Abstract

Abstract. The objective of the present study was to analyze the budgetary trends and the effectiveness of fisheries subsidies in Aceh Besar district. The literature and survey methods were utilized in this study. The secondary data of Aceh Besar’s budget documents in the period of 2010-2012 and key person interviews with fishermen leaders were conducted to analysis the subsidy trend and fishermen perception. The data was collected in May through July 2012. The results showed the budget allocation to the fisheries sector were increased from year to year, in 2010 the total budget for the fisheries sector was Rp1, 9 billions (equivalent to 0.34% of total buget or 1.40% of the development budget allocation/indirect consumption), in it was increased to Rp2, 9 billion in 2011 (or 0.42% of total budget or 1.47% of the development budget allocation), then increased sharply in 2012 to Rp9, 2 billion (an increase of over 630%) from the previous year, equivalent to 1.11% of the total budget. In 2010, the proportion of subsidies were given mostly for aquaculture sub-sector, which reached 84% of the total budget that was managed by the Department of Marine and Fisheries of Aceh Besar, whereas in 2011 the proportion of subsidies occurred balance between aquaculture and capture fishery sub sectors. However, in 2012 most of the budget DKP Aceh Besar (63%) was allocated to the capture fishery sub-sector. The results of the study showed that fisheries subsidies by the Government of Aceh Besar district especially in the last two years have not yet met the criteria of sustainable fisheries subsidies.

Abstract

Nile tilapia is a freshwater fish that is widely cultivated in Indonesia. During its development, tilapia aquaculture has constraints such as low growth rates. Therefore, it is necessary to add a feed additive to the feed in the form of charcoal. Charcoal is an adsorbent that has high absorption so that the addition of charcoal in the feed can increase the absorption of nutrients of tilapia. A 45-days trial was conducted to determine the percentage of addition of triggerfish bone charcoal (Abalistes stellaris) as a feed supplement that affect the growth performance and intestines of tilapia. The research design was a non-factorial Completely Randomized Design (CRD) with 4 treatments and 2 replications as treatments including: treatment A (control), B (addition of 1%charcoal), C (addition of 2% charcoal) and D (addition of 3% charcoal). A total of 240 tilapia fingerlings (5-7 cm) were used and placed in 8 aquariums then filled with 72 liters of water. Providing adlibitum (unlimited) feed with a frequency of 2 times a day. The ANOVA test showed that the addition of triggerfish bone charcoal (A. stellaris) in the feed was not significantly different (P 0.05) in weight growth, absolute length and daily length growth but it was significantly different (P 0.05) in feed conversion ratio and the efficiency of feed utilization. Based on result, it was concluded that the addition of 3% charcoal was the best treatment which gave the lengthiest of villi which was increasing the length of the intestinal villi to 71.11 µm from the initial length of 162.22 µm. easel at 233.33 μm, showed the highest feed conversion ratio value and feed efficiency (1.12 %, 89.6%).Keywords:CharcoalFish boneIntestinal histologyStarry triggerfish

Abstract

Abstract. Pomacentridae has a wide distribution in Indonesia waters. Research on species richness of Pomacentridae has been carried out in some areas in Indonesia. However, there are no data about the relationships of Pomacentridae on the southern coast of West Java. This research aims to know the evolutionary kinship of Pomacentridae ornamental fish in Ujung Genteng and Taman Manalusu Beach, West Java. This research used a survey method with a judgment sampling technique. The parameters measured were the consistency index (CI) and character evolution of the resulting phylogenetic tree. Cladogram reconstructed based on maximum parsimony algorithm with 1000 bootstrap replicates in PAUP software. The result showed that the tree had a CI value of 0.6000 which indicated low homoplasy. Pomacentridae formed a monophyletic group when they compared with Chaetodon collare as outgroup. The Pomacentridae clade divided into two subclades. The first subclade consisted of Abudefduf indicus as a basal species, then Neoglypydodon bonang and Plectroglyphidodon lacrymatus have a closed kinship and diverged after Dascyllus trimaculatus, and then Abudefduf notatus and Abudefduf sexfaciatus have a close kinship and diverged after Abudefduf vaigiensis. The second subclade referred to as a basal group, and within this subclade, Chrysiptera brownriggii has a closely related to Chrysiptera unimaculata and diverged after Chromis opercularis.Keywords: Cladistics, damselfish, meristic, morphometric, Pomacentridae

