چکیده
Nilai ekonomis teripang tinggi di pasaran dan mirip produk komoditi perikanan lain. ekonomi menyebabkan usaha penangkapan meningkat. Tingkat yang tidak seimbang dengan ketersediaan sumberdaya dapat mengancam keberadaan populasi. Penelitian ini bertujuan mengkaji kepadatan, sebaran ukuran, pola distribusi, populasi pertumbuhan perairan Letman. Metode pengambilan sampel adalah metode acak. Teripang ditemukan lokasi penelitian terdiri dari 8 jenis kisaran kepadatan sebesar 0,04-0.24 ind/m2. Hasil pengukuran suhu, salinitas pH pada diperoleh suhu berkisar 29-31°C, 28-31‰ 8.11-8.26. Ukuran panjang antara 10,5-31,52 cm, ukuran diameter 3,00-10,03 cm berat 51,5-611,09 gr. Pola distribusi mengelompok nilai Id 1,23. Keberadaan menunjukan keanekaragaman rendah (H’ = 0,42), keseragaman (E 0,234) dominansi tergolong stabil (C 0,83). b 2,16 sehingga allometrik negatif (b<3).
