Abstract

Grouper (Family Serranidae) is one of the betanodavirus hosts. Betanodaviruses can infect species in tropical, subtropical or cold climates. This is a major concern because it has been reported to infect a variety of marine fish, both farmed and wild fish. The disease caused by this virus is commonly known as Viral Nervous Necrosis (VNN) or Viral Encephalopathy and Retinopathy (VER). This VNN disease is characterized by vacuolar necrosis of cells found in the brain, retina and spinal cord, can cause up to 100% mortality in larvae and juveniles and can cause significant losses in older fish. Infected fish, both wild and farmed, can act as reservoirs (nesting sites and breeding grounds for viruses) and can be a source of infection for farmed species. The method used in this study was descriptive method, while the Lunar-Tailed grouper (Variola sp.) samples used in this study were groupers caught measuring 26-42 cm. VNN testing on groupers by taking target organs (brains and eyes) then fixing them in 95% Ethanol then PCR testing at the Virology Laboratory. The results of this study indicate a different prevalence in the two waters in Gorontalo.

Abstract

The rearing of Mojosari ducks in Indonesia has become increasingly important as an alternative source of animal protein. However, the high cholesterol content in duck meat presents a challenge to its consumption. This study aims to evaluate the effect of turmeric supplementation in feed on cholesterol levels in the liver, blood, and meat of Mojosari ducks, as well as the organoleptic quality of the resulting meat. The experiment utilized a factorial Randomized Completely Block Design (RCBD), where ducks were divided into four treatment groups based on turmeric dosage: 0%, 6%, 8%, and 10%. Parameters measured included cholesterol levels in the liver, blood, and meat, as well as organoleptic assessments of taste, aroma, texture, color, and tenderness of the meat. The results indicated that turmeric supplementation significantly reduced cholesterol levels in the liver, blood, and meat of the ducks, with the 8% and 10% turmeric groups showing the lowest cholesterol levels. Turmeric supplementation also improved the tenderness and color quality of the duck meat, although no significant differences were observed in taste and aroma. The reduction in cholesterol levels suggests the potential of turmeric as an effective feed additive for producing healthier duck meat that is more appealing to consumers. These findings have implications for the development of feed based on natural ingredients that can enhance duck meat quality and support the sustainability of the duck farming industry in Indonesia.

Abstract

Small pelagic fisheries play an important role in food security, coastal livelihoods, and local fishery economies in Indonesia. Sardinella fimbriata is one of the economically important small pelagic fish species widely utilized in coastal communities. However, increasing fishing pressure may alter population size structure and reduce reproductive sustainability. This study aimed to analyze the size structure, gonad maturity stage, and exploitation status of Sardinella fimbriata in Kwandang Waters, Tomini Bay, Indonesia. The research was conducted from August to November 2025 using a descriptive quantitative approach. A total of 1,560 fish samples collected from commercial landings were measured for total length and examined macroscopically for gonad maturity. Data were analyzed using length-frequency distribution, maturity proportion, and logistic regression to estimate length at first maturity (L₅₀). The results showed that fish length ranged from 8.0 to 19.9 cm and was dominated by the 12.0–15.9 cm size group, accounting for 75.45% of total samples. Immature gonads dominated the catch, representing 91.35% of individuals, while mature fish accounted for only 8.65%. Logistic regression estimated L₅₀ at 16.72 cm, whereas the average catch length was 13.56 cm with an Lc/L₅₀ ratio of 0.81. These findings indicate that most fish were captured before reaching reproductive maturity, suggesting growth overfishing conditions. The study highlights the importance of minimum catch size regulation, selective fishing gear, and routine biological monitoring to support sustainable management of small pelagic fisheries in Tomini Bay.

Abstract

Food safety of fresh fish is an important concern because fish is highly perishable and may be misused with hazardous preservatives such as formalin. This study aimed to determine formalin content and analyze the relationship between length and weight of Nile tilapia (Oreochromis niloticus) and formalin levels in traditional markets of Gorontalo City. The study was conducted from January to February 2026 in five traditional markets, namely TPI Tenda, Moodu, Potanga, Andalas, and Sentral. Nile tilapia samples were analyzed using a formaldehyde test kit, and formalin levels were expressed in ppm. Total length and fish weight were measured, and the relationship between physical size and formalin content was analyzed using Pearson correlation. The results showed that all Nile tilapia samples tested positive for formalin, with concentrations ranging from 0.11 to 0.23 ppm. The highest formalin levels were found in TPI Tenda and Moodu, each at 0.23 ppm, while the lowest level was found in Sentral at 0.11 ppm. Fish length ranged from 19.43 to 25.61 cm, while fish weight ranged from 0.17 to 1.78 g. The correlations between length and formalin content and between weight and formalin content were both very strongly negative, with r = -0.97. These findings indicate that smaller fish tended to contain higher formalin levels. Market supervision, trader education, and formalin-free fish handling practices should be strengthened to protect consumer health.

