An interesting thread appeared on the BKA newsgroup concerning inbreeding or how many generations you could breed before they degraded. I dont think their has ever been a report or survey into any number of species & how many generations they have been taken to before degredation (if any) occurs. In the last issue N. furzeri was reported being inbred for 32 years which must hold the record. We have many fish in our tanks from 1990 collections. It would be interesting if members could let me know how many generations they have inbred a species/population for and give details of any deformities. I would print no names. This would prove an interesting subject.
The elegans group have always been a favourite for me and when elegans groups started to appear on the net I was interested, primarily in finding out if the old populations were still being kept. If you go to an auction in this country you have a hard time finding any, but listed below is the known worlds conservation list of the elegans group. Under each species are listed populations currently being maintained in captivity. Obviously I do not put in addresses of those keeping them. If you join a group these will be available to you. These groups are working groups and you will need to show you are doing something to maintain them. It's not a case of paying a membership and sitting back for the duration (like joining the BKA).
This list is as complete as I can get. It combines all known groups worldwide. I think it's impressive, but far from complete. Many populations seen in the past are missing, notably A. cognatum but I think now, with this worldwide co-operation of conservation, new populations will become part of this list. Many 'CI' or commercial import codes are being kept & this is important. Although we don't know the exact area of collection apart from 'an area close to an airport or landing stage' these are probably the only wild fish from the group we will see for a while given the troubles in that part of the world.
Alan & I have worked to distribute eggs from Kinshasa imports. The import from late last year is now producing, & young fish are growing on. These will go to the conservation groups as a priority to ensure future survival in captivity.
Calling a fish 'CI' is now something of a fashion & I don't want to label our finds thus. I have decided to start calling the wild fish we distribute by our own code but have not decided what to call it. We thought about TA but this could get confused or corrupted with Tanzanian collections.We put a code on them to seperate them for future breeding groups & with the knowledge that other African imports or contaminants will surely arrive in our tanks this year (being 2001/). We apologise for dropping yet another code on the killie world but we do seem to 'drop' on these wild fish & they must be kept seperate from other populations as, in many cases no exact collection information is forthcoming.
Angola remains the most unexplored, dangerous & most exciting place to explore in the future but I don't think this country will be open for a long while. Even then the collectors will have to brave land mines etc. Killie wise, little is known in this area of Africa but it will most probably reveal other elements of the Aphyosemion subspecies. Technology exists to find these mines through a balloon detection device but finance again is lacking. Perhaps our funds could be put to good use in this direction in opening up new frontiers.
Fp.nigerianum. I wonder if anyone has seen a photo of a population from Jiker which arrived in the UK from the USA a few years ago. I have been unable to find any information from the other side of the pond from whence they came but I put the photo in anyway as I cant recall seeing this one before. Thanks to Roger Gladwell for permission to use the photo. Roger is back in the fold. His fish house has been re-designed more times than I can remember. Those knowing Roger will know what Im talking about. Still, he does manage to keep fish going over many generations.

Czech imports of Fp. nigerianus/gardneri always arrive labelled as Akure. In fact, sometimes they arrive in the form of Akure, Nsukka, Lafia & the old Port Harcourt form but with larger red spots on the body. These are being distributed as Akure. I know gardneri are looked down on at auctions but they do get entered by members who find them in a shop & breed them, later distributing them to members (in good faith) as Akure. I have inserted photos of these four populations for comparison. Do not attach a different population just on these photos. If you are not sure just exactly what they are don't put a population against the name, just call them Fp. gardneri which will stop any inbreeding leading to the destruction of a population/line.
Website Only.... Marc Bellemans Nothobranchius site has recently moved to:- http://users.pandora.be/marc.bellemans/index.htm The Aquaristik website is worth looking at for it's archive of past journals. The address below will take you to the article on 'New fish from Amapa' concerning Rivulus. Some nice photos included. Written in German so the Babelfish translator mentioned a couple of issues ago will be useful here. http://www.aquaristik-online.de/Aktuell/1998/9-10-magazin-page18.html If you have trouble finding it go through the CNET search engine. For those interested in searching for latin names of species try http://www.calacademy.org/research/ichthyology/catalog/instr_spec.html which searches a species database. Just click SEARCH & then enter a genus or species you are looking for. For example riggenbachi comes up as a species of barb, anabantid & killie.
Oliver Legros has been busy with his site at http://home.tiscalinet.be/chromaphyosemion I have mentioned it in previous issues but recently paid the site a re-visit to find loads more photos & articles. These are written in French but you can translate them through Babelfish as mentioned last issue. If you have a backlog of TFH magazines & want to access past Journals try http://www.thekrib.com/Organizations/tfh.html
The CLOFFA website is useful in tracking down articles or authors http://126.96.36.199/powo/clof/ref/ref_0000.htm The new list of species of Chromaphyosemion in the AKA can be found here http://www.petsforum.com/tfsri/chromaph_list.html
Friedrich bitter has a good website at http://www.aquanet.de/autoframe.htm?url=http://www.aquanet.de/Chat/vortrag-killis/killi151198.htm This contains many good photos but the text is in German, so the Babelfish translator will be useful.
