Abstract

The study was conducted to investigate the growth of juvenile whiteleg prawn (Penaeus vannamei) fed with different doses of the crown of thorns starfish (Acanthaster planci) meal in formulated diets. The study was designed using a completely randomized design consisting of four treatments and three replications.  The treatments were the dosages of A. planci meal in a formulated diet, namely A: 0% (control); B: 9%; C: 18%; and D: 27%. Juveniles of P. vannamei were reared in a 40 × 25 × 25 cm3 aquarium (15 Liter water volume) for 28 days. The results showed that the Individual Weight Gain (IWG) of juveniles ranged from 2.68 to 2.94 g, Specific Growth Rate (SGR) ranged from 2.82 to 2.93% day-1, feed conversion ratio ranged from 3.03-3.22, feed efficiency was 31.31-33.17%, and survival rate was 96.67-100%.  The analysis of variance revealed that the use of A. planci meal in a formulated diet did not have a significant effect (p>0.05) on growth performance (IWG and SGR), feed conversion ratio, feed efficiency and survival rate of juveniles of whiteleg prawn during 28 days of culture. The utilization of A. planci meal up to a dose of 27% can be used as a substitute for fishmeal as a source of feed protein for cultured whiteleg prawns.

Abstract

The price of ornamental fish is determined by the quality of the color of ornamental fish, but in general, the color of ornamental fish will fade when maintained in an aquarium container. The purpose of this study was to determine the color pigment content of koi fish (Cyprinus rubrofuscus) after being given additional feed in the form of seagrass leaf waste flour Thalassia hemprichii.  This research was conducted for 28 days. This study used a completely randomized design (RAL) with 5 treatments and 3 replicates so that in this study there were 15 experimental units. The treatment in this study was the addition of seagrass leaf waste flour to fish feed. P1 (control), P2 (addition of 3% seagrass leaf waste flour), P3 (addition of 6% seagrass leaf waste flour), P4 (addition of 9% seagrass leaf waste flour), and P5 (addition of 12% seagrass leaf waste flour). The results showed that the value of color pigment content in all treatments were P1 21.56 µmol/g, P2 22.75 µmol/g, P3 23.49 µmol/g, P4 22.08 µmol/g and P5 25.76 µmol/g. For absolute growth in all treatments, P1 was 1.37 g, P2 1.53 g, P3 1.80 g, P4 2.73 and P5 3.70 g. For absolute growth in all treatments, P1 was 53%, P2 67%, P3 67%, P4 80% and P5 87%. The survival rate of ornamental Koi (C. rubrofuscus) in all treatments was P1 53%, P2 67%, P3 67%, P4 80%, and P5 87%. This research concludes that the color pigment content of ornamental Koi (C. rubrofuscus) increases after feeding additional doses of T. hemprichii and the best color pigment increase is shown by treatment P5 with the addition of a 12% dose of T. hemprichii, namely 25.76 µmol/g.

Abstract

Bacteria found in the digestive tract of shrimp mostly play a major role in nutrient absorption. One of the nutritional contents that is quite difficult for shrimp to absorb is fiber. Bacteria that can degrade fiber content are known as cellulolytic bacteria. This study aimed to determine the activity index of cellulolytic bacteria found in the digestive tract of shrimp. The research method includes sampling shrimp with three different categories based on average length and weight, divided into three categories such as large (22.2 g ± 87.3 cm), medium (17.1 g ± 36.7 cm), and small (13.4 g ± 18.8 cm) taken from the north coast waters of Pemalang and the south coast waters of Cilacap. Furthermore, bacterial isolation, morphological observation, calculation of bacterial abundance, and testing of cellulolytic activity were carried out. The results showed that 150 bacteria were successfully isolated from both locations at different sizes and a total of 68 bacterial isolates had cellulolytic activity. There were 22 potential isolates from each coastal water that had a great cellulolytic activity index, ranging from 1.4 to 7.0. Moreover, the most potential activities were performed by 8 bacterial isolates encoded with GM.1, GM.2, GM.3, GM.4, GM.5, GM.6, GM.7, and GM.8 with a range of cellulolytic index obtained ranging from 3.0-7.0. The high activity index of the cellulolytic bacteria obtained is a fairly promising potential as a probiotic candidate that plays a role in degrading fiber in food found in the digestive tract of shrimp so that it can accelerate its growth.

