Abstract:

Aquaculture is doubtlessly the branche of the food sector which is most important, at least in the following 20-30 years, for different reasons:More and more aquaculture has to compensate the restrictions in the maritime fishing sector. Due to the predicted growth of the world population by some billion people it is inevitable to use aquaculture for the additional protein demand. Wild catch is even now already decreasing. Key issue in the discussion how to feed the world is sustainability. Aquaculture is unbeatable in topics like food conversion rate, carbon footprint, carefull use of resources in general. Sustainability is the magic word. The definition Aquaculture by FAO is accepted worldwide:”…farming of aquatic organisms…” this includes “rural aquaculture” as well as “industrial monoculture” . The broad variety of aquaculture is also reflected in the wide range of taxonomic criteria. Such as “degree of commercialization”, “extensive-semiintensive-intensive”, not to forget algae production, or aquaponics, just to name a few. In this presentation the role of European aquaculture (E28) is discussed on different Member States, MS using Germany in detail. The EU28 situation is compared with NonEU countries and the world wide situation . Additional functions of aquaculture are discussed exceeding the purpose of growing fish or water organisms, as e.g. ecosystem services.There are lot of areas of conflict, having an adverse effect to the development of aquaculture. Although the ecological- and other advantages are undisputed, aquaculture in Europe needs support  by politics, science, and most important entrepreneurs. A study is presented, showing the differences in twelve key issues between EU 28 (eg. Germany) and Non EU countries (Turkey). Internal barriers due to administration, environment protection, NGOs are discussed, as well as the difficulty for EU Aquaculture to stabilize its position on the world market. Particular emphasis is given to the topic “level playing field” and to the question what sense makes a European financial support , given to Aquaculture having the long term development in mind.Some examples will show the wide range and how deep sustainability can be implemented in freshwater aquaculture using modern technologies with the clear commitment to it of the entrepreneur. The importance of Eco labels is discussed in relation to the sustainability philosophy of the employers.Finally a “to do list” of producers, addressed to RTD and politicians is presented to point out the criteria to be fulfilled in order to use at least partly in EU member states the great potential which is seen worldwide in Aquaculture

Abstract:

In 1822, when the Briton Francis Hamilton first described a certain small, longitudinally-banded fish as Cyprinus rerio(today Danio rerio), from the Kosi River in India and assigned it a so-calledDanio-division (named after the Bengalese nameDhani), he can have had no idea of the popularity this little cyprinid would eventually achieve. It was first imported for the aquarium hobby in 1905, and christened “zebra danio“, the name it still bears today. In universities and research laboratories it was established in the early 1980s, as “Zebra Fish”, and became a model organism for studies of vertebrate development, developmental biology, and some human genetic diseases, after Streisinger’s pioneer work at the University of Oregon, with wild fishes collected by Bleher in Assam. With the result that15 years before Dolly the Scottish sheep achieved fame, Zebra Fish had been cloned at this University, being the first vertebrate cloned in history. Today over 5,000 researchers in 450 labs throughout 30plus countries study Zebra Fish. And in this oral presentation Bleher will not onlytalk about recent successes with this 3-5cm long fish, but also about other tiny fish species with amazing scientific underestimated results inseeking solutions to diseases which affect humans  …

Session Introduction

Helmut Wedekind

Bavarian States Research Center for Agriculture, Germany

Title: Recirculating aquaculture – Status and developments
Speaker
Biography:

Helmut Wedekind has completed his PhD at the age of thirty one years from Göttingen University on postdoctoral studies on intensive catfish farming. He is the director of the Institute for Fisheries, part of the Bavarian States Research Center for Agriculture in Starnberg, which is a research and education center for fisheries and aquaculture. He has published papers in reputed journals and in national fisheries and aquaculture journals. Moreover he is a lecturer at the Technical University of Munich and other German high schools in the field of aquaculture

Abstract:

The cultivation of different aquatic organisms in recirculating aquaculture systems (RAS) is practiced since decades in Europe, the USA and other countries worldwide. Due to different limitations of open aquaculture systems (e. g. ponds or net cages), and restrictive regulations of water supplies and waste, water reuse is becoming more and more relevant. Whereas heated RAS in isolated buildings were already established in the eighties, the increasing use of the recirc-technology in cold water aquaculture (e. g. salmonid farming) is a relatively new development. When compared to traditional aquaculture, both - warm water RAS and cold water RAS - are characterized by a comparatively sophisticated technology and high operating efford and capital costs. Consequently, mangers of RAS are in need for a thoroughly base of specific know-how. For successful RAS farming fundamental knowledge in the field of biology, production technology, mechanical and biological filtration, stock management, feeding, health management, controlling, biosecurity, and economics is essential. All this has to be considered for warm water RAS, which accomplish high recirculation rates, and cold water RAS with a higher daily water exchange. Actually, the production of different tropical fish and crustaceans, as well as species cultured under temperate temperature – including freshwater and marine organisms – recently is rapidly developing

Abstract:

A overview of freshwater fish diseases is presented, divided in viral, bacterial and parasite aetiology. The different disease patterns are described, underlined with slides showing typical symptoms.The relevant EU regulations, like directives and laws within the EUanimal/human health philosophy is presented and will be discussed. Following core topics are: The directive 88/2006, including five Categories of disease free level. Definition and handling of exotic and nonexotic notifiable diseases.  The national implementation of the framework, differences between memberstates “Traces”, a method to prevent spreading diseases by transporting fish to member states, including a flowchart for administration as well as for fishfarmers.  A special part will discuss the situation of “new” diseases, not yet in the focus of the framework, where partly is even not yet  a standardized diagnostic or treatment available. E.g. CEV, Sleeping disease trout, strawberry disease. What will change when the new Animal Health Law (AHL) comes into force? The necessity of vaccines within a biosecurityplan instead of Antibiotic use is discussed especially in the light of the new EU legislation.  What changes in the cascade of the new AHL , when you need a drug for a treatment when there is nothing direct meant for the disease in the relevant  fish species. In the final part the problems of fishfarmers using the framework TRACES and RL88&2006 will be discussed, and the demands are formulated to have a competitive basis on the european-  and worldmarket.

Abstract:

The present study investigated the effects of propolisand vitamin E supplementation in diets of juvenile rainbow trout subjected to two different flowrates (0.9and 2.1 L min−1) on growth performance, and vitamin A, C and E concentrations in tissues as well as malondialdehyde (MDA) levels. Juvenilerainbowtroutwere fed withdietscontaining 10 and 30 g propolis kg−1, 60 mg kg−1 vitamin E (Rovimix E-50 adsorbate; min.%50 dl-α-tokopherlyacetate) andwithoutsupplementedbasaldietfor 12 weeks. Weightgain (WG) in the C groupwassignificantlylower (P < 0.05) than P10, P30 and E60 groups at bothflow rate treatments. At 2.1 L min−1, specificgrowth rate (SGR) in the C group was significantly lower (P < 0.05) than other groups, but at 0.9 L min−1, SGR of fish didnot differ among thedietsgroups (P > 0.05). Survival rate (SUR) was higher in propolis and vitamin E supplemented dietgroups (P < 0.05) than control diet group at 0.9 L min−1. Fish fed on diet E60 had higher (P < 0.05) tissue vitamin E concentration than fishes fed on other diets groups. Vitamin C concentration in rainbowtrout tissues was significantly affected by the 30 g propolis supplemented diet group (P < 0.05), followed bythe 10 g propolis supplementeddiet group (P < 0.05). MDA level of E60 group was found significantly decreased instead of different than other groups (P < 0.05). The results of Student's t-test revealed that WG, SGR, SUR values, vitamin (A, C, E) concentrations and MDA levels of tissues were negativelyaffected by0.9 L min−1flow rate treatment in juvenile rainbowtrout.

