The bighead carp were introduced in 1992 as a part of a national study done to examine if the species could be effective in reducing nuisance algal plaguing ponds. The fish were to be removed at the conclusion of the study in 1995, however bighead carp persisted in the waters.
Sounds like they forgot they were there. So those fish were 32+ years old? I wonder if they were causing any problems. Apparently weren’t breeding - they didn’t say why (either sterilized or only one gender, I’d guess).
If they were smart, they would only have selected one sex for the study. That or water temperatures/seasons just happen to not be compatible with their eggs.
Because OP left zero context;
14 Bighead Carp from East Asia that were intentionally planted in 1992, but never properly removed were fished out of a pond.

Thanks for that. Even more detail:

Yeah was wondering why they didn’t reproduce. And how they found them all, were they tagged somehow?
Chum the waters and Carp will show up, it’s a very odd form of fishing.
