriata) Di Perairan Selat Sunda Yang Didaratkan Di Ppp Labuan, Banten (Analysis of Fringescale Sardinella (Sardinella Fimbriata) Resources in Sunda Strait That Landed on Ppp Labuan, Banten)
Fringescale sardinella (Sardinella fimbriata) is one of the economically important fish resources found in Sunda Strait waters. High economic value with the increasing demand of fish makes it as one of the main targets of capture. Intensive utilization on fringescale sardinella resulted in overfishing. The aim of this research is to identify production pattern, fishing ground, fishing season pattern and appropriate alternative management. This research carried out on April to June 2014. The results show that fringescale sardinella has a fluctuated production pattern. Fishing season for fringescale sardinella is on May-October, while the fringescale sardinella bad season (low catches) is on March. Fishing ground for fringescale sardinella in Sunda Strait waters are Labuan Bay, Tanjung Lesung, Sumur, Panaitan Strait, Rakata Island, Ujung Kulon, Sebesi Island, Tanjung Alang-alang, and Peucang Island. Management for fringescale sardinella can be accomplished by increase the mesh size, management fishing season (open-close system) and fishing areas

Indian mackerel is one of the small pelagic fish that has an important economic value and the dominant fish catches landed in PPP Labuan. The catch of Indian mackerel decreaseyear to year. Therefore Indian mackerel resources, alleged have over-exploited. The aim of this research was to identify a production pattern, fishing ground, fishing season pattern and identify a more appropriate alternative recommendation for the management of Indianmackerel. The results showedthat the production of Indian mackerel had a fluctuated seasonal pattern. The peak fishing season was in April to August while low season (low catches) in December and January. Distribution of Indian mackerel fishing grounds wasin the waters around the Sunda Strait such as RakataIsland, Rakata Kecil Island, Anak RakataIsland, Panaitan Island, Papole Island, Sebesi Island, Sebuku Island, Jongor and Tanjung Lesung. Utilization status of Indian mackerel has already overfished in biology and economics. Some recommendation for managing Indian mackerel resources that were landed in PPP Labuan such as, reduce the fishing effort, increase the mesh size, and improvementmanagement infishing season and fishing ground
Variability of Carapace Width Size and Abundance of Blue Swimming Crabs (Portunus Pelagicus Linnaeus) in Pati Waters
Fishing effort enhancement would put pressure on blue swimming crab resources and its ecosystem. The objective of this study was to determine the spatial distribution based on the size of the carapace width (CW), abundance, temperature, salinity, depth, and fishing intensity in Pati waters which was divided into two zones (zones 1=nearshore, zone 2=offshore). The result showed that the average of carapace width in zone 1 to zone 2 was significantly different (p <0.05), as well as between males and females. Average number of individual (abundance) was significantly different according to fishing areas and sex (p <0.05). The average of water temperature in zone 1 was higher than in zone 2, salinity in zone 1 was smaller than in zone 2, and the water depth in zone 1 was shallower than in zone 2. The higher the crab catch intensity leaded to the smaller the abundance and size of carapace width. Alternative management strategies were proposed such as to divert fishing grounds from coastal waters to offshore during low productivity season, to uphold rules on minimum legal size for catching (Lm = 107 mm), to release of berried females catch, and to reduce accretion rate of gear and fishing fleet mainly in the coastal zone waters
