Abstract

ABSTRACT

Skeletonema costatum is a good species phytoplankton for natural food since it has high chemical contents. The research aims to know salinity influence to the growth of S costatum’s and its optimum salinity. Experimental method is used with 4 treatments and 1 control. The primary research done to identify observation time and accurate interval salinity. Result of the primary research showed that S costatum’s growth can be observed clearly in every 18 hours and salinity level with interval of 3 ⁰/_00. The salinity treatments used 23⁰/_oo, 26⁰/_oo, 29⁰/_oo, 32⁰/_oo, and 35⁰/_oo because of it’s salinity range of S costatum. Cell density in each bottle sample is 20.000 cell/liter. The maximal population growth of S costatum at salinity 23 ⁰/₀₀ is 2,5 x 10⁴ cell /mL, salinity 26 ⁰/₀₀ is 2,58 x 10⁴ cell/mL, salinity 29 ⁰/₀₀ is 3,03 x 10⁴cell/m, and at control salinity 32 ⁰/₀₀ is 4,08 x 10⁴ cell/mL, while at salinity 35 ⁰/₀₀ is 3,16 x 10⁴cell/mL. From the observation found that water quality of media is suitable to support population growth of S costatum. The best salinity for the growth of S costatum population is on the treatment of 32 ⁰/₀₀salinity where the cell grown very fast and only need short time to reach out the top population. Whereas the optimum salinity is 33,26 ⁰/₀₀ on density of 3,48 x 10⁴ cell/mL.

Keywords : Skeletonema costatum, growth, optimum salinity.
