Huge fishing requires a good treatment of the product in order to reduce high level loss of 30%-40% when arrive in market [1-4]. Ocano-Higuera et al. [5] showed that on iced storage, ray fish maintains the good quality for 15 days. Besides, drying is another method to reduce the fish degradation. Generally drying is performed by spreading the fish on the mat or floor, and dried it directly under the sun [6]. This is a simple and cheap method of drying. A disadvantage of this method is the low quality of drying so another way to obtain better quality of dried fish is required. In this study, the method to be explored is one with tunnel drying.
