Transplantasi spons laut Petrosia nigricans
Spons merupakan hewan laut yang dapat menghasilkan senyawa bioaktif yang bermanfaat sebagai antibiotik, antijamur, anti virus, anti kanker, anti inflamasi, dan antioksidan. Tujuan dari penelitian ini adalah mengetahui pertumbuhan dan tingkat kelangsungan hidup spons Petrosia nigricans yang ditransplantasikan pada kondisi perairan yang berbeda. Metode transplantasi spons yang dipakai adalah fragmentasi (menanam potonganpotongan spons). Hasil penelitian menunjukkan bahwa pertumbuhan dan kelangsungan hidup spons dipengaruhi oleh perbedaan kualitas lingkungan perairan di Pulau Pari dan Pramuka. Rata-rata pertumbuhan mutlak spons Petrosia nigricans pada kedalaman 7m dan 15m di Pulau Pari masing-masing sebesar 793.26 cm3, 936.60 cm3 dan di Pulau Pramuka sebesar 493.19 cm3, dan 590.02 cm3. Rata-rata kelangsungan hidup spons Petrosia nigricans berkisar 90 - 100%.

Sponges are marine organisms which known to be able to produce bioactive metabolite as antibiotic, antifungal, antivirus, anticancer, antiinflammation, antioxidant. The aim of the research is to determine growth and survival rate of sponge Petrosia nigricans transplanted in different waters condition. Sponge transplantation use fragmentation method (by plant fragment of sponge). The result shows that growth and survival rate of sponge affected by defferences of waters quality in Pramuka and Pari Islands. Average of absolut growth sponge Petrosia nigricans on 7m and 15m depth in Pari Island are 793.26 cm3, 936.60 cm3 respectively and In Pramuka Island are 493.19 cm3, 590.02 cm3 respectively. Average of survival rate sponge Petrosia nigricans is 90 -100 %.
Key words : growth, survival rate, transplantation, Petrosian nigricans
