Topic	Fish: Estuary Beach Trawl Sample Totals 1997

 

Caption:  This Chart shows the various species caught in the Russian River estuary using an otter trawl net at four sites from May to November 1997. The trawl operates near the bottom in the deepest part of the channel where it also tends to be salty. Prickly sculpin comprised 45 percent of the entire catch and were abundant at each station, as were they in 1996 (MSC, 1997). All species comprising more than 1% of the catch are common estuarine species in this region, except the Sacramento sucker. Suckers were captured at Station 3 because snags prevent sampling in the deepest part of the channel and the trawl is at a depth of 4-7 feet, which is above the salt wedge (MSC, 1998). Station 1 is nearest the ocean and Station 4 furthest upstream, but the salt wedge extends upstream in the deepest part of the channel (see Picture for map of sites). Data from Merritt Smith Consulting and Sonoma County. For more information, click on the InfoLinks tab.
