      Abstract
      Penelitian mengenai aspek reproduksi ikan pepetek Leiognathus equula (Forsskal, 1775) penting dilakukan karena tingginya tekanan penangkapan dapat berdampak negatif terhadap keberlanjutan ikan pepetek . Penelitian ini bertujuan untuk menganalisis aspek biologi reproduksi ikan pepetek yang didaratkan di PPN Palabuhanratu. Penelitian dilaksanakan pada bulan September 2021 sampai Februari 2022. Jumlah ikan contoh yang diamati sebanyak 459 ekor. Hasil penelitian menunjukkan pola pertumbuhan ikan pepetek adalah allometrik negatif. Nisbah kelamin ikan pepetek jantan dan betina adalah 1:0,90, dengan jumlah ikan betina matang gonad lebih banyak dari jantan. Faktor kondisi ikan jantan dan betina ikan pepetek, yaitu 1,005. Ukuran pertama kali matang gonad ikan pepetek jantan dan betina adalah 163 mm 139 mm. Nilai IKG menunjukkan prediksi musim pemijahan pada bulan September-Oktober dan Januari-Februari. Nilai fekunditas ikan pepetek yang diamati berkisar 24.796–37.775 butir, dengan analisis diameter telur menunjukkan pola pemijahan ikan pepetek adalah total spawner.
       
      Research on the biological aspects of common ponyfish Leiognathus equula (Forsskal, 1775) is important because it is feared that the population of common ponyfish will decline in the future. This research aims to analyze the reproductive biology aspects of common ponyfish landed at PPN Palabuhanratu. The research was conducted from September 2021 to February 2022. The number of sample fish observed was 459 fish. The growth pattern of pepetek fish is negative allometric. Analysis of the sex ratio of male and female pepetek fish is 1: 0.90, with the number of gonadally mature female fish more than males. The average total condition factor of male and female pepetek fish is similar, which is 1,005. The size of the first mature gonads of male and female the common ponyfish was 163 mm 139 mm. IKG values indicate predicted spawning seasons in September-October and January-February. The observed fecundity value of the common ponyfish ranged from 24.796-37.775 grains, with egg diameter analysis showing the spawning pattern of pepetek fish is total spawner.
