V International Livebearer Weekend
3.-5. May 2013, Preikestolen Fjellstue, Stavanger, Norway
Speakers and presentations
Livebeares and Chiapas
Rune Evjeberg is from Stavanger in Norway. He is 35 years old. He has treveled several times to Mexico studying freshwater biotopes. His lecture will be a short introduction on the magnificent state of Chiapas, nature, biotopes and fish.
Speaker: Jan Huylebrouck, who among other scientific works have described the new species of halfbeaks, Nomorhamphus rex, will be speaker in the lecture on Livebearing Halfbeaks together with Ulrike Korte. His workplace is Alexander Koenig Museum, Bonn – the zoological museum of Bonn.
Speaker: Ulrike Korte, chairman of a german Halfbeak Study Group: "Livebearing Halfbeaks"
The lecture will be on the different genera of the family Hemirhamphidae ( livebearing halfbeaks ), especially life history and biology of the sister genera Dermogenys/Nomorhamphus and maintenance requirements of Nomorhamphus species in particular.
I would like to take the opportunity to promote our Hemirhamphidae study group and to present the work and findings within this group.
I am used to keeping fish since early childhood, as
my father's and my mother's family as well were active aquarists, so I grew up with keeping fish. Beside other aquaristic clubs, I am a member of the DGLZ and I do the judging during the annual exhibitions.
For instance, I have been safeguarding Nomorhamphus towoetii for about twelve years now.
Sexual conflict in the animal kingdom: How strategic female guppies avoid eager males
Speaker: Josefine Bohr Brask, PhD student at the Department of Biology, University of Copenhagen. Specialised in animal behaviour and evolution. Has participated in research in insects, mammals, and fish.
Outline of presentation:
The guppy has been a favourite species for studies in animal behaviour for half a century. One important aspect of animal behaviour that is currently being studied in the guppy is sexual conflict: In many species, males and females have different interests when it comes to reproduction, and this can lead to each sex developing strategies with which they attempt to get in control of reproduction. This talk will concern why the guppy is so popular among behavioural biologists, and how the fascinating behaviour of this species helps us understand sexual conflict in nature.
The GWG (Goodeid Working Group) and how to keep livebearers outdoors during summer in Europe
Speaker: Michael Köck, curator at ”Haus de Meeres, Aqua and Terra Zoo”, Vienna, Austria
I was born in 1968 under the signe of Capricorne, and traditionally, the Capricorne often is pictured with a fish tail. So my way breeding and keeping fish has been predetermined from the first minute and became a passion throughout the following years. In 1998 finally, I specialized in Goodeids.
After recognizing the critical situation of almost all Goodeid species in the wild, I decided to found a conservation group that became reality in 2009. Meanwhile, in 2005, I became curator in the Haus des Meeres, a zoo in the heart of Vienna, and the management of the zoo supported the Goodeid Working Group right from the beginning with space and funding. At the present, I am breeding more than 50 populations out of more than 30 species of Goodeids in more than 80 tanks in the zoo, among them rare species like Allotoca meeki and Allodontichthys polylepis.
My speech is composed out of two independent parts, but nevertheless interlinked by the demonstration of unsual ways in the field of maintaining livebearing fish.
The first part wants to describe the start and further steps in the developement and progress of the Goodeid Working Group, a working group founded in 2009 in response to the critical environmental issues facing the majority of wild Goodeid species, plus the poorly-documented ‘disappearance’ of many captive collections. A short overview of the goals and successes of the group will be given and a glance in the future shall be undertaken. It will be shown how international cooperation can achieve milestones in the conservation of endangered fish.
The second part will deal with an uncommon but proper way of keeping livebearing fish: Keeping them outdoors in summer. This way of breeding is accompanied by a lot of positive effects for both, fish and man (e.g. influence of UV-light, multiple food sources). Examples will be given what kind of species can be chosen for this kind of breeding, what facts shall be noted and where differences against tank breeding can be noticed. Outdoor summer keeping shall be introduced as a very interesting choice in fish husbandry full of surprises.
