MOINIDAE, GOULDEN 1968 (family)
Second antenna with dorsal branch 3-segmented and
ventral branch 4-segmented. First antenna long,
moveable, situated on the ventral side of the
large head. For further information see
Goulden (1968).MOINA, (BAIRD 1850
Ocellus eye absent, only compound eye present.
Food: algae, bacteria and detritus. Preyed upon
by fish and phantom midge-larvae.
93 a. Distal claw on postabdomen without big spines.
The dorsal margin of the postabdomen has rows
of thin setae. Head rounded, without depression
over the eye, except on very large specimens.
Ephippium with 2 eggs. Size up to 1800 μm.
Often used in zooplankton cultures fertilized
with cowdung and soil to produce bacteria as food.
Reproduce up to 35oC. Lethal temperature is 48°C.
Found in eutrophic ponds and fertilized fishponds,
also in brackish water, up to 22 ppt salinity.
Common. (Figures 93a1, 93a2)

94 a. Distal claws on postabdomen with a row of small
spines decreasing in size distally. Adult measure
less than 1OOO μm (l mm). Ephippium reticulated
all over its surface. Shows remarkable affinity
for the cryptomonad algae, which evidently are
very good food sources (Lewis 1979b).
Showed a high degree of ephemeral patchiness
in Lake Lanao (Lewis, 1978d).
Pelagic in lakes, but more common in the
littoral among plants. Common.

and rice fields, also in salt lakes up to
