This study aims to describe the construction and operation of tagahu techniques in nike fishing in Gorontalo City. This research was conducted on January 5 to March 15, 2019 in Pohe Village and Leato Village in Gorontalo City, Gorontalo Province. The method used in this study is a descriptive method. The results of the study found that Tagahu is a long-shaped 4-piece jar with a pocket in the middle. Parts of the tagahu section are: 1) Main net, 2) Upper and lower Ris rope, 3) Buoy, 4) Ballast, 5) Buoy rope and Ballast Rope, 6) Capture rope, and 7) Buoy rope and Ballast Rope. The principle of Tagahu operation is generally similar to the operation of payang which is to wrap a net wing on a group of fish, then the net is pulled towards the boat. Tagahu catching can be done both at night and during the day. Tagahu's operation consists of: 1) searching of fish hordes, 2) dropping nets, 3) withdrawal and removal of nets, and 4) retrieval of catches. Keywords: Tagahu, Nets, Nike Fish

One of the mangrove forest area in Numfor Island is the Syoribo Coastal Coast currently the destruction of mangrove ecosystems is increasingly widespread due to the opening of land to be used as residential and development areas so that there is a reduction in the area of mangrove forests. The research was conducted in April 2018 at the Syoribo Village Coastal Coast of East Numfor District of Biak Numfor District of Papua Province. This study aims to analyze the types and distribution of mangroves, Analyze the composition of species and structure of mangrove vegetation (density, frequency, and dominance), Analyze the mangrove habitat is environmental condition affecting mangrove growth, Analyze texture of substrate which is overgrown by mangrove, Analyze the linkage between mangrove density and substrate texture found. The method used in this study is by combination between path method and line method then substrate analysis was conducted in laboratory. The results showed that in the four observation transects in 7 mangroves species were Sonneratia alba, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, Bruguiera cylindrica, Avicennia alba, and Xylocarpus granatum. The highest value index for tree, sapling and seedlings is the highest Bruguiera gymnorrhiza (197,82%), (160,71%), and (166,36%). Environmental conditions that affect mangrove growth are average temperature (27,6 0C – 29,4 0C), Salinity (6 ‰ – 24,3 ‰), Density (0,004 – 0,014), pH (7,12 – 7,57). The texture of the substrate overgrown by mangroves on the Syoribo, East Numfor have substrate criteria are dust silty clay loam, Silt Loam and sandy loam. Modeling the relationship between the density of tree level, spling, and seedling mangroves with substrate using multiple regression shows a close relationship between the two variables.

Gastropods is an important organism that commonly found inhabiting the rocky intertidal area. Distribution pattern of this species is influenced by various factors such as population history, microhabitat, predation and a complex interactions between oceanographic dynamics and ecological features. This study aims to compare the temporal distribution pattern of gastropods at two different rocky intertidal area. This research was conducted at the rocky intertidal area of Amban and Nuni, North Manokwari District, West Papua. Data collection was performed during the daylight and night in April and June 2012 using systematic sampling method. The results showed that both physical and chemical factors are suite for supporting gastropods life. Furthermore, these factors seem to have an impact on gastropod zoning patterns observed in the study area. The similarity index values indicate that the similarity of gastropod species between the two locations is low, which means that the species of gastropods found in each location is quite different. The community structure of gastropod at the study area is stable. In addition, we found that the gastropods diversity were higher during the night than the daylight because gastropods are classified as a nocturnal animals.

The phenomenon of marine cryptic species is frequently found in altered ecosystem such as dead corals habitat. Dead corals as habitat can be used by marine fauna like crustacean from family of porcellanidae. This study was aimed to identify and clarify the species of porcelain crab from Tundai sland, Banten province by applying the morphological analysis and DNA barcoding technique. The result of morphological analysis showed that decapod samples were crabs of the genus Pisidia, family of Porcellanidae with specific morphological characteristics were the ratio of carapace size is longer than tbroad, have long antennae which can be moved, serrated anterior rostrum, chelae rather flattish and unequal size of arms. While based on molecular barcode analysis by using COI, samples were identified as Anomura sp. with 94% of similarities. The difference of the result was suspected due to the lack of suitable genetic data on genbank.

Minaluli Village has the availability of mangrove ecosystem resources in coastal areas. The availability of evenly distributed mangrove ecosystems can have a direct impact on the community. Determination of mangrove status conducted previously using conventional methods such as transect quandrat and spot check. Hemispherical photography method is one of the new methods used and developed in Indonesia. The study was conducted in July 2018 in Minaluli Village, North Mangoli District, Sula Islands Regency. North Maluku Province. The research objective is to obtain information on the condition of the mangrove ecosystem using the Hemispherical photography method. The results of the study obtained measurements of environmental parameters showed that environmental ecological conditions support the existence of mangroves. Morphological identification was obtained as many as 8 species from 3 families. Station I found 82% mangrove cover presentation value, for station II found 77% cover presentation, at station III found a presentation found 78% while at station IV found a presentation of mangrove cover 72%. The total presentation of mangrove cover obtained in the solid category, based on the standard criteria for mangrove damage. The density of the mangrove ecosystem obtained shows high density at each station. Based on the standard criteria for damage, the density of mangroves in this location is in the medium to very dense category with a value range between 1,067-2,022 trees / ha. Important value index (INP) analysis of each type of mangrove found a range of values between 31.73-95.55 The highest value index of the highest species was found in the Rhizophora stylosa type with a value of 95.55% then Rhizophora apiculata with a value of 95.08%, Rhizophora mucronata namely 81.05%, Xylocarpus granatum is 45.68, Ceriops stagal with value of 40.83%, Sonneratia alba with a value of 36.27 and Bruguiera gymnorhiza 31.73%.

The Gondang Reservoir is the largest in the Lamongan District, another function this reservoir for irrigation is also for use fishery and tourism. Fisheries production in this reservoir are not optimal and number of tourist getting lower, that result public welfare has not yet create. Therefore we required the data about carrying capacity natural fisheries Gondang reservoir for development of optimal and sustainable water management. This research used the descriptive method with purposive sampling at May until August 2018. Analysis carrying capacity use approach result the water primer productivity with Beveridge Index. Average result of water primer productivity in Gondang Reservoir was 86,26 gC/m2/year. Carrying capacity natural fisheries in Gondang reservoir is 4,4 tons of fish/year or 12,17 kg of fish/year.
