Abstract

Brine shrimp (Artemia salina) cytotoxicity assays (BSLT) are one of the commonly used cytotoxic test methods to assess a plant extract's pharmacological activity and toxicity. Thus, this study aimed to examine the toxic levels of Kecubung (Datura metel) leaves extracted using different solvents, namely ethanol and ethyl acetate. The results showed that the LC50value of flower ethanol, flower ethyl acetate, leaf ethanol, and stem ethyl acetate extracts had an LC50value 1000, which was included in the toxic category. The LC50value of flower ethanol is 121.044 ppm, flower ethyl acetate 105.89 ppm, leaf ethanol 639.589 ppm, and stem ethyl acetate 635.276 ppm. Ethanol leaf extract at a concentration of 1000 ppm showed the highest mortality with a percentage of 60% of the total number ofA. salina. The flower ethanol extract showed the highest mortality at a concentration of 250 ppm with a percentage of 67% and at a concentration of 1000 ppm with a percentage of 70% of the total number ofA. salina. Meanwhile, flower ethyl acetate and stem ethyl acetate extract at a concentration of 1000 ppm obtained 100% mortality ofA. salinain the first 6 hours. The result shows that the flower ethyl acetate and stem ethyl acetate extract at a concentration of 1000 ppm is very toxic compared to other concentrations.Keywords:ToxicityArtemia salinaLC50Ethyl acetateEthanol

Abstract

This study was conducted to determine the effect of water salinity changes on methionine content in tiger grouper juvenile (Epinephelus fuscoguttatus). A total of 2,560 tiger grouper juveniles were used and divided into five groups consist of 1 control group (without exposed to salinity changes) and 4 treatment groups. The salinity was changed every 2, 3, 4, and 6 hours in treatment A, B, C, and D, respectively. Salinity levels were changed during 24 hours by lowering salinity level from 32 psu to 22 psu. Twenty five of fish were collected from each treatment for methionine content analysis. Data were analysed using one way analysis of variance (ANOVA). The results showed that there was a decrease in methionine content in all treatments. A significant decrease (P0.05) of methionine content in treatment A, B, and C were observed after 20 hours (1.15%), 18 hours (1.27%), and 16 hours (1.24%), respectively. While at 0 hours (control), the methionine content was 2.02%. Methionine level in treatment D was not significantly different (P0.05) compared to control group. As conclusion, rearing the tiger grouper juvenile with salinity fluctuations every 6 hours did not lead to methionine deficiency.

Abstract

The threat of decreasing populations of Tor species continues to increase due to intensive fishing, habitat destruction and infrequent cultivation efforts. Monitoring of this group of fish must be carried out routinely to reveal the population conditions of fish. This research aims to reveal the population conditions of fish through an analytical approach to the length-weight relationship and fish otolith size. All fish samples were then taken for otoliths to measure their size and analyzed further using a scanning electron microscope (SEM). The research was conducted in the Tangkahan River, North Sumatra, Indonesia from January-March, 2023. The results showed that 43 samples of T. douronensis, 34 samples of T. tambra, and 24 samples of T. tambroides had b values of 2.853, 2.757, and 2.353, respectively. The b value in this study indicated that the fish had a negative allometric growth pattern. The size of the otoliths of the three Tor species shows that T. tambra has the highest length (the distance measured from the anterior to the posterior of the of sagitta otolith) on average reaching 9.31 mm, while T. tambroides and T. douronensis only reach 1.53 mm and 1.83 mm. The results were confirmed by ANOVA showing significant differences (P 0.05) in the mean value of otolith size based on Tor species, where the otolith size of T. tambra was significantly different compared to the other two species. The condition of Tor species in the Tangkahan River has experienced ecological pressure. This indication was concluded from the results of the analysis of the length-weight relationship of fish which showed b value 3 (negative allometric). The results show that the characteristics and size of the otoliths can differentiate Tor species and facilitate identification efforts related to management and conservation.Keywords:Habitat DestructionNegative AllometricAnterior of Sagitta OtolithPosterior of Sagitta Otolith

Abstract

It is necessary to collect data on the species of fish that live in a body of water, one of which is by carrying out an inventory of fish species. The method used is purposive sampling in places that are thought to have lots of fish, are easy to reach and represent the river area. The research parameters in this activity are the level of diversity, level of uniformity, level of dominance, level of species richness, level of similarity, distribution pattern, relationship between length and weight and condition factors. The aim of this research is to provide real benefits in an effort to find out the potential of what species of fish are found in the Leuser Ecosystem, especially the Celike River. There are 13 species of fish found in the Celike River in the Leuser Conservation Area, East Aceh, belonging to 7 families with a total of 132 individuals. The diversity index value is classified as moderate with a value for station 1 of 1.26 and station 4 of 1.49. The highest uniformity index is at station 5 and station 3. The uniformity index value at these stations has the same index (E = stable 0.91). Stations 2, 3, 4, 5 and station 6 have the highest dominance index values in the high category (C=0.87-1.18).Keywords:IchtiofaunaCelike RiverLeuser EcosystemExploration

Abstract

White shrimp (Litopenaeus vannamei) cultivation activities have developed rapidly in Indonesia. White shrimp aquaculture which is carried out intensively with high stocking densities has caused several problems, such as low survival and suboptimal growth. This study aimed to increase the growth, feed conversion, and survival of white shrimp through a combination of probiotics (Lactobacillus sp.) + turmeric flour (Curcuma longa) in feed. The method used in this study was Completely Randomized Design (CRD) with four treatment levels and three replications. The results revealed a significant effect (P0.05) on the value of the daily growth rate (DGR), absolute growth rate (AGR), specific growth rate (SGR), survival rate (SR), feed conversion ratio (FCR), and feed efficiency (FE), but no significant effect (P0.05) on the value of the absolute length rate (ALR). Giving probiotics 10 ml+5 g turmeric flour/kg feed (treatment B) was the best treatment for white shrimp aquaculture, including DGR, AGR, ALR, LPS, SR, FCR, and FE values. Furthermore, the results also revealed that increasing the concentration of turmeric flour in the feed, was negatively correlated to the growth and survival of white shrimp.

Abstract

Violet Batissa (Batissa violacea) is an important economic organism on the west-south coast of Aceh, because it is relatively high consumed by the community. However, gold mining activities carried out around the watershed are estimated to pollute the river and cause B. violacea to also be affected. The purpose of this study was to determine the level of mercury (Hg) and Lead (Pb) contamination in clam meat in Teunom, Aceh Jaya Regency. The research was conducted from June to September 2021. Sampling of clam was done by purposive sampling method. Hg and Pb were analyzed in clam meat using the Atomic Absorption Spectrophotometer (AAS) method. The results of the analysis showed that the Hg content in clam meat was between 0.12-0.63 mg/kg (mean 0.350.26 mg/kg), water 0.0026-0.0103 mg/kg (mean 0.00520.004 mg/kg), and sediment 1.3224-3.8767 mg/kg (mean 2.23241.427 mg/kg). Furthermore, the results of the analysis showed that the Pb content in clam meat, water and sediment had the same value at 3 stations with values 0.00020 mg/kg, 0.00030 mg/kg, and 0.00020 mg/kg, respectively. The conclusion of this study is that the Hg content in water and sediment has exceeded the threshold, while the clam meat is still in good quality standards. The Pb content in clam meat, water and sediment were also in good quality standards. Based on our study, B. violacea is still safe for consumption, while the water has been polluted and is recommended not to be utilized for human consumption.Keywords:Heavy metalRiverWaterSedimentBatissa violacea
