BIOS II is 37 meters long, has the latest equipment In addition, in 2009 several significant international for oceanographic and fisheries research, 15 double projects were completed. At the same time work began cabins equipped with private toilet facilities, lounges, on two new international projects (FP7 and IPA), while laboratories, and the area where the ship can carry out four international projects are still under evaluation, the research includes the Adriatic and the Mediterranean which should be completed by the end of 2010. In the Sea. The new ship was built with joint funds of the last few years, the Institute is increasingly focusing on Institute and the Ministry of Education and Sports of the use of funds from international sources; due to the the Republic of Croatia, so I would also like to take this high cost of oceanographic research our national funds opportunity to thank all former and current employees for research projects are insufficient for conducting of the Institute, who with their work and renunciation regular surveys of the sea. contributed to this project. Besides the acquisition of new ship, in 2009 laboratory In Split, December 2010. facilities for testing the shellfish toxicity were additionally equipped, and now, in addition to HPLC and other Director of the Institute standard equipment, are equipped with the latest LC / Prof. Ivona Marasović MS / MS device. In 2010 experimental hatchery has been completely updated, thus enabling the Institute to be opened to additional opportunities of involvement in the international research projects related to the introduction A Brief History of the Institute The Institute of Oceanography and Fisheries was famous expeditions NAJADAE and CICLOPE (1911- founded in 1930 as the first national institution for sea 1914). In the early 60’s the Institute began with monthly research. The project of Institute’s foundation was measurements of phytoplankton primary production in very seriously approached, so it took 10 years for the the coastal and open sea of the middle Adriatic, which completion of the plan. The first director of the Institute, was the first research of that kind in the Adriatic Sea. the Norwegian professor Dr. Hjalmar Broch was chosen Beginning of the seventies was marked by a new through the international job competition. Prof. Broch activity, focusing on the coastal area. More specifically, moved from Oslo to Split to organize scientific work in rapid urbanization of coastal area has resulted in the the Institute, based on Norwegian experiences. appearance of pollution of certain parts of the coastal Three main aims of the Institute’s activities were also sea, creating the need for development of ecological established: studies.

Broch left the Institute, there was already a joined the Institute of Oceanography and Fisheries. It group of young scientists who went to specialize abroad was reorganized into two separate laboratories of the (to France, Germany, Denmark). The Institute was then Institute and in this form its activities continued until led by the Scientific Council which consisted of several 2006, when it joined the University of Dubrovnik. well-known scientists (Stanković, Vouk, Đorđević and At the beginning of 80’s, the International Summer Hadži). At that time, a systematic research at sea was School “Fisheries Educational Centre for Developing initiated, within which four permanent oceanographic Countries” started and it existed as a three-month stations in the central Adriatic were established. The course from 1981 to 1990, i.e. till the beginning of Institute continued its activities during the Second the War. This period was marked by the successes World War, although with lower intensity. After the War, of the Institute’s scientists in the research of early Prof. Dr. Tonko Šoljan became the director and initiated developmental stages of sea bass, which was extremely one of the most active and successful periods in the important for aquaculture in the whole Mediterranean. history of this Institute. At that time the work on organizing and equipping a The most important project of the Institute in that period computer center began, with intention to establish the was organizing the “Hvar” Expedition (1948-49), an Central Database for the Adriatic Sea. endeavor that by its size and number of collected data In the early nineties the Institute was very actively involved represents even today a unique accomplishment in in educational activities and, within the University of oceanography of the Adriatic Sea.

Based on those data, scientists of the Institute gained new and important insights into the dynamics of the Adriatic waters (known as “Adriatic ingressions”), and insights into the correlation between occasional increased inflow of Mediterranean water into the Adriatic and increased productivity of the Adriatic waters. During the 1960’s, the Institute was especially active through participation in the international expedition MGG (expedition organized in honor of International Geophysics Year), within which the research was performed on the same transects as in the time of the Cooperation with the University of Split and University Within the National monitoring program “The Adriatic of Dubrovnik continued through the establishment Project“(“Projekt Jadran”), the surveillance measuring of joint PhD program in Applied Marine Sciences. system of oceanographic buoys was developed.

It also considers diseases prevention and treatment. In this study, peer reviewed scientific articles, theses and dissertations, symposium proceedings, government records as well as recent books, which published between 1976 and 2013 were used as a source to compile dispersed literature. Bacterial and viral disease problems were investigated during this period in Turkey. Total of 48 pathogen bacteria and 5 virus species have been reported in Turkey. It does mean that all the bacteria and virus present in fish have been covered since every year new disease agents have been isolated. The highest outbreaks occurred in larval and juvenile stages of the fish. This article focused on geographical distribution, host range, and occurrence year of pathogenic bacteria and virus species. Vibriosis, Furunculosis, Motile Aeromonas Septicemia, Yersiniosis, Photobacteriosis and Flavobacteriosis are among the most frequently reported fish diseases. Meanwhile, Vagococcus salmoninarum, Renibacterium salmoninarum, Piscirickettsia salmonis and Pseudomonas luteola are rarely encountered pathogens and might be emerging disease problems. Finally, the current status in fish diseases prevention and their treatment strategies are also addressed.

