Visit to prof. Asturiano

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?

Counting chamber with squares of different size

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!
