Waste management for smoking salmon by- products to extract omega-3 fish oil Tarek Fouda Tanta University, Egypt
he main objective of this research was to investigate the possibility of producing fish oil from smoking salmon waste by using Tcold pressing and wet rendering methods. The amount and the characteristics of extracted oil were tested. The samples were used about 33.810 kg., smoked fish caused about 9.610 kg. As a Salmon waste (skin, viscera, backbone frames and cuts off) it's recorded about 20% of the total mass from salmon slices. The results showed the smoking salmon waste have more than18% of oily fish per one kg of salmon waste. The oil weight from Salmon by-products was increased with pressing time increase as well as oil productivity increased. The oil extraction yield increased and characterization of quality. The optimum conditions at pressing time were 180 min., oil weight was 93 g. oil/500 g. Salmon by-products, oil productivity was 18.00% and extraction efficiency was 98.46 % at constant pressure. The oil weight from Salmon by-products was increased with heating time increase as well as oil productivity increased. The oil extraction yield increased with the wet rendering processes at the heating time of 60 min. have oil weight about 90 g. oil/500 g. Salmon by-products, oil productivity about 18.00% and extraction efficiency was 95.23% The oil extraction yield increased with the wet rendering processes and characterization of the oil increases with cold pressing processes.

Image pearl culture: A new aquaculture approach in bangladesh Mohosena Begum Tanu, Arun Chandra Barman and Yahia Mahmud Bangladesh Fisheries Research Institute, Bangladesh
n experiment was carried out for the development of freshwater image pearl culture technology has been conducted at the Afreshwater station, Bangladesh Fisheries Research Institute, Mymensingh for a period of eight months from March to October 2017. A total of 1200 mussels (Lamellidens marginalis) were operated with the paraffin made image. The single image was inoculated per mussel. The operated mussels were stocked in the pond and cultured through the net-bag hanging method in 1-1.5m water level of the pond @80 mussels/decimal and 30 fishes/decimal (Catla catla 6, Labeo rohita 10, Cirrhinus cirrhosus 10, Labeo calbasu 4). Organic and inorganic fertilizer was given fortnightly to the pond @ 5 kg cow-dung, 0.125 kg T.S.P. and 0.1 kg urea per decimal. During the experimental period temperature (oC), Dissolved oxygen (mg/l), Alkalinity (mg/l), pH, NH4--N (mg/l), Ca2+ (mg/l) and Phytoplankton (x103cells/L) were ranged from 26.57±0.91, 5.90±0.06, 135±5.7, 7.77±0.10, 0.05±0.02, 25±3.1 and 50.25±6.85 respectively. Survival of mussel and growth of pearl were monitored once in a month. After 8 months culture, the survival rate of operated mussels was found 61% while image pearl production rate was 46% and the layer of nacre on the paraffin made images ranged between 0.5-0.9 mm.

Effect of nano-se supplementation on growth performance, hematology and carcass composition of Cyprinus carpio fingerlings fed sunflower meal based diet Muhammad Mudassar Shahzad, Syed Makhdoom Hussain, Anam Khalid and Fatima Khalid Government College University, Pakistan
he present study (70-days) was conducted to determine the growth performance, hematology and carcass composition of Cyprinus Tcarpio fingerlings fed sunflower meal based diet supplemented with Se nanoparticles. Sunflower meal based diet was used as a test diet and supplemented with nano-Se at different levels (0, 1, 2, 3, 4 and 5 mg Kg-1). Three replicates having 15 fingerlings in each tank were used for every treatment. Fingerlings were fed twice a day with nano-Se supplemented sunflower meal based diet at the rate of 5% of live wet body weight. The higher weight gain (16g), weight gain % (211%) and SGR (1.3) were observed when fingerlings were fed at 2 mg Kg-1 level based diet. Similarly, maximum hematological indices (RBCs, WBCs and Hb) and carcass composition (Crude protein, Crude fat and Gross energy) were also found in fish fed at 2 mgKg-1 of nano-Se supplemented sunflower meal based diet as compared to fish fed control and other test diets. The present work revealed that sunflower meal based diet supplemented with nano-Se improves overall fish performance and reduces the need for extra mineral and nutrients supplementation in fish feed, which decreases the feed cost with the better aquatic environment. The results of the present study suggest that 2 mg Kg 1 supplementation of nano-Se in sunflower meal based diet is the most optimum level for higher performance of C. Carpio fingerlings.

