Abstract

The untapped potential of fish processing production waste as a source of fish feed ingredients makes it a promising resource due to its widespread availability. This study aims to evaluate the process of producing fish waste silage through probiotic fermentation to assess the resulting quality post-fermentation. Employing an exploratory descriptive method, this research draws from diverse literature sources, encompassing books, national journals, and international publications. The comparison of findings from prior research indicates that fermenting fish waste with microbes, particularly lactic acid bacteria, enhances its protein content, positively impacting fish growth performance. Introducing silage at a 10% dose achieves a tilapia survival rate of 83.33%, while a 25% silage addition yields a relative growth rate of 222.63% for catfish and a feed conversion ratio of 1.06 for tilapia.Keywords:FermentationFish wasteFish silageLactic acid bacteria

Abstract

The aquaculture sector in Indonesia faces significant challenges due to the reduction of productive land and the degradation of surface water quality. This study aims to evaluate the effectiveness of transforming conventional earthen pond cultivation systems into Recirculating Aquaculture Systems (RAS) through a comprehensive analysis of land and water use efficiency. The method employed is a quantitative and qualitative descriptive approach via systematic literature review (SLR), adapting the PRISMA guidelines. Secondary data were extracted from 10 primary scientific articles published between 2016 and 2026. The results indicate that RAS technology enables extreme intensification of stocking density up to 2,000 fish/m³, significantly outperforming conventional earthen ponds (±100 fish/m³). The filtration system in RAS is proven to maintain optimal water quality stability, with very low ammonia levels (<0.01 mg/L) and high dissolved oxygen (6.0–7.2 mg/L). These conditions drive the Specific Growth Rate (SGR) to reach 2.68% and optimize the Food Conversion Ratio (FCR) to 1.08. Economically, despite high initial capital expenditure, RAS demonstrates long-term feasibility with a Payback Period of less than 4 years at an optimal commercial scale. In conclusion, the transformation to RAS technology is a strategic solution that offers superior technical, biological, and economic benefits, while ensuring ecosystem sustainability through a zero-waste concept.

Abstract

Feed availability is a crucial factor in aquaculture, accounting for approximately 6070% of total production costs. High-quality feed is often expensive due to reliance on imported ingredients. To address this issue, animal-based organic waste presents a promising alternative, given its abundance, underutilization, and high nutritional value when properly processed. This review was conducted from November 2024 to January 2025 using a narrative literature review approach, synthesizing previous publications to identify research gaps and development opportunities. Literature was sourced from national and international scientific databases, including Scopus, ScienceDirect, SpringerLink, and ResearchGate. The study aimed to explore the production of fermented animal by-product meal and its application in aquafeed to enhance fish growth performance. Findings indicate that fermentation significantly improves the nutritional quality of animal waste. Several reviewed studies reported that incorporating fermented by-products such as fish offal, poultry feathers, and blood at inclusion levels of 2025% can improve the growth and survival rates of juvenile fish. Therefore, the optimal use of such ingredients is recommended to reduce feed costs and support the sustainability of aquaculture systems.Keywords:Alternative ingredientsFish wasteChicken Feather WasteBlood WasteFermentationFish feed

Abstract

Aquaculture activities cannot be separated from the availability of artificial feed, even 70% of the total production cost is spent on feed, so the availability of good feed, in terms of quality and quantity, is an effort to maintain the success of aquaculture activities. Feeds with high protein have relatively higher prices because some of their raw materials still rely on imports from other countries. The solution to this problem is to use alternative feed ingredients that have good nutritional content, are easy to obtain and do not compete with humans. Organic waste originating from food scraps and agricultural industry residues has considerable potential. However, it is necessary to have a fermentation process as an effort to improve the nutrition and quality of these materials. The purpose of this paper is to determine the extent of utilization of fermented organic waste as fish feed ingredients that can help improve fish growth performance.Keywords:Alternative feed ingredientsFermentationFish feedOrganic waste

Abstract

The high level of public consumption, balanced with the increasingly dense population globally, makes food waste more and more. Food waste is the second-largest contributor to waste in the world. Moreover, the lack of food waste management makes this condition even worse. This food waste can be found, one of which is in restaurants, school canteens, food courts, and others. Fermentation is the process of breaking down complex substances into simpler ones. A fermentation process can help process food waste into various products such as liquid organic fertilizer, compost, biogas, and raw material for fish feed. Through the fermentation process, food waste can be used as an alternative fish feed with high nutritional content to benefit fish cultivators. Fish need many nutrients for their bodies, with food waste that has been processed will meet the dietary needs of fish. The cultivators will benefit more from the cost of feed and the sale of fish that can meet consumer needs.Moreover, the demand for the fish market is increasing every year. Several factors play a role in the success of the food waste fermentation process and the quality of the resulting product to be converted into fish feed raw materials. These factors include incubation time, pH acidity, and microbial factors that can accelerate the spoilage of fish feed raw materials.Keywords:Fermentation,Restaurant wasteFish feedFactorsQuality of feed IngredientsLiterature review on fermentation factors of restaurant organic waste affecting feed quality

Abstract

The increasing demand and consumption of fish food from year to year means that demand for raw materials also increases. Vegetable raw materials can be an alternative because they have a relatively longer shelf life, are easy to find and are relatively cheap. Vegetable raw materials are raw materials that come from plants such as grains and nuts. Vegetable raw materials that exist in nature are usually reprocessed into feed with better nutritional content, so it is necessary to maintain the feed ingredients so that their content remains long-lasting. The raw materials used are soybeans, corn, sword beans, peanuts, kapok seeds and jackfruit seeds. Vegetable raw materials require physical processing to change texture, taste and other properties. Physical processing such as grinding, mixing, drying, soaking, steaming aims to increase nutrient availability, reduce anti-nutrients, extend the shelf life of vegetable raw materials, and improve the texture and taste of feed. Physical processing also plays a role in increasing the digestibility of vegetable ingredients, reducing the risk of microbial contamination, and extending the shelf life of fish feed. By optimizing physical processing techniques, plant feed can be produced that is efficient, high quality, and supports healthy growth and sustainable productivity of farmed fish. The use of vegetable raw materials for fish is starting to be widely used because it has good protein, for example the use of peanuts in fish feed which produces the best growth rate values, namely 0.7% and feed efficiency of 16.76%.

Abstract

Sangkuriang catfish (Clarias gariepinus) is one of the most commonly cultivated freshwater fish species in Indonesia. The high production of catfish is largely due to the efforts of fish farmers who are able to produce sufficient quantities to meet the increasing consumption demand. One of the aquaculture methods used is the BUDIKDAMBER system, which involves fish farming in buckets with high stocking densities. This study employed an experimental method using a Completely Randomized Design (CRD) consisting of 3 stocking density treatments with 4 replications: A (1 fish/liter), B (2 fish/liter), and C (3 fish/liter) for a period of 30 days. The fish were kept in buckets prepared for the budikdamber activity, with stocking densities adjusted according to each treatment, and were fed three times a day. Water quality was monitored every 3 days. The results of the study showed that up to a density of 3 fish/liter of Sangkuriang catfish fingerlings, there was no significant difference among the different stocking density treatments, and all treatments still demonstrated good performance. The best treatment was found in treatment C (3 fish/liter), with a survival rate of 77.25%, a feed conversion ratio (FCR) of 0.67, and a specific growth rate (SGR) of 3.28%.
