ARTEMIA

Artemia cyst accumulation on the beach of the Great Salt Lake (Utah-USA)

dehydrated Artemia cysts in dormancy state

0.5 mm

cyst in breaking stage

Artemia hatching

instar I nauplius

established in 1978 upon suggestion of the FAO

Natural distribution of Artemia

Artemia dispersion birds - wind - man

NBrazil : first successful inoculation

inoculation of Artemia franciscana

in local saltwork

April 1977 Macau, RN - Brasil

first harvest of Artemia cysts in Macau (RN-Brazil) in August 1977

Southeast Asia :monsoon climate

seasonal salt work in the Philippines

washing / cleaning of fresh cysts with saturated brine

As of early ’80s several new commercial sources of Artemia cysts

ARTEMIA

biomass

1980’s :biomass production andharvesting in seasonal saltponds in the Philippines and in Thailand

use in nursery feeding ofmilkfish, sea bass, prawn and shrimp

biggest solar salt production in the world

FEED AND FEEDING FOR PANGASIUS SPECIES

In Vietnam

- Home-made feed

- Rice bran, soybean meal, trash fish

- Cooked and wet feed

- Food conversion ratio: 3-4
