The years selected are 2009 to 2012, the query used in the report_ge_weight-class loads from 2008-08-01 to 2012-08-01 Glass eel are too numerous to be counted. They are weighted and in the stacomi database, a table with daily coefficients (in N glass eel/g) to transform weight into number. The weight is called a "wet weight" as we don't wan't to drain any of the mucus in glass eel when weighting them.
