Abstract

This study aimed to determine the optimal salinity in increasing the growth rate of Chlorella sp in laboratory scale culture. This research was conducted in July 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The experimental method was applied using a complete randomized design (CRD) with four treatments and three replicates. The treatments were as follows: T0 (control), T1 (25 ppt salinity), T2 (30 ppt salinity), and T3 (35 ppt salinity). The initial density of Chlorella sp was 250x103 cells/mL, and cell abundance observations were carried out for 14 days. The parameters observed were cell abundance, specific growth rate, and water quality (temperature and pH). The results showed that different salinity influenced the growth of Chlorella sp. 35 ppt salinity gave the best results on cell abundance of 266.66x104 cells/mL, with peak population occurring on day 10. Water quality during the study was still in the normal range and can be tolerated for the growth of Chlorella sp, and the temperature ranged from 25-31oC and pH 6.4-8.0

Abstract

Chlorella sp. is a microalga that can grow and develop in wastewater media, including sago liquid waste that is not utilized and becomes a pollution material. This study aims to determine the utilization of sago liquid waste organic fertilizer on the growth of Chlorella sp. This research was conducted in February 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Riau University. The method used was the experimental method, by applying a complete randomized design (CRD) with four treatments and three replicates. The treatments were as follows: T0 (control), T1 (150 ml sago liquid waste), T2 (200 ml), and T3 (250 ml). The initial density of Chlorella sp. was 250 x103 cells/ml, and cell abundance observations were made for 14 days. The parameters observed were cell abundance, specific growth rate, and water quality (temperature and pH). The results showed that the utilization of sago liquid waste affected the abundance of Chlorella sp. 150 ml concentration and gave the best results on cell abundance of 233.33 x103 cells/ml with the peak population occurring on day 9. Water quality during the study was still in the normal range and can be tolerated for the growth of Chlorella sp, namely temperature ranging from 26-31o C and pH 6.2-8.0

Abstract

Moringa leaves can be used as an herbal plant in fish growth to prevent and treat bacterial infections. This study aims to determine the effect of fermented moringa leaves through feed on blood glucose in striped catfish (Pangasianodon hypophthalmus). This research was conducted from September to November 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Riau University. The method used is an experimental method using a completely randomized design with 4 (four) treatments and 3 (three) replicates; the treatment dose of fermented moringa leaves is T0 (control), T1 (10 g/kg feed), T2 (15 g/kg feed), and P3 (20 g/kg feed). The catfish measured 5.00 ± 1.00 cm and weighed 4.00 ± 0.50 g, reared in an 80 L tank at a stocking density of 1 fish / 4 L water. The maintenance was carried out for 60 days, and blood glucose observations were made at the beginning (H-1), day 30 (H-30), day 60 (H-60), and post-challenge test (H-75). The results showed that adding fermented moringa leaves to the diet did not affect the blood glucose of the catfish (p>0.05). This indicates that moringa leaves can keep the fish in normal condition after being challenged with Aeromonas hydrophila bacteria
