Hubungan panjang-berat dan faktor kondisi sangat penting dalam studi penilaian perikanan, karena memberikan informasi tentang pertumbuhan ikan, kesejahteraan secara umum, dan kesehatannya. penelitian ini dilakukan untuk mengetahui hubungan panjang-berat dan faktor kondisi ikan kuwe (caranx ignobilis). ikan ini merupakan salah satu jenis ikan yang mempunyai nilai ekonomis di perairan tanjung buka, bulungan. sampel ikan diambil dari hasil tangkapan nelayan yang menggunakan kelong (guiding barrier). pengambilan sampel dilakukan pada bulan mei – juli 2023. spesimen yang diperiksa sebanyak 130 ekor, 102 ekor jantan dan 28 ekor betina. hubungan panjang-berat dianalisis menggunakan persamaan w = a.lb. faktor kondisi jenis ikan ditentukan dengan menggunakan persamaan fk = w/alb. hubungan panjang-berat menunjukkan pertumbuhan alometrik negatif, baik ikan jantan (b = 2,78) maupun ikan betina (b = 2,85). faktor kondisi berfluktuasi antara 0,72 dan 1,27 dengan rata-rata 1,003 yang menunjukkan bahwa ikan ini dalam keadaan sejahtera di lingkungannya. kata kunci: hubungan panjang-berat, faktor kondisi caranx ignobilis

Length-weight relationships (lwr) and condition factor are of great importance in fishery assessment studies since it provides information about the growth of the fish, its general wellbeing, and fitness in a marine habitat. this study was conducted to examine lwr and the condition factor of giant trevally (caranx ignobilis). this fish is one of the economically valuable fish in the tanjung buka waters. a fish samples were taken from guiding barrier. sampling was conducted in may – july 2023. 130 specimens examined, 102 were males and 28 were females. length- weight relationship was analysed using the equation w = a.lb. the condition factor of the fish species was determined using the equation, cf = w/alb. a lwr showed a negative allometric growth in both male (b= 2,78) and female (b = 2,85). the condition factor range between 0.72 and 1.27, average 1.003 indicating this species were well-being in their environmental. a specimen was normal weight 86.4% of male and 89.3% of female, indicating this species were well-being in their environmental. keywords: length-weight relationship, condition factors, caranx ignobilis
