    Pogonoski 3 Melody Puckridge 3 Stephen J. It commissions collaborative research between Australian and developing-country researchers in areas where Australia has special research competence.

    Where trade names are used, this constitutes neither endorsement of nor discrimination against any product by ACIAR. The series is distributed internationally, with an emphasis on developing countries. The Australian Centre for International Agricultural Research ACIAR strongly supports fisheries research in Indonesia and understands the need for regional field guides for assisting fisheries scientists with species identification.

    This comprehensive field guide, written in both English and Indonesian, is the first of its kind to include all of the bony fishes marketed in Indonesia. It should improve fisheries data collection by enabling researchers to accurately identify the species being landed and providing a better understanding of the level of exploitation of the various marine fishes.

    ACIAR would like to express our thanks to those who have worked so hard to develop this comprehensive field guide. Identifikasi jenis secara akurat di tempat pendaratan ikan sangat penting bagi pengelolaan perikanan yang efektif.

    ACIAR telah mendanai proyek ini dari tahun sampai , bekerjasama dengan lembaga ilmiah perikanan di Indonesia dan Australia untuk mengembangkan pemahaman baru dan kerangka kerja kebijakan perikanan laut di Indonesia.

    Salah satu tujuan dari proyek ini adalah untuk memberikan informasi baru yang singkat dan rinci dalam bentuk buku panduan lapangan tentang jenis ikan yang dieksploitasi di kawasan ini.

    Buku panduan lapangan yang lengkap ini ditulis dalam bahasa Inggris dan Indonesia adalah yang pertama untuk melakukan identifikasi jenis ikan bertulang yang dipasarkan di Indonesia. Hal ini juga akan meningkatkan pengumpulan data perikanan di masa yang akan datang yang memungkinkan peneliti untuk secara akurat mengidentifikasi jenis yang didaratkan dan memberikan pemahaman yang lebih baik tentang berbagai tingkat eksploitasi ikan di laut.

    ACIAR ingin mengucapkan terima kasih kepada mereka yang telah bekerja keras dalam penyempurnaan pengembangan buku panduan lapangan ini. The physical seascape is unique in consisting of an elaborate series of shelves, volcanic mountain chains and deep-sea trenches.

    This, together with its complex geological history, has resulted in Indonesia having the greatest marine biodiversity in the world. For example, according to data from the Food and Agricultural Organization of the United Nations FAO , the reported fisheries capture production for Indonesia in exceeded 5. Indonesian fisheries use a variety of methods to catch bony fishes, such as gill nets, longlines, handlines, spears, trammel nets, fyke nets, seine nets, traps and bottom trawls.

    Generally, the entire catch both target and bycatch species is retained. Indeed, more than half the coral reef fish species occurring in the Indian and Pacific Indo-Pacific Oceans are found in Indonesian seas. As a result, the diversity of fishes, particularly coral reef species, caught by the various fisheries is extremely high.

    The Solor and Alor Islands

    Indonesia has a long history of ichthyological exploration dating back to French and Dutch explorers in the early 19th century. More than 12, fish specimens were collected by Bleeker and catalogued in various European collections, particularly the Natural History Museum in Leiden, Netherlands.

    Despite the large amount of information available on reef fish species and a relatively good understanding of the fishes occurring in Indonesia, very limited accurate data are available on 12 the fish species exploited by fishers in the region.

    Included in the project was a component to survey the fish landings at various fish markets within the Indonesian Fisheries Management Zone number WPP on the islands of Java, Bali and Lombok.

    This is the most populous region of Indonesia, with a very high concentration of fisheries and ports. With the latest project, nine surveys were conducted at seven fish landing sites to determine the species composition of bony fishes in the landings and established a reference collection of almost 3, species. These surveys led to the production of this field guide. A guide to the families of bony fishes encountered is provided, as well as photographs and diagnostic characters of species.

    This book, in conjunction with the earlier one on sharks and rays see above , will enable users to identify all the commonly seen market fishes of Indonesia. The ACIAR-funded projects have provided a better understanding of the fish species exploited by fishers in the most populous regions of Indonesia.

