Key Findings
- In European hake, proper attachment of an oil layer to an oil droplet in eggs is crucial for embryo survival
- Eggs that float well have a higher chance of this essential oil layer attachment
- Egg buoyancy, and thus survival, is affected by changing ocean conditions like currents and salinity
