Nowadays, the laboratory of Glasaal is located at Morseweg 7 in Volendam. On this location there have been many breakthroughs in the investigation, however the time has come to take a new direction. This hale restart will open new possibilities, aspirations and hopefully it will bring advancement in the investigation as well.
Before September 1st, the laboratory will be moved to Nijverheidsstraat 5U in Edam. This new location has a floor-area of 500 square meters, twice the size of our current location. This will result in a higher capacity for the investigation.
Regarding the food experiments, the new location is a huge improvement. Before, this phase of the investigation was a bit of a complication because of the lack of capacity. To give you an example, the following: in the current laboratory we had the possibility to examine three different kinds of food on the larvae and it took at least a month before any results came in.
Now, in the new laboratory it is possible to examine six kinds of food on the larvae and it will only take two weeks until the results will come in. A duplication of capacity. Furthermore, Glasaal will be able to keep more larvae and also keep them in a better way.

Glasaal Volendam has good contacts with the eel reproduction research groups around Europe. The collaboration between science and Glasaal Volendam helps us to acquire information about the eel reproduction cycle, without having to study it ourselves. This way we achieve eel reproduction in captivity earlier in time, we’ll make revenue sooner, and shareholders will receive dividend sooner at lower investments.
In the 2nd week of January, Camillo visited the Universitat Politècnica de València, Spain. At this university, the eel reproduction is studied as well. Where Glasaal Volendam encompasses the entire reproduction cycle with focus on larvae culture, UPV are experts when it comes to maturation of males. Camillo was welcomed by prof. dr. Juan Asturiano (find his blog here) in the brand new facilities of the university. Next to eel, other fish species like sea bass and sea bream can be found here.
to measure is to know…
Camillo learned how to establish the sperm density in milt, simply by counting how many cells can be found in what amount of water. Not a complicated method, but small deviations in the execution, can have big impact on the final calculation. And what to do with cells that are exactly on the lines of the grid?
Until now we’ve used our fertilization protocol to satisfaction for over 6 years. We’ve used a fixed amount of milt to fertilize a fixed amount of eggs. This new method allows us to neutralize natural variability in milt quality. Biologists of Glasaal Volendam are now better able to add the right amount of sperm to the right amount of eggs. This way we’re able to fertilize as many eggs as possible, and maintain high water quality the same time.
As you can read, scientists help Glasaal Volendam to advance in its process to achieve artificial reproduction of European eel. Ultimately, both nature and shareholders of Glasaal Volendam will benefit!

Eels play an important part of Japan’s food culture, with many restaurants serving grilled eel
Striking news about the Japanese eelt last month. Where we reported earlier about an increase of glass eel in the spring in European waters, for the first time in years, the news on the other side of the world is very different. “It’s clear that one swallow does not make a summer, and we must continue to work together for progress in the reproduction process to save the eel for the future,” according to Cees Zwarthoed, chairman of the board of Glasaal Volendam BV.
Japanese eels have now been classified as “endangered” owing to habitat loss, overfishing and other factors.
The freshwater eels, which are also called Unagi, were added to the International Endangered Species list in an apparent move to speed up industrial farming of the species. Japan is the largest consumer of eels, where they are commonly eaten as a roasted delicacy during the summer.
Rich in vitamins and minerals, Japanese eels are also used in Chinese medicine.
The International Union for Conservation of Nature said eel populations have declined by as much as 90% over the past 30 years. Other species of eel are also facing various levels of threat due to habitat damage and overfishing. “We must speed up efforts to build large-scale eel production systems,” said Japanese Agriculture Minister Yoshimasa Hayashi, adding that failure to do so would risk a very high extinction rate for the species.
Mr Hayashi also said he had little choice but to allow Japanese fishermen to continue catching baby eels for the time being. Efforts by the Japanese government to farm eels have made little progress due to the animals’ complicated migratory patterns of spawning in remote areas of the ocean.
Experts also said barriers along waterways, pollution and changes in ocean conditions were some factors responsible for dwindling eel numbers.
Bastien Debeuf of Glasaal Volendam will participate in the “Eel Genome Symposium 2014” on 16 and 17 january 2014 in Leiden.
Scientists from all over the world gather to exchange their works on eel genome
