Eggs and milt are ejected by sudden lashings of the caudal fin.
Male whites follow the writhing females, releasing their milt to fertilize the eggs.
Interruption or handling, even during spawning, prevents the discharge of eggs or milt .
"Soft roe" (also called "white roe") is the milt (male reproductive glands filled with seminal fluid) of the male fish.
I was taught how to strip fish of their eggs, then fertilise the eggs with a small amount of milt from a cock fish.
Thus, while attempting to ‘collect’ the egg-spots, the female ingests milt ejected near them by the male and ensures fertilization.
Eggs and milt from each individual were transported on ice to the Hagen Aqualab facilities (University of Guelph, Guelph, Ontario, Canada).
Rinella's meal, which took days of preparation and required ingredients like snapping turtle, swallow's nest and perch milt , was definitely not a novice-level culinary adventure.
I watched the darker, fierce-kyped male ease in front of those suns without once touching the female, and send milt melting down into her nest of stones.
When the male's body shivers the female is stimulated and the eggs and milt are released.
