Dies ist meistens nicht ganz korrekt! Wieder ist der Vergleich zum Menschen angebracht, der die Problematik offen legt: Als die Spanier um 1500 n. Chr. Südamerika eroberten, brachten sie die „harmlose“ Grippe mit.

Les détenteurs de bassin observent parfois que des poissons nouvellement introduits déclenchent une maladie et pensent alors que le vendeur leur a vendu des poissons malades. Ce n’est généralement pas le cas ! De nouveau, la comparaison avec l’homme est bien appropriée ici et traduit le problème posé : lorsque les Espagnols ont conquis l’Amérique du Sud, vers l’an 1500 de notre ère, ils ont apporté dans leurs bagages une grippe « anodine ». Les Amérindiens n’ayant encore jamais été exposés à ce virus grippal auparavant, ils n'avaient aucune défense immunitaire pour s'y opposer et sont morts par milliers. Il peut se passer le même genre de choses dans un bassin. Les nouveaux arrivants sont porteurs de quelques parasites anodins, contre lesquels ils se sont constitués une bonne capacité de résistance. Les poissons de votre bassin ne sont encore jamais entrés en contact avec ces agents pathogènes précis et sont donc très vulnérables. Il est donc plus que recommandé de renforcer le système immunitaire de vos poissons et même celui des nouveaux arrivants (le problème vaut dans les deux sens), avec JBL AccliPond .

Pond enthusiasts sometimes notice that new fish cause an outbreak of disease, and thus assume that the retailer has sold them diseased pond fish. This is not usually the case! Again a comparison with humans is appropriate to illustrate the problem. When the Spanish conquered South America in about 1500 AD, they introduced the “harmless” influenza virus. Since the natives of South America had never been exposed by these influenza viruses before, they hadn’t developed enough resistance to them and died in their thousands. It can be similar in the pond. The newly added fish have harmless parasites, which they have developed a resistance against. Your pond fish have never come in contact with these germs and are therefore very susceptible. Therefore a strengthening of your fish’s immune system and also of your new arrivals (the problem applies of course for both directions) is JBL AccliPond strongly recommended!
