QUESTION:
Does
anyone have any experience with complete replacement of Artemia to L.
vannamei (PL-1 onwards) with dry feeds like Zeigler, Microfeast, or other? I
would like to know if this is possible and if there are species management
practices in order to ensure high survival and growth.

Just
try experimenting with the Ziegler P/L Ready.
You might begin at P/L 5 though.

For
the total Artemia replacement from PL1 onwards, I would suggest the use of
microencapsulated INVE Group has an alternative: Frippak CD#3 “Ultra”
specially from PL1-PL4 with a size from 80 to 150 microns.
I
will adjoin you data from our clients to give you tables of references about
their results.

COMMENTS 3 :
Is
this total Artemia replacement? Or is it supplement to Artemia? We were
recommended a Japanese manufactured micro-encapsulated Artemia replacement,
but did not get desired results. Is there any different management method?

At
PL-1 most hatchery people are looking for the cheapest feed they can find.
This is generally one of the dry diets or salmon starters/crumble. A more
water quality conscious diet would be a micro-encapsulated diet and one of
the cheapest on the market now is the ArteMac series from Aquafauna
Bio-Marine. It is a cluster microcapsule and looks like a grape cluster
under the microscope. It has very good buoyancy and good attractability for
L. vannamei and other penaeids. You can most likely get some samples for
trials if you want to be conservative in your purchase decision. My only
recommendation as far as the utilization of any artificial diet is to feed
small amounts as frequently as your labor arrangement will allow to maintain
water QC.

As
a replacement for Artemia from PL-2/4 onward you might consider AquaMats.
Their use has allowed several commercial hatcheries to eliminate the use of
Artemia. In addition to supplying continuously available natural feed,
AquaMats also provide structure in the water column which facilitates
grazing and resting behavior.

Artemia is not the only source of feeding you can
apply. Actually Artemia is not a marine species as is and is an
"adapted food" by the aquaculturist. Beside using some dry
diets you also can substitute Artemia nauplii with other live feeds,
such as cultured rotifers or fresh frozen feeds such as copepods, Artemia
biomass and some sources of Daphnia.
AFA Daphnia is a newly available fresh feed to the
aquaculture industry. These specific cladoceran are harvested out of Klamath
Lake in Oregon in the peak season of algae growth and Daphnia development.
The characteristic of this Daphnia is that they are naturally highly
enriched of this AFA blue green algae (Aphanizomenon flos-aquae)
giving them a very unique nutritional value. They are fairly high in a wide
range of lipids, saturated and poly-unsaturated, proteins and pigments.
Making a real blend of zoo and phyto nutrients.
Shrimp larvae feed easily on frozen feeds and with a
size ranging between 500 and 1500 microns; it fits well on most of the
larval cycle.
We currently have several South American hatcheries
working with it as a substitute to Artemia or as a nutritional supplement.