    The two major mountains, Kolana 5, feet [1, metres] and Muna 4, feet [1, metres] are both old volcanoes. Alor is broken up by steep ravines, with only one plateau and some small coastal plains. Alor Island has two rivers, the longer one Waelombur is 30 km long and the other, Bukapiting is 25 km long. Most of the people practice traditional religions, except for some Christian communities along the coasts and some Muslims. Festive occasions often involve exchanges of pigs, gongs, and mokos, cast-bronze kettle drums of unknown origin.

    The waters around the islands are known for their strong currents, particularly in the relatively narrow strait between Pantar and Alor and also between Lembata and Pantar. With each tide large water masses are pushed through the straits causing strong upwelling and treacherous currents of six knots and above.

    Sea water flows from north to south on a rising tide and in the opposite direction when the tide ebbs. There are 14 languages used in the island group. At present, however all people are also literate in Bahasa Indonesia.

    The level of basic education is considered high and Alor has the highest level of literacy in NTT. Generally speaking, there are five or six month s consecutive wet months and three or less consecutive completely dry months. However, Alor s annual rainfall is higher and rains intermittingly every month due to the mountainous topography. The small islands on the other hand may remain dry for as long as eight or nine months of the year. The periods March to June plus October and November are considered periods of relatively calm weather.

    Average minimum air temperature ranges between C with a peak diurnal temperature of 34 C during October and November, the hottest months of the year. Northerly winds indicate the onset of the wet season with strong westerly winds occurring in December and January.

    Strong easterly winds take place during July, August and September Photo 5. Teluk Kebala, Alor, August raining in the dry season.

    Boats however, are the dominant transport mode in the area with large ferries such as the PELNI and truck ferry fleets visiting ports across East Nusa Tenggara and beyond.

    Access to all the smaller coastal villages on the islands can be achieved using the numerous interisland ferries or smaller wooden vessels from one of principal island ports such as Larantuka east Flores , Menanga Solor , Terong Adonara , Lewoleba Lembata , Balauring Lembata , Baranusa Pantar and Kalabahi Alor.

    Roads in the centre of principal settlements on each of the islands have been asphalted to an extent and the road condition generally deteriorates on leaving. Motorbikes are the preferred mode of transport, small public vehicles serve the villages and occasionally large trucks will carry passengers. Constant power supply and cellular hand phone signal is available in all main towns with only the remotest villages without telecommunication capabilities and continue to utilize generators for electricity each evening.

The total survey effort time would be very much higher to include the period preparing for the survey and the time incurred writing the report. The vessel s safety and well-being of everyone on board was paramount during the survey. One stipulation adhered to continuously was that the vessel was securely moored by sunset each day, no night sailing.

    A schedule had been organised beforehand indicating the route, target villages to be visited and duration.

    This worked well and each evening the next day s itinerary was planned, a joint decision between the Captain and survey team. Table 3 on the following page gives an overview of the villages visited, primary data status and GPS points of jetties where applicable.

Usually, the eggs are collected the following morning after being laid the previous night and consumed locally. If a large settlement or town is nearby, turtle eggs are taken to the local market and sold. In Kalabahi, Alor, turtle eggs are purchased by the Chinese community mainly who can buy three eggs for Rp Only Pulau Marisa, Pantar has implemented a policy whereby the islands residents are not allowed to disturb either turtles or their nests.

    Desa Watuhari, Solor Island continues to take eggs but do not disturb the turtles following efforts by WWF during the socialisation program in During the survey when visiting villages and houses no evidence such as turtle carapaces, bones or meat were observed. Additionally, it was unclear whether the reason for this was that no turtles had been taken or simply all parts of the animal had been either consumed or sold.

    Clear species identification by interviewees proved problematic even when shown illustrations see annexes. Figure 2 and table 5 on the following pages display the information collected from interviews. Additional information was obtained suggesting turtle catching locations and nesting sites though no species were identified see table 4.

    Northeast side of Lembata has a notable extensive white sand beach that appears almost deserted from sea between 08 o S, o E and 08 o S, o E. Closer inspection was not possible due to the surf however, this location seemed very promising indeed. One hundred and thirty-three turtles were observed independently entering the sea without being disturbed by the survey team, the Head of the village Kepala Desa or his associates.

    At that time, the team s initial assumption was that the turtle hatchlings were Hawksbill Eretmochelys imbricata due to the dark colouration on both sides of the animal.

    However, later using two turtle identification keys 3 indicated that the hatchlings were probably Olive Ridley Lepidochelys olivacea from the arrangement and number of carapace shields.
