"It really damages the ability of the other partners and stakeholders who are trying to work together.". Delta Smelt, juvenile (swimming), UC Davis Fish Conservation and Culture Lab, Byron, CA (largely funded by the California Department of Water Resources) May 15, 2008. Given that we only trawled for 5 or 10 minutes at each locality, with a trawl-net dragged along the bottom (smelt are pelagic), it is a tribute to smelt abundance that enough were caught to make a meal.
This got me thinking about how badly we have managed the smelt’s pelagic habitat since that time. ( Log Out /

They were commonly captured in the otter trawls that we used monthly at multiple sampling stations. 1923. Copyright 2009 E&E Publishing. by Peter Moyle, Center for Watershed Sciences, UC Davis.

Yes, we have we have managed the smelt’s pelagic habitat very badly indeed, Dr. Moyle, mainly by continuing to withdraw increasing amounts of freshwater from the Delta.
Snow urged FWS to revisit water-storage restrictions at Oroville Dam, a crucial source of water, especially to farmers in the fertile San Joaquin Valley.

In spring smelt populations are dominated by spawning adults, and by summer they have died and given rise to the next generation of juveniles. Delta smelt grow quickly and the growth rate is largely food dependent.
Please note, watersheds are at the USGS 8-digit Hydrologic Unit Code (HUC) scale, so they often include a lot of sub-watersheds. "This population suggests that delta smelt are less susceptible to a catastrophic event than previously thought," Snow wrote in the letter to Ren Lohoefener, FWS's regional director in Sacramento.

Delta smelt are not the only likely victims to be claimed by California WaterFix—Delta environmental justice communities have significant numbers of individuals and families with incomes below the 2014 poverty line residing in Antioch, Pittsburg, Clarksburg, Stockton, Sacramento, and … Will we be able to return to sound management of Delta flows in order to restore salmon and smelt populations? Delicious. The most rapid growth occurs when they reach 30 mm FL and are large enough to prey on a wider variety of food sources. The two swim side by side and release eggs and milt, the male fish sometimes pausing to ward off other attending males.

She called Snow's petition "a peculiar attempt" to distance Indeed, a memorable experience from my high school days in Minnesota was driving up to the North Shore of Lake Superior with friends and spending a night dip-netting rainbow smelt in the freezing water. We built a fire on the beach and luxuriously fried the smelt in butter.
When I first started working on them, in the 1970s, they were abundant and frequently caught in various sampling programs. "There's no scientific basis for saying, 'Look at this again.'
The number of spawning fish is weakly or nominally associated with the number of the next generation. I am sad that I missed the opportunity to dine on delta and longfin smelt. In Swanson's view, the only logical explanation is that Snow wants to build support for construction of a peripheral canal around the delta to ensure water supplies are delivered to the south. Archaeological evidence suggests smelt were caught and eaten on occasion by the indigenous peoples of the region. Smelt are short burst swimmers that feed on plankton and therefore they are typically found in places with low water velocities where the water is cool and well oxygenated. Citing "new information," Snow told the U.S. "It's almost certainly political, because in fact it's not credible in terms of the science," Swanson said of the letter.
