USE OF INORGANIC FERTILIZERS AND EFFECTS OF N:P RATIO MANIPULATION ON GROWTH OF THE CELL POPULATION OF Dunaliella sp.
Journal ID : ALS-08-08-2021-5601; Total View : 926; Author : Huynh Thanh Toi, Nguyen Thi Hong Van, Nguyen Van Hoa,
Abstract :

The aim of this study was to determine the appropriate dosage of NPK fertilizer (16-16-8) for the growth of Dunaliella sp. Two separate experiments were conducted in a controlled temperature (24 ± 2.0 °C) room. Microalgae were inoculated in 8 L jars at 25‰, and initial cell density was inoculated at 1 × 106 cells/mL. In the first experiment, NPK (N:P ratio of 1:1) was added to microalgae culture medium, with N concentrations of 8, 16, and 24 mg/L. The results showed that the highest cell density was obtained with 4.7 × 106 cells/mL on day 11 with the 16 mg/L treatment. In the second study, microalgae were cultured with different ratios of N:P—from 1:1 to 15:1—in which the final N concentration in the culture medium was 16 mg/L. The results showed that the cell density was highest at 5.72 × 106 cells/mL in the N:P treatment ratio of 9:1 on day 9, and the dry weight of biomass reached 0.15 g/L on day 7. Overall, the results of this study indicated that NPK can be used to culture Dunaliella sp., but it is necessary to adjust the N:P ratio to 9:1 in order to obtain the highest growth of the cell population

Study on the reproductive characteristics of Coilia rebentischii Bleeker, 1858 distributed at the estuary of the Hau River
Journal ID : ALS-08-08-2021-5600; Total View : 905; Author : Vo Thanh Toan, Truong Thanh Dinh, Tran Dac Dinh, Huynh Thanh Toi,
Abstract :

This study aims to observe the reproductive biology of Coilia rebentischii distributed from downstream of the Hau River (one of the branches of the Mekong River) to the estuary of Dinh an and Tran De, in order to supplement the existing scientific data and to serve as a basis for research on artificial reproduction. The study was conducted from July 2019 to June 2020 by collecting fish samples in three sites from downstream of the Hau River and the estuary of Dinh an and Tran De. Results showed that the gonadosomatic index (GSI) of C. rebentischii ranged from 1.10% to 6.92%, which was greater than the fluctuation in the hepatosomatic index (HSI) (from 0.21% to 1.20%); the conditional factor (CF) of the fish also displayed less fluctuation, with the CF reaching its highest value in November. Fecundity of fish ranged from 218–943 eggs/g (mean=495 eggs/g), with a total length of 10.4 cm and total weight of 16.01 g. The maturity size of female C. rebentischii was 11.05 cm, while that of males was 13.69 cm. Result was recorded that breeding season of C. rebentischii starts from January to December, in which the highest breeding is from June to November
