Aquaculture, with the ever-increasing seafood consumption per capita versus the decrease in wild caught supplies, plays a significant role in food management and more significantly, is poised to play a far greater role in the future. Hence, delivering commercially viable sustainable facilities for aquaculture is a challenge that needs to be addressed and mastered.
For the EU, the delivery of a Sustainable Aquaculture Facility needs not only to address the Environmental, Economic and Social Parameters, but rather navigate a plethora of EU Directives and Legislative Hurdles, although lately the EU’s Blue Growth Strategy has clarified the labyrinth that is permit acquisition.

Delivering Europe’s largest commercially viable, Land Based BIOFLOC Dominated RAS Facility for the growing of the sub-tropical Black Tiger Prawn Penaeus monodon, has been an exercise in managing key environmental challenges as well as addressing and respecting wildlife protection requirements under the Birds and Habitats Directives (NATURA 2000) as well as adhering to the regulation of the use of alien and locally absent species in Aquaculture.
For the investors, the financial viability of the project needed to be addressed as to make it an attractive investment with market realistic ROI. This was achieved with the use of finite RAS technologies, in conjunction with EU funding for the creation of greatly needed employment positions in one of Europe’s lowest socioeconomic areas, Thesprotia Greece.
The Europrawn Greenhouse enclosed Biosecure RAS facility allows for year-round production of a sub-tropical species in Europe and in our presentation, we expand in the facility, its technology and the environmental footprint, as well as animal health management attained via the use of SPF stock and the development of the internal breeding program.

Title: Restoration of polluted environment and ecology of marine sediments by reducing Acid Volatile Sulfides


After graduated from high school, he spent about 25 years studying in various fields through many experiences in various professions. Since then, research has been conducted on the development and field application of catalysts for reducing volatile sulfides of acid in polluted sediments in coastal oceans, and in fields related to marine aquatic products now Man Gil Ahn working Researcher in Hainet Korea Corporation Ulsan  country will be South Korea


In the marine environment, pollutants continue to flow from land to the sea, and pollutants settle in sediments under the sea, and the environment of coastal marine ecosystems decomposes due to the increase in pollutants. Incapacitated sediments create an imbalance in the ecosystem in which marine life lives due to increased anaerobic conditions. In addition, fish excrement and sedimented feed generated in coastal marine fish farming are sources of sediment pollution and cause ecological problems for sediments. Over the years, methods for restoring the ecology of marine sediments have been contaminated by physical, chemical, biological, and various methods of dredging marine sediments. Restoration is performed by a specific method. (sediment dredging, sand, zeolite, limestone, fly ash, furnace slag, red mud, assembly of inorganic materials including, Coal Ash, Iron oxide, shells, adsorption of microorganisms to adsorptive substances, etc.) Coal ash, which is generated by burning coal from a coal-fired power plant, is discharged and landfilled in the ground.
We have developed and applied it as a basis for the reduction of land-based waste generated by the reduction of landfills in the ground and the restoration of the ecological environment of polluted marine sediments. The composition of coal ash resembles marine sediments, reburning coal at high temperatures and recycling it as a porous ceramic product. We have demonstrated this by applying it widely to the fields of marine and fisheries and land reservoirs.

Title:  Aquaculture and Marine biology is the major industry for the development of health, basic need of daily life, create employment, generate income, stronger economy, reducing financial crises, global Poverty and hunger in the developing countries of the world particularly in south Asia.


Mr. Muhammad Usman, Former Director General of Agricultural Research System, Government of Pakistan who retired from service after a spotless career of about 32 years with senior level experience on research and development of integrated agricultural production, industries, Agriculture & Horticulture and bioenergy on a sustainable way.He is consider as the senior most scientist in the world, always participated in the international conferences as a plenary speaker, keynote speaker, renowned speaker, organizing committee member as well as moderator of the conferences around the world. Mr. Usman established “Prominent Agro Based Industries, Agro Based Industries and Consultancy SDN BHD†in Malaysia and “Foundation for Rural Development in Pakistan, with primarily aims to work on integrated agricultural project for Rural Development through improvement in agriculture and consultancy services to the formers at Malaysia.


