Editor's picks from recent stories in the news.

The Fish Whisperer
Adri Bout’s turbots live on land - in eight-story fish high-rises that he designed especially for them. And the turbots like it there – they like it a lot.
Adri Bout‘s Seafarm is one of the most unusual and most environmentally friendly aquaculture farms in Europe. Adri Bout can finally do things the way he believes they should be done –perfectly as possible. Read the story. [Siemens]

 

Shrimp farming research funding gets creative, competitive in face of budget cuts
Addison Lawrence and Tzachi Samocha are on a mission to lift an entire industry. Their target: U.S. shrimp.
Dr. Addison Lawrence, Texas A&M University AgriLife, has designed a system that takes the current method of growing shrimp in raceways and stacking them in climate-controlled spaces. The technology makes shrimp farming possible anywhere in the world. Among his studies, Samocha has been working in diet development. He's found it possible to replace two-thirds of the fish meal used to feed growing shrimp with algal and cottonseed products and get the same growth results, which can cut costs. Samocha said he is working with industry to do more partnerships, such as arrangements with feed manufacturers to continue to feed his shrimp and dissolved oxygen monitors to ensure they live.

Related story: Company plans to build shrimp farm in Coastal Bend
Researchers now have faster, organic ways to make them meatier.Using those methods, Lawrence has created a sustainable technique that makes farming the protein-rich crustacean possible anywhere in the world. Get ready: Shrimp is the new chicken, Lawrence said.  The process includes raceways, or long troughs filled with water and stacked atop one another, with recyclable water kept clean and in motion.

Improved catches in southern hemisphere boost fishmeal production and drive prices lower
Combined world production of fishmeal fell sharply last year caused by declining catches in producing countries in South America. By region, fishmeal output fell back 27% in South America whereas European production bounced upwards by 39% thanks to higher catches in Norway in particular Read Story

Prebiotics in aquaculture: a review
E. RINGØ1, R.E. OLSEN2, T.Ø. GIFSTAD3, R.A. DALMO1, H. AMLUND4, G.-I. HEMRE4, A.M. BAKKE5,6
DOI: 10.1111/j.1365-2095.2009.00731.x

 

Abstract: A prebiotic is a non-digestible food ingredient that beneficially affects the host by selectively stimulating the growth and/or the activity of one or a limited number of bacteria in the colon. Despite the potential benefits to health and performance as noted in various terrestrial animals, the use of prebiotics in the farming of fish and shellfish has been less investigated. The studies of prebiotics in fish and shellfish have investigated the following parameters: effect on growth, feed conversion, gut microbiota, cell damage/morphology, resistance against pathogenic bacteria and innate immune parameters such as alternative complement activity (ACH50), lysozyme activity, natural haemagglutination activity, respiratory burst, superoxide dismutase activity and phagocytic activity. This review discusses the results from these studies and the methods used. If the use of prebiotics leads to health responses becoming more clearly manifested in fish and shellfish, then prebiotics might have the potential to increase the efficiency and sustainability of aquaculture production. However, large gaps of knowledge exist. To fully conclude on the effects of adding prebiotics in fish diets, more research efforts are needed to provide the aquaculture industry, the scientific community, the regulatory bodies and the general public with the necessary information and tools.

Metabolism, interactions, requirements and functions of vitamin E in fish
K. HAMRE
DOI: 10.1111/j.1365-2095.2010.00806.x

 

Abstract: Vitamin E is a generic term for a group of lipid-soluble molecules, the tocopherols and tocotrienols, which have a function in the protection of organisms against lipid oxidation and which also may have other, more specific biological functions. In fish, as in other vertebrates, α-tocopherol (TOH) is preferentially retained in the body compared to the other tocopherols, probably because of the presence of a tocopherol transfer protein (TTP) in the liver which binds the tocopherols with different affinities and returns them to the circulation. Tocopherols that bind weakly to TTP are to a greater extent excreted in the bile. α-TOH interacts with other nutrients, and the requirement therefore varies with the dietary composition. High levels of polyunsaturated fatty acids, and low levels of vitamin C, selenium and astaxanthin increase the requirement. This is attributed to the dynamic nature of both lipid oxidation and the antioxidant defence, where oxidized vitamin E is recycled by other antioxidants. The interactions also determine the display of vitamin E deficiency signs, immune responses and effects on flesh quality. Within the mammalian nutrition research community, there is a controversy as to whether vitamin E is primarily an antioxidant or a specific modulator of cell signalling through regulation of enzyme activities and gene expression and some of the hypotheses are presented in this review.

Effects of different dietary lipid sources in the diet for Pangasius hypophthalmus (Sauvage, 1878) juvenile on growth performance, nutrient utilization, body indices and muscle and liver fatty acid composition
R. ASDARI, M. ALIYU-PAIKO, R. HASHIM, S. RAMACHANDRAN
DOI: 10.1111/j.1365-2095.2009.00705.x

 

Abstract: Four isonitrogenous (300 g kg−1 crude protein), isoenergetic (21 kJ g−1) experimental diets were formulated to contain fish oil (FO), soybean oil (SBO), crude palm oil (CPO) and linseed oil (LO), respectively, as lipid sources each at inclusion level of 120 g kg−1 and fed to triplicate groups of 15 juvenile iridescent shark, Pangasius hypophthalmus (Sauvage, 1878) (mean weight 10.00 ± 0.70 g) to apparent satiation twice daily for 12 weeks. The results showed that survival of fish was consistently over 95% for all treatments whereas growth performance in the SBO and CPO treatments was similar and significantly (P < 0.05) higher than for fish fed the LO diet. However, fish fed all vegetable oil-based diets performed better than those fed the FO diet. Muscle and liver fatty acid composition for all treatments generally reflected the composition in the diet and the ratio of n-3/n-6 was found to play an important role in P. hypophthalmus, suggesting that excessive amounts of n-3 fatty acids reduce the overall growth performance. Results of this study thus suggests that P. hypophthalmus fed diets containing vegetable oils (especially CPO and SBO) produce better growth than those fed FO diet without showing any signs of nutrient deficiency.
