Lobster pasir (Panulirus homarus Linnaeus, 1758) merupakan komoditas
perikanan bernilai ekonomi tinggi yang tersebar di perairan tropis, termasuk Teluk
Penyu, Kabupaten Cilacap. Penelitian ini bertujuan membandingkan produksi telur
lobster pasir pada musim kemarau dan musim penghujan, serta menganalisis
hubungan dan perbedaan parameter morfometrik tubuh dengan produksi telur
lobster pasir. Sampel lobster pasir bertelur dikoleksi secara purposive sampling dari
nelayan setempat, dengan parameter yang diamati meliputi berat tubuh, panjang
karapas, panjang abdomen, dan jumlah telur. Produksi telur dihitung menggunakan
metode gravimetrik, yaitu dengan menimbang total massa telur, mengambil sub-
sampel seberat 1 g menghitung jumlah telur dalam sub-sampel secara manual, dan
menghitung total berdasarkan berat keseluruhan. Penelitian dilaksanakan pada Juni
dan Desember 2024, sedangkan analisis data dilakukan di Laboratorium Pescica
Marina Fakultas Perikanan dan Ilmu Kelautan, Universitas Jenderal Soedirman.
Hasil penelitian diperoleh produksi rata-rata telur pada musim penghujan lebih
tinggi yaitu 128.401 butir dibanding musim kemarau yaitu 101.630 butir. Pada
musim kemarau, panjang karapas dan berat tubuh berkorelasi negatif terhadap
produksi telur, sedangkan panjang abdomen berkorelasi positif. Sebaliknya, pada
musim penghujan semua parameter morfometrik berkorelasi positif dengan
produksi telur. Uji independent sample t-test diperoleh tidak terdapat perbedaan
antara kedua musim (p = 0,186 > 0,05). Guna menjaga stok dapat diakses jangka
panjang maka lobster bertelur di musim kemarau tidak ditangkap sehubungan
musim ini kondisi lingkungan kurang mendukung lobster dalam produksi telur
dibanding musim penghujan.

The scalloped spiny lobster (Panulirus homarus Linnaeus, 1758) is a high-value
fishery commodity distributed in tropical waters, including Teluk Penyu, Cilacap
Regency. This study aimed to compare egg production of P. homarus between the dry and rainy seasons, as well as to analyze the relationships and differences
between body morphometric parameters and egg production of schalloped spiny
lobsters. Barried scalloped spiny lobster samples were collected using purposive
sampling from local fishermen, with observed parameters including body weight,
carapace length, abdomen length, and egg production Egg numbers were
determined using the gravimetric method by weighing the total egg mass, taking a
1 g subsample, manually counting the eggs in the subsample, and extrapolating the
total based on overall weight. The study was conducted in June and December
2024, and data analyses were performed at the Pescica Marina Laboratory,
Faculty of Fisheries and Marine Sciences, Jenderal Soedirman University. Results
showed that average egg production was higher in the rainy season namely 128,401
eggs compared to the dry season namely 101,630 eggs. In the dry season, carapace
length and body weight showed a negative correlation with egg production, while
abdomen length was positively correlated. Conversely, in the rainy season, all
morphometric parameters were positively correlated with egg production. An
independent sample t-test indicated no significant difference between the two
seasons (p = 0.186 > 0.05). To ensure sustainable stock availability, it is
recommended that berried females in the dry season should not be harvested, as
environmental conditions during this period are less favorable for egg production
compared to the rainy season.
