  9. Fish Meals

  10. Soybean Meal Prices February-May 2012 $/ton Month Pricing Information from CME Group

  11. Exciting Advances in Aquaculture Nutrition • Traditional Soybean Breeding has yielded soy concentrate “on the farm”

  12. Anti-nutrients in plant derived ingredients Soybean Meal; Glycinine, ug/kg Beta Con Glycinine, ug/kg Lectins, mg/kg Dry solids, g/kg Stachyose, g/kg Raffinose, g/kg Oligosaccharides, g/kg Trypsin Inhibitor Activity, mg/g Saponin, Type B Ba, g/kg Saponin, Type Bb’ (type I), g/kg Saponin, Type Bb (type I), g/kg Saponin, Type B Bc (type II, III), g/kg Saponin, Type B Bc’ (type II, III), g/kg Type B Saponins, g/kg Type DDMP Saponins, g/kg Total Type B and DDMP Saponins, g/kg Phytate Information courtesy of Dr. Rick Barrows, ARS USDA

  13. Soybean Meal Processing and its impacts on Rainbow Trout Digestion and Assimilation Raw soybeans Toasting Hexane Extraction Soybean meal Soy oil 46-48% protein Human cons. Soy Protein Concentrate Esterfication ~60-70% protein Bio-diesel Soy Protein Isolate ~80% protein Information courtesy of Dr. Rick Barrows, ARS USDA

  14. Traditional Breeding of Soybean Improved Genetic Lines of Soybeans; Soybeans; Removed many of the negative traits of soybean meal All Non-GMO Information courtesy of Dr. Rick Barrows, ARS USDA

  15. First Feeding Fry Screening Fish meal A ULO 3010 A SPC B K419 C 204 D CC D WF D Grams per fish A B C Information courtesy of Dr. Rick Barrows, ARS USDA

  16. Improved Genetic Lines; Full Fat Soybeans Apparent Digestibility Coefficients Information courtesy of Dr. Rick Barrows, ARS USDA

  17. Improved Genetic Lines; Full Fat Soybeans Apparent Digestibility Coefficients 27% 19.5% 9% Information courtesy of Dr. Rick Barrows, ARS USDA

  18. Exciting Advances in Aquaculture Nutrition • Soybean Breeding has yielded soy concentrate “on the farm” • Algae meals-Product of huge investment in biofuels

  19. Exciting Advances in Aquaculture Nutrition • Soybean Breeding has yielded soy concentrate “on the farm” • Algae meals-Product of huge investment in biofuels • Camelina -dry land crop that yields oil and meal

  20. Certification Programs • Currently, a proliferation of schemes and eco-labels

  21. Certification Programs-Why? • Bad press on culture practices, especially indiscriminate use of antibiotics, antifungal agents (malachite), etc. • To assure wholesale buyers in United States that their product is quality, have had to adopt one of these programs • Not aware of many U.S. producers adopting certification programs

  22. Whole Foods • Potential market for U.S. produced fish and shrimp • Dietary guidelines prohibit the use terrestrial animal protein due to concerns about transmission of BSE prion • Once vegetable protein max has been hit, the remaining protein comes from fish meal

  23. Whole Foods • Typical 40% protein trout diet contains ~20-25% fish meal • Whole foods =>30% • Actually moving away from sustainability although they do have a fish in:fish out ratio that they have as their goal…….

  24. So What? Implications for LSRCP Hatcheries Price Volatility-reduce dependence on fish meal and other volatile ingredients Suggest working with hatcheries to evaluate diets incorporating soy replacements

  25. So What? Implications for LSRCP Hatcheries II Algae-additional work needs to be done to determine how to cost effectively use it Camelina-work ongoing. If results are promising, expect field trials in 1-2 years

  26. THANKS FOR YOUR ATTENTION!Questions? Rangen Inc. is a manufacturer of quality Aquaculture Feeds Located in Buhl, Idaho Started making fish feed in the early 1950’s U.S. owned