Abstract

Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

Abstract

High feed costs remain a major constraint in Nile tilapia (Oreochromis niloticus) aquaculture, requiring alternative feed formulations based on local ingredients with adequate nutritional quality. This study aimed to evaluate the proximate composition of fish feed formulated from snail meal, Azolla meal, and turmeric as a phytobiotic supplement. The study used an experimental method with a Completely Randomized Design consisting of three treatments and three replications. The feed formulations were P1, consisting of 55% snail meal, 25% Azolla meal, 5% turmeric, 10% corn flour, and 5% tapioca flour; P2, consisting of 39% snail meal, 39% Azolla meal, 7% turmeric, 10% corn flour, and 5% tapioca flour; and P3, consisting of 25% snail meal, 51% Azolla meal, 9% turmeric, 10% corn flour, and 5% tapioca flour. The analyzed parameters included protein, moisture, fat, ash, crude fiber, and carbohydrate contents. Data were analyzed using analysis of variance followed by the Least Significant Difference test. The results showed that feed formulation significantly affected all proximate parameters. P3 produced the highest protein content of 43.87%, fat content of 3.68%, crude fiber of 3.11%, and carbohydrate content of 7.28%, while also producing the lowest ash content of 28.46%. Moisture content ranged from 1.11% to 1.30%, indicating good feed storage stability. These findings demonstrate that the integration of snail meal, Azolla, and turmeric can improve the nutritional quality of alternative Nile tilapia feed and support locally based sustainable aquaculture feed development.

Abstract

The use of local raw materials in Nile tilapia feed formulation needs to be developed to reduce dependence on increasingly expensive conventional feed ingredients. This study aimed to analyze the effect of different formulations of chicken feather meal and moringa leaf meal with turmeric addition as a phytobiotic on the chemical composition of Nile tilapia (Oreochromis niloticus) feed. The study used a completely randomized design with three treatments and three replications. P1 consisted of 55% chicken feather meal, 25% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; P2 consisted of 40% chicken feather meal, 40% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; and P3 consisted of 25% chicken feather meal, 55% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch. The parameters analyzed were crude protein, moisture, ash, crude lipid, crude fiber, and carbohydrate. Data were analyzed using analysis of variance followed by the least significant difference test when significant differences occurred. The results showed that P3 produced the highest protein content (22.60%), ash content (6.65%), crude fiber (6.55%), and carbohydrate (8.45%), whereas P2 produced the highest lipid content (6.54%). Based on chemical analysis, P3 was the most prominent formulation for most proximate parameters. However, this formulation cannot be directly concluded as the best feed for fish growth because digestibility, palatability, feed conversion ratio, growth, survival, and health responses were not evaluated. Further biological testing is therefore required to confirm its feasibility for Nile tilapia culture.

Abstract

Odot grass (Pennisetum purpureum cv. Mott) is an important ruminant forage because of its high palatability, adaptability to tropical environments, and potential for high biomass production. This study aimed to evaluate the effect of solid organic fertilizer on the growth and production of odot grass as a basis for developing productive and sustainable forage cultivation. The experiment was conducted in Pangi Village, Dulupi District, Boalemo Regency, from February to March 2026 using a completely randomized design with five treatments and three replications. The treatments consisted of P0 without solid organic fertilizer, P1 at 10 t/ha, P2 at 20 t/ha, P3 at 30 t/ha, and P4 at 40 t/ha. Observed variables included plant height, leaf number, tiller number, and fresh weight production. Data were analyzed using analysis of variance followed by Duncan’s multiple range test at the 5% significance level. The results showed that P4 produced the best response for all measured parameters. The highest plant height was 77.83 ± 43.80 cm, with 18.83 ± 3.67 leaves, 2.42 ± 1.38 tillers, and fresh weight production of 52.33 ± 10.12 t/ha. These improvements indicate that 40 t/ha solid organic fertilizer enhanced nutrient availability and supported biomass formation. Solid organic fertilizer is therefore a promising locally based cultivation input for improving ruminant forage productivity.
