I say this as joke.....
you could put a small charge of C4 on the grass carp you stock, then when they have outgrown your welcome, say goodbye and push a button.
but I imagine that bowfishing would be your best bet....its a lot of fun too
This reminds me of active research focused on transgenic incorporation of an inducible fatality gene (IFG).
What a concept! Stephen King could certainly weave this idea into a thriller.
A normally benign dietary substance is used to trigger selective mortality of a trans-genetically modified population.
Theoretically,
the concept could be employed for managing grass carp populations - not to mention many others.
