Now-a-days Red river hogs are a normal sight in European zoos but this has not always been the case. Till the mid-1960-ties wild-caught animals came now and then from Africa but breeding was rare and afterr a while these animals died. In 1975 a small piglet was discovered on a banana-ship in Rotterdam-harbour and was in a bad shape. The animal was given to a Dutch animal-dealer and he contacted Duisburg Zoo. Because it was even in those days already illigal to transport ( wild ) pigs from one country to another, the animal was brought under the name "Red trunk-hustler" to Duisburg and here the little male recovered. Through some contacts which Duisburg Zoo had with Togo - from where the first male came - it was possible to import legaly a female in 1977 and already a year later the German first breeding took place at Duisburg. Zootierliste mentions that Duisburg obtained that same year ( 1978 ) a captive-bred male from La Palmyre in France but the same Zootierliste don't mention La Palmyre both on it's current or former keepers of the species so .... any ZooChatter with more information about this ? Duisburg had very good breeding-results with the species and they were send to a number of other European zoos. New blood into this population was brougth in by an animal from Frankfurt Zoo ( don't know in which year this animal was brought into the population ) and an animal from Paris which was wild-caught in Guinea and was send from Paris to Duisburg in 1987. In 2011 Duisburg recieved a group of 4 animals ( sexes not mentioned ) from San Diego. All the above information means that ( untill 2011 ) all Red river hogs in Europe have a founder-population of - at its hightst - 4 animals ! Would be intresting to know if the San Diego-animals have already some impact on the European population and what was with the captive-bred animal from La Palmyre.
