Last year we introduced our koi to our pond that we rebuilt and surprisingly they spawned a bunch of eggs. As of right now I have like 30 baby koi and they are rapidly growing. Spring has just arrived for 2017 and we are planning to purchase an ace knottless 1/2" Seine net to help catch them and cull out the ones we don't want.
I am also trying to purchase a holding box for the koi to mate in this season in hopes to protect the fry but Memphisnet does not carry any type of spawning holding boxes for sale. Mostly 1/8", 3/16", 1/4" size netting is sold. I have also seen posts about people using the fiberglass screen door netting from Lowe's or home depot but not sure if it will work. I want to construct something that will allow my koi to have a large space to mate. Some of these commercial made spawn nettings are too small for my koi. My pond is around 6000 gallons and is 4 ft deep. All ideas welcome! Thanks everybody!
