IAF article: Effect of dietary inclusion of seaweeds on intestinal proteolytic activity of juvenile sea bream. María Isabel Sáez, Tomás Martínez and Javier Alarcón Universidad de Almeria, Spain, describe the effect of dietary inclusion of seaweeds on intestinal proteolytic activity of juvenile sea bream. In recent years considerable attention has been paid on the use of seaweeds (SW) as a possible ingredient for aquafeeds. Red, green and brown SW can be taken from their natural habitat and brought to the shore by the action of winds and tides. Otherwise, biomass can be obtained from secondary and tertiary treatment of effluents.
Wastewater treatment utilising photosynthetic organisms is an interesting alternative to reduce the ecological impact of domestic, industrial or aquaculture effluents. Generally, high-quality algal biomass is yielded from algal cultivation, representing an excellent source of hydrocolloids, carotenoids, and bioactive substances, which allows different industrial applications.

IAF interview: Torben Svejgaard, chief executive officer, BioMar Group, Denmark. Born in 1955, Torben Svejgaard is chief executive officer of the BioMar Group, headquartered in Denmark.
At 57 years he is an economist with close to 30 years’ experience in B2B businesses with the first 25 years in the food ingredient area. From 1985-1991 he was marketing assistant and marketing manager at Aarhus Olie - speciality vegetable oil products and soy protein concentrates. Then from 1991-2008 he held different upper management positions within Danisco (now Dupont), a world leader in functional food ingredients plus biotech products for feed, biofuel and technical purposes. From 2004-2008 member of Executive Committee, that is the top management team of the company.
Will farming other species of fish follow the salmon example? In my view, there is no doubt that fish farming will become more and more professionalised over the coming years. You can see this happening for other species not just from a feeding point-of-view but also in farming. I don’t think so. Beneo.

Novel additives to reduce the economic impact of disease on shrimp production by Peter Coutteau PhD, Business Unit Manager Aquaculture, and Tim Goossens PhD, R&D Engineer Gut Support, Nutriad International NV, Belgium Penaeid shrimp production is under continuous threat from bacterial and particularly viral infections which have caused disastrous collapses of the industry in all major shrimp producing countries. Disease problems in shrimp production are complex and often still poorly understood. Regulations, consumer demands and sustainable management strategies restrict the number of drugs available to treat pathogens. Vaccines are likely to be ineffective in crustaceans, which lack a specific immune system similar to that of vertebrates. Therefore, shrimp producers must consider the seed stock quality, husbandry procedures and healthy nutrition as the major tools to control disease.

International Aquafeed Newsletter October 2012 edition. 5th Algae World Asia is devoted to analyzing the latest development in algae technology, advancements in research, commercialisation solutions and much more! For starters, at this conference in Singapore, you'll meet and learn from Assoc Prof. Lee Yuan Kun of Department of Microbiology, National University of Singapore (NUS) as he presents session on "Bottleneck in Outdoors Photosynthetic Productivity: Why is Algal Production Expensive, the Way Forward". You'll also hear Shilpa Ramani, Scientist and Global Project Leader, Novozymes South Asia Pvt Ltd deliver a paper entitled "Enzymatic Technology to Produce Fuel Ethanol, Fine Chemicals, and Protein from Seaweed". Next, given that the industry is marking milestones with the development and commercialisation of algae-derived products, particularly in the Asia Pacific region where the diverse market is growing immensely, we have lined-up these top experts and their sessions on High Value Added Ingredients from Algae: Aquaculture 2013.

The warmth of the sun overhead mirrored the warmth of the welcome we received this morning from officials in Keelung, Taiwan.
The day dawned sunny, despite warnings of a typhoon moving in on Taiwan, and our press conference to launch this leg of our tour with the Esperanza went ahead successfully. Sadly, the future for tuna may not be quite as sunny as the skies over Taiwan. Speaking from the heli-deck on the stern of the Espy, journalists heard my colleague Yenning tell of the decline in fisheries and, in particular, the sharp decline of the tuna, a species targeted for its economic value as well as its taste. If current trends continue, however, Greenpeace as well as local Taiwanese fishermen worry that the tuna will not exist in the future.
Greenpeace recently conducted polling of people in Taiwan and interviewed coastal fishermen to hear directly how Taiwanese people view the situation in the oceans, and released a report and video today summarising the results.

European Science Education Media: multimedia on health food environment biotechnology genetics safety and genomics research. No plankton means no life in the ocean Understanding where and when plankton occur at different depths in the ocean allows scientists to get a global understanding of the function and health of the ocean from small to global scales. Plankton also play an important role in the global carbon cycle. This cycle captures the Sun's energy and the atmosphere's CO2 at the surface of the ocean and releases it to other organisms and other areas of the ocean.

Fishing quota Fisheries Committee calls for end to overfishing and discards Support Coastal Fish! The effects of dissolved oxygen on fish growth in aquaculture. New issue of International Aquafeed online now! Why deep-sea dragonfish have such extraordinary jaws - life - 23 January 2012.
NICE fangs, shame about the bite. The oversize fangs of some dragonfish may help them to snap their weak jaws shut around prey, improving their odds of bagging a meal. The dragonfish family (Stomiidae) go after large prey, and so have jaws that open wide. Closing them quickly is not easy, says Christopher Kenaley of Harvard University, since drag increases exponentially with jaw length, and rises even more if bulky prey are sticking out the front.
What's more, dragonfish jaw muscles are very weak. Kenaley built a computer model of the jaws and found that shutting them around prey lying on its side took up to 1 second - more than enough time to allow it to get away. Kenaley says the results suggest the fangs may not just impale prey as previously thought but help keep it in the best orientation to reduce drag on the jaw when it shuts. When this article was first published, it incorrectly mentioned anglerfish instead of dragonfish. More From New Scientist More from the web Recommended by. Global Aquaculture News & Events.
