Comparative observation of the organ development and health of the tropical oyster Crassostrea belcheri (Sowerby, 1871) in hatchery and wild farming sites
--------
The tropical oyster, Crassostrea belcheri, is an important, high-value seafood in aquaculture in Thailand. Understanding the development and physiological responses of C. belcheri in different rearing conditions is essential for sustainable production. This study compared the histological structures, mucus-secreting cell (MSC) distributions, and gonadal development of C. belcheri sampled from a hatchery (HAT) and three open-sea farming sites. The sampled oysters were classified into five categories based on shell height: 1.0–2.5 cm, 2.6–4.1 cm, 4.2–5.7 cm, 5.8–7.3 cm, and 7.4–8.8 cm. Size- and site-dependent differences in organ morphology were observed. In the largest HAT oysters, the average gill lamella length was 128.8 ± 7.3 µm; average mantle epithelium thickness 14.1 ± 1.0 µm and average digestive tubule diameter 86.5 ± 2.2 µm. All three morphometrics differed significantly across the four sites (p < 0.05). Four MSC morphotypes were observed. Gonadal development followed a protandric pattern, with male gametogenesis observed in oysters smaller than 5.8 cm and female oogenesis being dominant in larger individuals (> 5.8 cm). Oocyte maturation across sites was consistent rather than site dependent. Histopathological evaluation using the Health Assessment Index (HAI) revealed sublethal tissue alterations, including epithelial atrophy, digestive tubule regression and gill lamellar fusion, with a mean HAI score of 3.7 ± 1.2 for wild-farmed oysters compared with 1.8 ± 0.9 for HAT samples. These findings underscore strong associations between oyster size, environmental conditions and organ development, and the potential of MSC density and histopathological lesions as reliable biomarkers for aquaculture monitoring and health management in C. belcheri

Biometrical, anatomical, and histological characterization of the Thai female dugong (Dugong dugon) reproductive system: Estimating sexual maturity and conservation applications
--------------------------------------------------------

A recent study reveals important details about the reproductive biology of Thai female dugongs (Dugong dugon)—a vulnerable marine mammal in Southeast Asia. By examining body measurements, reproductive anatomy, and tissue histology from five stranded dugongs, researchers identified reliable indicators of sexual maturity that go beyond body size alone.

The study found that ovarian structures, such as corpora lutea and placental scars, are key markers of reproductive maturity, while body length alone can be misleading. Mature dugongs also showed wider vaginal and vestibular structures, and evidence suggested that Thai dugongs may mature over a broader size range than populations in Australia.

✨These findings provide the first reproductive baseline for Thai dugongs, offering practical tools for field assessments and supporting evidence-based conservation planning to better protect this endangered species.

📢 New Research Alert: Parasites Found in Thai Dugongs! 🐋🌊

A new study has revealed the first confirmed cases of the respiratory parasite Pulmonicola cochleotrema in dugongs from Thailand’s Andaman Sea.

Out of 166 stranded dugongs examined, 6% were infected, with parasites found from the nostrils down to the lungs.
The research combined morphology, molecular genetics, and pathology, showing that this parasite can cause severe airway inflammation and pneumonia, which may contribute to dugong deaths.

This is the first comprehensive report in Thailand, providing essential baseline data to support dugong health monitoring and conservation.

This review highlights the critical decline of dugongs (Dugong dugon) in Thailand, driven by habitat loss, bycatch, and environmental changes. Once abundant, the population has dropped to around 240 individuals by 2024, with strandings sharply increasing. The Gulf of Thailand now supports only about 18 dugongs, while the Andaman Sea population faces ongoing threats from seagrass degradation. Evidence of migration to new areas, such as Phuket, reflects habitat stress. Although community-based conservation and marine protected areas offer hope, the species’ survival in Thailand remains fragile, requiring urgent, coordinated efforts to restore habitats and reduce human impacts.

Bacterial infections and antibiotic resistance in stranded dugongs (Dugong dugon) from the Andaman Sea, Thailand

-----
This study provides the first comprehensive insight into bacterial pathogens and antibiotic resistance in dugongs from Thai waters. It identified Vibrio spp. and Photobacterium damselae as the predominant bacteria associated with septicemia, along with evidence of diverse antibiotic resistance genes—including blaCTX-M, blaOXA-1, and tetM—in most isolates. The detection of resistance genes even in phenotypically susceptible bacteria suggests the presence of hidden resistance reservoirs in the marine environment. These results establish crucial baseline data for Thailand, highlight the emerging issue of antimicrobial resistance in marine wildlife, and support the development of better treatment protocols and monitoring strategies for stranded marine mammals.
