Abstract

This study analyzes fluctuating asymmetry (FA) in body shapes of pond-raised and wild type of Oreochromis niloticus to assess morphological variations. Using Procrustes ANOVA, significant differences were found in directional (p < 0.0001) and fluctuating asymmetry between populations. Principal Component Analysis (PCA) revealed that for male Tilapia, cumulative variation reached 74.15%, with PC1 contributing 29.04%. For females, the cumulative variation was 74.99%, with PC1 accounting for 24.97%. Key landmarks affected included the snout tip in males and several features in females, such as the dorsal fin insertion and eye margin. These landmarks indicate major morphological differences between the two populations. Geographic isolation, food availability, and environmental conditions likely contribute to the observed variations. The study highlights the effectiveness of fluctuating asymmetry analysis in characterizing body shape differences in Tilapia, emphasizing the need to consider environmental factors and stressors when interpreting these morphological variations, which may have implications for reproduction and development.

Abstract

This study aims to determine the antimicrobial activity of ethanol extract of matoa leaves (Pometia pinnata) against Salmonella typhi and Bacillus subtilis bacteria. This study began with preparing raw materials in the form of matoa leaves and then extracting the matoa leaves using the maceration method with 70% solvent. After that, the antimicrobial activity test was carried out using the disc diffusion method with four concentration variations, namely 5%, 7.5%, 10%, and 12.5% with a positive control in the form of 50 ppm amoxicillin and a negative control using distilled water, each treatment using three replications. The results in the form of inhibition zones formed were measured using calipers. The data obtained were then analyzed using SPSS 30 with the ANOVA test and further tests in the form of tests. The test results showed that 70% ethanol extract of matoa leaves had an effect on inhibiting the growth of Salmonella typhi and Bacillus subtilis bacteria. The largest inhibition zone in Salmonella typhi was found at a concentration of 7.5% with a diameter of 16.87 mm, while in Bacillus subtilis it was found at a concentration of 12.5% with a diameter of 12.22 mm.

Abstract

This research aims to determine the total phenolic content and antioxidant activity of the ethanol extract from Matoa (Pometia pinnata) leaves as well as its effect on blood sugar levels in male mice (Mus musculus) induced with alloxan. To determine total phenolic content using the Folin-Ciocalteu method, and the DPPH method to measure antioxidant activity. The effect of Matoa leaves on blood sugar reduction in mice used a completely randomized design (CRD) with 15 mice divided into 5 treatments with 3 replications: namely P1 (Extract 125 mg/kg BW), P2 (Extract 250 mg/kg BW), P3 (Extract 500 mg/kg BW), K+ (Glibenclamide), and K- (Na-CMC 0.5%). Extraction used the maceration method with 70% ethanol solvent. The results of the total phenolic test showed the presence of phenolics with a value of 26.24872 mg GAE/g. The measurement of antioxidant activity yielded an IC50 value of 1.961 ppm. The results of testing the blood sugar levels showed that there was an effect of giving ethanol extract of Matoa (Pometia pinnata) leaves on reducing blood sugar levels in male mice (Mus musculus). Giving of ethanol extract of Matoa leaves at a dose of 250 mg/kg BW is effective in reducing blood sugar levels. So it can be concluded that the ethanol extract of Matoa leaves has an effect on reducing blood sugar levels in male mice

Abstract

Pomacea canaliculata or Golden Apple Snail (GAS) existed to be a rice pest in the Philippines and Asia. Likewise, geographic location also contributes to its increasing populations, thus making it invasive among freshwater habitats and rice field areas. This study was conducted to describe shell shape variations and sexual dimorphism among the populations of P. canaliculata. A total of 120 samples were randomly collected in the downhill and uphill geographic locations in Mambajao, Camiguin Island, Mindanao, Philippines. To determine the variations and sexual dimorphism in the shell shape of golden apple snail, coordinates were administered to relative warp analysis and the resulting data were subjected to Multivariate Analysis of Variance (MANOVA), Principal Component Analysis (PCA) and Canonical Variate Analysis (CVA). The results show statistically significant (P < 0.01). While male and female spire height, body size, and shell shape opening also show significant variations. These phenotypic distinctions could be associated with geographic isolation, predation, and a nutrient component of the gastropods. Thus, the importance of using geometric morphometric advances in describing sexual dimorphism in the shell shape of P. canaliculata.

Abstract

This study investigates the potential of mango leaf extract as a natural preservative to extend the shelf life of milkfish (Chanos chanos) during storage. The extract was prepared using a standardized method and applied to milkfish fillets, followed by an analysis of its effects on microbial growth, sensory attributes, and overall shelf life. The milkfish samples were stored in the refrigerator, and periodic evaluations of sensory quality, including color, texture, odor, and taste, as well as microbiological parameters, were conducted. The findings of this study demonstrate that mango leaf extract effectively inhibits microbial growth and shows potential as a natural preservative for milkfish. The use of 1% mango leaf extract, especially ethanol-based, exhibited the highest microbial inhibition, significantly extending the shelf life and maintaining the quality of milkfish compared to untreated samples. These findings suggest that mango leaf extract can be an effective, natural alternative to chemical preservatives in extending the shelf life of milkfish, offering a promising solution for sustainable seafood preservation.

Abstract

The practice of eating fresh seaweed is needed to assess the microbiological aspects of the seaweed, as it may contain pathogens hazardous to human health. This study aimed to assess the bacterial load of the fresh edible seaweeds Caulerpa racemosa and Kappaphycus alvarezii that are collected from the wild and then sold to public markets. All seaweed samples collected from wild and public markets are examined for aerobic bacteria (Aerobic Plate Count), coliforms (Coliform Count), Salmonella, and E. coli. The results revealed that the coliform, Salmonella, and E. coli were absent in all samples. The aerobic bacteria from the Caulerpa racemosa and Kappaphycus alvarezii collected from the public market were within the limits of the food quality standards set by JECFA, FDA-Philippines, and Food standards of Australia and New Zealand. As for Kappaphycus alvarezii collected from the wild revealed a higher Aerobic Plate count and has exceeded the limits on the food quality standard set by the agencies stated. This study concludes that Caulerpa racemosa and Kappaphycus alvarezii from the public market conform to the requirements of the food quality standards and that sanitary handling of edible seaweeds sold to public markets was properly practiced.
