Dry Weight Calculations |
|
Dry weight is the weight of the product with all the water removed. Reed Mariculture measures dry weight in our microalgae products by placing 100 grams of concentrate into an 80' C drying over and cooking until nothing is left but powder. Then we measure the residual to determine the dry weight. In Nanno 3600 100 grams of concentrate will result in 18 grams of powder, hence it is an 18% dry weight product. The microalgae community has long known that cell counts are a very poor method of measuring algae when it is being used for feeding other organisms because the size and weight of the algae cells vary based on temperature, amount of light, and photo period. For example, TW ranges between 4 and 20 microns, depending on environmental conditions. If you were to feed 100,000 cells at 4 microns vs. 100,000 cells at 20 microns, the biomass difference would be roughly 125 X different (4x4x4=64, 20x20x20=8000, 8000/64=125) so your animals are getting either far too much, or far too little food. While it is known that cells counts are a poor measurement, that is the only measurement that has been available to those growing live algae because that biomass weight of live algae is so small that it cannot be accurately measured. However the introduction of microalgae concentrates has changed this and now feeding your target animals can be done accurately and consistently. |
