Abstract

ABSTRAKNelayan di Desa Toniku Kabupaten Halmahera Barat, awalnya menggunakan bagan perahu untuk menangkap ikan teri Stolephorus sp. sebagai umpan perikanan pole and line, akan tetapi pada saat ini banyak tertangkap selain teri yaitu juvenil dan larva ikan, ini permasalahan yang perlu dikaji komposisi tangkapan dari bagan perahu. Tujuan penelitian  adalah  menganalisis komposisi tangkapan, by-cacth, discard, dan aspek ekonomi. Penelitian  dilaksanakan di perairan desa Toniku Kabupaten Halmahera Barat, dari tanggal 1 sampai 9 Juni 2018. Metode penelitian adalah metode survei. Obyek penelitian yaitu ikan hasil tangkapan bagan perahu. Hasil penelitian menunjukkan bahwa tangkapan bagan perahu didominasi oleh ikan target tangkap, yaitu; ikan teri (Stolephorus sp) sebesar 86,295%, tangkapan sampingan  12,335% dan tangkapan yang dibuang 1,370%. Tangkapan sampingan didominasi ikan  peperek (Leiognatus sp) yaitu 5,575%. Nilai keuntungan Usaha bagan perahu sebesar Rp 93.047.200,00/tahun dengan B/C ratio 2,96. Berdasarkan perbandingan antara target tangkap dengan by-catch dan discard, bagan perahu di Desa Toniku Kabupaten Halmahera Barat dikategorikan alat tangkap ramah lingkungan dan secara finansial menguntungkan dan layak dikembangkan (berkelanjutan). Walaupun discard rate pada bagan perahu rendah namun usaha-usaha untuk meminimumkan tetap perlu dilakukan. Salah satu usaha yang bisa dilakukan adalah sortir, dan hasil tangkapan yang tidak memiliki nilai ekonomis dibuang ke laut dalam keadaan masih hidup. ABSTRACTFishermen in Toniku Village, West Halmahera Regency, initially used a boat lift net to catch anchovy Stolephorus sp. As bait for pole and line fisheries, but at this time many were caught besides anchovy, namely juvenile and fish larvae, these are problems that need to be studied from the boat lift net. The study objective was to analyze the composition of catchs, by-catch, discard, and economic aspects. The research was carried out in the waters of Toniku village, West Halmahera Regency, from June 1 to 9, 2018. The study method is the survey method. The object of the research is the fish catch by the boat lift net. The study results show the catch of the boat's lift net was dominated by main catch, namely; anchovy (Stolephorus sp) is 86.295%, by-catch 12.335% and discard 1.370%. The bay-catch  is dominated by peperek (Leiognatus sp) which is 5.575%. Value of the boat lift net business profit of Rp. 93,047,200.00/year with B/C ratio 2.96. Based on the comparison between catch targets and by-catch and discard, the boat lift net in Toniku Village, West Halmahera Regency is categorized as environmentally friendly and financially profitable and feasible (sustainable) fishing gear. Although the discard rate on the boat chart is low, efforts to minimize it still need to be done. One effort that can be done is sorting, and catches that have no economic value are dumped into the sea while still alive.

Abstract

Flying fish eggs are one of the fisheries commodities that have important economic value in the waters of Tual City. Based on the Decree of the Minister of Maritime Affairs and Fisheries Number 69 of 2016 concerning the Plan for the Management of Flying Fish Fishery, several priority issues that are the problem of flying fish are; (1) fish resources and habitat; (2) social and economic; (3) governance. The flying fish fisheries management plan is expected to support policies in the management of flying fish and flying fish eggs in the Fisheries Management Region of the Republic of Indonesia. The purpose of this study is to analyze the system problem situation and build a model for the development of flying fish egg fisheries. This research method uses system approach. The four-step system approach starts from needs analysis, problem formulation, system identification and system modeling. The results showed that the root problems in flying fish egg fisheries were many ships that did not have permit documents, the availability of data on potential fish resources, the use of fishing gear that were considered environmentally unfriendly, low human resources, high fuel prices and access to capital for fishermen. The model of developing flying fish eggs consists of submodel use of environmentally friendly fishing gear and submodel of the development of flying fish egg fishing business. The problem of flying fish egg fisheries in Tual PPN can be solved by the solution of the use of environmentally friendly fishing gear for flying fish resources and the development of the fly fish egg fishing business.

