Description Title (Bahasa Indonesia): Histopatologi daging dan hati ikan kakap putih (Lates calcarifer) pada musim berbeda dari Perairan Teluk Kao yang tercemar merkuri (Hg), Halmahera Utara, Indonesia. Fish caught in Kao Gulf waters has been contaminated by mercury in low concentration. This study aimed to identify and analyze the impact of mercury (Hg). Water, sediment and fish samples were taken using a plastic scoop, a grab, and fishing. Hg content analysis used AAS (atomic absorption spectrophotometer). While the histopathological analysis of the fish meat and liver used automated slide stainer and microscope. Hg concentration of Kobok and Taolas river water in dry season and rainy season was not safe to consume according to Indonesian National Standard of 7387/2009 for natural mineral water. Hg concentration of the sediment also did not meet the Indonesian quality standard according to Government Regulation Numbered 82/2001. Fish were still allowed to be consumed. The meat and liver histopathology  in dry and rainy season had tissue cell change, such as edema, degeneration hydrophic, and lamellae fusion. Ikan yang tertangkap di Perairan Teluk Kao telah terkontaminasi dengan merkuri dalam jumlah rendah. Penelitian ini bertujuan untuk mengetahui dan menganalisis dampak pencemaran merkuri (Hg) dengan menginformasikan keamanan konsumsi ikan Kakap Putih di perairan Teluk Kao Halmahera Utara.  Sampel air diambil mengunakan gayung plastik, sampel sedimen dengan alat grab sampler sedangkan sampel ikan mengunakan alat pacing. Analisis kandungan Hg air, sedimen dan ikan dengan metode AAS (atomic absorption spectrophotometer). Analisis histopatologi daging dan hati ikan dengan alat automated slide stainer dan mikroskop. Hasil menunjukkan bahwa Nilai Hg air sungai Kobok dan Taolas pada musim panas dan musim hujan tidak layak dikonsumsi menurut SNI 7387/2009. Konsentrasi Hg dalam sedimen juga tidak memenuhi Standar Baku Mutu Indonesia menurut Peraturan Pemerintah No. 82 Tahun 2001.  Ikan kakap putih masih diizinkan untuk dikonsumsi. Histopatologi daging dan hati ikan kakap putih pada musim panas dan musim hujan yang mengalami perubahan jaringan sel, seperti mengalami edema, degenerasi hidropis, dan fusi lamellae.
