9月14日 ASHLU PINKSSquamish Streamkeepers Update September 12/09
Ashlu Channels Pink Salmon counts-Final Totals for 2009
All channels were counted to compare with previous mid-Sept counts. With high and silty water only live and dead fish seen were counted which means many in deep pools went uncounted. Since the same conditions existed during previous years counts the missing fish need not be allowed for. As in previous years, the first wave of pinks has spawned and died and the second wave is now spawning. Only the Ashlu Channels were counted, not the Ashlu River.

-On Sept 12/09 Grizzly Channel had 29 pinks and Volunteer Channel 1674 but these weren’t included
In our assessment today as these channels weren’t counted in previous years.
The pinks have spread out quite evenly through the many channels, some of which were just dug this year. They find the gravel with the appropriate flow and dig up a nest. This tail powered excavation is steadily expanding the amount of gravel available to other salmon as well as putting important nutrients into the stream.
Assuming that half of the 6,000 spawners are females and they carry 2,000 eggs that would put 6 million eggs in the gravel. With the good gravel and if flow is maintained, there should be a few million pink fry heading to sea next Spring. 引用通告此日志的引用通告 URL 是： http://dpixd.spaces.live.com/blog/cns!46CEF61CE1A73B95!5750.trak 引用此项的网络日志