Abstract

Royal Whiptail Catfish (Sturisoma panamense) have high-stress levels in the early stages of their life. This is a significant concern in the field of fish farming. One of the crucial factors in the cultivation of royal whiptail catfish is the addition of vegetable or algae protein to the feed according to the habits of herbivorous fish. This study aimed to determine the best dose of spirulina that can enhance the growth and survival rates of royal whiptail catfish fry. There were four treatment groups, i.e. feed without spirulina (K), a dose of 3% (SP-3%), a dose of 6% (SP-6%), and a dose of 9% (SP9%). The study was conducted at the Tetra Aquaria Company in Sukabumi City in April - May 2024. The spirulina culture was dried in an oven at 60 ℃ for 24 hours and ground using a mortar. The powdered feed was mixed with spirulina according to the treatment dose. The fish larvae used were newly hatched larvae, and the maintenance period during the treatment was 21 days. The maintenance container uses a tray measuring 40 cm x 30 cm x 15 cm. The study results showed that the best group was SP-6% with an average survival rate of 87% ± 4.62, significantly different compared to the K, SP-3%, and SP-9% treatments. The daily growth rate value of SP-9% showed the best significant difference (P <0.05) from the control treatment and 3% dose, however not significantly different (P> 0.05) with SP-6%.

Abstract

Koi fish aquaculture sector is closely tied to risk. Various factors, such as delays and uncertainties in delivering feed, infections, and pests affecting the koi fish due to irregularities in pond cleaning, delays and improper feeding, and extreme weather conditions, can lead to the death of fish. It is crucial to monitor the increasing risks diligently, as inadequate risk management procedures can lead to losses and potentially disrupt the growth of the industry. The purposes of this risk management on koi fish hatchery production are: 1). Identify and define risk events and risk agents in koi fish farming production in Kediri Regency, 2). Analyze risk events and risk agents in the production of koi fish in Kediri Regency. 3). Analyzing risk management in koi fish aquaculture in Kediri Regency. The proportional sampling method was used to choose the research sample. The House of Risk (HOR) data analysis method was employed in this study to analyze data. Based on the data analysis, a total of 17 risk events were identified in the four processes of koi fish seed production, which consist of risk events in the pond preparation process, risk events in the spawning process, risk events in the maintenance process, and risk events in the harvesting process. These risk events are caused by 33 risk agents.

Abstract

Common carp (Cyprinus carpio) is one of the main commodities of aquaculture production in Indonesia, especially West Java. The processing of Lemna through the fermentation process is one of the efforts to improve quality alternative feed ingredients that function as prebiotics. The growth of common carp infected with the disease tends to be disturbed, so that the growth rate is inhibited. This study aims to determine the effect of the level of addition of Lemna minor flour from the enrichment of BIOMS probiotics in feed on the growth of common carp infected with Aeromonas hydrophila bacteria. The method used in this study was a Complete Randomized Design (CRD) experiment with 5 treatments and 4 replicates. The calculation of the measurement of test fish samples was carried out 4 times for 30 days. The data was analyzed using variety analysis (ANOVA). The conclusion of this study is that the addition of Lemna flour enriched with fermented BIOMS probiotics in feed provides an increase in SGR (Specific Growth Rate) value, a decrease in FCR (Feed Conversion Rate) value, and an increase in FE (Feed Efficiency) value of fish that is better than fish fed commercial feed (control +) and lemna without enrichment (control -). Feeding with the addition of fermented Lemna flour can increase the growth of common carp, such as SGR (0.34 ± 0.0599) and EP (68%), as well as reduce the FCR value (1.51 ± 0.3161).

