Applications & Benefits
Directions & Feeding
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.
When feeding into open tanks or header tanks, pre-dilute the algae 10:1 with system water.
Add system water to a small bucket.
Add Shellfish Diet 1800 and stir.
DO NOT BLEND; it is unnecessary and may damage the algae cells.
Pour into larvae tank or spat.
Pouring through a 20–micron screen can improve dispersion.
Feed according to the table below. Adjust dosage to meet the needs of your hatchery and larvae.
Refrigerate bottle when not in use.
Typical Feeding Ration
Feed according to shell length. Shell length on a given day is an estimate. Larviculture may run up to 20 days.

Feed By Live Weight
- 0.7ml SHELLFISH DIET 1800 per gram live weight of spat per day
- Works for all sizes of spat

Feeding Broodstock Conditioning and Fattening
Typical Broodstock Feed Rates:
0.03 – 0.06 ml SHELLFISH DIET 1800 per gram wet meat weight per day
0.3 – 1.2 ml SHELLFISH DIET 1800 per adult animal per day (depending on feed ration and size*)
*The required food ration for conditioning is based on the meat weight of the adults. It is usually between 2 and 4% of the mean dry meat in dry weight of algae fed per day. This is approximately equivalent to 0.03–0.06ml TET 3600 per gram of wet meat weight.

Shellfish Diet 1800 is a known entity and is of consistent quality. It provides that solid foundation for our operation to continuously push for efficiency.
Excellent service and delivery. Shellfish Diet always works well for our oyster remote setting process.
We have successfully used Shellfish 1800 diet for native mussels during their time in quarantine. This has worked well as a feed source during this period.
