Pond Boss Forums INTRO Questions & Observations Bird leg fish transport

I would think fish egg dispersal by birds would normally fail when transferred to waters where fish already exist. Survival of fry is generally very low in waters where fish are already present. But in BOWs with no fish, it only requires that a pair survive to reproduce. In most cases, it requires a year for fry to mature and reproduce in significant quantity so as to inhibit the introduction of new species by small quantity of fertilized eggs. So there might be a time window of opportunity where multiple species could be introduced to a newly built BOW where small numbers of viable eggs are deposited by birds.
