Title: Chemical treatment to soften the bones of small fish for edible purposes

Abstract: Subject invention provides a simple and inexpensive chemical process for softening the dangerous spines and the small chest bones which radiate from the backbone of small fish, particularly the catfish. This is accomplished by soaking the pre-gutted and prescaled fish in an aqueous solution of Hydrochloric Acid at temperatures below about 100.degree. Fahrenheit until the spines and chest bones become acceptably soft. The acid treatment renders the chest bones sufficiently soft and without adversely affecting the quality and palatability of the meat.
