THE SURVIVAL OF TRANSPLANTED CORAL ON PYRAMID-SHAPED FISH SHELTER ON THE COASTAL WATERS OF KELAPA AND HARAPAN ISLANDS, KEPULAUAN SERIBU, JAKARTA
Authors: Johan Ofri 
Published: October 2016

Research was carried out in August 2008 at two sites within Marine Protected Areas (MPA) in Kelapa and Harapan Islands of Seribu Islands, Indonesia. The purpose of this research was to compare the mortality rate of coral transplanted on the upper and base of pyramid-shaped concrete fish shelters. Fish shelters were placed on the seabed of Kelapa Island which is characterized by sandy seabed and Harapan Island which is characterized by silt. Both sites are within Marine Protected Areas. The survey recorded mortality rate of transplanted coral and percentage of live coral coverage. The research also sampled fish populations within the MPA sites and pyramid areas so that the two sites can be compared for their fish biodiversity. The data were analyzed by using T-Test Student of SPSS 11.5 computer program to compare between two locations, and upper and base of transplanted position. After one year, the average mortality rate among transplanted coral species in Kelapa Island was 34%. However, the mortality rate of transplanted coral in Harapan Island was slightly higher than in Kelapa Island: 42%. The transplanted coral at the top of the fish shelter had higher survival rate (39%) compared to the base of the fish shelter (24%). Fish populations in Kelapa Island consisted of 1,119 individuals from 35 species. This was much higher than in Harapan Island where the research found only 655 individuals from 27 species. Fish populations found around the fish shelter area in Kelapa Island consisted of 125 individuals from 25 species. This was lower than the fish population in Harapan Island, where 206 individuals from 23 species were recorded.

Pinctada maxima is a filter feeder organism obtaining food particles by filtration from water suspension. Filtration and ingestion rate of a large number of benthic filter feeders in a variety of coastal environment have been known influenced by current velocity. The purposes of this study were to examine the effects of current velocity on filtration and ingestion rate of pearl oyster P. maxima and to determine the best current velocity. Randomized Block Design was used in this experiment with four current treatments of 8, 16, 24, and 32 cm s-1. The results of this experiment demonstrated that current velocity has a marked effect on filtration rate of P. maxima and that this species follows the general pattern of response observed for other bivalves. Different velocity affected filtration and ingestion rate in pearl oyster P. maxima. It was gradual decline in the suspension feeding with increasing velocity. Filtration rate of bivalves with siphons facing into the current, were directly inhibited by hydrodynamic effects on the functioning of the bivalves pump. At increasing current velocity, pressures applied to the inhalant and exhalant aperture facing into the flow would result in higher pressures than that of produced by the ciliary pump, resulting in reduced filtration rate. The highest filtration and ingestion rate in this experiment were obtained at velocity of 8 cm s-1 that achieved 3.409±0.485 l/h and 37.91±1.27 (x107) cells/h, respectively.

Abalone is a herbivore marine animal which feeds on seaweed. Abalone culture has a good prospect in terms of price, market share and simple culture technique. Thus, a study was conducted with the aim of finding out an effective and efficient abalone culture technique in terms of feed use and density. In this study, a 42 cm diameter plastic container with a 22 cm height was used. Three vertically arranged containers were used as the experimental group which were put into a net box and hung onto a raft so that the containers were placed in a 4 m depth below the sea surface. The juvenile of abalones being used came from a hatchery production that has been adapted to cages environment with Gracilaria sp. and Ulva sp. feed. The initial density of abalones was 450 for each container, with the initial weight of 2.6-3.2 g and the 2.5-2.7 cm shell lengths. The abalones were fed with Gracilaria sp. and Ulva sp. seaweeds with different Gracilaria sp./Ulva sp. proportions, i.e. 100/0% (A); 80/20% (B); and 60/40% (C) as the treatments. Each treatment consisted of two replications. After three months of rearing period, densities of abalones were reduced to be 190 for each experimental unit. Weight and shell length of abalones were measured every month by measuring 25 abalone samples from each experimental unit. The result of the experiment showed that the increase in the Ulva sp. proportion in the feed increased the growth of abalones and decreased the feed conversion. Feeding with Gracilaria sp./Ulva sp. proportion of 60%/40% allowed the best growth of abalones. The decrease of abalone density in the experimental unit after three months of rearing also produced an increase in their growth.
DETECTION OF Macrobrachium rosenbergii Nodavirus (MrNV) AND EXTRA SMALL VIRUS (XSV) DISEASES ON GIANT FRESHWATER PRAWN, Macrobrachium rosenbergii AT SAMAS, YOGYAKARTA
Authors: Koesharyani Isti , Gardenia Lila 
Published: October 2016

