Abstract

Background: Diatoms require silicate for frustule formation and optimal cell division, making silicate availability a critical factor in improving microalgal production for aquaculture. Thalassiosira sp. is one of the most widely used live feeds in shrimp hatcheries because of its high nutritional value and suitable cell size for larval consumption.Aims: This study evaluated the effects of different silicate concentrations on the growth performance of Thalassiosira sp. by simultaneously assessing cell density, specific growth rate (SGR), and division rate (DR).Methods: A completely randomized design with four treatments was employed: control (without silicate), 15 ppm (SL15), 20 ppm (SL20), and 25 ppm (SL25), each with three replicates. Cell density was monitored daily for 14 days using a haemocytometer, while SGR and DR were calculated from the exponential growth model.Results: The results showed that silicate supplementation significantly affected all growth parameters (p < 0.05). The highest cell density (4.60 × 10⁶ cells mL⁻¹) was obtained in the SL25 treatment on day 12, whereas the highest SGR (29.17 ± 0.32% day⁻¹) and DR (0.422 ± 0.005 divisions day⁻¹) were recorded in SL20. However, Duncan's Multiple Range Test indicated no significant differences between SL20 and SL25 for SGR and DR, suggesting comparable physiological responses at these silicate concentrations. These findings indicate that silicate concentrations between 20 and 25 ppm provide the optimal range for enhancing the growth performance of Thalassiosira sp. and may improve the efficiency of live-feed production for shrimp hatchery applications.Conclusion: Silicate supplementation significantly improve the growth performance of Thalassiosira sp., as reflected by increased cell density, specific growth rate, and division rate.

Abstract

The provision of quality and sufficient shrimp fry for production is largely determined by the management of maintenance during larval stadia. This study aims to obtain the best treatment of natural feed in the form of Spirulina sp. and Artemia sp. as feed supplements to improve the growth performance and survival rate of patin fish larvae. The experiment used a Complete Randomized Design consisting of 4 feed treatments and 3 replicates: A (Artemia sp. 100%), B (Artemia sp. 100% and Spirulina sp. 100%), C (Artemia sp. 50% and Spirulina sp. 50%), and D (Spirulina sp. 100%). The larvae with a density of 50 heads/L were kept in the aquarium and fed according to the treatment. The density of Spirulina sp. administered was 104–105 cells/mL maintained until day 7 according to the treatment. The parameters measured included growth performance, which included specific growth rate (SGR), survival (SR), absolute length growth (PPM), and analysis of larval digestive enzymes (amylase, lipase, and protease). The data were analyzed using one way-analysis of variance and continued with Duncan's Multiple Range Test with a 95% confidence interval using SPSS version 22.0. The results showed that the administration of Spirulina sp. produced better SGR, SR, PPM, amylase enzyme, lipase, and protease activities compared to the control (100% administration of Artemia sp.). The best treatment was given by 100% Spirulina sp. treatment. Keywords: Artemia sp., digestive enzymes, patin fish larvae, Spirulina sp.

Abstract

Tor soro is a freshwater fish species with high economic and ecological value. However, adequate production does not support the increasing demand for its fry, primarily due to its slow growth performance. One potential approach to overcome this limitation is feed enrichment with B-complex vitamins. This study aimed to evaluate the optimization of growth performance in T. soro fry through dietary supplementation of B-complex vitamins. The experiment was conducted using a Completely Randomized Design (CRD) with two treatments and three replicates: VT0 (0 g kg⁻¹) and VT1 (2 g kg⁻¹). Fish were reared for 60 days in aquaria (60 × 30 × 35 cm³). The results demonstrated that VT1 significantly improved (p < 0.05) both growth and feed performance. Absolute length and weight gain reached 2.85 ± 0.10 cm and 1.29 ± 0.03 g, while specific and daily growth rates were 3.96 ± 0.03% and 2.16 ± 0.05 g day⁻¹, respectively. Moreover, supplementation of B-complex vitamins reduced feed utilization, as indicated by feed conversion ratio (FCR) and feed efficiency values of 2.75 ± 0.06 and 36.43 ± 0.81%, respectively. These findings suggest that feed enrichment with B-complex vitamins can effectively enhance the growth performance of T. soro fry.

Abstract

Water quality plays an important role in sustainable agriculture. Water quality also affects the quality and quantity of fishery production. In ornamental fish cultivation, water quality influences not only production, but also the shape and color of the fish. To achieve optimal results, water quality parameters need to be maintained. Manually monitoring water quality parameters faces many challenges such as being time-consuming and not providing real-time data. This study investigated the application of Artificial Neural Networks (ANNs) in classifying water quality status. This status is based on data collected using sensors in an Internet of Things (IoT)-based monitoring system. The dataset comprised five key parameters: pH, temperature, ammonia, total dissolved solids (TDS), and total suspended solids (TSS). This data was collected from aquariums cultivating the Denison barb (Sahyadria denisonii). Data preprocessing was performed using feature standardization. This aims to improve model performance. The ANN model was constructed with two hidden layers (32 and 16 neurons). This model was trained using the Adam optimizer, with categorical cross-entropy as the loss function. The dataset was divided into 80% for training and 20% for testing. The trained ANN model achieved an accuracy of 99.95%. It has low false-positive and false-negative rates. These results demonstrate the effectiveness of ANN in predicting water quality status using sensor-based data. This suggests its potential for real-time monitoring and decision-making support in small-scale ornamental fish aquaculture.

Abstract

Background: Live feed is a critical factor in the successful rearing of African catfish (Clarias sp.) larvae, particularly during the early developmental. Tubificid worms (Tubifex sp.) are commonly used as live feed due to their high protein content; however, their nutritional value can be further improved through enrichment techniques.Aims: This study evaluated the effects of vitamin C-enriched Tubifex worms on the growth performance and survival of African catfish larvae.Methods: A completely randomized design (CRD) consisting of three treatments and three replications was employed: unenriched Tubifex worms (control), enrichment with 2.5 g L⁻¹ vitamin C (A), and enrichment with 3.5 g L⁻¹ vitamin C (B). Data on survival rate (SR), specific growth rate (SGR), and growth rate (GR) were analyzed using one-way analysis of variance (ANOVA), followed by Duncan's multiple range test at a 95% confidence level. Seven-day-old larvae were reared for seven days and fed enriched worms according to the respective treatments. Growth performance was assessed using survival rate (SR), specific growth rate (SGR), and growth rate (GR).Results: The results showed that vitamin C enrichment significantly affected (P < 0.05) the survival rate, specific growth rate, and growth rate of African catfish larvae. The treatment enriched with 2.5 g L⁻¹ vitamin C produced the highest survival rate (86.67 ± 12.09%), specific growth rate (1.70 ± 0.66% day⁻¹), and growth rate (0.125 ± 0.055 g day⁻¹). These values were significantly higher than those of the control treatment and numerically higher than those of the 3.5 g L⁻¹ treatment.Conclusion: In conclusion, enrichment of Tubifex worms with vitamin C at 2.5 g L⁻¹ is an effective strategy for improving growth performance and survival of African catfish larvae and may be applied as a practical nutritional approach during the early rearing stage.
