Introduction
 live food for rearing of fish and crustacean
larval stages and ornamental fish
FORMS OF ARTEMIA USED IN
AQUACULTURE
Newly Hatched Nauplii
 Nauplii promptly fed
upon harvesting
 Nauplii metabolize,
grow, evade.
 Cold storage preserves
nauplii, slows metabolism,
retains nutritional value
and size up to 48 h
Instar I-II stages
Metanauplii
Enrichment
Metanauplii
 Size limits ingestion for
some larvae initially
 The enriched Artemia
make the utilization
worthwhile.
 The greater energy
content obtained per
particle
Other Forms Used
Specific Applications of Naupli and
Metanauplii
Shrimp Culture and Prawn
 fed algae prior to the Artemia, feeding of Artemia
too early result in competition
 0.1 nauplii/ml assure proper ingestion
Marine Fish Culture
 offered an Artemia after an initial week on a
smaller prey (rotifer, Brachionus plicatilis)
Fresh Water fish
 Artemia die after
30-60 min in fresh
water.
 Dead Artemia foul
the water
Aquarium Fish
 Improve Survival, vigor, and pigmentation