The aim of presentation consists of aquaculture, marine biology, health, daily use of life, employment, income, economy, crises, poverty and hunger were studied and reported that aquaculture and marine biology is the major industry for the development of health, basic need of daily life, create employment, generate income, stronger economy, reducing financial crises, global Poverty and hunger in the developing countries of the world particularly in south Asia.  The study reported that Aquaculture is the breeding, rearing and harvesting of fish, shellfish, plants, algae and other organism in all types of water environments including ponds, river, lakes and the ocean. Aquaculture is consisting of two main types i. fresh water plants and animals ii. Marine water plants and animal. The main difference between fresh water and marine life is freshwater fish lives in stream, rivers and lacks that have salinity of less than 0.05 percent, however marine life refers to fish living in ocean and seas. The study reported that Marine biology is the scientific study of organisms that live in salt water. A marine biologist, by definition, is a person that studies, or works with a salt water organism or organisms. In other words Marine biology is the study of marine organisms, their behaviors and interactions with the environment. Marine biologists study biological oceanography and the associated fields of chemical, physical, and geological oceanography to understand marine organisms. The study reported that the total countries available in the world are 225, consist of (Developed countries = 49, developing countries = 150, observer state = 4, state without partial recognition = 8, unrecognized state = 14). Similarly, South Asia comprises the countries of Pakistan, Bangladesh, India, Bhutan, Maldives, Nepal and Sri Lanka.  In the light of above study, it is proposed that aquaculture and Marine Biology should be commercialized  for the development of health, basic need of daily life, create employment, generate income, stronger economy, reducing financial crises, global Poverty and hunger in the developing countries of the world particularly in south Asia.

Title: The Economic and Social potential of Seaweed Faming in Brazil


Alfredo Olivera Galvez is currently working as Professor at the Federal Rural University of Penambuco (UFRPE). He received his Doctoral degree on Biology of Aquatic organisms from the Sao Paulo State University (UNESP). He completed Post-doctoral stay on Biofloc Technology (BFT) in Waddell Mariculture Center at South Carolina - USA and Post-doctoral stay on Biotechnology of microalgae in Almeria University - Spain. He has authored several publications in various journals and books. His publications reflect his research interests in Sustainable aquaculture, seaweeds and microalgae production, bioremediation and Shrimp production. He is serving as a member or fellow in National Council for Scientific and Technological Development (CNPq – Brazil).


In Brazil, aquaculture activity has reached, in 2016, production of approximately 600 thousand tons (IBGE, 2016). Much of this production is in semi-intensive farming systems, with regular water changes and less biosecurity, However, in recent years the cultivation of marine shrimp has experienced viral outbreak problems such a IMNV (Infectious Myonecrosis Virus) and WSSV (White Spot Syndrome Virus) and consequently reduced productivity, for this reason it is necessary to use new production systems as the cultures in heterotrophic medium with zero exchange of water, where the development of the biofloc system (BFT) occurs through the manipulation of the carbon: Nitrogen ratio in the growing environment, stimulating the growth of microbial community formed by different microorganisms, these flocs constitute as alternative food to the cultivated animals, providing an increase in growth and participating in the regulation of water quality. However, some studies with bioflocs indicate a deficiency in polyunsaturated fatty acids as EPA and DHA. Thus, the planktonic and microbial communities found in Litopenaeus vannamei intensive cultivation systems play an important role in the recycling of nutrients, assimilating the nitrogen compounds and maintaining the water quality of these systems, thus promoting the incorporation of microalgae and rotifers to have a mixotrophic medium. The diatoms are outstanding because they have a high nutritional content and can contribute mainly with highly unsaturated fatty acids. In this context, the studies using Navicula sp. and Brachionus plicatilis in biofloc systems gave good results regarding the nutritional contribution of these live foods on the growth of Litopenaeus vannamei. Finally it is concluded that a mixotrophic culture with the inoculation of diatoms and rotifers in BFT systems has benefits for the development of post-larvae of L. vannamei, since it presented higher values in the performance variables for final mean weight, productivity, biomass gain, specific growth rate and increase of lipid contents in both the biofloc and shrimp body.