Mass mortality of giant freshwater prawn (Macrobrachium rosenbergii de Man) in grow-out farmers occurred in early February 2012 at Instalation Coastal of Aquaculture Samas, Bantul, D.I. Yogyakarta. The clinical sign of shrimp was whitish coloration on abdominal and tail muscle. The sympton was the same as in other cases of mortality caused by prawn Macrobrachium rosenbergii nodavirus (MrNV) and Extra Small Virus (XSV). Prawn samples were diagnosed by standard protocols Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) using specific primers and histopathology analysis. The result showed that all samples indicated positive 13/15 the MrNV and 5/15 positive XSV, and there were 4/15 positive samples both (MrNV and XSV). Analysis of histopathology showed that damaged muscle was indicated by the presentation of necrotic tissues with nuclear pyknosis or degeneration of muscle in infected tissues. Based on diagnosis by RT-PCR and histopathological, mass mortality of the giant freshwater prawn in Indonesia is determined to be caused by “white muscle disease (WMD)/white tail disease (WTD)”.

Black tiger shrimp Penaeus monodon post larvae were challenged with Vibrio harveyi and butanol extract of selected marine sponge Aaptos aaptos to determine its antibacterial bioactive potential in vibriosis treatment. Based on the preliminary toxicity study, the A. aaptos butanol extract with concentrations of 31.25, 62.5, and 125 mg/L were selected in the study. Black tiger shrimp post larvae were challenged with V. harveyi at 107 cfu/mL and immersed A. aaptos butanol extract with the concentration of 125 mg/L showed significantly in (P<0.05) decrease mortality of the post larvae treated. Besides at this concentration, V. harveyi population in the rearing water and the post larvae treated decreased compared to control (untreated post larvae). Histological observation indicated that there was no changing on hepatopancreas of the black tiger shrimp post larvae. Based on this result, it is suggested that the butanol extract of A. aaptos is a potential bioactive compounds source in the treatment of vibriosis which may replaced the current antibiotics application.

<p>Usaha perikanan akan mengalami fluktuasi terkait dengan dinamika faktor alam, sedangkan nelayan mempunyai kemampuan yang lentur dan adaptif dalam kelangsungan usahanya. Tujuan utama makalah ini adalah membahas tentang kemampuan adaptasi perikanan purse seine untuk bertahan dari usaha perikanan tangkap. Pemetaan rekaman data sistem pemantauan kapal (VMS) purse seine pelagis kecil tahun 2012 dilakukan berdasarkan kriteria kecepatan kapal nol adalah waktu melakukan aktifitas penangkapan. Daerah penangkapan perikanan pukat cincin pada saat ini telah menyebar semakin luas, tidak terbatas di wilayah teritorial dan perairan nusantara, tetapi sudah sampai ke wilayah Samudera (ZEEI). Jumlah hari laut pada perikanan cantrang kurang dari sebulan memperoleh rata – rata pendapatan nelayan ABK hampir dua kali lipat dari pada ABK pukat cincin yang beroperasi lebih dari sebulan. Rotasi penggunaan alat tangkap di Laut Jawa adalah suatu kondisi yang muncul ke permukaan sebagai sinyal pergeseran populasi ikan dari karakteristik sumber daya yang multi-spesies. Fenomena hasil tangkapan yang tidak tercatat dan dilaporkan menyebabkan pendugaan stok ikan dengan akurat yang rendah akan menimbulkan ketidakpastian dalam penyusunan rekomendasi. Tersedianya sistem pemantauan kapal perlu didukung oleh kegiatan validasi hasil tangkapan yang didaratkan, untuk itu sangat perlu meningkatkan keterlibatkan enumerator dan observer di atas kapal serta penguatan sistem log-book yang sedang berjalan.</p><p> </p><p>The fishing business will fluctuate as a result of high connectivity with the dynamic and nature of environmental factors, in the other side, experience fishers have flexible and adaptive capabilities in order to sustain their business.

