Lessons Learned "Quick Hits"

Apologies on the missing May update. We are soliciting short lessons-learned from hobbyists: events that possibly left you sadder, but measurably wiser. Have a good one? Please send it to the  . Here is are two insights from board member and master breeder Matt Lyon:

Retaining a Variety of Color Patterns in Edo Spawns

Coloration of young Japanese Edonishiki is always wonderfully varied among fish from the same spawn. Besides the mattes & metallics, you will tend to observe 5 or 6 primary calico color types from any given spawn. And each successive generation will tend to produce wildly different primary calico color types than the last. The development and stabilization of each calico color pattern are equally unpredictable, which makes for an interesting, but challenging culling process. Due to all these factors of uncertainty, it is recommended to retain a variety of color patterns when culling Edos (and possibly other calico/nacreous varieties) for at least a year, to allow time for mature coloration to develop. Obviously this must be done within reason given the available time and space of the hobbyist, but this approach will help increase the hobbyist’s odds of producing at least a few fish of the desired color pattern from each spawn raised.

Focus on Mother’s Headgrowth in Edo & Ranchu Spawns

It can be frustrating to breed high quality Edonishiki or Ranchu and raise the fry only to find that each generation has poorer headgrowth development than the last. Close observation has shown that careful selection for female breeders with well-developed hoods can result in drastically improved headgrowth on the resultant juveniles. Although large hood development is often found to be a secondary sexual characteristic of male fish, in some goldfish bloodlines there seems to be more of a tendency for young fish to inherit their headgrowth traits from their mother. This may also hold true for other types of goldfish, but the author of this “quick hit” has not tested it on other varieties.

Apologies again for the missed May update ... hope these valuable insights make up for that!
