The data gathered in this database are very diverse, they concerned different BQE and physico chemical analyses. Different organisms collected these data from different protocols. Concerning the fish dB, the lakes are sampled on different GPS referenced points (different net settled for one lake). Fish sampling are connected to a particular campaign, identified by a beginning and a ending date, as well as all the physico chemical data available (thermo depth, oxycline depth, air temperature, secchi disk...)(as much as we can). All net settled during a campaign are described: CEN standard or not, stratum of the net, hour settlement, hour taking off...)and the fished catched are gathered in different type of lot (individual, batch of fish) with measurement and weight where possible(sex if possible).
