2nd International L-Number Days, Hannover 2011 After a long journey from Jakarta to Hannover, my wife, Juliawati and I arrived on Wednesday 2nd November 2011 at Ramada Hotel where the 2nd International L-number Days convention took place. On the day of the convention, we met some great people who shared their years of experiences in the ornamental fish industry. One of the persons was Mr. Lars Andersen who came from Sweden with his wife for the meeting. He shared his experiences in taking care of Tropheus species. Yes, you are right, what is a Tanganyikan cichlid expert doing in the pleco convention? Well. I guess there is no boundary for fish hobbyists to enjoy the beauty of different fish. We also met with Mr. Steve Lundblad from Cichlids Exchange and Mr. Stephen Tanner (Swiss Tropical) who came all the way from the USA. On the first day after being opened by Mr. Ingo Seidel and Mr. Andreas Tanke, we learned an interesting information about the habitats of different kind of plecos in the Amazon. Mr. Hans-Georg Evers shared his knowledge about the Biotopes of L-Numbers in Amazonia. He shared his interesting idea from his field experience about the possibility of migratory behavior of the adult plecos to a certain area in the river to mate and lay eggs. Mr. Henrique Anatole, as the second speaker, shared how the IBAMA works to balance the need to protect the Brazilian natural resources while at the same time give the people the chance to get incomes from nature itself. On the second day, we have got a new hope from Mr. Anatole about the possibility that the IBAMA will have new positive list in the very new future. Some of the fish in the list were: L273, 260 and many more beautiful plecos that were banned before. Many of the people in the convention believed that this would create more excitements on ornamental fish market. Another interesting topic about 'Sexual dimorphisms of L-Number' brought by Mr. Seidel was another excellent insights for us. We could also learned from Mr. Volker Degutsch and Mr. Udo Wanniger about their experience in breeding Pseudacanthicus species. The last but not the list, we could learned about the treatment of wouds of large plecos brought by Mr. Johannes Leuenberger. The talk was an interesting one because he shared his experiences in treating large L 25 (Scarlet Pleco) using the method that is commonly used by the Koi breeder. On the final day, the talks were opened by Mr. Christian Cramer from Germany who talked about his experience in finding the unusual loricariids in Brazil. We could also learn about the experience of breeding some Hypancistrus species brought by Mr. Erlend Bertelsen from Norwegia and Mr. Sandor Tullmann from Germany. After the talk by Mr. Evers about breeding Hisonotus aky, it was time for me to share my experience in breeding L14 (Sunshine Pleco) in Indonesia. It was a valuable experience for me because I can share my experience with other pleco experts in the world. Thanks Hans for the translations and the support. The closing of the talks was ended by the talk by Mr. Tanke from Germany who talked about the importance accessories for the breeding of L-number catfish. Finally, the most anticipated seminar by pleco enthusiast all over the world came to an end. We have learned a lot and met with great people in the industry. Last but not least, I also would like to thank Mr. Irwin Phuah (Pleco Club) from Singapore who introduced me to Mr. Julian Dignall (Planet Catfish owner). I think it is a great opportunity for catfish enthusiasts to join this meeting and meet with people who share the same passion for catfishes. My wife and I hope that we can attend the meeting again in 2013.
