Utilization of Fish Scales for Non-Food Products : A Review
No full textThis article aims to review the potential of fish scale waste as a processed material and its application to various fields of the non-food industry. The method used in this process is a qualitative descriptive method using data collected from secondary sources. Fish scales are residual waste that can be obtained from waste created in fish sales or fish processing companies. This type of waste has the potential to be utilized because it contains various kinds of organic materials that can be reprocessed to become new products. Fish scales waste can be used directly into handicraft products, including brooches, beading (sequins) and used indirectly in the form of products from collagen extraction, including fish glue and products from chitosan fish scales, including bioplastics, biocoagulants, and Rhodamin B dye adsorbents. The importance of utilizing fish scale waste is that it can increase the selling value of fish scales which were once just waste into potentially useful materials, reduce environmental pollution, encourage the concept of a green economy, and create a zero waste environment in the fishery product industry. From the data that has been collected, it can be concluded that fish scale waste can be used in various non-food industries and can be processed into various products, this includes the use of fish scales as craft products such as brooches or key chains, processing fish scales into adhesives, and extraction of chitin from fish scales to be used as additives for bioplastics, biocoagulants, and rhodamine b adsorbents

The Possibility of Using Probiotics in the Aquaculture of Freshwater Fish
No full textListed as one of the highest producer of aquaculture fish, Indonesia’s fisheries sector holds a promising potential to be developed as source of global food security. The total production value of both inland and marine farming from both fish and non-fish species were reported to be increased each year. The current government targeted to excel the production up to 25% by 2024. To support this, many innovation and research have been done to accelerate the production of cultured fish, especially fresh water fish which demand is always high in the market. Several fresh water fish commodities have a poor growing performances, such as growth rate, feed conversion ratio (FCR) and survival rate. Thus, a probiotics were used to boost their performance. Probiotics is known for their ability to enhance the growth of fish by secreting enzyme which beneficial to breakdown complex compounds, making it easier to digest for the fish. It is also commercially widespread in the market in various form, either incorporated to the feed or directly use to the medium. In this review, a comprehensive analysis of how probiotics help to increase aquaculture efficiency of fresh water fish will be thoroughly discussed. The discussion will be focus on three fresh water fish species, which are Gouramy fingerlings (Oshpronemus gouramy) Siamese catfish (Pangasius hypopthalmus) And Nilem fish (Osteochillus hasselti)
