Improving Penduncle

[Ranchu Rancher]

Can I improve the penduncle of my TVR with diet or is it controlled be genetics?

Let me start. When the fish is young, you need to put them in shallow water (4" dept). It makes the fish swim horizontal instead of vertical.

Fred: When I got them I put them in 4 inches after several months I put them in a 50 gal rubbermaid in about 8 inches of water. I got one spawn so far and I have them in 4 inches .

This is what I do for my baby TVR. I put them in 4" of water until they reach 3" size. After that raising the water lvl to 8".

You can maximize development with optimal care, but the genetic raw material must be there as well.......

Johnny Hubschman "The Truth" who has bred more Ranchu than anybody on this page makes a strong historical point; work on only one trait at a time. If you are unsure do one spawn for peduncle and one for funtan, and then combine traits in future years

gary thanks for the plug .thats what ive been doing all along with faces backs shape swimming tails you name it ,i hope new breeders read this and ill expand what im saying,also will reveal secrets for feeding babies etc

You may be able to thicken the peduncle with diet, but you need to develop an eye for what to keep and what to cull. Cull any fish where the tail core (middle rib) extends into the bracelet (should be a clean ring between the peduncle and tail). Also any fish that are relatively weaker in the peduncle area than their siblings should be culled. I also like to view the fish from the side and cull any that have a very sudden tail tuck. These fish don't look as good when they get older. Look for a smooth gradual slope from the back to the tail.

Greg, I have no experience with SVR and that may be different as the SVR's peduncle does not have the same significance as it does with TVR. John2 can give guidance on this). As far as TVR's are concerned Dan's above post sums it up, if you haven't got the raw genetic material then no amount of pampering will make any material difference. To think otherwise is I'm afraid just wishful thinking. Unfortunately of course the reverse is not true - good genes can fail to materialise to their full extent in the phenotype if husbandry is not good. I beleve that a good "swim" is essential in the development of strong peduncles, tails and tail shoulders; my Ranchu have a minimum of a
4ft 6ins swim from the time they hatch. Special foods for development of peduncles should be unnecessary as the peduncle should strengthen and thicken with normal growth and exercise (as long as you've got those genes) but of course no amount of special food, care and attention will encourage the growth and development of good tail shoulders and this desired characteristic alone probably features highly when culling Ranchu from the fry stage through to the young fish stage. In my view too many home made receipes add fat and bulk and a quality TVR should be "powerful", not "fat".

Quality proteins plus adaquate stimuli(exercise) = muscle........ "powerful"

...kind of like athletes doing weight training to develop more muscle mass. But genetic factor is probably the most important aspect of peduncle development.

[Cincy Ranchu]

You can bred what you have and cull for that trait only and make improvements over two or three generations, the alternative is to buy one thick peduncled fish and start a paralell line and cross back after a few generations. If you choose the outcross path, hand pick the fish from a tank of sibblings

genetics ,live food and space to swim also red wiggler worms are a good source of clean protein