Abstract

The standard of measurement of abalone is very important because it can help to identify accurately abalone shellfish based on shell morphology. This research was aimed to examine the truss morphometric and morphologycal characters of Haliotis squamata intraspecies in the southern coastal Java and Bali. The research was conducted from December 2014 to August 2016. Abalone was collected based on the purposive sampling method, it was then identified. The shellfish of abalone was measured and analyzed by using principal component analysis (PCA), canonical discriminant analysis and cluster analysis. The results showed that PCA was able to separate Haliotis squamata populations from Java and Bali using combination of PCIII and PCIV based on the factor coefficient values. The key characters that separated Haliotis squamata from the population of Java and Bali were the combination of characters BF (0.535) for PCIII and characters CH (0.522) for PCIV. Canonical discriminant analysis showed that Bali was the highest sharing component value (100%) of intra population and also the lowest sharing component of inter population (0%). The highest percentage of similarity was 99.91% that indicated the population of Binuangeun and Pangandaran, while the lowest was 99.31% for the population of Banyuwangi and Bali. The morphological characteristics of Haliotis squamata species in several locations showed specific characters such as color patterns, textures and shapes.

Abstract

Manta ray (Mobula alfredi and Mobula birostris) is an endangered species that protected by international and national law. This species is vulnerable because of commercial fisheries and anthropogenic threats. These threats have impacted the species population worldwide. Raja Ampat is home for both species of the manta ray, and the area is protected with conservation status. Manta Sandy is located in Dampier Strait, is a popular dive site in Raja Ampat visited by thousands of tourist per year. It is vital to ensure the manta sightings in this area to maintain the tourist volume for local economic benefits. Utilization of photo ID and mark-recapture technique conducted to document the spots on the belly of manta ray that identify a unique pattern of each fish. This study conducted in low season from July to August 2018 for 15 days from 08.00-16.00 used two cameras of go pro hero 4 with extra battery power. The result documented time of manta sightings and species characteristic (size, sex, species, behavior, and color morphology). The camera trap recorded four manta rays where the two of them were new identified individuals.

Abstract

The aims of this study were to compare skipjack catch between FAD and free school fishing grounds and to describe the effect of the oceanographic factors on either skipjack tuna Fish Aggregating Device (FAD) or free school.  We used a field survey method for collecting the skipjack catch and the fishing positions for both near FAD and free school areas.  Remotely sensed satellite data of sea surface temperature (SST) and chlorophyll-a concentration (Chl-a) were also used to extract the oceanographic data corresponding with both the fishing locations. To find out the vital oceanographic factors, we examined the characteristics of the oceanographic variables and skipjack catch using t-test. Results indicated that the fishing operations of skipjack tuna at FAD tended to locate areas of relatively higher Chl-a than at free school locations. We also found that skipjack tuna catch was higher near the FAD than the other area, where the Chl-a was the most significant factor that affected the difference. This study suggests that the number of skipjack tuna FAD in the coastal waters of Bone Bay should be calculated accurately to ensure and support the tuna fishing management in that study area.

Abstract

This study aimed to identify the changes of oceanographic parameters and to analyze the effects of the parameter changes on the distribution and abundance of skipjack tuna captured by purse seine fishing gear operated in Coastal Waters of Makassar Strait. This study collected fishing and field oceanographic data from May to October 2017. A survey method was used to obtain primary data (skipjack catch per unit effort/CPUE) and secondary data including sea surface temperature (SST) and Chl-a level 3 with a monthly temporal and spatial resolution of 4 km from 2007-2017, interview, and study literature. The data were processed by using SeaDAS and ArcGIS software packages and were analyzed by anomalies, standard deviation, and Generalized Additive Models (GAMs) analyses. The results showed there were anomalies for both SST and Chl-a near study area reflecting the significant changes in the oceanographic conditions. The changes for both SST and Chl-a were 1.5ºC and -0.97 mg.m-3 respectively. This study suggests that the Chl-a parameter has more significant effects on skipjack tuna distribution and CPUE than SST. Understanding of the areas of the oceanographic changes strongly supports the available habitat for the fishing operation and conservation

