June 2013 Hatchery Update

All the chum have been released into the wild. The second batch was taken over to Schoolhouse South and hopefully made their way downstream.

Now that both large tubs are free of fish, we’ve filled them with… TULIPS! We still have a lot of bulbs to sell, so make sure to drop in between 9-11 AM Monday to Saturday to pick some up at $5 a bag!

Last year’s coho are still growing in the cap troughs, and the ones from the year before are swimming around in the pond outside (which we will be releasing this month). Since we harvest coho eggs from Noons Creek whenever the adults are ready, each brood year contains a discrepancy in age groups. Although the separate cohorts only differ by a number of days, the older ones grow faster.

Even though these photos have motion blur (because living fish tend to move), one is clearly larger than the other. Both are from the 2012 brood year, but the smaller fish is what we call a 'pinhead'.

By the time they reach the smolt stage in their life cycle, some salmon are much bigger than others. Genetics also play a role, as some fish are predisposed to be more competitive and grow faster than others. A sample we took of the pond coho resulted in weights ranging from 8.4 – 32.6 grams. The heaviest fish weighed almost four times as much as the lightest one!
