Biography:

Fatma Al-Abri received her BSc degree in Marine Science and Fisheries from Sultan Qaboos University in May 2004, Oman. She has worked as an Assistant Researcher at the Center of Excellence in Marine Biotechnology - Sultan Qaboos University since December 2011. She is highly involved in research interest with aquaculture and aquaponics. She had served as Specialist Fish Wealth Development at Ministry of Agriculture & Fisheries Before joining SQU, from 2009 to 2011. She has attended several national and international conference, symposiums, trainings and organized national workshops and conference.

Abstract:

Aquaponics is the combination of fish production (aquaculture) with the soil-less production of plants (hydroponics). It operates within a closed-loop system and utilizes minimal resources. Fish feed provides most of the nutrients required for healthy plant growth. These nutrients, excreted directly by the fish, or generated by the microbial breakdown of organic wastes, are absorbed by growing plants. Nutrient removal by the plants in turn treats the water by removing nitrogenous compounds, such as dissolved ammonia, which are harmful to fish. Water is then re-oxygenated and returned to the fish tanks. Fresh, potable water is added to the system, as necessary to replace evaporative loss. In 2010, a report was published by a group of scientists from Sultan Qaboos University and the Ministry of Agriculture and Fisheries Wealth for the combined production of tomatoes and red hybrid tilapia. This research had support from the Agricultural and Fisheries Development Fund (MoAFW). Various types of salad crops have been grow with Nile tilipa in aquaponics system in climate-controlled greenhouse. This paper describes the testing of an aquaponics system using floating rafts. In this system the plants are grown in small coir pots and receive their necessary minerals from the fish tank via the water which circulates around their exposed roots beneath floating Styrofoam rafts. This paper reports the productivity of fish and plant crops, measures of the release and uptake of minerals and the results of microbial tests on produce.

Abstract:

The study was conducted to know the quality of Fresh fish and iced fish by using Indian Mackerel (Rastrelliger Kanagurta) and Pink perch (Nemipterus japonicus). The Fatty and Lean variety of fishes were procured from the fish landing centers off Mangaluru coast to the college laboratory. For the first day, from both the variety of fishes half quantity were taken for preservation under iced condition in insulated box and half of the quantity was  used for preparing a products like, Smoking, Freezing and Canning. At the end of 6 days and 8 days of icing the  fatty variety fish (Mackerel) and lean variety fish (Pink Perch) were started degrading in their quality while analyzing the Physical, chemical and sensory evaluation respectively. After 6 and 8 days of preservation of fish in insulated box under iced condition was used for the preparation of final quality of the product. The iced and fresh fish of first day prepared product was compared together to obtain the conclusion. The iced fishes which were used for smoked product preparation was found suitable up to 20 and 30 days in mackerel and pink perch respectively but the fresh fish was found suitable up to 25 and 35 days respectively. In case of freezing, 4 and 7 months in case of freezing of mackerel and Pink perch of iced fish and 6 and 8 months in case of freezing of mackerel and Pink perch of fresh fish. However, the iced fish used for canning was found suitable up to 8 and 10 months respectively and 9 and 12 months in case mackerel and pink perch respectively of canned products. It was concluded that, fresh fish will have little more shelf life than that of iced fishes and lean variety fishes having more shelf life both in case of fresh as well as in iced condition but the iced fishes can also be used for preparing various products in the later days for effective qualities.

Nirmal T., has completed his degree in fisheries science and specialised in Fisheries Resource Management. He has been contributing his hardship and dedication in fisheries sector for 10 years in taxonomy and behavioural studies of crustacean especially hermit crabs.

 

Abstract:

Shell selection and utilization pattern of tropical hermit crab, Diogenes alias McLaughlin & Holothuis, 2001 was studied based on specimens collected from Arabian sea from Mumbai, northwest coast of India. In the natural habitat, the most common occupied molluscan shells as shelter by the species, were of Tibia curta followed by Indothais lacera. Similarly, male hermit crabs occupied more species of gastropod shells followed by female and ovigerous. The influence of species of molluscan shell, size of shell and sex of hermit in shell selection was studied in the laboratory condition where the animals were found to prefer Indothais lacera over other molluscan shells. The smaller crabs occupied more number of shells species than larger sized individuals, probably due to availably of more shells to fit in in their body as compared to larger animals. A high correlation was found between the internal volume of shell and weight of hermit crab occupying it. The result obtained from the study revealed that shell availability and architecture of shell influence shell occupation and selection process in hermit crabs.

