Abstract

Tor tambroides (Cyprinidae), or gadih fish, was an endemic fish that inhabited the upstream of the Kampar Kanan River. The population and habitat of this fish have been reduced. As the fish's life quality is reflected in the growth pattern in the otolith, the cause of this fish's decline may be investigated through its growth ring pattern in the otolith. A study aimed to comprehend the pattern of otolith growth rings was conducted from August to October 2023. The fish were gathered from fishermen who caught them in the river area that crosses Bandur Picak Village. A total of 31 fish were captured during the study. The otoliths were then removed, processed, and investigated under a binocular microscope. Results showed that the size of fish captured ranged from 77-1521 g BW and 194-505 mm TL, while the otolith size was 2-5 mm in length and 0,0028-0,0148 g in weight. In all fishes captured, the number of dark rings in the otolith was only 1-2 rings, and the distance between the nucleus and the first dark ring ranged from 0.5 to 1 mm.  There was no special pattern at those distances, indicating that the dark growth rings were not caused by periodic incidents, but were formed individually. Based on the number and the pattern of the otolith’s growth rings, it can be concluded that the life quality of the fish was relatively good and that it rarely faced problems that hamper their growth, as reflected in the otolith growth ring pattern.

Abstract

The culture of giant freshwater prawn (Macrobrachium rosenbergii) has promising economic prospects; however, it faces constraints in reproduction, particularly the slow process of gonadal maturation, which depends on seasonal factors. This dependency results in limited availability of mature broodstock throughout the year. The objective of this study was to evaluate the effects of dietary supplementation with probiotics, wheat, and sesame seeds on the reproductive performance of giant freshwater prawn. The research was conducted at Djuanda University, Bogor, West Java. The experiment was carried out from July to September 2024. The experimental design consisted of four treatments with four replications over a 70-day period: P1 (control), P2 (feed + probiotic), P3 (feed + probiotic + wheat), and P4 (feed + probiotic + sesame seeds). The observed parameters included body weight, body length, cephalothorax circumference, gonadal maturation stage (GMS), and gonadosomatic index (GSI). The results showed that treatment P4 produced a significant increase in all parameters, with a final body weight of 20±0.92 g, body length of 18.45±0.95 cm, cephalothorax circumference of 8.14±0.84 cm, and the highest GSI of 2.33%. The highest gonadal maturation stage (GMS IV) was also achieved more rapidly in P4 compared to other treatments. These findings indicate that the combination of probiotics and sesame seeds is effective in accelerating gonadal maturation and enhancing reproductive performance. Therefore, the use of natural additives such as probiotics and sesame seeds has potential as an alternative technology to improve the productivity of giant freshwater prawn culture.

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.
