Cargill LiquaLife ®
Cargill LiquaLife® products are liquid feeds for larval and post larval shrimp. Each drop contains pre-stabilized nutrient beads and direct-fed microbials suspended in a liquid medium—providing highly available nutrients to larval shrimp while helping prevent the accumulation of ammonia nitrogen in culture tank water. These products are designed to complement live feeds, such as algae and artemia, and completely replace conventional dry feeds.
Producers around the world have discovered the benefits of using the Cargill LiquaLife products in their shrimp hatcheries including
Better Water Quality
Unlike dry feeds which quickly breakdown and pollute the water, especially when used at high concentrations, LiquaLife's pre-stabilized nutrient beads are highly water stable. This means they remain intact until eaten by the shrimp —and with the help of LiquaLife's probiotic bacteria, help prevent the accumulation of toxic ammonia.
More Consistent Nutrition
Hatchery owners know that attention and care of larval shrimp is critical, especially in feeding. The nutrient beads in Cargill LiquaLife products provide highly available nutrients to larval shrimp and their water stability help ensure that the nutrition is delivered to the animal. Faster Development and Growth
The consistent nutrition and better water quality provided by the Cargill LiquaLife products help improve the rate of growth and metamorphosis of shrimp larvae. This can shorten cycle time in the hatchery or result in larger, stronger PL being stocked into the pond.
Easier Feeding
Cargill LiquaLife products are simple to use. Just shake, twist open the spout, disperse the recommended volume in a small amount of water and pour directly into the tank. And because the nutrient beads remain intact until eaten by the shrimp, it is easy to adjust feeding to meet the actual needs of your larvae with less concern of overfeeding and water pollution.
Cargill LiquaLife: Z-M, M-PL and PL
The Cargill LiquaLife Hatchery Program is designed to meet the needs of all stages of larval shrimp. There are three products in the Cargill LiquaLife Hatchery Program : Z-M, M-PL, and PL. Each product is appropriately sized to meet the needs for a particular stage in the larval development. Please see the Cargill LiquaLife Hatchery Program for more details on using each of the Cargill LiquaLife Products or estimating the amount of Cargill LiquaLife for your hatchery.
Please see our LiquaLife brochure (PDF 327KB) for more information on these products.
Cargill LiquaLife ® Hatchery Program
Feeding Program Table
Feed LiquaLife® Z-M, M-PL and PL products to penaeid shrimp larvae and postlarvae stocked as nauplii at 100,000 to 150,000 per ton of seawater (SW). Divide daily ration into 4 to 6 feedings per tank daily. For best results, feed as a complement to a sound program of live phytoplankton, preferably log-phase Chaetoceros sp. and newly hatched Artemia nauplii.
Adjust the feeding ration up or down according to your production objectives and to allow for variations in the specific conditions of each tank.

The Cargill LiquaLife ® Hatchery Program
How to Use Cargill LiquaLife®: estimating amount needed.
a.) |
Using the Cargill LiquaLife ® Hatchery Program Feeding Table , determine the total amount of LiquaLife needed per tank until harvest. |
|
|
b.) |
Convert liters/tank to kg/tank (x 1.1). |
|
Note: the density of LiquaLife is approx. 1.1 g/mL (1.1 Kg/L) |
|
|
c.) |
Multiply this quantity by the number of tanks in your hatchery. |
|
|
d.) |
Calculate how many cases of LiquaLife you will need to order in either type of packaging: |
Cargill LiquaLife Packaging Options
- 1-kg pouches, 12 ct. case (12 kg case wt.)
- 4.5-kg bottles, 6 ct. case (27 kg case wt.)
- 12-kg bottles, 2 ct. case (24 kg case wt.)
