Abstract

The frigate tuna (Auxis thazard) is important to the fishing industry in West Sumatra. The increasing demand for frigate tuna causes this fish to continue to be exploited. Exploitation carried out continuously can reduce frigate tuna production, so research needs to be done. The research was conducted to: (1) Know the growth pattern and factor condition of frigate tuna (A. thazard) in West Sumatra waters; (2) Know the reproductive biology of frigate tuna (A. thazard). Samples were collected from fishermen's catch in the waters of West Sumatra. Random sampling was conducted, and samples were measured for length and weight, followed by dissection to ascertain sex ratio, gonadal maturity level, gonadal maturity index, and fecundity. The results indicated that the fish's length ranged from 350 to 475 mm, with an average of 401.48 mm, and their weight ranged from 408 to 1,339 grams, with an average of 755.8 grams. The growth pattern is identified as positive allometric (b>3), indicating that weight gain surpasses length increases. The condition factor is in stable condition with an average of 1.24. The sex ratio is in an unbalanced condition with a ratio of males and females of 0.9: 1. The level of gonad maturity obtained is GML III and GML IV. The gonad maturity index of male fish ranged from 1.71 to 3.04 and female fish from 1.28 to 2.50. Estimated fecundity ranged from 261,468 to 2,775,590 grains. Based on several factors included in this study, the reproductive biology of frigate tuna in the waters of West Sumatra is favorable.

Abstract

Diatom analysis is one of the most reliable indicators for confirming death due to drowning. Diatoms are microscopic algae that can enter the respiratory tract during water aspiration and provide ecological evidence linking the victim to the drowning site. This study aimed to analyze the presence of diatom species and taxonomic similarity between water samples and the internal organs of experimentally drowned white rats (Rattus norvegicus) to validate their use as a forensic model. Experimental drowning was performed using water of the Batang Arau River, West Sumatra in the February 2024 to January 2025. In this study, we were found 56 species of diatoms in the waters, while 31 were found in white rats' internal organs. The highest diversity found in the esophagus (31 species) and lungs (19 species). No diatoms were detected in the heart, liver, or kidneys. The distribution pattern, limited to the respiratory system, indicated early drowning aspiration with no systemic circulation. The typical species is a diatom species only found in water and in the internal organs of white rats in specific locations. Achnanthes adnata, Cocconeis pellucida, Cocconeis pseudomarginata, Eunotia bilunaris, and Gomphonema pumilum are typical species at Location I. Amphora bigibba and Amphora bioculata are typical species at Location IV. At the same time, Navicula viridula is the typical species at Location VI. These findings validate the white rat as an effective experimental model for drowning research and demonstrate that species-specific diatom fingerprints can aid forensic investigators in determining both the vitality of drowning and the probable crime scene.

Abstract

Heavy-metal contamination remains a critical ecological threat in tropical coastal ecosystems, particularly along the West Coast of Sumatra, where concentrations of Pb, Cd, and Cu frequently approach or exceed biological stress thresholds. This article evaluates marine microalgae as indicators of heavy metal pollution, combining global biomarker evidence with region-specific hydrodynamic conditions, referring referring to publications from the last six years. The findings reveal strong cross-study convergence in microalgal responses, including chlorophyll degradation, photosynthetic inhibition, oxidative stress, and antioxidant enzyme activation. These biomarker patterns align closely with local observations from Sumatra, indicating that microalgae operate within exposure ranges known to induce sublethal physiological impairment. Hydrodynamic modulation driven by monsoon cycles further amplifies metal bioavailability, producing alternating acute and chronic stress regimes that chemical monitoring alone often fails to detect. This review provides the first integrated assessment linking microalgal biomarker evidence with monsoon-regulated metal dynamics in Indonesian coastal waters. By synthesizing mechanistic, ecological, and environmental data, the study establishes a robust scientific foundation for adopting microalgae as a core component of early-warning systems and coastal biomonitoring frameworks. The findings also highlight methodological gaps and propose future directions to strengthen monitoring programs within a One Health perspective
