Elemental concentrations in fishes from the Salton Sea, Southeastern California

Detailed study of water quality, bottom sediment, and biota associated with irrigation drainage in the Salton Sea area, California, 1988-90

“…However, the threshold concentration in tissues at which selenium is toxic to saltwater fish remains unknown. Boron concentrations in fish sampled by Saiki (1990) were comparable to those reported by Setmire and others (1990). Cooke and Bruland (1987) and McCleneghan and others (1981) studied the occurrence and distribution of inorganic and organic selenium species in the Kesterson Reservoir, San Joaquin River, and the Saiton Sea.…”

“…Excessive accumulation of selenium can seriously affect fish populations of the Saiton Sea (Saiki, 1990). For sensitive species, whole-body selenium concentrations greater than 12 ug/g dry weight may be sufficiently elevated to cause reproductive failure and deformities in embryos and young (Lemly and Smith, 1987).…”

“…Eccles (1979) reported 110 ug/kg DDE in bottom sediment at Trifolium Drain 1 in 1977, in comparison with 41 ug/kg in sediment collected for the reconnaissance study in 1986. Saiki (1990) collected a total of 21 composite samples of four species of fish from the Saiton Sea for analysis of trace-element concentrations. The species collected were orangemouth corvina (Cynoscion xanthulus), bairdiella (Bairdiella icistid), sargo (Anisotremus davidsoni), and Mozambique tilapia (Tilapia mossambicd).…”

Salton Sea ecosystem monitoring and assessment plan

“…Where possible, sampling locations will include those currently sampled by the CDFW and USGS as part of their desert pupfish monitoring (for example, Keeney, 2009;Saiki andothers, 2008, 2010).…”

“…The USGS also has performed pupfish sampling in drains, ponds, creeks, and created saline impoundments in the Imperial Valley and Coachella Valley Saiki 2005, 2009;Saiki 1990;Saiki andothers 2008, 2011).…”