Title:  Sustainable intensive shrimp farming: Development of shrimp farm design and operation systems for possible control of shrimp diseases


Nyan Taw received his PhD in marine biology from the University of Tasmania, Australia under Colombo Plan Fellowship. On his return he rejoined as assistant lecture at Rangoon Arts and Science University. Later he joined Fisheries Corporation to head the R&D department. In 1983, he became project manager for ADB Inland Fisheries Development Project and technical counter-part for JICA projects in Myanmar. In 1988, he joined the FAO of the UN and served in aquaculture projects in Indonesia, Vietnam and the Philippines culminating the position of chief technical advisor. He had supervised 13 master theses for Zoology Department, Rangoon University and also published a book entitled Prawn Culture in Burma in 1984. He has published and presented over 80 papers and co-authored a chapter in the book by Yoram Avnimelech on Biofloc Technology: A Practical Guidebook (2012 & 2014).


The major diseases affecting the farmed shrimp industry were of bacterial origin in Asia from late 1980s. At present world-wide the appearance of various major viral diseases such as White Spot Syndrome Virus (WSSV), Yellow Head Virus (YHV), Infectious Myonecrosis Virus (IMNV), Acute Hepatopancreatic Necrosis Syndrome AHPNS and others – led to changes in design and operation systems of shrimp farms to prevent and control disease outbreaks. The most important development in early 2000 was L. vannamei SPF brood stock from Hawaii. Early shrimp farming design and operation were based on simple culture ponds with water intake and waste water discharge back into the environment known as ˜singlepond base management. In operation also to keep good pond environment the water was pumped in as required or known as ˜flow-through system. With intensive operation system the required DO was acquired through aerators and phytoplankton (DO production cycles) in pond water. This leads to unstainable in production due to unstable water environmental condition and environmental degeneration. Shrimp bacterial diseases such as Vibrio spp started to appear which a threat to shrimp farming industry was. This forced shrimp farmers to use reservoirs to treat the water before use and some most farmers constructed waste water system to treat waste water before discharging into environment. For stable environment and prevent diseases more energy was used with less exchange of pond water which was to some extent successful. From mid-1900s the WSSV appeared in Asia. These again prompt shrimp farmers to treat incoming water and waste water before discharging into environment. Recently, due to re-appearance of WSSV and outbreaks of AHPNS (EMS) farmers were using RAS systems in small shrimp farms or in raceways systems or modular systems in large shrimp farms. Recently the environment friendly biofloc technology, Aquaminicry, organic shrimp farming, etc, are being applied. However, the important factor for sustainable production was the farm biosecurity to control or prevent from shrimp disease entering hatchery or farm facilities. In any aquaculture business, sustainability of a system can improve profits. What investors, shrimp farmers and technicians need to be aware of is that, whatever waste is discharged into the environment, it will likely come back to you in the form of disease sooner or later.

She has published 38 papers in SCI journals and 13 book chapters and has been serving as an editorial board member of Ecological Indicators and Integrated Environmental Assessment and Management Journals. 


Marine bivalves are highly appreciated by humans, representing important economic value with an increasing demand. Aquaculture is a promising solution to overcome this demand. Aquaculture development has a stronger manifestation in some Asiatic, American, and European countries, like Portugal. In this study, six commercially important species (Cerastoderma edule (A), Crassostrea gigas (B), Mytilus galloprovincialis (C), Ruditapes decussatus (D), Scrobicularia plana (E) and Solen marginatus (F)) were sampled in areas of harvest and established aquaculture production in Portugal, the Mondego estuary and the Ria Formosa lagoon, in winter 2016 and summer 2017. These samples were used to: 1) determine the biochemical composition for total protein content, fatty acid (FA) and carbohydrate profiles 2) identify potential spatial and seasonal variations in the biochemical composition, and 3) assess feeding behaviour of the bivalve species in both seasons and study areas. All species presented higher total protein content, followed by diverse FA content, specially DHA and EPA, and glucose and glycogen as the main sugar and polysaccharide, respectively. Omnivory was confirmed in all bivalve species, with only S. marginatus presenting an exclusive herbivorous behaviour in summer. M. galloprovincialis and R. decussatus showed the highest nutritional value in the Mondego estuary, more noticeable in winter. In Ria Formosa, C. edule and R. decussatus presented the highest nutritional value, while C. gigas exhibited higher nutritive value in summer. These species are pointed out as the best choices for a healthy human diet and confirmed as a reliable choice for harvesting and production in aquacultures.

