This makes the second spring they have spawned. I made my own spawning ropes from yarn, tide them to a pole then laid the pole across the pond to let the fish get use to them for a few days. Just like last year, the water temp reached 68 degrees and morning brought a strong fishy smell, frothy bubbles and cloudy water. Doing a water change today and storms are expected over night. Might have more eggs tomorrow. Gotta get busy making more mops. I removed the others because the koi will eat them.