Utilization of knife fish (chitala ornata) in the development of value added products: An input for sustainable food production Maureen G Tamayo1 and Rosalina V Bunal2 1Laguna State Polytechnic University, Philippines 2College of Fisheries, Philippines
he clown knifefish Chitala ornata, a very popular knife fish. This is partly because of its common availability and being relatively Tinexpensive. But it’s also a favorite because it is extremely attractive. They usually have a pattern of large spots, but this can be quite variable and it seems that no two clown knifefish are exactly alike. They come from South America and South East Asia specifically from Thailand, Borneo, Malaysia, India and Sumatra and usually found in lakes swamps and river backwaters. They prefer still waters and can survive with low oxygen. Knife fish was accidentally introduced in Laguna de Bay, the largest lake in the Philippines during the super typhoon Ondoy in 2009 which caused flash floods in many parts of the country. As early as 2011, reports from fisherfolk surfaced regarding knife fish being a pest as it eats tilapia and milkfish fry which are the two main commodities caught from the lake. The proliferation of knife fish has affected the aquaculture and capture fisheries of the lake causing the catch and harvest of the fisherfolk to decline dramatically. The bulk of the fisher folks’ catch comprises now of knife fish which is not acceptable to them because it does not suffice to their previous income when most of their catch is bangus and tilapia. This is because knife fish only sells for 10-20/kg while bangus or tilapia is usually around P100.00/kg in local markets (BFAR IV-A). The fish is aggressive, highly carnivorous in nature and naturally breeds in ponds and open waters. In the wild, a knife fish can grow up to 100 cm in length and 5 kg in weight. According to BFAR-National Inland Fisheries Technology Center (BFAR-NIFTC), the fish consumes/requires seven kilograms of different type of fishes to grow to a kilogram. It is also rapidly produced with a fecundity of 20,000 eggs/kg of fish. Knife fish eggs are found attached on stakes and poles of fish cages and pens where they grow and feed on the tilapia and bangus fry and fingerlings. The fish is now considered as an invasive species and a threat to the biodiversity of the lake, particularly to the indigenous species including silver therapy or ayungin, goby or Biya and freshwater shrimp or hipon. One of the strategies of BFAR IV-A in the containment of knife fish is to explore its economic utilization. Under this is the use of knife fish as a raw material in postharvest. The knife fish is now used as a raw material in making nuggets, kikiam and siomai. In this research, the researchers utilized knife fish in making the fish ball, fish kropeck and fish patties. The Laguna State Polytechnic University (LSPU) Research and Development Agenda Formulation Workshop held last September 13, 2013, at LSPU Siniloan Laguna, wherein the framework of research priorities, as well as the LSPU Research and Development Mission and Vision Statements, were approved to the Board of Regents. In this forum, the research priorities were set and these junctures that the Vice-President for Research and Development identified Pangasius and Knife fish will be given priority in research activities for LSPU, Los Banos Campus. The University invested time and effort to make and adopt Pangasius and Knife fish as the main commodity for Research of LSPU, Los Banos Campus and is one of the State Universities and Colleges in the Cavite-Laguna-Rizal-Quezon (CALABARZON) offering fisheries courses in this part of region, the researchers in order to contribute to the collective effort of the faculty and personnel of the University, decided to focus on the Utilization of Knife Fish (Chitala ornata) in the development of Value Added Products: An Input for Sustainable Food Production.

Effects of dietary Spirulina powder on growth performance, body composition, hematological, biochemical and immunological parameters of Oscar fish, Astronotus ocellatus Negar Ghotbeddin Islamic Azad University, Iran
n this study, the changes in survival, growth, body composition, hematological, biochemical and immunological parameters of IOscar fish (Astronotus ocellatus) have been investigated with dietary Spirulina powder supplementation. Total of 300 fish with an initial weight of 8.37±0.36 was distributed to three treatments and one control (0%). The fish were fed 8 weeks with diets containing different concentrations of S. powder: (control (0%), 2.5%, 5% and 10%). Then sampling was done and different parameters were measured by standard methods. Growth performance such as weight gain (%), SGR and FCR significantly improved in fish fed with S. powder (P< 0.5). Crude protein significantly increased in the S. powder supplemented groups (P< 0.5). However, crude lipid decreased with the increasing of dietary S. powder levels. Total protein increased in fish fed 10% S. powder. Triglycerides and Cholesterol decreased with the increasing of dietary S. powder levels. Immunological parameters including C3 and C4 increased significantly with the increasing of dietary S. powder levels and lysozyme was improved in 10% S. powder. Results of this study indicated that S. powder had positive effects on Oscar fish and the best values were observed at 10 % S. powder.

