What is FishLung GEN2?

FishLung® GEN2 is a livewell oxygenation system engineered to deliver safe, consistent, high-concentration oxygen directly into your livewell. Unlike traditional aeration systems that introduce atmospheric air containing only 21% oxygen, FishLung® GEN2 draws in the same air and removes nitrogen, supplying 90%+ oxygen to the water.

When dissolved oxygen levels drop to unsafe ranges, fish may survive weigh-in yet succumb to oxygen stress hours or even days after release. FishLung® GEN2 addresses this hidden risk by maintaining optimal oxygen levels throughout transport and confinement.

The result is healthier fish, improved survival during tournaments, and significantly better post-release outcomes. Whether you are a professional angler competing at the highest level or a conservation-minded weekend angler, FishLung® GEN2 is an essential upgrade for responsible fish care.
