Pola Pertumbuhan dan Faktor Kondisi Udang Merah (Parhippolyte uveae) di Perairan Rawa Kawasan Pantai Koguna Kabupaten Buton, Sulawesi Tenggara
Abstract
ABSTRAK
Rawa udang merah (Parhippolyte uveae) berada di Desa Mopaano, Kecamatan Lasalimu Selatan, Kabupaten Buton dan merupakan salah satu destinasi wisata yang unik karena terdapat organisme udang merah yang tidak seperti udang pada umumnya. Tujuan penelitian ini untuk mengetahui pola pertumbuhan dan faktor kondisi udang merah di perairan rawa kawasan Pantai Koguna Kabupaten Buton. Penelitian dilaksanakan pada bulan Oktober sampai Desember 2021. Metode penelitian yang digunakan adalah metode purposive sampling berdasarkan keberadaan udang merah. Pengambilan sampel udang merah dilakukan pada 3 kelompok pengamatan. Pengambilan sampel dilakukan pada setiap kelompok dengan alat tangkap waring. Udang yang ditemukan dihitung jumlahnya, diukur panjang karapasnya menggunakan kaliper dengan ketelitian 0,01 mm, dan ditimbang bobot tubuhnya menggunakan timbangan digital dengan ketelitian 0,01 gram. Selanjutnya dilakukan analisis untuk mengamati pola pertumbuhan dan faktor kondisinya. Hasil analisis hubungan panjang karapas dengan berat udang merah memiliki nilai konstanta b<3 pada ketiga kelompok pengamatan yang menunjukkan pola pertumbuhannya bersifat allometrik negatif. Faktor kondisi menunjukkan bahwa kelompok pengamatan 1 memiliki nilai yang lebih rendah dibandingkan kelompok pengamatan lainnya. Nilai faktor kondisi yang rendah diduga kuat berkaitan dengan ketersediaan makanan, reproduksi, dan faktor lingkungan.
Kata Kunci: faktor kondisi, hubungan panjang-berat, Parhippolyte uveae, Pantai Koguna, pola pertumbuhan,
ABSTRACT
The red shrimp (Parhippolyte uveae) swamp is located in Mopaano Village, Lasalimu Selatan District, Buton Regency and is a unique tourist destination because there are red shrimp organisms that are not like shrimp in general. The purpose of this study was to determine growth patterns and condition factors of the shrimp ) in swamp waters at Koguna Beach area, Buton Regency. The research was carried out from October to December 2021. The research method was a purposive sampling based on the presence of red shrimp. Sampling was carried out in 3 observation groups. Sampling was carried out in each group by fishing nets. The number of shrimp found was counted, their carapace length was measured using calipers with an accuracy of 0.01 mm, and their body weight was weighed using a digital scale with an accuracy of 0.01 gram. Then an analysis was carried out to observe growth patterns and codification factors. The results of the relationship between carapace length and weight analysis showed a constant value was b<3 in the three observation groups which indicated that the growth pattern was negative allometric. The condition factors show that the observation group 1 shows a lower value than the others. It is strongly suspected to be related to food availability, reproduction and environmental factors.
Keywords: condition factors, growth patterns, length-weight relationship, Koguna Beach, Parhippolyte uveae.
