Marine hatchery has rapidly developed in recent years, one factor to support this
is the sufficient amount of fish consisted of food. Natural food and artificial food.
One type of natural food that given to fish in the larval stage is zooplankton
Oithona sp. which containing good nutrition for supporting fish growth. The
purpose of this study is to determine the differential of fermented food and
combination of natural food on zooplankton Oithona sp. growth rate. This research
has been carried out in the Center for Mariculture Development agency of
Lampung in January 2014 through February 2014. Completely randomized design
(CRD) was applied consist of 6 treatments (P1: 100% Natural food A, P2: 100%
Natural food B, P3: 100% Fermentation food, P4: 50% Fermentation food + 25%
Natural food A + 25% Natural food B, P5: 50% Fermentation food + 50% Natural
food A, P6: 50% Fermentation food + 50% Natural food B ), with 4 repetition.
Parameters used for this study were population density, populations specific
growth rate, proximate analysis and water quality. Data were analyzed by using
analysis of variance (ANOVA) followed by Least Significant Difference (LSD) test
at α=5%. The results showed that the natural food A (Porphyridium sp.) 100%
gives the highest population density of Oithona sp. ie 170 ind /l and the highest
specific growth rate of Oithona sp. ie 3.77% / day.

Keywords: Specific growth rate, Fermentation food, Natural food, Oithona sp.
