Abstract

This study aims to determine the growth and survival of kissing gourami (Helostoma temminckii) on a rearing medium given liquid biological fertilizer. This research was conducted from 01 April to 21 May 2022 at the Hatchery, Faculty of Fisheries and Marine, Universitas Riau. The container used was a bucket with a volume of 100 L. This study used a one-factor, Completely Randomized Design (CRD) method with five treatments and three replications. The level of treatment applied in this study was P0 = No treatment, P1 = treatment of 0.01 mL/L water, P2 = treatment of 0.03 mL/L water, P3 = treatment of 0.05 mL/L water and P4 = treatment of 0.07 mL/L. The results showed that applying liquid biological fertilizer with different doses significantly affected fish growth performance (P<0.05). The best treatment was found at a dose of 0.03 mL/L, which produced a range of ammonia (0.0043-0.0163 mg/L), nitrate (0.049-0.189 mg/L) phosphate (0.036-0.072 mg/L), absolute weight growth (10.07 g), absolute length growth (11.31 cm), specific growth rate (1.94%), feed conversion (1.08%) and survival (85, 00%).

Abstract

This study aims to determine the effect of combining blood clam shell (Anadara granosa) filter media on water quality in the recirculation system for Asian Redtail catfish (Hemibagrus nemurus) maintenance. The study was conducted from December 2025 to February 2026 at the Cultivation Technology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau, using a Completely Randomized Design (CRD) experimental method with four treatments and three replications. The treatments consisted of P0 (control without blood clam shell), P1 (150 g/25 L of water), P2 (200 g/25 L of water), and P3 (250 g/25 L of water). The results showed that the use of blood clam shells as a filter medium was able to maintain water quality during cultivation, with a temperature range of 24–28.6°C, pH 2.16–7.94, DO 4.96–6.47 mg/L, TDS 22–1038 mg/L, ammonia 0.015–1.429 mg/L, and nitrate 0.0604–21.2729 mg/L. The best treatment was obtained at P3, with a final fish length of 16.8 cm, SGR of 3.60%, feed efficiency of 93.45%, and the lowest FCR of 1.07. The fish survival rate ranged from 87–96%.

Abstract

Sand lobster (Panulirus homarus) is a high-value marine commodity with promising potential for mariculture development in Indonesia. This study described the grow-out technique for P. homarus in floating net cages at BPBL Batam. It evaluated its production performance in terms of growth, feed utilization, survival, and water quality. A field-based observational study was conducted for 74 days using juveniles with an initial mean body weight of 5.14 g and an initial mean total length of 5.44 cm. Lobsters were reared in six submerged M-sized cages (0.7 m² per unit) at a stocking density of 50 individuals per cage and were fed chopped trash fish once daily at 20% of biomass. Mean body weight and total length increased to 20.94 g and 8.47 cm, respectively, with absolute weight gain of 15.80 g, absolute length gain of 3.03 cm, and a specific growth rate of 1.89% day⁻¹. However, the feed conversion ratio was high (30.00), and the survival rate was low (40.33%). Water-quality variables remained within acceptable ranges for lobster culture. These findings indicate that the system supported lobster growth, but feed-use efficiency and survival still require improvement through better feeding and husbandry management.
