Abstract

Limbah hasil peternakan salah satunya bulu ayam yang dapat digunakan sebagai pakan alternatif untuk meminimalisir biaya pengeluaran untuk pakan ikan. Pakan merupakan salah satu faktor penting untuk menunjang pertumbuhan ikan sehingga butuh produksi yang sangat banyak. Tujuan penelitian ini untuk mengetahui efisiensi pemanfaatan bulu ayam sebagai pakan alternatif. Bulu ayam berpotensi dimanfaatkan sebagai pakan ternak karena memiliki kandungan protein yang tinggi, yaitu 80 - 90% dari bahan kering, melebihi kandungan protein kasar bungkil kedelai (42,5%) dan tepung ikan (66,5%). Potensi limbah bulu ayam di Indonesia kurang lebih sebanyak 167 ribu ton per tahun. Bulu ayam memiliki kandungan protein yang tinggi, tetapi protein bulu ayam merupakan jenis protein yang sulit dicerna oleh ikan karena tergolong protein keratin. Metode yang digunakan dalam mengolah limbah bulu ayam hingga menjadi pakan yaitu proses fermentasi yang melibatkan bakteri Bacillus yang dapat mendegradasi keratin. Fermentasi bulu ayam menggunakan bakteri dapat meningkatkan kadar protein kasar sebanyak 2-15%. Tepung bulu ayam fermentasi pada pakan dapat meningkatkan pertumbuhan ikan sebesar 2-5% lebih cepat.

Abstract

Feed additives are added in small quantities to improve feed quality and improve feed efficiency. Seaweed can be used as a feed additive because it contains nutrients such as protein, carbohydrates, fats, and minerals. One type of seaweed that can be used as a feed additive is Kappaphycus alvarezii. The step to maximize the nutritional content of seaweed flour is through fermentation. The purpose of this study is to determine the effect of the long fermentation time of bioflocculants on Kappaphycus alvarezii as an additive in feed for the growth and efficiency of goldfish feed utilization. This study used a Complete Random Design method with three treatments and four replicates, namely P0 (Fermentation 144 hours (6 days)), P1 (Fermentation 192 hours (8 days)) and P2 (Fermentation 240 hours (10 days)). The results showed that P2 treatment had a real effect on absolute weight, absolute length, specific growth rate, feed utilization efficiency (EPP), feed conversion ratio (FCR), but had no effect on the survival rate of goldfish. The best treatment in this study refers to the absolute length value, feed conversion ratio, and feed utilization efficiency, namely P2 treatment. Meanwhile, referring to the absolute weight value and specific growth rate, the P2 and P1 treatments were better than the P0 treatments.

Abstract

Abundant organic waste has the potential to pollute the environment, so proper management is needed so that organic waste can become an economically valuable material. Bioconversion by maggot Hermetia illucens (Black Soldier Fly) is one of the effective methods to process organic waste into animal protein sources that can be used as fish and livestock feed. BSF maggot is able to reduce organic waste up to 78.9% per day and has a protein content of 30-45% and fat 24-30%. The maggot life cycle involves several phases from egg to adult, with temperature playing an important role in this process. Maggot also shows great potential in improving fish growth and health, and can be used as an efficient and highly nutritious alternative feed ingredient.

Abstract

Chitin and chitosan are polysaccharides from the exoskeleton of crustaceans such as shrimp and crabs, chitin has several benefits if added to fish feed including functioning as a source of fiber that can improve digestion in fish, increase metabolism, and support the immune system of fish. However, with its high fiber content, chitin needs to be simplified into chitosan so that it is easier to process by the fish's digestive system, with the extraction method using chemical compounds, we can get pure chitosan that can be applied to fish feed. The purpose of this review is to determine the best dose of adding chitin or chitosan to fish feed, the method used is a descriptive method through a literature review study of various research journals. The effective dose obtained in this review is the addition of chitin around 0.04% - 8%, while for chitosan it ranges from 4% - 10%.

