Growth and Survival of Sargassum spp. with Different Total Ammonia Nitrogen Concentrations

Résumé

Sargassum spp. is grass the sea that enters in category brown algae macro which is still Not yet wide cultivated in waters beach so that tried cultivation scale laboratory with treatment fertilization nutrients macro. Research This done for analyze resilience life and growth on Sargassum spp. with different Total Ammonia Nitrogen (TAN) concentrations. This research method uses an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments (P0: No Concentration, P1: TAN Concentration 0.010 ppm, P2: TAN Concentration 0.025 ppm, P3: TAN Concentration 0.050 ppm, P4: TAN Concentration 0.075 ppm) and 3 replications, so that there are 15 total experiments. Sargassum spp. maintenance was carried out for 15 days at the Aquaculture Environment Laboratory, Mataram University. The parameters observed include survival, growth weight absolute , rate growth heavy specific, long thallus , number strands leaves and water quality. Based on one-way anova test results concentration tested​ with level 95% confidence level obtained results that are not significant (p>0.05) against growth and resilience live on grass sea Sargassum spp. Results of the second order polynomial regression test between TAN concentration with growth grass sea obtained mark determination of R 2 (70-80%) which reveals strong relationship and 20-30% is influenced by other factors. The concentration given to maintenance This no utilized for growth Sargassum spp. however used for endure life come to the phase death. Based on the results obtained, then can concluded that the concentration of TAN given Still low. Because of that that, for study furthermore recommended use higher concentration of TAN high and use coral dead as substrate.
