Counting For 2009 Is Over!

With almost all zeros for the last two days, we've ended the counting for 2009.

We're deeply indebted to all of our counters - we did over 450 counts and missed only a couple - great work by all involved!!

We'll publish the details of the count in our next Newsletter. Join our Emailing list at the link at the right to receive it.

Note: All of the counters are automatically on this list, no need to join again.

Watching The Counting Results Closely

We're racking up a mostly zeros now and if this goes on for another day or two, we'll call it quits.

We're now in the 25th Day of the Run this year, and as posted earlier, we ended in prior years as follows:
  • 2008 - Day 36
  • 2007 - Day 23
  • 2006 - Day 27
2008 was by far the biggest Run we've recorded - in both volume and duration, so realizing that 2009 won't be anything like 2008, the years 2007 and 2006 suggest we're about done.

Depends Upon How You Look At It...

While my last post lamented over the sudden drop-off in counts, there is a bright side to the numbers!

If you click on the "schedules and counts" link at the right, then on the "MillPond.YearToYear" tab, you'll see that the 2009 "Run Cumulative Count" for day 19 [the last completely counted day as of this writing] was 1,288 Herring.

Compared to 2008 [4,577], that's not very good - a drop of 3,289 Herring counted, or -72%. BUT, compared to 2006 [481] it's a increase of 807 Herring counted or +167% - and that's great news!

Why? Because the Herring returning in 2009 have nothing to do with the Herring that were here in 2008 and 2007. Herring are at least 3 years old before they reach maturity and return to spawn, meaning that the Herring in the 2009 migration are the offspring of those in the 2006 migration.

Granted, some of those returning in 2009 may be 4 years old [and older], but almost all of my research puts the return at 3 years of age. So, we should be pleased that the 2006 offspring are returning in significantly higher numbers!

Separately, we're monitoring the counts very closely now, as we'll try to end the counting as soon as it looks like the migration is over, so as to not waste our counter's time.

But a look at 2006 shows 2 surges after some very low counts. And, perhaps we stopped just a little too soon in 2008.

We know that many of our counters are ringing in zeros right now, but if we didn't count them, we wouldn't know they were zero - and knowing it's zero is equally as important as knowing it was, say 100.

Disappointing Counts...

The bottom has fallen out of the numbers at Mill Pond starting Wednesday 04-29 through Sunday 05-03.

While there are a couple of counts not yet posted, most of the above days have less then 10 Herring counted for the entire day [that's just what we count, not what the total number of Herring for these days].

Don't know if there will be a second wind, as in prior years, but we'll keep counting for awhile yet.

We're now in Day 18 of the Run this year and the Run ended in prior years as follows:
  • 2008 - Day 36
  • 2007 - Day 23
  • 2006 - Day 27
But interestingly, on Day 18 of prior years, here's what Percent Complete the Run was:
  • 2008 - 87%
  • 2007 - 92%
  • 2006 - 64%
We have completed the counts through Day 14 of this year with a total of 1,242 Herring counted. In prior years the number counted through Day 14 were as follows:
  • 2008 - 3,787
  • 2007 - 1,448
  • 2006 - 400
