Abstract

Penelitian ini diharapkan mampu memberikan informasi ekologis Thalassina anomala terutama yang berkaitan dengan arsitektur relung T. anomala dan peranannya terhadap kehidupan (interaksi timbal balik) biota akuatik lainnya yang ada di ekosistem mangrove Desa Tanjung Tiram Kecamatan Moramo Utara Kabupaten Konawe Selatan - Sulawesi Tenggara. Penelitian ini dilaksanakan pada bulan Oktober-Desember 2019 bertempat di Desa Tanjung Tiram Kecamatan Moramo Utara Kabupaten Konawe Selatan. Penelitian ini bertujuan untuk mengetahui secara detail arsitektur gundukan T. anomala di ekosistem mangrove Desa Tanjung Tiram Kabupaten Konawe Selatan. Penentuan stasiun penelitian menggunakan metode purposive sampling atau penetapan stasiun berdasarkan habitat alami lobster lumpur (T. anomala) di alam yakni pada ekosistem mangrove. Pengamatan relung T. anomala dilakukan secara langsung menggunakan metode random sampling. Parameter utama yang diamati pada penelitian adalah arsitektur relung (niche) antara lain tinggi gundukan, diameter atas gundukan, diameter bawah gundukan, kedalaman liang, diameter liang, kemiringan gundukan, kemiringan liang dan arah liang. Hasil pengukuran arsitektur relung lobster lumpur dan parameter lingkungan di analisis nonparametrik menggunakan uji spearmen, demikian juga dengan hubungan antara diameter atas gundukan dan lebar karapas lobster lumpur (T. anomala). Pola distribusi T. anomala pada setiap stasiun memperlihatkan pola yang acak (random). Kepadatan lobster lumpur (mud lobster) tertinggi diperoleh pada stasiun 2 (substrat berlumpur) dengan jumlah 4,5 ind/m2 sedangkan kepadatan terendah (1,5 ind/m2) diperoleh pada stasiun 3 dengan substrat kombinasi (lumpur, pasir dan kerikil). Terdapat korelasi yang sangat signifikan atau signifikan positif antara diameter liang dan lebar karapas (carapace width)  dari T. anomala. 95% dari parameter arsitektur gundukan tersebut memiliki korelasi yang signifikan, artinya hanya terdapat satu parameter yang tidak memiliki korelasi signifikan yakni hubungan antara parameter kemiringan gundukan dengan kemiringan liang (P>0,05). Diantara parameter tersebut tinggi gundukan dengan diameter bawah gundukan memiliki korelasi yang sangat signifikan (0,005<0,01) dan tinggi gundukan dengan kedalaman liang (0,026<0,05).
