Abstract

Cyprinus rubrofuscus has high economic value as a freshwater ornamental fish, in demand in the international market. The growth of koi fish can be increased by adding probiotics to the feed. This addition can benefit fish health and water quality if given in the correct dose. This study was conducted to see the effect of different doses of probiotics in the feed on koi growth. The study was conducted from February 2023 to February 2024, with treatments administered from May 28 to July 7, 2023. The design was a Completely Randomized Design (CRD) of four treatments (PB0, PB10, PB15, PB20) with three replications. The parameters measured included growth in length, weight, specific growth rate, and survival. At the end of the study, it was found that adding probiotic doses had a significant effect (P < 0.05) on weight, length, and specific growth rate, but did not affect survival. The PB15 dose gave the best results, with a weight gain of 0.46 ± 0.66 g and a particular growth rate of 1.88 ± 0.11% per day.

Abstract

Although Tengadak fish farming is not yet popular and its quantity and productivity are relatively low, it has the potential to be developed in Indonesia. The biggest challenge is the long spawning stage, so reproductive manipulation with synthetic hormones is necessary. This study aims to determine the optimal dose of purwoceng extract (Pimpinella alpina Molk.) in feed to improve the reproductive performance of barbel fish (Barbonymus schwanenfeldii). This research project was conducted at the Aquatic Laboratory of the Faculty of Agriculture at Djuanda University in Bogor from November 2023 to February 2024. A completely randomized design (CRD) with four treatments and three replicates was used, and the data were analyzed using ANOVA. The treatments included: P1 (control, no purwoceng extract); P2 (5 g purwoceng extract per kg of feed); P3 (10 g purwoceng extract per kg of feed); and P4 (15 g purwoceng extract per kg of feed). Four female tengadak fish with an average weight of 156 g and a length of 21 cm were used for each treatment. Results showed that administering purwoceng extract at a dose of 15 g/kg of feed resulted in an absolute weight growth of 18.23 ± 0.33 grams and the highest fecundity of 36,005 eggs. There was no significant difference in absolute length growth among the treatments. Proximate analysis of the gonads revealed an average protein content of 10.78%, fat content of 23.8%, moisture content of 75.6%, and ash content of 1.4%. Based on the research results, purwoceng extract can improve the reproductive performance of tengadak fish.

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

Abstract This study aimed to evaluate the growth and survival of freshwater lobster (Cherax quadricarinatus) in an aquaponic system integrated with water spinach (Ipomoea aquatica) based on phytoremediation technology. Focused on three treatments: CT (control without water spinach), WS5 (5 water spinach plants), and WS10 (10 water spinach plants). WS5 treatment provided the highest lobster survival rate at 95.8%, compared to the control and WS10 treatments, which were lower. The absolute growth in carapace length, weight, and specific growth rate of the lobster was also better in WS5 compared to the control and WS10. Statistically significant differences (p<0.05) were found in total absolute length growth and daily total length specific growth rate, with WS5 as the most effective treatment. Water quality measurements during the study showed that temperatures across all treatments were within the optimal range for freshwater lobster and water spinach cultivation, between 24.15–28°C. pH values and dissolved oxygen (DO) levels also remained within safe limits. The pH range in the CT and WS5 treatments was relatively wide, indicating active biological processes in the system. Overall, integrating five water spinach plants in the aquaponic system was proven to be the most effective in improving lobster growth performance and maintaining the quality of the cultivation environment. Additionally, the system demonstrated phytoremediation efficiency of water spinach biomass without the need for additional nutrient inputs. This study recommends the use of WS5 as the optimal model for the development of freshwater lobster aquaponics in the future.
