This
workshop was preceded by otolith exchanges in 2011 and 2013, which were
undertaken using WebGR.
The
workshop achieved quite a lot in terms of ironing out, through discussion and
calibration, some of the major difficulties in ageing otoliths of sea bass.
This group recommend use of scales for sea bass ageing. For future exchanges,
it would be beneficial to compare unstained otolith sections with transmitted
and reflected lights and stained otolith sections, with the scales. For scale
exchanges, the group recommend the use of multiple scale images (or videos) for
each fish. The group reached agreement on a definition of an ageing guideline
and a reference collection presented in this report and the aim is to employ
these tools for all laboratories.
