TW 2400

Bivalve Applications

• Peak Load Supplement
• 100% live algae replacement
• Remote set
• Back-up feed supply
• For use with open tanks, silos, bottle upwellers, header tanks, cultch tanks and depuration tanks
• Effective for many species including artemia, crab, sea cucumber and some copepods

Bivalve Directions

1. Defrost overnight in a refrigerator.
2. When water is circulated with a centrifugal pump, such as with an upweller, add in front of the pump intake and the pump will disperse the algae cells.
3. When feeding into open tanks or header tanks, pre-dilute the algae 10:1 with system water
   a. Add system water to a small bucket.
   b. Add TW 2400 and stir.
   c. DO NOT BLEND; it is unnecessary and may damage the algae cells.
   d. Pour into larvae or spat tank.
   e. Pouring through a 20–micron screen can improve dispersion.
4. Feed according to the table below. Adjust dosage to meet the needs of your hatchery and larvae.
5. Refrigerate bottle when not in use 6. Use within 8 days of defrosting

TYPICAL FEEDING RATION

Larvae

Feed according to shell length. Shell length on a given day is an estimate. Larviculture may run up to 20 days.

Spat

Feed by Live Weight
• 0.5ml TW 2400 per gram live weight of spat per day

Broodstock Conditioning and Fattening

Typical Broodstock Feed Rates

• 0.025–0.05 ml TW 2400 per gram wet meat weight per day*

OR:

• 0.24–1.0 ml TW 2400 per adult animal per day (depending on feed ration and size*)
• Provides between 2% and 4% dry weight feed for dryweight of meat
