Artemia sp. is extremely important live feed to the aquaculture world. The protein
content in microalgae is important to produce a high quality Artemia sp. The objective
of this study were to assess the effect of copper exposure on growth and protein
content in Nannochloropsis sp. and in Artemia sp. after being feed with microalgae
contaminated with Cu. In this experiment, Nannochloropsis sp. were exposed to
different concentration of Cu (0, 0.0l, 0.1, 1 and 10 mg/l) for 8 days. Growth of
microalgae (chlorophyll a, carotenoid & dry weight) and protein content was measured
based on Day 0, 2, 4, 6 & 8. Based on the highest concentration of Cu that give effect
on growth of microalgae, the Artemia sp. were feed with microalgae contaminated
with 10mg/L Cu for 7 days. The growth of Artemia sp. was measured based on
mortality, cell size and protein content. Result showed that Chlorophyll a (1.925 mg/L
Chl a), carotenoid (0.610 ug/ml) & protein content (1.37%) in microalgae were highest
at 0.01 mg/L Cu (Day 8). Based on this study, 10mg/L Cu give an adverse effect on
the growth & protein content of Nannochloropsis sp. and also affected the growth of
Artemia sp.
