Continuation.

In the second lecture on Friday Henrique Anatole spoke about "The IBAMA and its work in Brasil - about the problems to protect nature"





Henrique Anatole called the classification and duties of IBAMA in Brazil.
This involves, for example, by permission of hydroelectric power plants, oil platforms, highways, management of resources, ...
IBAMA is the only one of several institutions that are associated with the Brazilian Ministry of Environment.
This makes the work is not easy. Henrique: it is important not to argue, but to find solutions together.



A major problem of conservation in Brazil is very high biodiversity.
More than 20% of species on Earth are found in Brazil. Many of the species are undescribed (Thinking to the L-numbers).



There are several different biogeographic regions.
If we examines one of these major regions more precisely, there are again much smaller in it.
What is good for one biogeographic region, it must not be good for the other.



For the various natural resources, there are several possible uses.
For example, the catch of fish as a food fish, ornamental fish from the fishing, sport fishing ...
The rivers are needed for fishing but also for dams and industry.
There are different interest groups. This is difficult.
There are also other problems, such as:
If there create rules for use, they must also be monitored.
For example, several years ago the export of freshwater stingrays for a limited number were allowed again.
The government hoped to make money. The controls were much more expensive.
Often working in remote areas is needed - tens of kilometers far no shop, no bank, no school. It is difficult to find qualified employees for jobs in these areas.
Ultimately it cost to solve these problems a lot of money. It is helpful if people find with appropriate passion.
It seems important to educate people so that they respect nature.

In his lecture Henrique has shown us a very good variety of problems in Brazil, so that we understand a little better what is happening in Brazil in front of him.

The solution of the problem is certainly not child's play. It is important that people working to solve these problems.
Even if the path they have chosen does not match our expectations, we should show the necessary respect.

Hi,

Saturday, 05.11.2011

On the second day it was relatively early, start 9:00 clock.
For one or the other that was probably way too early. As I've been told, for example, is the only one went to bed by his roommate when the alarm rang to get up.



Jens Gottwald was charged with his presentation "L-catfish imports in Changing Times" wake up everyone.



As one of the German pioneers in the import of L-catfish he was not that difficult.



He recalled include the fact that in 1988 Baryancistrus sp. "L 18" (now Baryancistrus xanthellus ) 179 DEM and a [url="http://www. welsfans.de/index.php?art=110'] Pseudacanthicus sp. "L 25" [/url] 500 DEM cost.

The export of catfish from Brazil is linked essentially a history of positive lists and their implementation. Jens introduced us is the history of the lists, and discussed this.

Overview of the history of the positive lists:

Sep. 1989
Zebra pleco "L46" is presented in DATZ.

Ende 1989
Foundation of IBAMA

20.12.1989
1st positive list
45 species
DATZ presented to L51

14.03.1990
2nd positive list
79 species, 7 genus
DATZ presented to L62

1991
Hypancistrus zebra has been described scientifically (new genus, new species)

10.06.1992
3rd positive list
On position 178: Peckoltia sp. "zebra"

Dec. 2004
Hypancistrus zebra (L46) is added to the list of endangered species in Brazil

2005
4th positive list

Dec. 2008
5th positive list

(Nov. 2011?)
6th positive list

Hi,

The second lecture on Saturday was certainly the one that was most expected:
Henrique Anatole "The Future of the ornamental fish trade in Brasil".



To influence the ornamental fish trade in a meaningful way, one has during the last years in Brazil analyzed the current situation and take over places at which points can influence the IBAMA.



It was found, for example, that turnover has increased from 2006 to 2009 about 60% while the number of fish exported by about 40% decreased. The reason for this is that now, more and more fish are tightened. Thus, for example, the export of the Red Neon (Paracheirodon axelrodi) declined dramatically. The interest in armor catfish and rays has increased it.


Ornamental fish are caught primarily in the four states of Brasil: Amazonas, Roraima, Pará and Mato Grosso. These then are just a few small coastal areas. With the size of Brazil is therefore assumed that there are very many species which will be of interest as ornamental fish.

