Spring Census 2015 Parosphromenus-Project
Commentation of synopsis and godfathers
English: Interpretation of Synopsis (by Benjamin Wilden)
General:
In this spring census 58 members has send in a report.13 of these reported no Paros.
That was all in all a good participation.
It seems that still all species are present in our stock, although in varying numbers.
That brings us directly to a problem, which increased heavily since last year but in earlier years was seen very seldom: the reported fish have in many cases not been identified after purchase. That means in these cases the name which was used in trade has just simply been taken over. In a few cases the identification has been correct. In the harveyi group a correct determination is often not possible. In any case it is always good and interesting to know under which name the fish had been traded, specially if later on is planed an exchange with other breeders.
But there are many fish traded under the name P. deissneri or recently also under the name of P. gunawani. Especially this species had been seldom or never imported commercially yet. Therefore there is a need to be sceptical about the traders naming.
I can only register the fish which are reported to me in this way, as it is presented to me. Some holders are not quite sure about the species. That is o.k. We will think about this subject concerning the next census.
In particular because of the two mentioned species we must unfortunately assume that we were not able to sustain all species in our stock.
In general we can see that some very popular species as P. linkei, P. quindecim or P. nagyi are very frequently and constant in stock, while others like P. phoenicurus or P. cf. bintan by imports are very numerous. All other species are distributed between some few holders. These can sustain the species over some time and get enough offspring to give some away to others.
But many examples show us that P. filamentosus, specially P. cf. filamentosus spec. Ampah and also P. anjuganensis and many others, that a stock which once has been relatively numerous cannot be regarded as secured.
We thank all who have taken part in the Census.
Specifications:
P. alfredi is continually represented with few fish in stock. Also the offspring make us hopeful. Yet the species is bred by just a small numbers of holders, though very constant.
P. allani belongs to the critical species. The two location variations are only present at one friend each.
P. anjuganensis is an example for an shocking stock-reduction in the last two years. At that time these species belonged to the most numerous, now it has nearly disappeared.
P. bintan appears to be furthermore the most frequently held species.
The indicated sources however shows why – Fish from the P. bintan-harveyi group are relatively good commercially available.
Whether it really is P. bintan or not cannot be confirmed without location.
The situation is different in the locality forms. These can be found just at a few holders who however are holding the numbers of fish relatively constant.
P. deissneri seems to have disappeared from our stock.
Indeed this species had been reported by a holder, however it is unknown if this species had ever been imported by Ruinemans.
P. filamentosus furthermore is not as well represented as in recent years. However I would estimate the species as less endangered. Also for the variation „Ampah“ there are offspring who give hope.
P. gunawani is again poorly represented and also under serious threat.
P. harveyi was only reported by four holders. Although the numbers of fish are relatively high the stock is declining.
P. linkei is going on to be very secured. There have been reported many fish and offspring.
Yet the location forms can just be found at a few holders.
P. nagyi can be considered all in all as safe. However, inside the individual location groups can be observed a certain turnover, specially concerning the number of the holders.
P. opallios is going on to be poorly represented, the small number of fish as well as few holders point us to that the species is not safe.
Specially the location forms will die out shortly, because there are left only single fish.
P. ornaticauda is going on to be poorly represented and will probably furthermore rely on being imported.
P. pahuensis is going on to be very low in stock.
P. paludicola has just been reported by three holders, but that has always been so. Some offspring give hope.
P. parvolus also just had been reported by three holders. However they have relatively numerous fish and some offspring.
P. phoenicurus is going on to be good represented on the basis of the import of Aquarium Dietzenbach.
P. quindecim has remained stable. The species is frequent and can be considered as secured.
P. rubimontis also has remained stable. The species is not frequent but there have been reported some offspring.
P. sumatranus must be considered as critical. Just a few holders and no offspring.
P. tweedie remains to be represented reasonably well. There have been reported relatively numerous offspring at several holders.
