Review of previous

meetings on Baltic cod age reading: The

next comparative

cod age reading was organised in

accordance to C. Res. 1981 by H. Lassen.

Each laboratory was

asked to sample 50

otoliths.These otoliths were

circulated between the readers. The

ageing material was elaborated by

H.Lassen (ICES CM 1985/J:5).

WG - From WK 2009

report. In 1986 an

international working group consisting of

scientists from Greenland and Germany met four times to establish an

agreed reading protocol and

intercalibration. During the

fourth meeting, an overall

agree-ment > 80 % was

achieved by five readers, which was deemed sufficient

congruency by the group at

that time (Rätz 1989).

WK The results of the

1985 exchange scheme

prompted the convening of a second whiting

otolith Workshop held

in Dublin in May 1987. In

total there were 8

participants from England,

France, Ireland, the Netherlands and Northern Ireland. 633

whiting otoliths from the Irish Sea and 173 otoliths from

the Celtic Sea were read and

the results showed an

80% agreement

between pairs of readers for the Irish Sea

and 75% agreement for the Celtic sea. The workshop concluded that there was no evidence of systematic

errors and bias was not a serious

problem. Another way to

evaluate the precision of

otolith reading is to compare

individual readers

determinations with the modal

age i.e. the age

determined by the majority of the readers. Prior to the Hirtshals

Workshop the results from 198 Irish sea otoliths and

173 Celtic Sea otoliths were re-evaluated against the modal age

(Table 2.2.1 of the of 1998

WK report). It should be

noted that 2 of the readers

were classed as

“Occasional” and whilst their determinations were included in the analysis

there is no doubt that

excluding their results would

have increased the overall

level of precision. No

further work on the problems of whiting age determination in the North

Sea was undertaken until 1990

when a new otolith

exchange scheme was conducted by MAFF. 115

otoliths were read by 10 individual

readers from 7 institutes.

Table 2.2.2 of the of 1998 WK report

shows the % agreement

with the modal age for all

participants.

Ex See Section 2.2 of

1998 WK report: -

Review of Whiting Otolith

Exchanges and

Workshops. The next

chronological reference in the literature relates to an

Irish Sea/Celtic Sea whiting

otolith exchange in 1985. Four

institutes were involved in this

exchange - DANI

(Coleraine), FRC (Dublin),

IFREMER (Lorient) and

MAFF (Lowestoft). All

the otoliths were

transversely broken and two batches

were read, one of Irish Sea

otoliths and the other Celtic Sea otoliths. The results of the exchange showed a 54%

– 94% agreement

between pairs of institutes for the Irish Sea and 38% -

71% agreement for the Celtic Sea

otoliths.
