PERKIRAAN UKURAN STOK FAUNA BENTK DENGAN METODE ...

Dengan menggunakan Persamaan (5)
nilai-duga biomassa ikan demersal per stratum
kedalaman dapat dihitung. Demikian
pula ragam dari masing-masing nilai-duga
biomassa per stratum dapat ditentukan dengan
menggunakan Persamaan (7). Selanjutnya
dengan menggunakan Persamaan (10)
estimasi MSY dapat diperkirakan, yakni
dengan menganggap nilai M = 1, yakni sebagai
nilai rata-rata mortalitas alami dari
berbagai jenis ikan, dan dengan anggapan
bahwa stok diluar kedalaman 20 m masih
belum diusahakan secara intensif. Sehingga
nilai-duga MSY:
MSY = 0.5 (1) (605.6) x 1000 =
302.8 (x 1000 ton).
