Abstract
On the 1980's Madonna used to sing that "We are living in a material world". Today, when we are deep into the 21st century, we know that we are living in a "data driven world". Our industry of aquaculture is a unique industry amongst the other agricultural sectors, from many reasons. But the main reason to that is due to the fact that when a fish grower leaves the farm at the end of the day, he knows exactly how much money he spent on feed, on labor, fuel, energy etc., but unlike diary, or poultry for example, where one can actually see what he grows, count the animals, see how they were fatten, here a farmer doesn't know how much money he made (or, to be more precise - how much biomass he added to the live biomass of the farm). No counting is possible, nor vision of all the stock.
