Plans for feeding shrimp larvae

 

Life cycle

Description

Feeding plan

Nauplius

● The larva does not need to seek food from outside.

● The duration needs 50 to 110 hours.

● The nauplius is strongly attracted to light.

 

Zoea

●The stage is divided into 3 periods and the process usually takes 4 days.

● The direct heat and light from sun is detrimental to the development of the larvae.

● Let algae grow on the water or use a special water conditioner to cause the water to become a light brownish color.

Start feeding.

The activity of zoea is low and begins to catch plankton such as Spirulina and Skeletonema Costatum.

● Natural feed: Skeletonema Costatum, oyster eggs, oyster larvae and rotifers.

● Artificial feed: GAP, Genchem Larvin #0, HIFACS, Biomax #0

● Supplements:

Vitamins:EIKOSO, ASPARA-V

DigestivesGenchem Polytase

Water quality products: AMAZERM

This is known as the "excretion-dragging

Mysis

They swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. This is also called "inverted suspension phase" because the fry is suspended upside-down in the upper middle region of the pond water.

Usually in water temperatures of 27~29 with a salinity level of 32, the three phase of the Mysis Stage takes 3 days to complete.

● Natural feed: Brine Shrimp larvae, Rotifers and Copepoda.

● Artificial feed: use any one or some of the following options
(1)
GAP
(2)
Genchem Lavin #ZM
(3)
Both Biomax #0 & #1
(4)
Art. Artemia #1

● Supplements

Vitamins: EIKOSO, ASPARA-V

Post Larvae

PL1~PL5

Molting once everyday.

It is planktonic.

(PL1~PL20 stand for post larvae stage.)

 

● Natural feed: Brine Shrimp larvae and Copepoda.

● Artificial feed: use any one or some of the following options
(1)
Genchem Lavin #1, #2
(2)
Biomax #0 & #1, #2
(3)
Art. Artemia #2, #3

Post Larvae

PL5~PL20

After phase P5, most shrimp settle into life on the bottom or sides of the pond.

Shrimp larvae in the phase PL10~PL20 can be sold. The water temperature is around 27 on the 28th ~29thday.

● PL5~PL17 start turning red-color body.

● Artificial feed:

Genchem's shrimp flakes, Genchem Larvin

●PL18~PL20 become grow-out and turn black-color body.