Were obtained from the analysis, as tasks were then derived the creation of an electronic control system and the revision of the positive list.
Since 2009, must decide on the positive list and the Ministry for Fisheries and Aquaculture (MPA). This delay reviewing the list considerably. The new positive list is expected to decided later this month. Henrique Anatole has recommended particular loricariids addition to the old list for the new list:



Hypancistrus inspector (L102)
Hypancistrus sp. "L 4"
Hypancistrus sp. "L 66"
Hypancistrus sp. "L 136"
Hypancistrus sp. "L 260"
Hypancistrus sp. "L 262"
Hypancistrus sp. "L 316"
Hypancistrus sp. "L 318"
Hypancistrus sp. "L 333"

Panaque armbrusteri (L27 Tapajos)

Panaqolus sp. "L 398"
Panaqolus sp. "L 271"

Pseudacanthicus sp. "L 24"
Pseudacanthicus sp. "L 25"
Pseudacanthicus sp. "L 79"
Pseudacanthicus sp. "L 97"
Pseudacanthicus sp. "L 185"
Pseudacanthicus sp. "L 273"
Pseudacanthicus sp. "L 320"
Pseudacanthicus spinosus

76 Corydoras
28 new Apistogramma

total 725 species
-----------------

Henrique is important that he now opposed to the old list knows exactly why a species is on the list or not.

Henrique Anatole notes that it will be the last positive list with undescribed species.

He is on the grounds that it is very important that these fish are known exactly. In Manaus, Sao Paulo, and yet a third location in each of the specimens were deposited on the positive list of related animals.
Furthermore, he promises himself that if the trade discovered a species to export, providing money to describe the species so that they can be approved.

(Here I have some doubts: Which dealer are several thousand real (2 BRL ~ 1 EUR) in order to describe then, after perhaps six years for exploration and description, not the kind that may be exported?)

Enrique Anatole further reported that the export of catfish is not governed solely by the positive list. For species that are not on the positive list, in limited quantities, it is possible to get his special permits.

Upon request, said Enrique Anatole, that if a species is on the positive list, will be renamed - for example, is thus assigned a different genre - automatically, without red tape on the then-current positive list should be renamed.



Further discussed Enrique Anatole asked whether it was better to get out of aquarium fish breeding than by extraction from natural habitats. Particularly with regard to the protection of the environment. It is the ornamental fish a very sparing use of the environment; whereas the scavengers are interested in the preservation of the environment as the fish grow, they need. Other alternatives in these regions are often only forestry and mining. Both are very bad for the environment.
An example of this is a project with arowanas.

What is important is always the consensus between all interested parties.
But especially the client (aquarists) determines the market that determines what fish are caught.

To be continued.

Hi,

if you are constantly listens attentively to the lectures, of course, must be provided for the meals...



and if there was still time, you could also go shopping. ;)



In the third lecture of the day tells us Christian Cramer, as it has drifted a few years ago to Brazil:
"The catfish due to Brazil - a doctoral thesis with consequences"



Christian had originally planed a project in terms of the Ancistrinae (now tribe Ancistrini).



After a dispute with J.W. Armbruster, he had his doctoral thesis, then decided to Hypoptopomatinae and [url="http://www.welsfans.de/index.php?db_unterfamilie=104&db_bilder=ja'] Neoplecostominae[/url].



Christian told us about his first experiences in Brazil and how it has evolved over the years, but settled in quite well there. Finally, he got married in Brazil and is now working on a project in Porto Velho.


Ingo Seidel informed about the sexual dimorphism in plecos in the fourth lecture of the day.



He found the following key differentiators

  1. size
  2. girth of body
  3. coloration
  4. head shape
  5. size and length of fins
  6. growth with odontodes
  7. growth with tentacle
  8. shape of the genital papilla
  9. shape of the teeth

Unfortunately, all these features do not meet all species, and if one of these criteria can be drawn from one species into consideration, the difference is not always clearly marked.
One should therefore not focus on a single feature, but the Individum as a whole look.



Ingo Seidel explains, for example, how to Hypancistrus sp. "L 333" can distinguish the gender of the head shape.



Another example: The gender difference in Lasiancistrus saetiger (L322) is demonstrated by the growth of odontodes. Ingo shows you have on what to look.

It should be mentioned that Ingo distinction between the sexes on the basis of the genital papilla looks to be very difficult. Other features there are usually more obvious.

Hi,

One of the main themes of this year's L-Number-Days were the cactus plecos, the Pseudacanthicus.
With the exception of Pseudacanthicus leopardus should not be exported valid cactus plecos from Brazil. It should be noted that in Brazil is not distinguishable between Pseudacanthicus leopardus and Pseudacanthicus sp. "L 114".

