1 Gabriola Streamkeepers (GSK) Freshwater fish on Gabriola Island, BC Species (? = tentative id. * = introduced) threespine stickleback Gasterosteus aculeatus *pumpkinseeds Lepomis gibbosus staghorn sculpin Leptocottus armatus dace (peamouth chub) Mylocheilus caurinus? *cutthroat trout Oncorhynchus clarki lewisi chum salmon Oncorhynchus keta coho salmon Oncorhynchus kisutch *rainbow trout Oncorhynchus mykiss
2 Reports Castell Brook Coats Marsh Creek Commons Pond Descanso Creek Dick Brook Fiddlehead Creek Goodhue Creek old reports of fish being caught on rod and line, species unknown; sticklebacks in estuary (Sandwell Marsh, 2012, GSK); sticklebacks, sculpins, dace, chum fry (2014, GSK, photos); mature chum showing interest (2014, GSK, photo) but not observed in the creek. See also Sandwell Marsh and Lock Bay Beaver Pond. trout (2012, GSK). Hoggan Lake catchment area. sticklebacks (2009, Kinnears Commons survey, photo). On Goodhue Creek. old reports of sculpins (before the culvert went in?); sticklebacks (2012, GSK); pumpkinseeds (2014, GSK). unidentified freshwater fish, likely sticklebacks (2013, GSK); 100s of chum fry in intertidal and lower 30m of the stream, alevins (2014, GSK); chum jaw bone and vertebrae (2017, GSK, photo). unidentified anadromous species in freshwater above high tide (2013, GSK). old report of rainbow trout; sticklebacks (2012, confirmed); cutthroat trout (2014, GSK, photo); sticklebacks (2015, GSK). Hoggan Lake catchment area. Hoggan Lake stocked with rainbow trout and coastal cutthroat trout in 1924 and Both species observed in Angler reports catching rainbow trout in the 80s. (photos) No recent sightings in the lake, but trout seen in Coats Marsh Creek and cutthroat trout confirmed in Goodhue Creek downstream of South Road. The lake is also reported to contain sticklebacks that are quite like the benthic species of stickleback species pairs. Lock Bay Beaver Pond coastal cutthroat trout (2012, RAR survey, unconfirmed). Mallett Creek old report of cutthroat trout; juvenile coho (2013, GSK, photo); alevin chum or coho? (2014, GSK, photo); pumpkinseeds, mostly in the dugout (Peacocks Lake) but occasionally in pools downstream (2014, GSK, photo). Martin Brook sticklebacks in Bernards Pond. Peacocks Lake pumpkinseeds (2014, GSK, photo). On Mallett Creek. Sandwell Marsh see Castell Brook. This marsh is occasionally flooded by the sea. Wagg Brook cutthroat trout in estuary (2012, unconfirmed); pink salmon attempting to access (2012, unconfirmed); chum fry observed in freshwater above high tide (2013, GSK, photo); sticklebacks (2013, GSK).
3 Wagg Brook: chum fry These are most likely hatched from the Nanaimo river and have made their way over to Gabriola. Chum fry head out to sea immediately after hatching and seek estuaries and intertidal areas of streams for shelter. This fish was found in a freshwater pool just above the intertidal zone. [Jethro Baker, Apr. 26, 2013] Commons Pond: threespine stickleback [Kinnears, Jun. 8, 2009]
4 Mallett Creek: chum fry Chum still in its alevin stage. This fry was most certainly spawned in Mallett this past fall....we found it in the same pool low down in the intertidal section of the stream where we found fry last year but were then thinking that they may have travelled from the Nanaimo River. [Jethro Baker, Jan. 22, 2014] Goodhue Creek: cutthroat trout found in an isolated pool in Goodhue We released this little fish back and soon the pool will be part of the stream again and the trout will be able to make it back to Hoggan lake. [Jethro Baker, Sept. 23, 2014] Mallett Creek: juvenile coho found about a dozen juvenile salmon in several different pools in the creek. David Clough confirmed they were juvenile coho, a species that spend at least a year in a stream before migrating back out. [Jethro Baker, April 22, 2013]
![.. [Chris Hills, Nov. 1, 2014] Dick Brook: chum jawbone and other remains.](/docs-images/84/90666974/images/5-2.jpg "Possible this adult swam into the stream to attempt spawning and died or floated in on a high")
5 Castell Brook estuary: chum noticed this chum? hanging out right where the stream normally empties into Lock Bay! We watched it leave and circle but it always came back to the mouth of the stream. It looked spawned out. We were there for at least an hour and it stayed in the same area... [Chris Hills, Nov. 1, 2014] Dick Brook: chum jawbone and other remains. Possible this adult swam into the stream to attempt spawning and died or floated in on a high tide and an animal dragged it up the stream. About 200 ft. upstream of high tide. [Jethro Baker, Mar. 2, 2017]

6 Castell Brook Who says there are no fish in our streams? Castell upstream from the saltwater marsh (Sandwell Marsh). [Jethro Baker, March 17, 2014] Hoggan Lake As a kid, he (Rick) fished the lake. [Rick Mayes, 1982]
7 Castell Brook: Pacific staghorn sculpin. quite numerous in the saltwater marsh (Sandwell Marsh) and up into the stream. [Jethro Baker, March 16, 2014] Castell Brook: dace This is a rare fish as far as I know. I think it came into Sandwell Marsh on a freshwater film from another fresh waterway (Nanaimo?). I have never seen them since I took these. I first found them ( individuals) during high water early in the year. As the water level dropped so did their numbers until they were gone.
