Abstract

Abstract: The research was aimed to analyzed ecologically feasibility and prospective of Pacific white shrimp ( Litopenaeus vannamei ) cultivation in Rokan Hilir Regency and City of Dumai. The sudy was conducted from January 2017 to April 2018 in 5 sub-districts; Sungai Sembilan (City of Dumai), Sinaboi, Rimba Melintang, Bangko and Batu Hampar (Rokan Hilir District), Riau Province, Indonesia. Water samples were collected at the Senepis River, Nyamuk River, Sinaboi River, Teluk Dalam River, RKT plot and Camp Pemda in the Diamond Raya Timber concession area. It was noted; pH (5.22-7.0), salinity (5.0 to 22.5), phosphate (0.4-1.263 mg/L), ammonia (0.03-0.352 mg/L), nitrate (0.346-0.379 mg/L), CO2 (15.980-123.685 mg/L) DO (2.7-5.7 mg/L) COD (70.4-114.4 mg/L), BOD (4.85-6.4 mg/L) and number of Coliform bacterial cells (7.0-233.05 cfu/100 ml). The dominant species of fish caught in river waters are common species, as in zooplankton, phytoplankton, benthos, and manngrove community. Based on species data, abundancy index, diversity index, homogenity index and dominance index shows that the waters are still in normal condition. The study conclude the area is still in normal condition and suitable for Pacific white shrimp cultivation.
