You estimate the number of fish in the pond as "on hand " but the number of spawned or surplused is accurate as they have to handle each fish.

Bingham has been known to keep the trap closed early in the year and the fish stay in the river as it is a better way to hold the fish. I got two hatchery hens last week and both had skeins around 1 to 1 1/4 inches in diameter. Way off being ready to spawn.
