Do you worry about the long term impact of inbreeding ?
I assume that was addressed to me re the plecos I with which I work. If so, the answer is no for two reasons.
First, I work with groups and that gives me more potential diversification than pairs or reverse trios.
Second, when I began working with zebras in 2006 I asked the person who mentored me if I should worry about inbreeding if I managed to get a second or third generation. I was told this should not be an issue for at least five generations. Considering the average time for a zebra to spawn for most folk who succeed is about three years. Some go sooner some later.
-My original zebra group was assembled over 3+ years well before I got them on 06.
-My second zebra group were farmed in Indonesia and should be genetically diverse as their breeding stock was acquired before the permitted list came into being. My understanding is they have well over 100+ breeding zebras
-My primary 173 group are wild fish assembled by an importer/exporter over a number of years as tjhir private collection.
-My second 173 group are tank raised fish and i cannot speak to their level of genetic diversity.
-My primary 236 group were offspring of the fish bred by Robert Budrovacn and are likely less genetically diverse than my average group. They were all wiped out by a heater malfunction and I used 10 of their offspring from 26 I had in a growout tank. I had also sent 23 of these to a friend to sell.
-My second 236 group are tank raised fisj from am assrtment of parent qwho rabge from standard 236 to a couple of generations along the way to creating a super white line. I cannot speak to their diversity at all.
-My super white 236 group were purportedly from the Budrovan super white line. While they are very pretty fish and cannot verify this beyond being told this was he case. I cannot say anything about their genetic diversity.
