Possible Lectures & Seminars

Image Heiko Bleher has an almost endless selection for possible lectures and seminars, what the topic fresh and brackish water is concerned, as it has been with him his entire life – and in the 3rd. generation.  

He can give a seminar of anyone of the order of Pisces, their family, or just of a single genus or species, as well as on aquatic plant (his grandfather is still considered to be the “father of aquatic plants”). Many of his seminars concern their natural habitat (which he researched in more than 160 countries), or their nutrition in nature and in the aquarium. Heiko lectures about fish diseases and treatments (from his more than 40 years of practical experience with millions of fishes he yearly imported, treated and sold to 86 countries – more than 5000 different aquarium fish species).

But his lectures are not limited to fishes and aquatic plants, but also to the actual status of the environment around the globe and the effects of global warming. In his archive of more than two million photos he holds probably the most extensive record of the destruction of tropical rain forests in all countries – past and present. He can talk about the useless construction of hydroelectric dams and show the consequences in nature, its flora and fauna, if that is in countries like Ghana, Mali, Brazil, if in Laos, China, Colombia or India – to name just a few. And Heiko has the most unique and up-dated record of the destruction of freshwater habitats worldwide – our most precious resources overlooked by many – including a record of all exotic introductions. He can document facts, which probably no media-report has ever captured, shown or recorded.

Most of the lectures and seminars Heiko has given around the world – in more than 80 countries – were about nature, expeditions, new and/or re- discovered species. (Over 6000 – of which some bear his name – he has managed to introduce into the aquarium hobby and public aquaria worldwide.) But he also talks and shows the natural habitats of aquatic animals and plants in all continents, including the chemical water parameters.  

Heiko is also often asked to hold lectures and seminars on the development of the pet industry, past present and future – specially for the aquatic side of the industry. He lectures about the market share of fishes and their positive (as well as negative) influence, all over the world. His data book is full of statistics of the latter and being for three generations with the aquatic pet and plant business, gave him a unique feeling and prospective of its possibilities. He knows exactly its weak and strong points and how to succeed also in bad times. Many companies he consults and gives adequate advice for the future.

None of his lectures or his seminars he has presented twice, but if he is asked told hold them again, he will always update it to the newest discovery and knowledge…

Below one can find some of the above mentioned possible lectures and seminars – but not limited to – divided by categories. Each lecture or seminar lasts in average one hour – except for those mentioned otherwise:

1. Lectures by country

2. Lectures by expeditions/field trips and discoveries

3. Lectures and seminars by fish orders – families

4. Lectures and seminars on aquatic plants

5. Lectures and seminars for students, apprentice, retailers

    and wholesalers of live stock

6. Lectures and seminars on certain fish groups

7. Lectures on explorations in specific continents and/or recent new discoveries

8. Lectures and seminars on global warming, destruction of primary rain forests

    and possible improvements in each habitat/region/country



1. Lectures by country:


– For lectures by country please refere to the List of Expeditions and choose one

   of over 110 different ones were Heiko made extensive research in its aquatic

   habitats. But not only: he also recorded its people, their cultures and traditions

   (past & present), its flora and fauna today, the environment, the habitats, and

   also surveyed the man-made-destruction in detail as well as the global warming

   effects in each one.