Abstract:

The present study was carried out to evaluate the long termfeeding (4 months)of crude palm oil-based (CPO) diets to hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus). Five isolipidic (16%) and isoproteic (50%) practical diets were formulated to contain differentreplacement level of fish oil with crude palm oil. A control diet was supplemented with 100% fish oil labelled as FO and the rest of the experimental diets were labelled as 25CPO, 50CPO, 75CPO and 100CPO indicating 25, 40, 75 and 100% replacement of fish oil with CPO.The initial fish (approximately 200 g) were randomly distributed into groups of 30 fish in square cages (2.0 m depth and 1.5 m diameter) in the sea. The triplicate groups of hybrid grouper were fed once a day at apparent satiation level. Growth measurement was carried out on a monthly basis.At the end of the feeding trial, fish fillet were subjected to sensory evaluation analysis.  No significant differences (p>0.05) in terms of growth among fish fed with various experimental diets with weight gain and SGR ranging from 171.43 % (75CPO) - 181.63 % (50CPO) and 0.83±0.01-0.86±0.02%/d, respectively.Survival rate of fish were considered very high during this 4 months feeding trial with values above 93%.Based on the 5-point hedonic scale of acceptance test, all fillets were neither like nor disliked by the panelists.There is no particular trend of acceptance in all attributes among the fish fillets implying fillets of fish fed with CPO are well received by the consumers.

Abstract:

In this study, sage, thyme and clove oils were evaluated as a glazing material for rainbow trout (Oncorhynchus mykiss) frozen. One percent sage, thyme and clove oil solutions were used for glazing. Water-glazed (WG) and nonglazed (NG) rainbow trout fillets were used as controls. Fish fillets were glazed and were stored in a freezer at -18C for 6 months. Samples were analyzed at 1, 2, 3, 4, 5 and 6 months for moisture content, total volatile basic nitrogen, thiobarbituric acid, peroxide value, free fatty acids and sensorial quality. It was determined that glazed samples had higher moisture content compared to NG trout fillet after 6 months storage. Essential oils were effective in controlling lipid oxidation in rainbow trout fillet (P < 0.05).

Jiashou Liu is currently professor in State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, China 

Abstract:

Lakes are important for stock enhancement fisheries in China. More than 10 species are stocked into lakes to increase production. The most common species stocked are planktivorous silver carp, bighead carp, and herbivorous grass carp. However, stocking of silver carp and bighead carp has resulted in eutrophication because of manure application. Stocking of grass carp has resulted in the disappearance of macrophytes. In this paper, two case studies in two lakes of the Yangtze River basin in China are introduced. One case is the replacement of low valued carps by high valued mandarin fish and Chinese mitten crab, resulting in better economic benefits and water quality in Wuhu Lake, Hubei Province. The stocking rate of mandarin fish is determined by food consumption rates, which is mainly related to water temperature and fish size, and prey fish productivity, which is mainly related to mean biomass of prey fish, production/biomass ratio and temperature. The bioenergetics model of mandarin fish is established to predict the growth and consumption of prey fish in stocked lakes. The stocking model of mitten crab in culture-based fisheries is also established based on biomass of macrophyte coverage, benthos biomass and ratio of Secchi depth to mean water depth in lakes. The other case is stock enhancement of combined piscivorous fishes based on fish community structure, resulting in better water quality and recovery of macrophyte biodiversity in Kuilei Lake, Jiangsu Province.

Abstract:

In order to investigate the effects of stocking density stress on the physiological and immune responses of Atlantic salmon in RAS, five stocking densities (6, 9,15,21 and 24 kg/m3) groups of Atlantic salmon (180D, 1-1.5kg) were reared in five square concrete ponds (90m3). The mortality was obviously affected by stocking density and the content of DO decreased following the density increased, NH3/NH4- showed a positive correlation with density of CO2 content. The specific growth rate, final weight and weight gain in the HSD group were significantly lower than those in the LSD and MSD groups. T3 and GH showed significant decrease with the increase of the stocking density. The content of cortisol in HSD group was significantly differentiated from MSD and LSD groups after 40 days, and then the content among the five groups were nearly equal after 130 days. Our results also showed that the levels of leucocyte numbers and hemoglobin expressions were positively correlated with stocking density after 100 days. The level of lysozyme expression in liver and kidney of high density group began to decline and rise since 130 and 190 days, respectively. GOT activities showed no significance before70 days, and group A increased quickly after 100 days. The level of serum GPT activities showed the similar changes with GOT. According the our results in the this study, the stocking density of 30 kg/m3 was considered as the node in RAS caused by density stress.

