The collecting eggs method from sturgeon using a catheter is described. A catheter made of artificial material is introduced through the urogenital opening into the body cavity of the female, and this permits opening the ovarian funnels. Next, exterior abdominal massage creates pressure that forces eggs into a collection receptacle. This method has been applied since 2004 to culture sturgeon fishes. The catheter method of collecting fish eggs can be an alternative method thanks to its low invasiveness and ease of application
