Freshly caught wild marine fishes such as this group are highly perishable that strong preservation methods are required. The warm tropical climate and the geographic hindrance as an archipelago make the preservation efforts more intriguing. The conventional preservation method (cold storage) is usually energy intensive and not affordable for low-income fishermen. Other existing preservation agents were proven either expensive (eg. Lactic acid), or potentially hazardous for public health (eg. formaldehyde). An innovation to the preservation method is thus deemed necessary, in particular in a condition where fishing period has to be prolonged due to the long distance between the fishing ground location and the unloading site.