Plotting data on recorded vessel monitoring system (VMS) of small pelagic purse seine in 2012 were applied based on the criteria of the zero vessel’s speed as a baseline on fishing activity. Currently, fishing ground of purse seine fisheries been spread more widely, not limited in the territory and waters of the archipelago, but it goes up to the Ocean Region (ZEEI) with day at sea of months. A competitive demersal Danish fishery with average day at sea less than a month is more attractive to fishers. They obtain the average income per crew nearly doubled of working at purse seine with day at sea of more than a month. Rotation on using different type of fishing gears in the Java Sea is a condition that comes to face. This common situation as a signal of shift of having beneficiary of multi-species fish populations. The phenomenon of unreported catches could generate inaccurate estimation of fish stocks and the uncertainty in the management measures to be adviced.

Pemanfaatan sumber daya udang sudah berlangsung cukup lama di perairan Arafura dan status pemanfaatannya sudah berada dalam tahapan yang lebih tangkap (over-exploited). Kondisi yang demikian terjadi karena belum adanya pengelolaan yang tepat akibat kurangnya kualitas kebijakan dan informasi hasil penelitian untuk mendasari kebijakan tersebut. Apabila keadaan ini terus berlangsung dalam jangka panjang, maka akan mengancam kelestarian dan keberlanjutan pemanfaatan sumber daya udang. Untuk mencegah hal itu maka perlu diterapkan opsi-opsi pengelolaan meliputi penutupan daerah/musim penangkapan pada bulan Februari, penerapan kuota penangkapan dengan JTB (Jumlah total tangkapan yang dibolehkan) 39.600 ton per tahun dan melakukan moratorium upaya penangkapan dengan skenario pengurangan 225 armada pukat udang. Keseluruhan opsi kebijakan ini harus ditunjang dengan peningkatan pemantauan, pengawasan dan penegakan hukum. Arafura shrimps resources have been long utilized and to date the status of the resources are over-exploited. To date there are no appropriate management nor involving scientific advice to this fishery. In the long run with the persistence condition the shrimp resource should unsustainably manage and the fishery will collapse. It is urgent to define appropriate management strategies for this fishery based on best scientific finding to the manager to ensure its sustainability. Among other advices are apply closed area for Arafura-sea combining with closed season in February, apply fishing quota with total allowable catch (TAC) for 39,600/yera, no increase of fishing effort, and reduce the number of shrimps trawler for 225 boats. These overall management strategies should fully be supported by increase of monitoring and surveillance with strong law enforcement.

