Com­men­ta­tion of syn­op­sis and god­fa­thers (by Ben­jamin Wilden)

Gen­eral remarks:

In this year´s autumn Cen­sus 37 persons.have taken part
Two of them have been reports of hav­ing ‚no fish’.
This is an over­all low level of participation.


It should be noted, that in the spring Cen­sus we had 13 reports of hav­ing ‚no fish’ (of 57 par­tic­i­pants).
In addi­tion to this, I wasn’t able this time to send as many remind­ing emails as last year to indi­vid­ual members.

All species are still in stock, but in a very dif­fer­ent distribution.


In com­par­i­son with the spring cen­sus, there should not be much changed, if we assume that the stock of the par­tic­i­pants who took part in spring but didn’t par­tic­i­pate now, isn’t mod­i­fied much now,

Exam­ples of this are P.filamentosus and in par­tic­u­lar its vari­a­tion sp.Ampah.

Spe­cially P.deissneri, P.sumatranus, P.gunavani, P.allani and P.parvulus are again weak in num­bers. Addi­tional there are the species of P.rubimontis and P.opallios which is only rep­re­sented by a few ani­mals and few breed­ers.

Again in a good con­di­tion is the stock of P.bintan, P.filamentosus, P.linkei, P.nagyi, P.quindecim and P.tweedie.

A very impor­tant event for us has of course been the import of P.phoenicurus. This species can be con­sid­ered as secured in stock for the moment.

Con­cern­ing the god­fa­thers, I have marked as usual the not par­tic­i­pants with (?) and the new engaged with (NEW).

I think it goes with­out say­ing that spe­cially those friends who are the only per­sons who main­tain a species or a vari­ety, have a spe­cial respon­si­bil­ity for the con­tin­ued exis­tence of the species or vari­ety and don´t need to be nom­i­nated explic­itly as god­fa­thers (unless they have been already the godfathers).

Spe­cial remarks:

At this point I want to apol­o­gize for some mis­takes I had made with the spring cen­sus.
There was a update of the mail sys­tem of the P.-P. coin­cid­ing with a change of the cen­sus lay­out made by me.
Also this time the lay­out has been a lit­tle bit adapted for a bet­ter read­abil­ity.
If you find a mis­take in spite of my con­trols, tell me and I will cor­rect it.

Now I think the sys­tem runs and will not need any adap­tions for the next census.

Fur­ther more I would like to once again say that it is very good to note all infor­ma­tion which is avail­able of your fish, — their ori­gin, import, and how they have been recorded in ear­lier Cen­sus. Some par­tic­i­pants have already done this in the present and in the pre­vi­ous Cen­sus, — and this enables us to track the fish bet­ter and in par­tic­u­lar it enables us to see where the off­spring is recorded and found.

There has been a dis­cus­sion in the forum con­cern­ing this. This dis­cus­sion cen­tered around the ques­tion if we need to iden­tify exactly our fish which comes to us via trade. It is with­out doubt very nice to be able to iden­tify our fish excatly. In almost all cases this is also quite pos­si­ble and it is an explicit con­di­tion for our Cen­sus. It should be pos­si­ble for every­body to dis­tin­quish a P. deiss­neri from other parosphromenus species through the help of photos.

In this present Cen­sus I am not sure that this has been done by every­body. who reported deiss­neri.. I am how­ever not able to eval­u­ate this and change to another species accord­ing to what I might think.

I would there­fore ask that you con­tact experts for iden­ti­fi­ca­tion for exam­ple in the forum, in par­tic­u­lar if you have uniden­ti­fied fish from trade.

On the other hand it is in par­tic­u­lar also in these cases very impor­tant, that the infor­ma­tion of trade and if pos­si­ble also the date of pur­chase (year) of the fish is noted.

But with other species it may not be so easy. The P. bin­tan group is even for experts dif­fi­cult. For this group infor­ma­tion about ori­gin and details of how and where they were pur­chased is impor­tant for clas­si­fi­ca­tion and distin­guish­ing, in order that com­pletely dif­fer­ent species, which has been traded under the same name, and iden­ti­fi­ca­tion should not later be mixed with others.

We would like to thank all of you who have taken part in the census.