Interest has centred on two major species sea bream, sea bass, Those are most favourable have been the Aegean and Western Mediterranean coasts. Sea bass and sea bream pruducts have reached to 75,000 tons in Turkey. The gradually increase of this production of fish resulted in serious pathological problems in all countries where intensive aquaculture is practiced. Thus, focus has been placed on fish diseases in these enterprises and their economic and ecological impact. Especially, parasitical diseases have become increasingly visible during the latest decades in connection with the development of aquacultural industries troughout the world. In this study, various studies were carried out in different time about parasites of cultured gilthead sea bream ( Sparus aurata L.) and sea bass ( Dicentrarchus labrax L.) in Turkey and their treatment were investigated. Different species such as Trichodina spp., Costia spp., Amyloodinium ocellatum , Furnestinia echeneis, Microcotyle chrysophrii, Diplectanum aequans, Caligus minimus, Lernanthropus kroyeri and Ceratothoa oestroides were reported on the gills of sea bream and sea bass in these studies.

Introductıon The Cymothoidae is a family of ectoparasitic isopods found on body, fins, or inside the buccal or branchial cavities of numerous freshwater and marine fish species. They are protandrous hermaphrodites (Bariche & Trilles, 2005). Several studies were carried out to determine the effect of the cymothoids on host fishes in aquaculture (Mladineo, 2002; Horton & Okamura, 2003; Čolak et al., 2017). Mladineo (2002) found a significant decrease in weight of sea bass infested with C. oestroides. Horton & Okamura (2003) searched the blood parameters of cultured sea bass which was infected with C.

However, the spatial concentration of coastal pelagic fisheries, combined with unexpected increases in the abundance and biomass of selected pelagic species within coastal Marine Protected Areas (MPAs), suggest that the population dynamics and/or behavioural traits of coastal pelagic fish stocks may be structured at much smaller spatial scales. I have adapted two existing research techniques - baited remote underwater video (BRUV) and otolith chemistry - to investigate habitat associations, population structure and movement patterns of selected pelagic species at small spatial scales (100s of metres to kilometres) in two MPAs in south-east Australian waters. I combined a novel midwater BRUV technique with in situ hydrographie measurements to determine the distribution, abundance and habitat associations of selected pelagic species {Carcharhinus galapagensis, Seriola rivoliana, S. lalandi, Tractiurus novaezelandiae and Scomber australasicus) at Lord Howe Island and Jervis Bay Marine Parks, and identified areas of preferred 'habitat' for each species which were characterised with reference to hydrographie characteristics and/or small-scale oceanographic processes.

This represents the first record of N. phaiopleura in finfish mariculture. The species is the third cymothoid isopod from maricultured fishes in Japan. The infected fish had a large hemorrhagic wound caused by N. phaio- pleura at the attachment site. Thunnus orientalis is a new host of the isopod. No cy- mothoid infection has so far been reported from wild individuals of T. orientalis that swims at high speeds in the oceans, and the observed occurrence of N. phaiopleura on this fish species is regarded as unusual under confined mariculture conditions. The hosts and geographical distribution records of N. phaiopleura in Japan are reviewed.

In this study, we used visual census to record grey mullet aggregations at fish farms in the west- ern Mediterranean Sea. We also mapped the movements of 2 species (Liza aurata and Chelon labrosus) between farms and adjacent coastal fishing areas, using acoustic telemetry. Grey mullet were frequently observed in the vicinity of the aquaculture cages and represented an important abundance and biomass at the farms. The presence and swimming depth of the tagged mugilids at any of the farms were neither significantly related to the time of the day nor the feeding period, except for C. labrosus, which showed a tendency towards deeper waters (~15 m) during feeding peri- ods. Some of the tagged fish stayed in the vicinity of the farms for longer periods and also moved fre- quently to other farms and nearby commercial fishing areas.

Nevertheless, the parasitic effects on fish body condition Mouth parasite have been studied only in a few Ceratothoa species, particularly those living in the Mediterranean and Australian Isopoda waters. Findings from these previous studies suggest the hypothesis that effects of parasitism by Ceratothoa Host body condition species are benign on native host condition in the wild. In this study, to test this hypothesis on another Kyphosidae Ceratothoa–fish relationship in different region, we examined the effects of Ceratothoa arimae on the body Izu Island chain condition of the yellowstriped butterfish, Labracoglossa argenteiventris, a commercial fish important to local fisheries particularly in the remote islands of Tokyo, Japan.

    DISEASES OF AQUATIC ORGANISMS Vol. 57: 97–101, 2003 Published December 3 Dis Aquat Org Life cycle of Ceratothoa oestroides, a cymothoid isopod parasite from sea bass Dicentrarchus labrax and sea bream Sparus aurata Ivona Mladineo* Institute of Oceanography and Fisheries, Laboratory of Aquaculture, PO Box 500, 21000 Split, Croatia ABSTRACT: Ceratothoa oestroides (Risso, 1826) (Isopoda: Cymothoida) is a protandric hermaphro- dite parasite on a wide range of wild fish species. In recent years it has become a threat to cage- reared fish facilities, where high fish density provides optimal conditions for transmission. Its impact on fish health and economical gain is significant, varying from growth retardation and decreased immunocompetency to direct loss due to mass mortalities of juvenile fishes. Because of the sheltered location of the parasite in the buccal cavity of fishes, chemotherapeutics are ineffective. An under- standing of the C. oestroides life cycle and its behavioral mechanisms could prove constructive tools for the prevention and control of infection. This study describes the reproductive cycle of C. oestroides experimentally induced in different fish hosts and temperature regimes. Sea bream larvae Sparus aurata and 1 yr annular sea bream Diplodus annularis were chosen as experimental models, and were held at 22 and 19.5°C, respectively. The reproductive cycle of S. aurata was not completed within 4 mo (at which point the last larva died of severe anemia and respiratory distress), while that of the annular sea bream was completed successfully after 1 mo.
