Bangaii breeding
- Thread starter RonD
- Start date
After reading a good portion of this incredible paper on them ( http://www.raingarden.us/banggaimanual.pdf )..."A. Establishing broodstock" it looks like 6 was the magic number but one died. so five???? They had a another 48 fish and they all died but one that did reproduce but it died as well... as did the young within a month... so I don't really know even after reading most of the paper.. very interesting read none the less. Can anyone shed a bit more light on the subject.
Seems like there is a Geneticists convention somewhere as many threads regard this subject ! 
Anyway I like it. 
As baggais come from a small range and lack a pelagic larval stage (limited dispersion), inbreeding, at some range, may have taken place in the wild.
I´ve read some time ago it wouldn´t be a problem to a breeder for the near future, even in species with a pelagic larvae. (I think it was Kathy question on her clowns)
Anyway, I´'d better wait to Frank on this.

Hey guys-
Great question, and one we have pondered over for many years.

Second there have been reports and photos around of banggais w/ stunted tails, twisted spines and reduced lower jaws, so yes inbreeding is a concern, however, if you breed responsibily and cull out the deformed/malformed, and use healthy broodstock you should be okay.
IIRC a recent survey of genetics of the banggai population reported only like 20 unique mtDNA polymorphisms, so it might suggest that founder numbers are quite small. It is unclear what effects inbreeding good/bad, or neutral may have on captive bred populations.
However if you do have the opportunity to extend your genetic pool, i would highly recommend it.

Animals can handle a certain amount of in breeding. The fancy guppy is a good example. I bred them for 2.5 years. Eventually, your inbred bloodline becomes weak. After several generations you will start to notice undesirable characteristics.Like the fancy guppy, the BC's will pass on undesirable traits. Make sure you start with a healthy stock, preferably captive bred.
There are remote tribes of native people, and even religious groups here in the US, that are only allowed to marry individuals from the immediate community. This practice has been going on so long that people from these cultures are regularly born with extra fingers or toes. This comes from a "stagnant" genetic pool.
Both captive and wild animals often have no other choice. Our world is everchanging. Genetic diversity plays a major role in keeping species, as a whole, alive.

A lot of experience with salmon and trout (where there is a lot of data) suggests that your fish would really have to be in-bred for there to be a notable increase in congenital deformities in your population.
Frank, reading your comments suggest to me (at least) that nutrition (and nutrition-related pathologies such as those noted in your post) would be more of an issue than inbreeding depression. Any comments?