Abstract:

Estradiol signalling is stimulated or inhibited depending upon the interaction mechanism of estrogen receptors, ERα and ERβ. Soy-phytoestrogens, especially genistein, is known to bind these receptors and affect vitellogenin (vtg) synthesis. Fifty-six days of feeding trial was conducted to evaluate the effect of genistein on ERα, ERβ and vtg gene expression in male and female brooders of Cyprinus carpio. Five groups of fishes were fed with 0 (C), 1 (G-1), 3 (G-3), 6 (G-6) and 9 (G-9) mg% genistein contained feed during the trial. mRNA concentrations in liver tissue were determined by relative analysis using real-time PCR. The study observed a significant vtg mRNA level reduction from G-6 in female and a significant induction in male fishes after G-6. Expression of ERα gene was showed an increasing trend up to G-6 in while ERβ gene expression was reduced with increasing dose of genistein in female fishes. Higher ERα mRNA level was observed in G-3 and G-6 in male fishes, while ERβ mRNA level was comparatively lower in male and showed no significant difference between the treatment groups. The study revealed that both ERα and ERβ are sensitive to dietary genistein in female brood fishes than male. Genistein at 6mg%, so as soybean meal at 27% inclusion (considering genistein content of defatted soybean meal is 22.50±1.09 mg/100g) disrupts the estradiol cascade pathway by reducing the expression of ERβ gene and vitellogenin synthesis in a female brooder of C. carpio. Genistein induces vitellogenin synthesis at 6mg% by inducing ERα gene expression in the liver of male brooder. Hence the investigation concludes that though the practice of soybean meal in aquafeed is inevitable; however, its inclusion in a brood-stock diet needs serious attention.

Abstract:

The economic analysis and operational efficiency of the marine fishers and their attitude towards development schemes serve as significant information which is vital for implementing new technologies and policies. With this view in focus, the present study was taken up to analyse the economic aspects of marine fishing including terminal division and supportive facilities in Gujarat during the period 2015-16. A total of 120 fishers and 40 input suppliers were selected for the study from four major harbours/landing centers of the four districts in the state which made the total sample size of 160. Craft and gear were a major added cost in fishing and estimated total cost and profit of boat builder for one wooden boat was ₹ 13.9 lakh and ₹ 4.75 lakh whereas for fiber boat it was ₹ 1.23 lakh and ₹ 40,767.4 respectively. The economics for the sample gear manufacturer displayed total cost and profit of ₹ 300059 per day/cycle and ₹ 3306.89 per day/cycle. The study depicted that the majority of fishers were living in a joint family with a family size of >9 followed by the family size of 4-6 persons. The majority of fishers had the education up to higher secondary level while the average age of fishers was 37.76 years which also indicated that the fishing business has adhered even younger population. The total cost of fishing was estimated about ₹ 2.25 lakh per trip while the average revenue generated by fisher was depicted ₹ 2.78 lakh/trip with net revenue of ₹ 53,223 per trip denotes the viability of the business. Due to high dependency on seasonal weather, natural resources and stock, over exploitation and numerous other problems, income from fishing remain flexible subject. Out of 120 fishers, only 63.33 percent and 54.17 percent of fishers were technically and economically efficient. Since majority of the fishers irrespective of fishing operations are operating at low-efficiency levels in Gujarat, there is an urgent need of fleet-size reduction, promotion of target fishing, technology transfer, better training, banking facility and subsidies to improve and support their operational skills to attain full efficiency level for enhancing their profitability in fishing.

Abstract:

In Ecuador, the bivalves of genus Spondylus, mainly S. crassisquama and S. leucacanthus, are very seriously threatened by overfishing. This research has implemented experimental protocols for spawning induction and early larval development of S. crassisquama under controlled conditions. This laboratory study has been led at the experimental unit from the Academic practices, Production and Biological Research Centre (CIBPA) at the Santa Elena Peninsula State University (UPSE), located in Mar Bravo beach, Santa Elena Province, Ecuador. A total of 4 individuals of S. crassisquama broodstock (weight, 729,8 ± 113,4 g; length, 138,9 ± 11,9 mm; height, 105,6 ± 5,8 mm) were collected from Ayangue beach and acclimated in 300 L plastic tanks with treated seawater. Briefly, the experimental protocol for spawning induction was based on heat shock (20°C for 1 h and 30°C for 1 h) on broodstock at least three consecutive times by two days. After spawning, collected sexual material was released for external fertilization process. As main results, first and second cellular division were reported at 1,6 h post-fertilization; later cellular divisions, including trochophore stage, appeared in the next 9 h post-fertilization, while type D (veliger) stage was described at 22 h post-fertilization. Umboned larvae were reported at day 10 post-fertilization. Early larval population displayed less of 2% survival at day 10 post-fertilization. This work describes for the first time the spawning induction and early larval development of S. crassisquama in captivity. These results will encourage the larval culture of S. crassisquama for future restocking processes of natural populations.

