TWU (also my alma mater) established an Ecosystem Study Area around the university
https://www.twu.ca/environmental-studies/ecosystem-study-area. They take it pretty seriously.
The university also did electroshocking in June 2014. In two nights of activity, they netted 4520 fish of which 3039 bass and 1450 pumpkinseed sunfish were euthanized. This particular event was a partnership of the university's staff and students, Langley Environmental Partners Society, Salmon River Enhancement Society, and was also supported by a Community Salmon Program grant awarded by the Pacific Salmon Foundation.
The newsletter article went on to say "Andrew Tung...also examined the stomach contents, finding as expected that the larger-sized largemouth bass consumed large numbers of smaller fish. This predatory behavior is a critical reason why we are aiming to reduce their populations to reduce their impact on native fish in the Salmon River watershed. Andrew even discovered a mole in the stomach of one large fish! The legions of fish Andrew found in the stomachs of the bass served as a good reminder as to why we are going to all this effort!"
So why is the pond posted C&R when obviously there is great interest by the university and many community partners to reduce the number of invasive fish. I don't know but I bet there is a very good reason, because it obviously isn't to protect the bass.
Although part of the reason may lay in this quote. "TWU has a special permit to remove the fish, and as part of that permit you can not sell or trade them. And you probably wouldn't want to eat them either," says Erin Stoddard, Fisheries Biologist for the Ministry of Environment.
Christopher Hall is mentioned on the contact page of the TWU EAS. I bet he could provide some clarification behind that decision.
Side note about the pond from
https://www8.twu.ca/about/news/general/2008/twu-begins-invasive-species-fish-cull.htmlThe pond, or Trinity Lake as it is called, is not a natural body of water but was man-made years ago when TWU was first built. Used historically as a water reservoir in case of a campus fire, the pond was once much deeper and colder, and salmon entering it from the connected Salmon River flourished. Today the berm or raised edging around the pond is slowly collapsing and in one area, has collapsed completely, entirely closing off the pond to the Salmon River resulting in a pond which is higher in sediment and temperature, and has less flow to it. These changes have resulted in a perfect habitat for bass and other non-native fish species. "It's a good thing the pond is disconnected at this time but a major problem will occur in the winter when the banks of the pond overflow and invasive species enter the Salmon River ultimately destroying the salmon habitat. That is why we have to do the cull now to lessen this effect." says Hall.
