Abstract
The Celebes Sea provides critical foraging and
migratory habitats for sea turtles in Malaysian waters, yet health status data,
including hematologic and blood biochemistry parameters, remain scarce. To
address this gap, we examined the blood profiles of green turtles and hawksbill
turtles in these foraging grounds. Physical assessments such as body condition
scores and indices suggested overall clinical health, though one green turtle
exhibited

Abstrak
Laut Sulawesi merupakan habitat penting untuk pemakanan dan migrasi penyu di perairan Malaysia, namun data
status kesihatan, termasuk parameter hematologi dan biokimia darah, masih kurang. Untuk menangani jurang ini, kami mengkaji profil darah penyu hijau dan penyu karah di kawasan pemakanan ini. Penilaian fizikal seperti skor dan indeks keadaan badan menunjukkan kesihatan klinikal secara keseluruhan, walaupun terdapat seekor penyu hijau yang menunjukkan fibropapillomatosis, serta penemuan baharu teritip pengorek Chelolepas cheloniae pada karapas. Sampel darah daripada 32 penyu hijau dan 4 penyu karah dianalisis menggunakan penganalisis darah genggam iSTAT yang mendedahkan perbezaan antara spesies dalam nilai darah. Penyu karah menunjukkan kepekatan nitrogen
urea dalam darah yang lebih tinggi, kemungkinan disebabkan oleh diet protein yang tinggi, manakala seekor penyu hijau menunjukkan profil darah tidak normal yang menunjukkan kemungkinan asidosis. Kajian ini menyediakan data asas kesihatan untuk penyu di kawasan pemakanan di Laut Sulawesi, menekankan kepentingan pemantauan hematologi dan biokimia dalam menilai status kesihatan serta membentuk strategi pemuliharaan yang disasarkan untuk menangani ancaman di habitat pemakanan mereka. Penemuan ini membantu kita memahami kesihatan penyu dengan lebih baik dan menyokong usaha melindungi spesies penting ini dan habitat mereka.
