Aquaculture and eel

Trade journal Nature and Science and Nobel prize winner Peter Drucker have been saying it for years: in the next ten years aquaculture will cause an even larger revolution than the internet and is the most promising opportunity for investment of the 21st century.

About 99% of all fish species will be over caught, because catches are already declining while the demand steadily increases. This will cause a gap that will have to be filled by aquaculture. This is the process of keeping fish in a pond or basin with the ultimate goal of selling it.

Fish farms have already successfully started breeding fish such as salmon where up to 80% of the fish are reproduced following the new breeding method. Eel farmers have not yet been able to level this feat however the Japanese have come close over the years.

Lifecycle of the eel
The eel, also known as the European eel (Anguilla Anguilla) is a ray-finned fish that belongs to the eel family (Anguillidae). The eel exists in large parts of Europe and North-Africa and resides in muddy waters. The eel that can be found in Holland and large parts of Europe and North-Africa is actually called the European eel. Examples of strongly related eels are the American eel and the Japanese eel.

Ever since the Roman era humans have studied the eel, but yet no-one knows its exact birthplace and how it develops into the eel that can be found in fresh water lakes such as the Ijsselmeer. The Dane Schmidt discovered the smallest glass eel larva yet that he followed through the Sargasso Sea. This is the place that we assume the eel is born.

During the journey it makes the glass eel larva develops into the glass eel. Arrived at the coasts of Europe and inland waters such the Ijsselmeer, the glass eel has developed into the eel. It is here that the eel develops into the silver eel that is ready for reproduction. The silvereel then makes the journey back to the Sargasso Sea where it spawns (more than a million eggs at a time, twice). After this the eel dies and the lifecycle begins again.
