The cost of acid, estimated to be $35.00 per ton of dry meal, is excessive 

 considering the relatively low value of the starfish as fertilizer. Acid treatment 

 further decreases the fertilizer value in two ways: by loss of nitrogen, pre- 

 sumably by leaching of a soluble protein hydrolysate; and by replacement of part 

 of the alkaline acting calcium carbonate by the neutral, relatively insoluble 

 calcium sulfate. 



Acid treatment of starfish involves danger to person and property in the hands 

 of inexperienced persons lacking special equipment and protective clothing.