Sejak ikan bilih (Mystacoleucus padangensis) diintroduksi ke Danau Toba tahun 2003, produksi tangkapan ikan bilih meningkat tajam dari 8.500 ton pada tahun 2007 menjadi 45.000 ton pada tahun 2012. Produksi tangkapan tersebut telah berdampak positif terhadap peningkatan pendapatan nelayan dan kesejahteraannya di sekitar Danau Toba. Namun mulai tahun 2013, produksi ikan bilih menunjukkan penurunan yang disebabkan oleh berbagai faktor, seperti tekanan penangkapan yang menggunakan alat tangkap tidak ramah lingkungan, kawasan suaka ikan bilih belum ditetapkan dan dilindungi, permainan harga ikan bilih berukuran kecil dengan permintaan yang tinggi dan masuknya ikan asing invasif (ikan kaca, Parambassis siamensis). Makalah ini membahas strategi pemulihan sumberdaya ikan bilih dan upaya pengendalian ikan kaca di Danau Toba, Sumatera Utara. Since bilih fish (Mystacoleucus padangensis) introduced to Lake Toba in 2003, the catch production of the fish increased sharply from 8,500 tons in 2007 to 45,000 tons in 2012. The catch production has a positive impact on increasing income and welfare of the fishermen around the Lake Toba. However, beginning in 2013, the production of bilih fish showed a decline caused by various factors, such as fishing pressure of the destructive gear, bilih fish reserve areas has not been established and protected, bilih fish of small size intensively catch due to more demanding with high price and the influx of invasive alien fish species of glass fish, Parambassis siamensis. This paper discusses the enhancement and management strategy of the bilih fish resources and efforts to control of glass fish in the Lake Toba, North Sumatra.

Sungai Serkap memiliki sumberdaya ikan yang unik dan beragam. Jumlah jenis ikan di Sungai Serkap pada tahun 2013 ditemukan sebanyak 54 jenis yang sebagian besar merupakan ikan perairan asam. Selain memiliki sumberdaya ikan yang melimpah, Sungai Serkap merupakan habitat ikan merah (Pectenocypris sp), ikan arwana kuning (Scleropages aureus) dan labi-labi (Amyda cartilagynea), dimana arwana kuning dan labi-labi termasuk biota yang dilindungi sedangkan ikan merah diduga ikan endemik dan merupakan spesies baru dari genus Pectenocypris. Walaupun ekosistem perairan Sungai Serkap masih alami namun aktifitas manusia disekitarnya dapat mengancam kualitas lingkungan dan kelestarian sumberdaya ikan di sungai tersebut. Beberapa faktor yang dapat mengancam kelestarian sumberdaya ikan antara lain: i) pembalakan liar, ii) kebakaran hutan, iii) penutupan kanal atau anak-anak sungai, iv) penangkapan pada musim pemijahan, v) eksploitasi jenis ikan tertentu dan vi) belum adanya reservat atau suaka perikanan. Untuk menjamin keberlanjutan sumberdaya perikanan di masa mendatang diperlukan langkah-langkah pengelolaan sebagai berikut: (1) penetapan suaka perikanan, (2) rehabilitasi hutan rawa, (3) penetapan waktu dan lokasi penangkapan ikan, (4) re-stocking ikan arwana kuning dan (5) pengembangan co-managemen. Serkap river has been unique and diverse of fish resources. In 2013, the number of fish that found in Serkap River were 54 species which mostly are acidic water fish. Besides of having abundant resources, the Serkap River is a habitat for red fish (Pectenocypris sp), arwana yellow fish (Scleropages aureus) and labilabi (Amyda cartilagynea), where arwan yellow fish and labi-labi including protected biota while the red fish suspected as an endemic fish and represent a new species from Pectenocypris genus. Although the ecosystems in Serkap River is still natural/clean/unspoiled but human activity around there could threaten the environmental quality and preservation of fish resources in the river. Some factors that could threaten the sustainability of fish resources are: i) illegal logging, ii) forest fire, iii) the closure of canals or creeks, iv) fishing on spawning season, v) exploitation of certain fish and vi) the absence of reservat or fish santuary. Special treatment of fisheries management is needed to ensure the sustainability of fisheries resources in the future as follows: (1) the determination of fish santuary, (2) the rehabilitation of swamp forest, (3) determination of time and location of fishing, (4) restocking of arwana yellow fish and (5) development of comanagement.
