Description An extremely small rotifer was isolated from the micro zooplankton
samples collected during February, 2014 from Havelock islands of
Andaman and Nicobar Islands. The species was identified as Colurella
adriatica Ehrenberg, 1831 (Family: Lapadellidae). Its lorica length under
culture period ranged from 47.530 to 98.868 μm and width from
34.308 to 56.277 μm. The size of the eggs, neonates and adults are
also documented. Comparison of size of C. adriatica with Brachionus
plicatilis (L type) and B. rotundiformis (S and SS type) revealed that
C. adriatica is smaller in length and width than the SS-type rotifer which
is currently used as a first feed in marine tropical fish larval rearing.
However, the larvae of many marine food fishes including groupers and
high value marine ornamental fishes are unable to consume the SS-type
rotifers as a first feed due to their extremely small mouth gape. The
culture of C. adriatica was carried out using Nannochloropsis oculata
Diet-I), N. oculata and yeast (0.01g/litre) (Diet-II), Yeast (0.01g/litre)
alone (Diet-III). Average population density of C. adriatica with these
diets reached a maximum of 1000 nos. of individuals /ml on 10th day
of culture on feeding with Diet-I; 950 nos. /ml on 14th day (Diet-II) and
650 nos. /ml on 15th day of culture (Diet-III). Diet I &II and Diet II &III
did not show any significant difference (P>0.05) whereas, Diet I and III
showed significant difference (P