Keynote: The efficacy of various filter media in removing copper from treated seawater

Time : 1:30PM

Biography:

Keshia Govender, 33 years old, Btech Biotechnology, 8 years in water quality (chemistry and microbiology).

Registered with south African council for natural scientist's as a candidate scientist.Research project done to remove copper medication from quarantine exhibits using different filter media such as banana peels and activated carbon and zeolite

Abstract:

Antiparasitic copper treatment is an integral part of routine marine aquaria quarantine, and, at times is even used to treat fish on exhibits. Free copper will react with calcareous materials (e.g. coral, rock or limestone), to form insoluble copper carbonate. This will leach out into fresh, untreated saltwater once a bath treatment is completed. As copper is extremely toxic to invertebrates, any residual copper can cause unexpected mortality.  

This project investigated and compared the efficacy of various filter systems in removing residual copper in saltwater.  The four filter media examined were activated carbon, zeolite, poly-filters and powdered banana peels.

The experiment was undertaken using five glass tanks each having seawater, airlines, copper lines and canister filters. The first tank was used as a control. There were three phases to the experiment. The copper tests, temperature and pH were taken through all three phases.

My results showered that zeolite together with powdered banana were the most successful in absorbing the most amount of free copper. The pH within this time frame was 7.8-8 and temperatures were relatively stable. After two months the zeolite became deactivated and activated carbon achieved good absorption of free copper. Powdered banana showed immense absorption however the pH levels would drop on certain days. The Poly-filter showed very slow absorption during the entire experiment through all three phases.

In conclusion activated carbon was the best filter media although taking a long period of time to absorb the free copper. Some results were zero or extremely low levels of free copper detected. Powdered banana was the second filter media that absorbed the most amount of free copper however the pH readings took time to stabilise. Environmentally these filters can be used in waste water treatment plants to remove heavy metals such as copper either by having canister were the media is added in or in biofilters were the various media can be added.

Biography:

Mr. Luqman Hakim, studied Chemistry at the University of Malakand, KPK, Pakistan. Luqman joined the research group of Dr. Muhammad Usman at the Agricultural Research System Pakistan. Mr. Luqman experience on research and development of integrated aquaculture production, industries and sustainable way.

Mr. Luqman published several research papers, always participated in the international conferences as a keynote speech, of the conferences around the world.

 

Abstract:

The title of presentation consists of aquaculture and fisheries, health, life, global poverty and hunger in the world. The study reported that aquaculture and fisheries industries on a sustainable way create income of growers, generate employment and subsequently reduce global poverty and hunger in the world.  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 divided in to 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. Fishery is related with fish and shellfish. It is the animal living in water, however fishery is a place where fish are reared or caught on commercial basis. The study further showed that 85% fish productions are in sea marine and only 5% are in water growers commercially. Similarly the study reported that horticulture is the art or practice of garden cultivation and management. In the light of the above study, the industry of aquaculture and fisheries should be commercialized for the development of health, basic need and daily use of life, absorbing millions of technical and non-technical people, generate income, create employment, stronger economy, reduce financial crises, global poverty and hunger in the world.

Abstract:

The title of presentation consists of aquaculture, fishery, horticulture, health, life, sustainability, global poverty and hunger were studied to find out the role of aquaculture, fisheries and horticulture on the reduction of global poverty and hunger in the developing countries of the world like South Asia particularly in Pakistan. The study reported that aquaculture and fisheries industries on a sustainable way create income of growers, generate employment and subsequently reduce global poverty and hunger in the world.  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 divided in to 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. Fishery is related with fish and shellfish. It is the animal living in water, however fishery is a place where fish are reared or caught on commercial basis. The study further showed that 85% fish productions are in sea marine and only 5% are in water growers commercially. Similarly the study reported that horticulture is the art or practice of garden cultivation and management. The total number of countries are available in the world are 224, consist of 49, developed countries 49, 149 developing countries, 4 observers states, 8 state with partial recognition and 14 unrecognized states but the South Asia comprises the countries of Pakistan, Bangladesh, India, Bhutan, Maldives, Nepal and Sri-Lanka South Aisa is about one fifth of the world’s population, which is considered as the most densely populated region in the world. In the light of the above study, the industry of aquaculture, fisheries and horticulture should be commercialized for the development of health, basic need and daily use of life, absorbing millions of technical and non-technical people, like engineers, doctors, agriculturist etc, generate income, create employment, increase the job, stronger economy, reduce financial crises, global poverty and hunger in the developing countries of the world like South Asia particularly in Pakistan.