Abstract

Jakarta Bay as one of an area with the densest population in Indonesia became one of the highest contamination level waters in the world includes pollution of debris. Reclamation activities in Jakarta Bay will change the water conditions, and will also affect the distribution of debris at sea. Therefore, this study conducted is to determine the movement of the marine macro debris before and on the condition of the existing reclamation island in the Bay of Jakarta. The method used is simulated by the hydrodynamic model and particle trajectory models using MIKE software. Data needed for the hydrodynamic model, namely wind, tides, bathymetry, and shoreline, while for the trajectory of the particles using a data type of debris, marine macro debris weight, and debris flux. The analysis was performed for hydrodynamic model simulation results and comparison of particle trajectory models. Hydrodynamics simulations indicate if a reclamation island formation does not change significantly in the offshore area, but a simple change in the surface current pattern of the reclamation area, it also causes a decrease in the flow velocity of ± 0.002 to 0.02 m/s at some point. Macro debris particle trajectory simulation shows if after reclamation, macro debris tends to accumulate in the eastern Jakarta Bay in the rainy season (January), as well as in the western and eastern regions during the dry season (July).

Abstract

Stable carbon isotopes have been commonly used as indicators for assessing environmental changes in aquatic ecosystems. They can be used to study the dynamics of organic matter as for understanding the overall functioning of the ecosystem, the connectivity of estuaries with terrestrial and marine coastal habitats. The objective of this study is determining the seasonal natural effects over isotopic (13C/12C) baselines in monitoring CO2 storage in dissolved inorganic materials in Spermonde waters on the west coast of South Sulawesi to some outermost island. The results show that the stable carbon isotopic of DIC (d13C-DIC) in the wet season varied between -5.36 ‰ and -7.74 ‰. These value are higher than on dry season (-4.34 ‰ to -6.82 ‰). Likewise, DIC concentration in the rainy season ranged between 9.5 mg C/L and 11.7 mg C/L, while in the dry season it varied from 8.5 mg C/L to 9.3 mg C/L. The d13C-DIC and DIC concentrations decreased towards offshore, up to some of the outer islands. Increasing in the d13C-DIC in Spermonde waters indicate that the DIC is most likely enriched by atmospheric CO2(g), which is outnumbered those of aquatic photosynthesis. This study shows that different levels and composition of d13C-DIC stretch along different rivers are attributable to the varying landscapes and quality of organic matters.

Abstract

Sabang coastal bay becomes the area of significance where the development centered in the semi-enclosed area. Sabang Bay is well-known as the center of marine economy (Aquaculture, Harbor, and marine tourism). Recently, there is a planning initiated by Ministry of Marine Affairs and Fisheries (MMAF) to install the floating fish cage aquaculture (KJA) in the offshore area of Sabang Bay which the planning becomes a controversy between local people, local government, and researchers as well. This study aims to evaluate and discuss the impacts that will be happened if KJA is applied. Field surveys on hydro-oceanography aspects were done measuring currents, tides, waves, winds, bathymetry, water quality, as well as tourism condition. Based on those hydro-oceanography conditions, Sabang Bay categorized into calm water area where the sea current is weak (ranging from 0-0.12 m/s), whilst the high values of pH, salinity, and temperature are identified within the bay during low tidal condition. If KJA is installed within the bay, automatically it will pollute the water due to the accumulation of remaining fish feeder wastes. Moreover, within the bay, there are several attractive marine tourisms such as diving sites, the conservation area of Sophie Rickmers shipwreck site, and hot bubble (fumaroles hydrothermal vent). The presence of KJA will possibly disrupt marine tourism activities so that the implementation of KJA needs to be considered the impacts before installation.