Abstract

Viral Nervous Necrosis (VNN), caused by betanodavirus, poses a serious threat to the aquaculture of hybrid grouper (Epinephelus fuscoguttatus × E. lanceolatus), with mortality rates reaching 100% in larval and juvenile stages. This study aimed to develop a VNN detection protocol based on Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) and nested PCR at the Brackishwater Aquaculture Development Center (BPBAP) in Situbondo, East Java, from February to April 2024. The methodology included necropsy for sampling brain and eye tissues, RNA extraction using a silica-based method, two-step amplification (RT-PCR and nested PCR), and visualization of results through 1.2% agarose gel electrophoresis. The findings revealed that 2 out of 10 hybrid grouper samples (20%) tested positive for VNN, with the detection of a specific 294 bp DNA band. The developed protocol demonstrated high sensitivity (CT values of 18–22 cycles) and optimal specificity, with no false-positive results. Temporal analysis suggested a periodic infection pattern with an 8-week interval. These results confirm the endemicity of VNN at BPBAP Situbondo and underscore the importance of early detection to prevent mass outbreaks. This study recommends implementing the protocol as part of a molecular-based disease surveillance system, along with further development using quantitative PCR (qPCR) for quantitative analysis. The findings are expected to support sustainable VNN control programs in hybrid grouper aquaculture.

Abstract

The maru fish, Channa marulioides, is one of the native fish species of Indonesia that inhabits the Kapuas River in West Kalimantan. In addition to being consumed by local people, maru fish also has an export market as an ornamental fish. The market demand for maru fish is still met from wild catches. Excessive exploitation and a lack of environmental carrying capacity will increasingly threaten the existence of the maru fish in the wild. The continuous population decline can lead to the extinction of fish species. Therefore, before extinction, domestication needs to be carried out through cultivation activities. Currently, the alternative feed commonly used in the maintenance of maru fish seeds is dry maggots. However, maggots have not been optimally used as the main feed. This study aims to evaluate the substitution of dry maggots with commercial pellets in maru fish seeds as an initial domestication effort. Maru fish seed maintenance was carried out for 90 days. The seeds come from natural catches in the Kapuas River, West Kalimantan. The study was conducted experimentally using a Completely Randomized Design (CRD). The treatment in this study was a combination of dry maggots and pellets. Treatment M100 (100 % dry maggot), Treatment M75P25 (75 % dry maggot + 25 % pellets), Treatment M50P50 (50 % dry maggot + 50 % pellets) and Treatment M25P75 (25 % dry maggot + 75 % pellets). Each treatment was repeated three times. The results showed that seeds maintained with 50 % dry maggot + 50 % pellet feed had the lowest final growth, final growth rate, feed efficiency and FCR compared to other treatments.

Abstract

The mangrove crab (Scylla spp.) is a high-value aquaculture commodity, where feed quality—particularly the binder component—significantly influences farming success. This article reviews the role of various binders in mangrove crab feed formulations, including synthetic binders such as carboxymethyl cellulose (CMC), natural binders (seaweed meal, agar, gelatin), and recent innovations such as fermented food waste and combinations with probiotics or black soldier fly larvae (BSFL) oil. Binders not only maintain feed stability in water but also affect growth, survival rate, feed efficiency (FCR), and immune response in crabs. Synthetic binders like CMC exhibit high stability (>24 hours) but are costly and less environmentally sustainable, whereas natural binders such as Gracilaria and agar offer a balance between stability, eco-friendliness, and additional nutritional benefits. The integration of binders with probiotics or BSFL oil has been shown to enhance immunity and growth performance. Binder selection should align with the farming phase—for instance, agar and gelatin are recommended for larval stages, while cornmeal and soy protein concentrate (SPC) are suitable for grow-out phases. This article also provides practical recommendations based on farming objectives, such as using natural binders to reduce water pollution or combining CMC with probiotics for intensive farming systems. This review is expected to serve as a guideline for farmers in selecting optimal binders to support efficient, cost-effective, and sustainable mangrove crab aquaculture.

Abstract

The objective of this research was to determine the decline in freshness of skipjack tuna stored at room temperature. Fish freshness testing was carried out using organoleptic tests such as eyes, gills, odor and texture of the fish, as well as counting the number of bacteria taken from the gills of skipjack tuna. Skipjack tuna was taken from 3 different markets in Mataram City. Observations on the fish were carried out twice, the first in the morning after the fish was taken from the market at 09.00 WITA and the second observation at 15.00 WITA. The results of the study showed that in the morning the skipjack tuna was in a condition of declining quality freshness, then during the day the quality of the skipjack tuna decreased further with a condition that was almost rotten. The results of observations of total bacteria also showed that in the morning the total bacteria had passed the predetermined threshold and during the day the number of bacteria increased until it could not be counted.
