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.

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.

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.

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.

  • Fish and Omega-3: Questions and Answers for Health Professionals
    Fish and omega-3: Questions and answers for health professionals The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 milligrams (mg) of marine-sourced omega-3s (EPA, DHA) per day. The Heart Foundation also recommends that all Australians should aim for 1 gram of plant-sourced omega-3 (ALA) each day. The Heart Foundation based these recommendations on a scientific review of evidence. For more information, you can access the full text article in the journal Heart, Lung and Circulation, available at www.heartlungcirc.org/article/S1443-9506(15)00167-5/abstract Marine-sourced and plant-sourced omega-3s should be included as part of a heart-healthy diet that includes vegetables and legumes, fruit, wholegrain cereals, lean meats and their alternatives, fish, nuts and seeds, reduced fat milk, cheese and yoghurt, healthier fats and oils, and limits salt. Key messages Fish The Heart Foundation recommends all Australians should aim to include 2–3 serves of fish (including oily fish) per week as part of a heart-healthy diet. This provides around 250–500 mg of marine-sourced omega-3s (EPA, DHA) per day. Because the body cannot produce omega-3s they need to be sourced through diet. The scientific evidence supports fish as the best dietary source of omega-3s and found higher fish intake was consistently associated with lower rates of heart disease (heart failure and sudden cardiac death) and stroke. Fish with the highest levels of omega-3 include salmon, blue-eye trevalla, blue mackerel, herring, canned sardines, canned salmon and some varieties of canned tuna.

  • Prescription: Sustainable Seafood
    Why health professionals should care about sustainable fisheries PRESCRIPTION: SUSTAINABLE SEAFOOD Health benefits of seafood consumption A growing body of scientific literature demonstrates that consuming even modest amounts of fish helps protect against heart disease and stroke, and may have important benefits for pre- and post-natal cognitive development. The federal government1 and American Heart Association2 both note that eating two servings of fatty fish per week may reduce the risk of coronary heart disease in healthy people and the risk of mor- tality from cardiovascular disease in people who have already experienced a cardiac event. At present, Amer- icans fall short of these consumption levels, averaging only five ounces of fish per week. U.S. fish oil capsule sales have tripled in recent years. By contrast, terrestrial sources of omega-3s contain primarily the shorter chain alpha-linolenic acid (ALA), which is not as beneficial. Some food products are enriched with omega-3s— generally plant-derived ALA or fish-derived DHA/EPA.4 At least one company produces DHA directly from marine algae; their product is used to enrich many infant formulas and a few other products.5 However, commercial use of algal DHA in foods is not wide- spread to date. In short, consuming fish or fish oil (or products Salmon is popular for its high omega-3 content. enriched with fish oil) is currently the only way to add substantial quantities of key heart-healthy omega-3s Omega-3 fatty acids to the diets of most Americans. Cardiovascular benefits are greatest from consuming fish high in long-chain omega-3 fatty acids, namely docosahexaenoic acid (DHA) and eicosapentaenoic Wild fisheries acid (EPA).3 The highest levels of these omega-3s occur Sadly, even as the health benefits of eating fish are be- in small oily fish such as mackerel and herring, and coming increasingly clear, the ocean’s ability to provide larger predatory fish such as salmon and some tuna.

  • Nutritional Benefits of Seafood
    SOUTHERN REGIONAL SRAC Publication No. 7300 AQUACULTURE CENTER October 2012 VI PR Nutritional Benefits of Seafood Elizabeth Reames1 Seafood is a healthful choice for people of all ages— growing children, pregnant women, active adults, and the elderly. Seafood is an excellent source of lean, high quality, easily digested protein. A 3.5-ounce serving of seafood provides almost half of an adult’s daily protein needs for only 100 to 200 calories. Seafood is low in satu- rated fat and sodium and is a rich source of many essen- tial vitamins and minerals. Seafood also is one of the few foods that contain long-chain omega-3 fatty acids, which have many beneficial health effects and are essential for the development of the nervous system and retina. Seafood includes fish such as catfish, salmon, tuna, trout and tilapia, and shellfish such as shrimp, crab, clams and oysters. Most of the seafood purchased in the United States comes from marine waters and from aqua- culture (farm-raised fish). Boiled crawfish platter. (photo provided by W.