Utilization of sambung nyawa-leaf (gynura procumbens) extract for the endurance of grouper (epinephelus fuscoguttatus) against vibrio alginolyticus attack Etika Oktaviani Lampung University, Indonesia
rouper (Epinephellus fuscoguttatus) is one of the superior export commodities with high economic value. The main obstacle in Gthe cultivation of grouper is the attack of bacterial disease. Vibriosis is one of the bacterial diseases that often attacks grouper farming and is the main cause of production problems because it can cause death more than 70% in a season so that the impact on the decrease of production and income. The Bacterial disease control has been using various types of synthetic antibiotics that have the potential to cause bacterial resistance in the prevention of disease and can be bad for humans. Phytopharmaca is one alternative that can be used to control grouper’s vibriosis. One type of plant that has the potential as a phytopharmaca is the sambung nyawa plant (Gynura procumbens) that could potentially be antimicrobial because it has the content of flavonoids and essential oils. Sambung nyawa is very easy to find in Lampung and also easy to plant. The purpose of this study is to study the effectiveness of leaf extract of sambung nyawa to prevent the attack of Vibrio alginolyticus on the grouper. This study used Completely Randomized Design with 4 treatments and 3 replications. The tested treatment was the addition of sambung nyawa leaf extract 0, 350, 700 and 1400 ppm in feed. In vitro tests show that a dose of 700 ppm can prevent the growth of V. alginolyticus. In vivo test proves that sambung nyawa leaf extract can increase the resilience of grouper.

Small scale fishreies maginalization: The future extinction Olanrewaju Badmus Aqua Research Center, Nigeria
rtisanal and Small-Scale Fisheries (SSFs) play a crucial role as a source of livelihoods, food security and income for millions of Apeople around the world in both developed and developing countries. They contribute about half of the global catch; supplying food for local, national and global markets. They are responsible for about ninety percent of fishing employment. They provide income, contribute to food security and nutrition, alleviate poverty and often support a way of life strongly anchored in local culture and community. Small-scale fisheries can make significant contributions to national economies through the generation of foreign exchange derived from international trade. International trade in fish and fishery products has grown rapidly over the last twenty years. Export values have risen from US$ 15 billion in 1980 to US$ 56 billion in 2001. In the same period developing countries' share of total exports has risen from 40 percent to 50percent, with net receipts (i.e. deducting their imports from the total value of their exports) from fish trade by developing countries increasing from less than US$ 4 billion to almost US$ 18 billion. Small-scale fisheries are playing an increasingly important role in the fish exports of many developing countries. In spite of the important role that SSFs play in national and local economies the sector—as compared against other sectors of the world food economy—is poorly planned and regulated, inadequately funded and marginalized and often neglected by all levels of government. SSFs around the globe are frequently overfished and overexploited as a result of not only weak governance, but, to name just a few issues, of poor management, perverse subsidies, corruption, unrestricted access and destructive fishing practices.

Genotoxic studies by induction of nuclear lesions and micronucleus assay in fish injected with phthalates Ghazala Jabeen Lahore College for Women University, Pakistan
enotoxic studies were carried out by induction of nuclear lesions and micronuclei in peripheral erythrocytes of C. idella. Fish Gwas exposed to Dimethyl Phthalate (DMP) (1.5 µgL-1), Di -n -octyl Phthalate (4 µgL-1) and mixture of both Phthalates 10 µgL-1 for 3, 6 and 15 days, respectively. Comparison of total protein content in all the treatment groups showed statistically significantly highest fluctuations in the protein contents. Hematological analysis of C.idella revealed the significant decrease in total RBCs count, hemoglobin concentration, hematocrit and platelet count. 15 days exposed group showed the lowest values of all hematological parameters e.g. RBCs count, Hct, Hgb, PLT count as compared to other treated groups. The frequency of Micronuclei and other Nuclear Abnormalities e.g. Notched, blebbed, Deshaped, Eight shaped, Binucleated, Lobed, Vacuolated, Multinuclei were analyzed in peripheral erythrocytes of C.idella. Prevalence percentages of MN and NL were highest in DNOP exposed group with following order: eight shaped nuclei > MN > notched> Deshaped> lobed nuclei while DMP exposed group revealed highest were as follows: Binucleated>blebbed>multinucleated.
