July 27, 2007 Frances' Cove, sunny, windless.
As I remember, we did some practice seines at Frances' Cove, and did gastric lavage on some juvenile chinook. This was documented on the old site.
In the first seine at 15:30, we caught
1 kelp crab,
3 shiner perches from 110 - 115 mm
1 striped perch at 126 mm
1 Sharpnose Sculpin at 58 mm.
We also did gastric lavage on 12 wild juvenile chinook, from 69 - 106 mm. We were surprised and delighted to find that individual fish had very different preferences. A 103 mm chinook had a 60 mm sand lance in its stomach. The 104 mm fish had mysid shrimps. Other fish had eaten nothing but black dots, green blobs, or pink gunk. We wanted to know if fish chose different diets because they came from different natal streams, or if it was something else. I don't believe we ever found out where these fish originally came from.
We did a second seine at 17:25, and caught
1 kelp crab
1 Lion's Mane Jelly
2 Staghorn Sculpins
We also caught 3 juvenile chinooks from 90 - 116 mm. The 113 mm one had gill parasites, the 116 one had a 64 mm Sand Lance in its stomach.
We did a third tow and caught
1 Cabezon, 240 mm
1 flatfish spp, 31 mm
4 Staghorn Sculpins from 60 - 85 mm
3 Chinook Salmon from 78 - 112 mm
red rock crabs, dungness crabs.
