1. Scale Reading Practical
The first section of slides show
actual examples of scales from

Clue: Caught in August but
look at the Erosion
There are two definite winters –but what next? The plus growth after the
second Winter seems to be heavily closing but Summer fish should be
“Open” at the edges. The erosion shows however that this fish came in a
long time before August. The most likely explanation is that this is a very
small, 3SW Springer. Again, not all 3SW fish are large
?