Abstract

Growth performance, survival, nutrient utilization, body composition and profitability of Clarias gariepinus fed with imported extruded (Le), locally pelleted (Lpe) and locally extruded (Lex) feeds and reared under two production facilities was investigated. The study was conducted in nine IBC tanks and nine net hapas in installed in a 500m2 earthen pond with holding water capacity ranging from 0.8 to 0.9 m3. For each system, 900 juveniles of mean initial weight ranging from 10.68 ± 4.93 g to 15.15 ± 3.48 g were stocked at 100 juveniles holding system-1 and were fed thrice a day for 16 weeks. Final mean weights for tank system were respectively ranged from 758.46 ± 13.79g, 289.03 ± 60.67g and 339.27 ± 9.34g for Le, Lpe and Lex feeds. As for hapas-in-pond system, final mean weights were 726.02 ± 82.91g, 396.85 ± 18.96g and 461.73±13.26g respectively for Le, Lpe and Lex feeds. Fish fed with “Le” exhibited significantly higher growth performance and better nutrient utilisation (p<0.05) irrespective of the production system. However, fish fed “Lpe” and “Lex” feeds exhibited higher (p<0.05) growth performances in hapas-in-pond system. The economic assessment revealed that the use of “Le” feeds to feed African catfish was economically efficient as indicated by the lower incidence cost and higher profit when compared to the local feeds. The fact that the studied feeds were profitable as indicated by the benefit cost ratio >1 irrespective of the production system proves that if the ingredients used to formulate the local feeds are correctly formulated and blended properly, these feeds can provide similar growth rates, survival and yields of African catfish similar to imported feeds.

Abstract

Increasing stocking density in catfish cultivation is part of efforts to increase production to meet catfish needs nationally and internationally. The obstacles faced by household scale cultivators when applying high stocking densities are poor water quality, high feed conversion, slow growth and high mortality. Many novice cultivators on a household scale are tempted by high production results by implementing very high stocking densities, but do not yet understand the cultivation techniques well. This research aims to determine the optimal stocking density for cultivating catfish on a household scale using round tarpaulin ponds. The study used a completely randomized design of four treatments with three replications (250 fish/m3, 500 fish/m3, 750 fish/m3 and 1000 fish/m3). The cultivation container used is a tarpaulin pool with a diameter of 3 meters, and the fish are given commercial feed with 28-33% protein. Production results are also analyzed using the business income analyst model. A stocking density of 500 fish/m3 produces the most optimal production values, namely absolute growth of 4.28 ± 0.02%/day, absolute length growth of 12.4 ± 0.9 cm, survival of 85.97 ± 0.56%, feed conversion of 0.95 ± 0.00, and production of 30.4 ± 0.57 kg/m3 with operating income of Rp. 1,258,967,-. The results of the analysis of production and income values show that treatment with a density of 500 fish/m3 is the best stocking density for cultivating catfish on a household scale using tarpaulin ponds.

Abstract

The blue mosaic guppy (Poecilia reticulata), a highly sought-after freshwater ornamental fish, faces growing market demand. This study evaluates the technical feasibility and profitability of blue mosaic guppy production at Swasti Farm in Sleman, Yogyakarta, Indonesia. Using a case study approach, data were collected through participatory observation, direct monitoring, and semi-structured interviews. Technical performance was assessed by benchmarking farm practices against Indonesian National Standards (SNI 8228.3:2015, SNI 9308:2024) and existing literature. Profitability analysis utilized a one-year business projection model incorporating key metrics: Revenue-to-Cost (R/C), net profit (NP), Break-Even Point by sales volume (BEPs) and production units (BEPu), and Profitability Rate (PR). Production followed four stages: broodstock rearing, breeding, fry/nursery rearing, and harvesting. Rigorous water quality and fish health management ensured protocol compliance. Broodstock (aged three months at spawning) were maintained at a 1:2 male-to-female ratio, yielding 20 larvae per cycle and a 55% survival rate post-nursery. Financial analysis revealed an annual net profit of IDR 9,826,417, with R/C = 1.3, BEPs = IDR 24,419,940, BEPu = 70 fish pairs, and PR = 141%, confirming economic viability. To enhance profitability, scaling production by 75% (to ≥210 fish pairs annually) and optimizing operational efficiencies could elevate profits above Sleman, Yogyakarta’s minimum wage threshold. Findings demonstrate that standardized practices and strategic scaling align guppy farming with regional economic benchmarks, offering a replicable model for small-scale aquaculture ventures.