Zhongjie Li is currently professor in State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, China

Abstract:

It is acknowledged that China is the mainstay in global aquaculture, contributing for example 65.7 (of 76,321,310 t) and 63.6 (of 38,994,913 t) percent to total global and freshwater aquaculture production, respectively in 2011, significantly increasing the corresponding contributions from36.1 and 38.5 percent of the global total (7,359,881 t) and global freshwater (2,342,706 t) aquaculture production in 1989. Overall,aquaculture production in China in turn has enabled to reduce our dependence on food fish supplies from a hunted to a farmed origin, like all the other staples. It is evident that though inland aquaculture is practiced in most provinces of China, the great bulk of it occurs in the area that lies approximately between 110 to 120 °E and 19 to 35 °N. Importantly, the provinces in the Yangtze River Basin accounted for 66 percent of the inland aquaculture production in China.The major changes that are likely to occur in freshwater aquaculture in Yangtze River Basin in all probability will be associated with minimizing environmental perturbations arising from aquaculture practices. In regard to the trends of freshwater aquaculture in Yangtze River Basin, two aspects can be expected. Firstly, it is the stricter use of natural freshwaters including lakes, reservoirs and rivers for aquaculture.Secondly, in compensation for aquaculture production losses from natural water bodies, more attention will be paid to controlled water bodies

Abstract:

Assessment of petroleum Hydrocarbons (PHC) contamination was carried out along with the water samples of Egyptian Lake Temsah, Suez Canal. Disease risk probability due to PHC contamination using cytochrome p4501A1 and glutathione S-transferase genes expression by RT-PCR in Gafrarium pectinatum bivalve in association with the investigation of parasitic infection were applied. Results indicated 0.85% µg/l petroleum Hydrocarbons contamination of Lake Temsah waters. Obvious increase in the cytochrome p4501A1 and glutathione S-transferase mRNA level was observed in response to Hydrocarbons contamination. 60% Marteilia refringens parasite infection was reported which may be correlated to PHC contamination.This study provides a basis for studying hydrocarbon detoxification processes in marine bivalves, especially Gafrarium pectinatum

Tipsuda Thongbuakaew has completed her PhD at the age of 30 years from Mahidol University. She is the lecturer of School of Medicine, Walailak University. She has published 3 papers in reputed international journals

Abstract:

We demonstrated for the first time the existence and distribution of kisspeptin-like peptides (Kiss-l) and their receptors in the central nervous system (CNS) of the giant freshwater prawn, Macrobrachium rosenbergii, and that these peptides could induce the oogonial proliferation, ovarian maturation, and spawning. Using immunohistochemistry, kisspeptin1-like-signal (Kiss1-l signal) was detected in the neurons of clusters 6, 11 and 14/15 and also in olfactory neuropil (ON). Kisspeptin2-like-signal (Kiss2-l signal) was observed in clusters 6, 9, 10, 16 and 17 as well as in the anterior and posterior median protocerebral neuropils (AMPN/PMPN), ON, central body (CB) and protocerebral bridge (PB) and olfactory globular tract (OGT). In the subesophageal (SEG) and thoracic ganglia (TG), both Kiss1-l and Kiss2-l signals were detected in some neurons of dorsolateral cluster (DLC), ventromedial cluster (VMC) and also in fibers of associated neuropils. In abdominal ganglia (AG), Kiss1-l signal was detected in some neuronal clusters, whereas Kiss2-l signal was detected only in fibers of the AG. Functional bioassays demonstrated that both Kiss1- and Kiss2-treated prawns showed significantly shortened ovarian cycle (16±1.63 and 22.86±1.07 days) compared with the control (36±2 days). Moreover, both Kisses significantly increased the numbers of oogonial proliferation and spawned eggs, while the percentages of fertilized eggs in all treated groups were not significantly different from the control. These findings suggest that Kisses are highly conserved peptides that may also exist in the prawns and control their oogonial proliferation and ovarian maturation.

