Understand the complexity of the output from an open pond system • Positive correlation between biomass productivity and EPA content • Negative correlation between biomass and FAME content • Both EPA and FAME productivity were positively correlated with biomass productivity Set the right objective • For e.g. If % lipid is a focus, you lose not just fuel productivity, but also the overall yield and value of your pond Make the right compromise Page 10 © Cellana 2013 Mid-scale ALDUO™ Optimization -Pond depth & Turbulence -Deeper ponds, higher productivity -Difference between depths bigger at early stage of the ponds -Higher PW speed (40%-60%), higher productivity for ponds at early stage -Further increase to 70% did not increase biomass productivity -PW speed had higher impact on shallower ponds Page 11 © Cellana 2013 Over 5 MT of Cellana’s ReNew Algae Used in Diverse Feed Trials; All Trials Successful To Date Algae Biomass Amount Feed trial Institution Location Testing animal Key results Feed formulation species type (kg) duration Algal replacements were acceptable 5-10% replacement of plant Bodø University Norway Atlantic salmon* C323/C88 defatted/whole 1,000+ at the maximum levels tested* and animal protein* 12wks 25-40% replacement of Algal replacements were acceptable both plant and animal Part of same at the maximum levels tested* Bodø University Norway Carp* C323/C88 defatted/whole trial as above protein* 12wks 25-40% replacement of Part of same Algal replacements were acceptable both plant and animal Prince of Songkla trial as above at the maximum levels tested* University Thailand whiteleg shrimp* C323/C88 defatted/whole protein* 12wks Thai Union Thailand shrimp C323 Defatted 880 On-going Work in progress Bodø University Norway fish C046 Defatted 850 On-going Work in progress Laying hen: increased redness in ~7% replacement of Cornell New York laying hen, pigs, broilers C323 Defatted 500 egg yolk soybean or soybean+ corn 6wks Weanling pigs: comparable growth ~7%replacement of Cornell New York laying hen, pigs, broilers C323 Whole 500 on algae supplement diet soybean or soybean+ corn 6wks Higher inclusion rate; comparable Work in progress Cornell New York laying hen, pigs, broilers C046 Defatted 800 growth 6wks Cornell New York laying hen, pigs, broilers KA19 Defatted 600 High n-3 eggs and meat.
