Abstract

Response pigment and ecological is major factor of photosynthesis. Quantity of chlorophyll a,b are not same in Gracilaria, though in one genus. Difference fluctuation ecological conditions on waters; (Station 1): estuaries, (Station 2): coastal, (Station 3): 100m from the shoreline, based on literature study will affect the rate of  photosynthesis. This research aims  need to measure of quantitatively pigments (chlorophyll a,b) and carbohydrate to know the difference. Method by purposive random sampling; chlorophyll a,b using UV-Vis spectrophotometer; carbohydrate with analysis by difference; also control  physical and chemical parameters of waters. Results show the chlorophyll a, b and carbohydrates in G. verrucosa (163.58 ± 8.90mg /L;79.32 ± 5.53 mg /L; 37.19 ± 1.50%); G. gigas (128.01 ± 7.2 mg /L;117.76 ± 5,85mg /L; 44.48 ± 0.90% ) and G. salicornia (100.36 ± 23.35mg/L; 93.73 ± 11,59mg/L; 36.94 ± 0.72%).

Abstract

The aim of this research was to determine the copepod daily feeding to Dunaliella salina and Chlorella sp because the research of copepod daily consumption to the phytoplankton in the sea was a part of discovering the water productivity. The determination was needed in the laboratory experimental method, in order to qualifying the biomass and energy transfer of sea food web / chain. The observation based on the laboratory experimental method and conducted in the Hatcehery and Laboratory of Alga, Marine Station, Teluk Awur Jepara. Four treatment were applied during the observation, i.e.: A. D.salina 20 litre; B. D.salina  2 litre; C. Chlorella sp 20 litre; D. Chlorella sp 2 liter. The copepod grazing rate was determined base on parameter of cell phytoplankton/ ml/ hour/ copepode. There were 4 series observation. The observations were done for 36 hours with 3 hours interval. The data collected was arranged as copepod daily consumption and analyzed using MAXIMS Analysis Models. The highest copepod daily grazing rate was 88.02 ± 44.18 cell phytoplankton/ ml/ hour/ copepod for D.salina on 20 liter volume of media. While the lowest one 50.16 ± 43.99 cell phytoplankton/ ml/ hour / copepod for Chlorella sp on 2 liters volume media. The Copepod daily grazing model tends to form a constant model for D.salina on 20 liters of media and proportional model for 2 liters volume of media. The Chlorella sp on 2 liters volume of media graze by the copepod showed the same model for constant and proportional model. The water quality of the media remained in tolerance range to support the grazing rate of copepod to the phytoplankton during the research.
