No it's not.
IMO, ALL enrichments, powder or emulsions need to be blended in a blender for a minimum of two minutes to "particularize" to smaller more acceptable size for nauplii consumption.
Some use the stick in blenders but I prefer to use a conventional blender on high as it appears to get smaller size particles, at least for my own appliances it does.
I also pour the resulting fluid through a fine mesh just to filter out any too large particles that won't get consumed and only contribute to contamination.
