Why is it illegal to catch sturgeon?
Sturgeons are highly vulnerable to illegal fishing because they begin breeding relatively late, at about age 15, and they spawn infrequently—only every two to seven years. If populations are depleted, recovery is slow.
Is it illegal to eat sturgeon?

How can you tell when a fish is about to spawn?
The spawning season can be predicted by studying the occurrence of mature fish as well as by measuring the ova diameter. Gonadosomatic index (GSI) of the fish increases with the maturation of the fish, being maximum during the peak period of maturity and declining abruptly after spawning.
When do suckers spawn in the Susquehanna River?
Suckers spawn in early spring to early summer. Some species make mass migrations up tributary streams or travel to river riffles. Scientists have even noted some homing behavior, in which spawning Suckers returned to previously used spawning sites. Most Suckers scatter their eggs randomly.