Abstract:

This study was conducted at the College of Fisheries Fish Processing Laboratory, Cagayan State University, Aparri, Cagayan from August to October 2003. It aimed to determine the effect of preservatives (citric and sobic acids) on the shelf-life of spiced-dried fish sticks wrapped with waxed paper. It was limited to the use of skipjack tuna (Katsuwonus pelamis). Sensory and physical evaluation on color, taste, and moisture content changes of the product were done. Microbiological examination (mold count) of the product was also undertaken. Results of the study revealed that products treated with .02% sorbic acid had the longest shelf-life at ambient temperature which was 35 days. The product showed lower moisture absorption and lower mold count as the storage days progressed. Molds that grew on the product were identified to belong to the genera Mocor aspergillus and Rhizopus.

Title: Colour preferences of juvenile turbot (Scophthalmus maximus)
Speaker
Biography:

Xian Li has completed his PhD at the age of 26 years from Institute of Oceanology, Chinese Academy of Sciences. She has published more than 16 papers in reputed journals

Abstract:

The background colour of aquaculture tanks was ordinarily chosen according to practical experience and/or observations of the fish behaviour and growth rates achieved. However, some farmed species, such as fish, are sentient and can make choice, showing preferences to environments. In the current study, a self-referent colour preference device was developed and the self-referent colour preference of farmed fish investigated. In experiment 1, the background colour preference of juvenile turbot cultured under a grey background for >3 months post-incubation was evaluated. Based on these results, in experiment 2, juvenile turbot were adapted to blue, pink, white and black backgrounds for 50 days and their preferences established. Meanwhile the growth rates, feed intake and the metabolic rates (including oxygen consumption rate and ammonia excretion rate) were evaluated. We found that turbot farmed under a grey background, or after long-term white, blue, pink and black colour adaptation, always displayed a preference for a white background and a dislike for black, red, or brown backgrounds, although their body colour was greyish. Long-term adaptation influenced the frequency of juveniles selecting white, black, pink or blue backgrounds. They showed the highest growth rate, feed intake and the metabolic rates under the blue and white colours, and the lowest under the black colour in accordance with their preferences. While how turbot made their decisions on self-referent colour preferences in a short time needs more investigations. These results indicate that dark colour is not suitable for turbot culture in view

Mossamat Rashida Akter is currently working as visiting scholar in James Cook University, Australia

Abstract:

The aim of the present study was to assess the current status and future potential of the fresh water and marine aquaculture industries in Far North Queensland 2015 using semi-structured interviews and administered questionnaires to elicit information from aquaculturalists in the region (n= 5 comprising 4 barramundi farmers and 1 Queensland grouper farmer).The results revealed that despite aquaculture undergoing rapid growth and transformation around the world, the industry in Far North Queensland has a long way to go to reach its full potential and to compete with other countries in the region in terms of technology and in updating government policy and legislative frameworks to facilitate the expansion of sustainable aquaculture. Those interviewed stated that here have been no applications for new aquaculture farms for last 15 years in Far North Queensland, and that the lack of development may be attributed to the following factors: the regulatory burden is high; the standards imposed by regulators do not reflect the true impact of the industry and are in need of review; that the industry has difficulty attracting, training and maintaining appropriately qualified labour; and, that the industry needs to modernise and diversify. Nonetheless, most of those interviewed are optimistic about the future of their industry, provided these matters are urgently and constructively addressed.
