Academic Letters is a new experiment in open access academic publishing. We aim to publish short-form articles such as brief reports, case studies, reports of new findings, socio-political critiques, credible scholarly opinions, and ideas omitted from previously published works. Articles published in Academic Letters are no longer than 600-1500 words, excluding references. Academic Letters is published periodically (6 issues per year: January, March, May, July, September, and November).

Abstract

Feeding enriched with commercial probiotics is one solution to overcome the challenges in intensive catfish farming, especially related to the high cost of feed. Adding probiotics to feed can help reduce production costs while speeding up harvest time. Commercial probiotics containing bacteria such as *Lactobacillus*, *Acetobacter*, and *yeast* have been proven to be very effective in supporting catfish growth. Based on the advantages that have been revealed in various studies, the use of commercial probiotics is feasible to be applied and further developed in intensive catfish farming.

Abstract

Grouper fish are widely distributed in coastal waters, both in tropical and subtropical regions, and are a type of fish that lives in coral habitats, so they are often referred to as reef fish. In Indonesia, there are various types of grouper fish, one of which is the humpback grouper (Cromileptes altivelis), which is popular because of its high economic and ecological value. This article briefly explains about humpback grouper, both in terms of morphology, habitat, reproduction and spawning.

Abstract

Tilapia (Oreochromis niloticus) is one type of fish that is widely sought after by the public as a source of animal protein, because its meat is thick and its taste is delicious. In addition, this fish has great potential for cultivation because it is able to adapt to various environmental conditions, including tolerance to a fairly wide range of salinity. This article briefly explains the morphology, habitat, eating habits and growth of tilapia.
Research Perspective: The Advantages of Using Plant-Derived Flavonoids as Natural Treatments in Aquaculture Compared to Not Using Them Muh. Sulaiman Dadiono; Sri Andayani; Sutrisno Adi Prayitno; Aminin; Rima Oktavia Kusuma

Show Abstract | Download Original | Original Source | Check in Google Scholar | DOI: 10.64781/620743

Abstract

Productivity in aquaculture activities is often reduced due to disease outbreaks caused by various pathogens, including bacteria, viruses, and parasites. As an alternative to chemical treatments, a natural, plant-based approach—particularly through the utilization of flavonoid compounds derived from medicinal herbs—is being developed as a safer and more sustainable solution. This paper presents the author’s perspective, based on previous research, on the advantages of using plant-derived flavonoids for the treatment of cultured fish and discusses the potential negative impacts that may arise if such compounds are not integrated into aquaculture systems.

Abstract

Gresik Regency, recognized for its rich fishery resources, is experiencing growing difficulties associated with unmanaged fish waste, which has detrimental effects on both the environment and community health. The "Umami Sea" program presents an eco-friendly approach by converting by-products from fish processing—like bones, skin, and offal—into valuable flavoring products through protein hydrolysis. This development is in line with the blue economy principle, focused on lowering marine pollution, creating local revenue, and reducing reliance on artificial additives such as monosodium glutamate. By applying circular economy strategies, fish waste is evolved into a valuable resource, promoting community-led businesses and strengthening economic stability. The initiative encourages the involvement of coastal communities, including fishermen, small and medium-sized enterprises, and young people, while advocating for healthier, sustainable food options. Underpinned by research, technology sharing, and partnerships among local authorities, universities, and non-governmental organizations, "Umami Sea" serves as a model that can be replicated for sustainable management of fisheries waste. Its advancement not only boosts local economies but also reflects global movements toward eco-innovation and sustainable growth in marine sectors.