Ingo Seidel opened the lecture block with the Overview of "The genus Pseudacanthicus".



First, Ingo Seidel went to the classification of Pseudacanthicus.
Armbruster has the Pseudacanthicus together with the genera
  • Acanthicus
  • Leporacanthicus
  • Megalancistrus
put together in the Acanthicus group.

Ingo divides Pseudacanthicus themselves into four groups:




The distinction between the sexes was another key point in Ingo's lecture.



Ingo recommends for stimulation:
  • temperature change
  • Lowering the pH
  • additional flow
  • large water change with slightly cooler water

Other points of Ingos lecture were raise offspring, the incidence of Pseudacanthicus in South America, etc.

In the 6th lecture of Saturday Volker Degutsch reported on his successful breedings of Pseudacanthicus leopardus and Pseudacanthicus sp. "Alenquer".

Udo Wannig then reported in his lecture "Care and breeding of Pseudacanthicus sp." about his experience, gained at the offspring of Pseudacanthicus sp. "L 114" and Pseudacanthicus sp. "L 97".






In cactus plecos, it is also hot over here, so that hurt the animals. Good to know, how can we treat open wounds (certainly not only) Pseudacanthicus. John Leuenberger from Basel Zoo explained the basics and the implementation of the "Wound treatment for large catfish on the example of Pseudacanthicus sp. (L 25)."



Of the Koi a "two-component glue" for the treatment of large, open wounds is known:




The speakers, thanks for lectures:





Geoff Haglund came from New Zealand..

As a small surprise, there was an addition of Jens Gottwald. He had returned only a few days earlier from French Guyana.






In French Guiana Jens Gottwald caught Pseudacanthicus fordii f.e. .

French Guiana is Europe's fishing buddies especially interesting because, it's a "country" of France and thus belong to the EU.

To be continued.

Hi,

Sorry for the long break.

SUNDAY, Nov. 06th, 2011

Christian Cramer opened the conference day with "On the trail of unusual loricariids through Brazil"



First Chrisitian explained the different methods of fishing, which they use for their research work:
  • frame net
  • drag net
  • gill net
  • cast net
  • trawl



Then Christian told us pictures of his trips to Brazil. He showed us many pictures of habitats



and plecos



The participants listened attentively to the lectures:




In the second lecture of the day it came to "Breeding Hypancistrus species".



Erlend Bertelsen collected many data from Norwegian pleco holders.



I found it very impressive, how active they are in Norway in breeding plecos.


Then it was slate gray on the screen.



Sandor Tüllmann told us his experiences at the "Breeding of zombie plecos (L70) ".



The breeding of Hypanicistrus sp. "L 70" is not difficult.
This species/form of Hypancistrus is not attractive. Therefore L 70 very rarely kept in European aquariums.
It is important, that Sandor has accepted this task for conservation of the species/form in our aquariums.

Not all very nice, interesting plecos have an L-number.
In Hans-Georg Evers lecture "Without L and still beautiful: Hisonotus aky" there he introduced us a representative.



Especially the green color catches our eyes.



Hans tells us about the habitats and how he could use this information to breed these species.
A temperature at 22 ° C and strong water changes were obviously the key to success.


We know better the sun plecos Scobinancistrus aureatus (L 14).

In Catfish Atlas 2 Seidel/Evers was already reported a breeding of these species. Rajanta Sinardja Rahardj talk about " Successful breeding of sun catfish L 14 (Scobinancistrus aureatus) in Indonesia ".



First, Rajanta Sinardja Rahardja reported on his fish farm. Speaks for itself: f. e. the production of about 200 Hypancistrus zebra (L 46) per month.

Rajanta Sinardja Rahardja then introduced us to the sun plecos in some details.
Appeared particularly interesting that he keeps his species in complete darkness - except for a little time to care.




Andreas Tanke were finally have a " Overview of important accessories for breeding plecos"



Andi has obviously taken a lot of time to examine the various accessories for plecos from caves to breeding pools accurate and introduce ourselves.



The end was near:




A big thank to the organizers Andi and Ingo (right) and all helpers.



Thanks also to the donors and sponsors of the 2nd International L-Number-Days and the IG BSSW eV , without which the event would not have been possible.

We certainly see again in two years to the 3rd International L-Number-Days.

That's all.
