Accounting system for red eel

The European Union calls upon all member states to evaluate their eel-management plans and thereby asks for a description of the proposed measures and the actually realized measures, and to what extent these measures contributed to the amount of sexually mature eels that escaped to the sea.

Also a number of specific estimates are requested. The most important estimates are the amount of sexually mature eels escaping to the sea 1) at this point, 2) in the historical situation when the state of the eel was optimal (The Netherlands also described this in the eel-management plan) and 3) if in the current situation, all man-induced mortality is avoided. The goal of this project is to design an accounting system to estimate the above mentioned requirements.
