Abstract

Nannochloropsis oculata is a microalgae often used as natural food for fish larvae. In general, microalgae cultivation uses standardized Walne fertilizer. This research uses an experimental method to determine the effect of administering Azolla microphylla liquid fertilizer at different doses on the growth of the N. oculata population on a laboratory scale. This experiment was conducted from September to October 2022 at the Experimental Pond Laboratory, Biotechnology Laboratory, Marine Biology Laboratory, Department of Marine Science, Faculty of Fisheries and Marine, Universitas Riau. This research used a Simple, Completely Randomized Design (CRD) with four treatment levels and three replications. The treatment used A. microphylla liquid fertilizer with doses A (2 mL), B (3 mL), C (4 mL), and D (Walne fertilizer control). The results showed that the highest population density was in treatment D (control) on day 6 with a value of 483.5 x 105 (cells/mL) and treatment C (4 mL A.microphylla fertilizer) on day 5 with a value of 437.3 x 105 (cells/mL). The results of the ANOVA test showed a significance value of 0.007 < 0.05, which indicated a significant difference between the treatment of A. microphylla liquid organic fertilizer at different doses on the density of N.oculata. Relatively, the growth rate of N. oculata in treatment D (Walne fertilizer) was still the highest, with a value of 170.868%, and treatment C, with a percentage of 145.005%. Furthermore, the specific growth rate in treatment B was the highest, with a value of 1.730% on day 4. The Walne liquid fertilizer treatment, which was the control, was still higher and dominated the population and growth rate of N. oculata and could not be replaced with A. microphylla liquid fertilizer

Abstract

This research investigates the population dynamics of the gastropod Cerithidea obtusa along the eastern intertidal zones of Bengkalis Island, focusing on species abundance, spatial distribution, and size variation. Conducted over the span from December 2023 to January 2024, this investigation took place at two specific locales on the east coast of Bengkalis Island: Sekodi Village (Station I) and Teluk Lancar Village (Station II), employing a comprehensive survey methodology. The intertidal zones were segmented into upper, middle, and lower subzones, each with three transects containing one m² plot. Temperature, salinity, pH levels, substrate composition, and organic matter content were measured as indicators of the quality of the environment. The results revealed a significant difference in population density between the stations, with Station I showing the highest abundance at 240.000 ind/Ha and Station II the lowest at 33.300 ind/Ha. The middle subzone at Station I was the most populated, with 93.300 ind/ha. Shell size analysis revealed three categories: small (<3,35 mm), medium (3,35-4,05 mm), and large (≥4,05 mm), with medium-sized shells being the most prevalent. The distribution pattern of C. obtusa exhibited both uniform and clustered arrangements. A significant disparity in abundance was noted between Station I and Station II, with a p-value of 0,000, underscoring the considerable

Abstract

The population structure is a collection of organisms living in a particular area at a specific time and originating from the same species. The intertidal zone is between the sea's high and low tide lines, which have extreme ecological conditions. Several groups of organisms, including gastropods, can adapt to this environment. One type of gastropod that inhabits this area is Nerita articulata. This research was conducted in December 2023 in the intertidal zone of Teluk Lancar Village. The study aimed to analyze the population structure of N. articulata in the intertidal zone of Teluk Lancar Village, including population abundance, shell size frequency distribution, and distribution patterns. The research used a survey method. The intertidal zone is divided into three subzones: upper, middle, and lower. In each subzone, three quadrat plots measuring 1x1 m are placed. Environmental parameters measured include water quality, such as temperature, salinity, pH, substrate type, and organic matter. The research results indicate that the population abundance of this species varies, ranging from high to moderate to low. The highest abundance is found in the upper subzone, while the lowest is in the lower subzone. The shell sizes of this species are grouped into 3 size classes: <18.3 mm, 18.3-24.4 mm, and >24.4 mm. The largest and smallest shell sizes are commonly found in the upper subzone. The distribution pattern is uniform with a Morisita index value (Id < 1). The abundance of N. articulata among subzones differs significantly (p < 0,05), while the size among subzones does not differ significantly (p > 0,05).

Abstract

ABSTRACT Activities of phytoplankton culture needed to be supported by physical and chemical parameters. This study aimed to analyze the effect of a combination of salinity and Walne fertilizer on the population growth of Nannochloropsis sp on the laboratory scale. The method used in this study is an experimental method using CRD (Completely Randomized Design) experimental design with 2 factors, namely salinity and Walne fertilizer, and each factor is given 3 levels of treatment. The level value of each factor is combined to obtain 9 combinations with 3 replications to obtain a total of 27 experimental units. The results of measuring the water quality parameters show that the media conditions were in good condition: an average temperature of 21℃, an average pH of 7.6, and the LED light used is ±2,000 lux. The results showed no significant effect of the combination of salinity and Walne fertilizer on the population growth of Nannochloropsis sp. The best combination value was obtained in the S1W1 treatment with a combination of 15 ppt salinity and 0.5 mL Walne fertilizer dose, resulting in cell population density (4125x103 cells/mL). The second best was obtained in the S1W2 combination with 15 ppt salinity and 1 mL Walne fertilizer dose (3775x103 cells/mL).
