Spawning return intervals for males and females have been estimated in the most general of time spans, and researchers have established only in the last 25 years that Atlantic Sturgeon eggs and larvae are freshwater obligates, dispelling the notion that spawning occurred in estuaries. Based on egg development stages, estimated spawning dates were September 17–18 and 18–19 at water temperatures from 25.3°C to 24.3°C and river discharge from 55 to 297 m 3 /s. Males weigh up to 90 pounds and females weigh up to 160 pounds. Ten of 13 females that were releasing eggs were caught during day lengths that were within 30 min of the autumn equinox.

Our collection of 38 eggs during the 21 d that spawning pads were deployed appears to be the first such collection (spring or fall) for wild-spawned Atlantic Sturgeon eggs. In all of the years, 105 fall adult females were caught: 73 were at stage 5, 26 at stage 6, and 6 at stage 7.

Atlantic sturgeon are large pre-historic fish recognized by their five rows of protective scutes (bony plates), advanced barbel sensory system (similar to whiskers), as well as their downward facing protrusible mouths. Females that were releasing eggs were only captured at water temperatures that were between 21.5°C and 25.1°C. The egg is released from the female into the ocean where the male than releases its sperm to fertilization. Bony plates line their bodies.
