Stickleback collecting - Riverbend Oregon, June 2011

Riverbend, Oregon. It was a beautiful day.


The mighty stickleback hunters!





Part of the collection.

Sculpin Fry

They are really small and hard to see but if you look close they are the long pieces of rice that don't act like bubbles but go up and down in the water column.

Tide pool sculpin having lunch

Sculpin eating frozen mysid shrimp. They really go after them!

Sculpin embryos

First clutch of embryos. The yolks are a very beautiful shade of purple. The embryos were removed placed into their own tank within a glass dish. The dish was placed in the flow of water for aeration.

Tidepool sculpin

These tidepool sculpin were collected near Coosbay, Oregon and added to the system on 2/14/11. There appears to be 3 large females and many males. The females were split into two tanks along with the males. We hope to get embryos for juvenile studies.

Old stickleback-oikoplura filter resurrected to grow sculpin

A little plumbing and addition of a pump and this old system is running again. The balls (already in place) in the sump are meant as a baffle to cut down on the salty aerosols.
