lautnusantara.com Fish scales are structures that cover the fish's body and function as protection from the surrounding environment. Processing fish scale waste into accessories is one innovation in the environmentally friendly use of organic waste. Fish scales contain keratin and calcium phosphate, which makes them strong, light and naturally shiny, suitable for making various types of accessories such as earrings, bracelets, necklaces, brooches and clothing decorations.

Fish scale waste crafts are handicrafts made from fish scales. However, not all fish scales can be used as basic craft materials. According to the book Building Oceans Building People by Dr. Suseno Sukoyoso (2019: 72), apart from crafts, fish scales actually also have benefits that are no less important, such as absorbing chromium and making medicines.

This craft has been around for decades. The emergence of this fish scale craft is claimed to be able to reduce fish scale waste which is often wasted.