Title: Sea surface as a source for bioaerosols in the coastal zone of the Southern Baltic Sea


Anita U Lewandowska is an Associate Professor in the Marine Chemistry and Environment Protection Department, Faculty of Oceanography and Geography, University of Gdansk. Her primary research interests are in the field of atmospheric chemistry and oceanography with the special focus on processes of aerosol and gases exchange between the sea and the atmosphere under the influence of abiotic and biotic factors in the coastal regions of the sea. She is interested mainly in issues related to the Baltic Sea and Antarctica. She is a member of the Sea Research Committee of the Polish Academy of Sciences. She is author and co-author of dozens of scientific publications in the field of atmospheric chemistry and co-author of the book Aerosols and Gases in Earth’s Atmosphere - Global Changes and a Practical Guide for Students Aerosols and Gases.


Introduction: While cyanobacteria and algae living in sea water are well recognized, those that are the components of aerosols are rarely the focus of scientific research, especially in the Baltic Sea region. That’s why the aim of this study was to determine whether among the identified microalgae and cyanobacteria there were any capable of posing a potential threat to human health. Methodology & Theoretical Orientation: Bioaerosols were collected in 2015 on land and at sea on petri dished covered with f/2 culture medium and placed in six-step microbiological pollutant sampler (<1.1 μm->7 μm). In all samples the taxonomic composition and number of identified taxa were analysed. Findings: It was found that cyanobacteria and microalgae having been identified both in the atmosphere over the sea and over land during the entire study period are omnipresent microbiological air pollutants. Some of them had been transported from remote areas, such as Gloeothece sp. - a species not typical for the Southern Baltic Sea. Conclusion & Significance: The higher the primary production in sea water and the concentration of phytoplankton in it, the greater the diversity in terms of the microorganisms observed in the collected bioaerosol samples. Other important factors were: Water temperature, accessibility of light and the amount of available phosphorus and nitrogen in the surface water. In the atmosphere over land, microorganisms dominated in aerosol particles of smaller dimensions (<3.3 µm in diameter). Over the sea, there was a reverse situation. That resulted from the fact that smaller aerosols could be better distributed over long distances. Among the identified microorganisms were species which pose a threat to human health and life. Seeing as in the surrounding air, part of the everyday environment of the human habitat, those species were incorporated into small, respirable particles, it is necessary to conduct further research.

Title: Environmental sustainability of Nile tilapia net-cage culture in a neotropical region.


Veterinarian/ Master in Aquaculture (Sustainable production)/ Fish Nutrition/ Fish welfare and Quality control of fish in Sao Paulo State University , Brazil



The present study evaluated the environmental sustainability of Nile tilapia net-cage farms of different sizes by applying environmental sustainability indicators and exploring benchmarks combined with the indicators. One large-scale (LS), one medium-scale (MS), and two small-scale farms (SSI and SSII) placed in South-eastern Brazil were studied. Data from three batches were obtained from each farm during a production cycle, with durations ranging from 189 to 263 days, totalling twelve sample units for each variable. During fish production, samples of water, sediment, fish, feed, and greenhouse gases were collected and used to calculate the Environmental Sustainability Indicators (ESI). These indicators were grouped into five principles: the use of natural resources; efficiency in the use of resources; release of pollutants and unused by-products; pollutants accumulated on the bottom of the water body; conservation of genetic diversity and biodiversity. Each indicator was converted into a performance scale. Data of ESI obtained from each farm, and a literature review was used to develop a “standard” value, allowing the benchmarking of the environmental sustainability of the farms. The best environmentally sustainable index was obtained in the farm MS (87) followed by farm SSI (85) and the worst was farm SSII (73) farm LS achieved an index of 82. Farm SSI was positively influenced by the use of energy, nitrogen, phosphorus, and carbon, which was on average 17% lower than the other farms, and by the highest efficiency in the use of nitrogen and phosphorus (32.7% and 23.6%, respectively). Farm MS was positively influenced by the lowest phosphorus accumulation and organic matter (1 and 90 kg/t, respectively). Farm SSII was negatively influenced by the high levels of accumulated phosphorus and organic matter (10 and 723 kg/t, respectively). The results showed that environmental sustainability is independent of the farm size. Other factors, such as feed composition, management techniques, and water temperature, were more critical. The use of the benchmarking tool has shown to be a way to better use ESI to assess the sustainability of aquaculture in the absence of defined endpoints for each indicator. This tool provides a reference value for each environmental sustainability indicator, allowing improvements to reach desirable states.
