Ikan depik (rasbora tawarensis) merupakan ikan endemik di danau laut tawar, kabupaten aceh tengah. ikan ini merupakan salah satu ikan ekonomis penting karena banyak dikonsumsi oleh masyarakat. permintaan ikan depik yang tinggi mengakibatkan peningkatan usaha penangkapan ikan ini di alam. penelitian ini bertujuan untuk menganalisis pola pertumbuhan, faktor kondisi dan aspek biologi reproduksi ikan depik (r. tawarensis) di danau laut tawar, meliputi rasio kelamin, tingkat kematangan gonad (tkg), indeks kematangan gonad (ikg), ukuran pertama kali matang gonad, distribusi diameter telur, serta fekunditas. penelitian dilakukan mulai dari bulan oktober 2021 sampai april 2022 di danau laut tawar kabupaten aceh tengah. analisis terhadap ikan depik (r. tawarensis) dilakukan di laboratorium kesehatan ikan, dan lingkungan, bbi lukup badak, dinas perikanan kabupaten aceh tengah, dan pengamatan sampel telur dilakukan di laboratorium genetik, dan biodiversitas akuatik, fakultas kelautan dan perikanan, universitas syiah kuala. pengambilan ikan depik dilakukan dengan metode pengamatan sampel acak sederhana pada hasil tangkapan bagan lampu (cangkul padang). pengambilan ikan depik dilakukan di tiga stasiun selama enam kali ulangan pengambilan. hasil penelitian menunjukkan bahwa pola pertumbuhan ikan depik (r. tawarensis) bersifat allometrik negatif (b

Depik fish (Rasbora tawarensis) is an endemic fish in Lake Laut Tawar, Central Aceh Regency. This fish is one of the important economical fish because it is widely consumed by the community. The high demand for depik fish has resulted in an increase in this fishing business in nature. This study aims to analyze growth patterns, condition factors and aspects of reproductive biology of depic fish (R. tawarensis) in Fresh Sea Lakes, including sex ratio, gonadal maturity (TKG), gonadal maturity index (IKG), first-time size of mature gonads, distribution of egg diameters, and fecundity. The study was conducted from October 2021 to April 2022 in Fresh Sea Lake, Central Aceh Regency. Analysis of depik fish (R. tawarensis) was carried out at the Fish Health and Environment Laboratory, BBI Lukup Badak, Fisheries Service of Central Aceh Regency, and observation of egg samples was carried out at the Genetics and Aquatic Biodiversity Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University. The collection of depik fish was carried out at three stations during the six-time retrieval test. The results showed that the growth pattern of depik fish (R. tawarensis) was allometric negative (b
