Abstract

It is possible to mark octopus (Octopus vulgaris) paralarvae on a massive scale (up to 3500 paralarvae l−1) with 100% marking reliability using alizarin complexone (ALC). The whole statolith is marked and the best results obtained were with concentrations of 60-300 mg l−1 and bath duration of 3-24 h. Taking into account the quality of marking, mortality and ALC costs suggest using from 60 to 200 mg l−1 for 3-6 h. The only treatments causing significant mortalities were 300 mg l−1 over 6 and 24 h.