Abstract

The Java Sea with a surface area about 467.000 km2, is located in the South East Sunda Shelf with the average of depth is 40 meters, affected by several phenomena, whether physical or meteorological. This research aims to analyze the characteristics of water masses in the Java Sea and its relationship with the periodicity of the monsoon and Indonesian Throughflow Water (ITF) phenomenon. Then analyze the exchange of water masses in the Java Sea. The data used are temperature and salinity to identify the characteristics of the water masses. Ocean currents data to identify ITF patterns and winds data to identify the monsoon patterns. The data used in 2015 from the Infrastructure Development of Space Oceanography (INDESO) sites with a resolution of 1/12°. The method used is a descriptive analysis of spatially and temporally. The results show that averaging seasonal found that southeast monsoon period salinity is higher (31-34 psu) than northwest monsoon period (29.5-33 psu), and southeast monsoon period temperature is lower (27-30.5°C) than northwest monsoon period (28.5-30.5°C). ITF phenomenon occurs in May through September and reaches its peak in June, July, and August. ITF strengthened in southeast monsoon and weakened in the northwest monsoon. ITF and monsoon have similar impacts on salinity and temperature in the Java Sea. The water masses in the Java Sea comes from the South China Sea and Makassar Strait. In the northwest monsoon, Java Sea filled by water masses of the South China Sea, while in the southeast monsoon phenomenon which coincides with ITF phenomenon, Java Sea water masses is filled by water masses from Makassar Strait. In the transition monsoon I and II, the Java Sea filled by the South China Sea and the Makassar Strait water masses. Laut Jawa dengan luas permukaan sekitar 467.000 km2, terletak dibagian tenggara paparan Sunda dengan kedalaman rata-rata adalah 40 meter dipengaruhi oleh beberapa fenomena, baik fisikal maupun meteorologikal.

Abstract

Soft corals of the genus Clavularia (Blainville 1830) have complex and difficult to distinguish morphological characteristics, making them rather difficult to identify. A paucity of information exists for Indonesian coral reefs, a complex biogeographic region at the confluence of the Pacific and Indian Ocean that covers an extensive geographic area and several marine ecoregions, is subject to several ocean current systems, and includes a high diversity of habitats. Specimens of Clavularia inflata were collected from eleven study sites across the Indonesian archipelago, morphologically described based on their sclerite characteristics, and compared among sites. Sclerite observations were divided into four parts for each colony, namely pinnules, crowns, calyces, and stolons. The sclerites found in C. inflata comprised various forms such as rods, fingers, sticks, and brackets. Morphometric measurements of C. inflata showed specimens from Kepulauan Seribu had the largest pinnule, calyx, and stolon sclerites compared to other locations. The maximum mean size of crown sclerites was observed for specimens from Maluku Tenggara Barat. Similarities in the shape of sclerites resulted in specimens from Kangean, Morotai, Tanjung Lesung, Bontang, Lombok and Natuna forming a cluster, while those from Maluku Tenggara Barat and Arborek were dissimilar to other sites. Smaller sclerite sizes in specimens from Arborek are likely related to strong currents at that site. In conclusion, there were variations in the size of sclerites across the eleven study sites, with several sites forming a cluster of similar sclerite dimensions. Further studies using molecular markers are suggested to further explore the possibility of cryptic species.

Abstract

Global biodiversity, especially fish, has experienced a decline, this occurs as a result of over-exploitation, the presence of introduced fish species and climate change. This condition makes researchers look for solutions to overcome these problems by using cryopreservation techniques. The main purpose of cryopreservation is to store, maintain, and ensure the survival of genetic material, so that using cryopreservation techniques can maintain the viability and function of gamete cells both immunologically, biologically and physiologically. The success of the cryopreservation technique has made this technique widely developed in various species of living organism including fish. This article summarizes and reviews the history of the development of cryopreservation of animal species with specific focus on fish.Keywords:CryopreservationHistoryDepikEndemic species
