The population in the wild didn't actually *increase* per se..... they just happened to discover several previously-unknown populations in the intervening time.

If Bellatrix and Smeagol are indeed at Denver then jayjds2 is right about there being 5.8 at DLC
Ichabod died earlier this year
In Madagascar in 2011 there was one female kept at Zoo Ivoloina, and 3 males and 3 females at Tsimbazaza Zoo. Don't know if that's still correct.
All of the others at Ueno are offspring of the original pair except Mafi, who is the son of Hitchcock and one of the daughters produced at Ueno, Tiergarten.

So to correct Dave's summary:
Europe = 10.10.1 (split between Germany and the UK (England and Jersey) )
USA = 11.15 (split between Ohio, Colorado, North Carolina, Nebraska, Pennsylvania and California)
Japan = 5.4
Madagascar = 3.4 (assumedly)
This gives a world total of 63 (29.33.1)

Is there a possibility that other zoo(s) keep aye-aye(s) without even been considered in this management of aye-ayes. Zoos like in East Asia (including Japan), Africa maybe, or even Russia? or zoos in Europe and North America not members of EAZA or AZA, respectively?

Possibly, though that can be said for any species to be honest. I do not doubt that there are multiple bonobos kept by off-the-books zoos, and I already know of the male bonobo Tiby in Cirque Rech and a male and female bonobo in Morelia Zoo, Mexico, none of which are included in the studbook. So yes, there is a chance, but not very likely considering the size of the captive population.
Ivoloina received 4 extra Aye-Ayes in 2014, though I am not sure whether these are the animals now in San Diego. As their emergency enclosures etc were all sponsored by San Diego...
The fun thing of Aye-Ayes is that they were once thought to be the rarest of all the lemurs, but currently they appear to be the most widespread lemur species of them all....
No, the San Diego animals are from Ueno, DLC and born at San Diego respectively.
Thanks, then these 4 Aye-Aye should still be in Ivoloina.
I'm assuming they're 2 males and 2 females...?

And what was the total number of founders for all this world-wide captive population?
I can't tell you for the world, but for the US population, it is as follows:
2.0 imported in 1987
0.2 imported in 1998
1.3 imported in 1991
All are wild caught.
Those all went to the Duke Lemur Center. There could be others that I'm not aware of, though. Five of the founders are still alive.

Thank you jayjds2. I thought ShonenJake13 will know this for sure
Whoops, I've made a mistake. It was actually 2.0 imported in 1987. Got my numbers mixed up a bit! Sorry
Thank you jayjds2. I thought ShonenJake13 will know this for sure
One thing j can definitely tell you about the European founding animals is that they were brought to Durrell by the late Gerald Durrell himself. Not sure about individuals though.
The Vincennes Zoo in Paris had aye-ayes before Durrell's trip to Madagascar. It also had representatives of all the extant lemur families when I visited in 1988.
They had a *lot* of nice lemur species at Vincennes back in the late 1980s and early 1990s! Many of them are species which are not held in captivity at all now, even in Madagascar, and which I doubt will be held in captivity again......
Vincennes
Aye-Aye (Daubentonia madagascariensis) - held 1986 until 2004
Mongoose Lemur (Eulemur mongoz) - held 1986 until 2004; 2015 to present
Northern Bamboo Lemur (Hapalemur occidentalis) - held 1991 until 2008; 2010 until 2014; 2014 until present.
Greater Bamboo Lemur (Prolemur simus) - held 1987 until present.
Belted Ruffed Lemur (Varecia variegata subcincta) - held 1993 until 2008; 2012 until present.
Hairy-eared Dwarf Lemur (Allocebus trichotis) - held 1991 until 2002.
Western Fat-tailed Dwarf Lemur (Cheirogaleus medius) - held ???? until ????
Gray Mouse Lemur (Microcebus murinus) - held c.1986 until 2006.
Northern Giant Mouse Lemur (Mirza zaza) - held 1986 until 1993.
Fork-crowned Lemur (Phaner furcifer) - held 1986 until c.2002.
Red-tailed Sportive Lemur (Lepilemur ruficaudatus) - held 1986 until 1993.
Crowned Sifaka (Propithecus coronatus) - held 1987 until 2008; 2012 until present.
It perhaps goes without saying that I would dearly love for photographs of several of these taxa to be uploaded to the Zoochat gallery as part of my "Species Lost Since 1990" thread! Given the fact that collections in the United Kingdom held the Northern Giant Mouse Lemur until as recently as 2009 - albeit misidentified as Coquerel's or Southern Giant - it is quite a shame no photographs of this taxon are present in the gallery.
Truth be told I suspect there *were* photographs but that these were lost in the "Great Purge".......
Baby aye-aye at London has been confirmed as male and named Malcolm.
This changes the world population to:
11.10 in Europe
11.15 in USA
5.4 in Japan
5.6 in Madagascar (assumedly)
This changes the world population to:

The four that have passed are males Merlin and Norman Bates, and females Morticia and Angelique.
