      Abstract
      Fitoplankton merupakan organisme autotrof yang dapat memanfaatkan energi karbon dari CO2 dengan bantuan sinar matahari melalui proses fotosintesis. Tujuan penelitian ini untuk menduga potensi perikanan alami melalui kandungan karbon biovolume sel fitoplankton dan kandungan klorofil-a di Waduk Jatigede. Pengambilan contoh dilakukan pada bulan Februari, Maret, dan April 2021 pada enam titik Stasiun. Pengukuran biovolume sel dilakukan menggunakan metode geometrik. Hasil penelitian menunjukkan kandungan karbon fitoplankton tertinggi terdapat di zona riverine. Uji statistik dilakukan untuk mengetahui perbedaan kandungan karbon fitoplankton di setiap zona. Hasil uji menunjukkan kandungan karbon fitoplankton di setiap zona relatif sama. Analisis potensi perikanan alami dilakukan berdasarkan nilai karbon biovolume sel fitoplankton dan kandungan klorofil-a. Potensi perikanan alami berdasarkan pendekatan karbon biovolume sel fitoplankton sebesar 6,66 ton/tahun, dengan nilai produktivitas primer sebesar 92,57 gC/m2 /tahun. Potensi perikanan alami berdasarkan kandungan klorofil-a sebesar 10,77 ton/tahun, dengan nilai produktivitas primer sebesar 413,35 gC/m2 /tahun.
       
      Phytoplankton is an autotrophic organism that can utilize carbon energy from CO2 with the help of sunlight through the process of photosynthesis. This study aimed to estimate the potential of natural fisheries through phytoplankton cell biovolume carbon content and chlorophyll-a content in Jatigede Reservoir. Sampling was conducted in February, March, and April 2021 at six stations. Cell biovolume measurements were made using the geometric method. The results showed that the highest phytoplankton carbon content was found in the riverine zone. Statistical tests were conducted to determine differences in phytoplankton carbon content in each zone. The test results showed that the carbon content of phytoplankton in each zone was relatively similar. Natural fisheries potential was analyzed based on phytoplankton cell biovolume carbon value and chlorophyll-a content. The potential of natural fisheries based on the phytoplankton cell biovolume carbon approach was 6.66 tons/year, with a primary productivity value of 92.57 gC/m2 /year. Natural fisheries potential based on chlorophyll-a content is 10.77 tons/year, with a primary productivity value of 413.35 gC/m2 /year.
