Ocean Nutrition Brine Shrimp Eggs (Box)
Hatch your own live first food in under 30 hours. Ocean Nutrition Brine Shrimp Eggs are Great Salt Lake artemia cysts for hatching at home into live baby brine shrimp — a widely used first food for fry, small fish and filter-feeding invertebrates. Sourced from the Great Salt Lake and reporting a hatch rate above 90% under recommended conditions, they hatch out in 18 to 30 hours.
Key features
- Great Salt Lake strain — a widely used, reliable artemia source.
- High hatch rate — over 90% under recommended conditions.
- Fast turnaround — nauplii hatch within 18–30 hours.
- Feeds at the size fry need — freshly hatched nauplii are small enough for most fry to take straight away.

Ingredients
100% Great Salt Lake artemia (brine shrimp) cysts. There's no published guaranteed analysis for this product, since the cysts are hatched into live food rather than fed directly.
Setup, use and hatching
Brine shrimp eggs need salt water, warmth, aeration and, ideally, light to hatch reliably.
| Condition | Target |
|---|---|
| Water temperature | 28–30°C (82–86°F) |
| Salinity | Specific gravity 1.011–1.030 (roughly ½–2 level tablespoons of salt per litre of water) |
| pH | 8.0–8.5 (add a pinch of baking soda if it reads lower) |
| Aeration | Continuous, steady bubbling from the bottom of the hatchery |
| Egg density | No more than 2.5 g of eggs per litre of water |
| Lighting | A nearby lamp or fluorescent light helps trigger hatching |
Hydrate the cysts for about an hour before adding them to the hatching container. Hatching typically takes 18 to 30 hours at the warmer end of the temperature range, longer at the cooler end. Harvest the nauplii once hatched and rinse them in fresh water before feeding.
Storage
Keep unhatched cysts cool — around 2–6°C — to maintain hatch rate over time. A fridge, not a freezer, is suitable for storage between uses.
Suitable for, and not suitable for
Suits fry, small fish and filter-feeding invertebrates that need a small, live first food. Not needed for adult fish that already take flake, pellet or frozen foods comfortably.
Goes well with
A dedicated brine shrimp hatchery cone and an air pump make hatching easier if you don't already have a setup. Ocean Nutrition's Brine Shrimp Eggs Salt Mix combines the eggs and hatching salt in one pack if you'd rather not measure salt separately.
Common questions
How long do brine shrimp eggs take to hatch?
Around 18 to 30 hours, depending on water temperature — faster near 30°C, slower near the lower end of the range.
Do I need a special hatchery, or can I use a bottle?
A cone-shaped hatchery makes harvesting easier, but a bottle or container with steady aeration from the bottom will also hatch eggs.
How should I store the eggs I'm not using yet?
Keep them cool, around 2–6°C, ideally in the fridge rather than at room temperature, to preserve hatch rate.
Can I feed the cysts to fish without hatching them?
They're intended to be hatched into live nauplii first — that's what makes them useful as a fry food.
