Brine Shrimp EggsOur Premium Grade 90% hatch-out amounts to 250,000+. NPG (nauplii per gram). Brine shrimp egg hatch-out can vary greatly, even from harvests collected in the same season, from the same location. For this reason, we carefully test batches of brine shrimp eggs before buying the product. We only purchase the highest quality product available from the Great Salt Lake, to offer our customers. Some years produce a higher quality product than others, and some collectors get luckier on the quality of their harvest. We test the brine shrimp eggs with our own fish and evaluate their effectiveness at obtaining good growth levels without problems. This assures that you will always receive the best brine shrimp eggs we're able to obtain.
