Mass marking of stocked European glass eels ( Anguilla anguilla) with alizarin red S
Abstract This study describes a mass marking method suitable for E uropean glass eel A nguilla anguilla , avoiding osmotic shock and reducing fish stress. During a single day, 360,000 glass eels intended for a stocking operation were bathed into an alizarin red S ( ARS ) solution, at a density of 34...
