AbstractIntermittent chlorination to inhibit biofouling in condensers is a widespread practice in the power generation industry. Because the U.S. Environmental Protection Agency's water quality criteria for chlorine were based on continuous chlorine exposure of test organisms, it is possible that effluent discharge limits derived from these criteria ...

Two atherinid species, Labidesthes sicculus (brook silverside) and Menidia beryllina (inland silverside), often co-occur in North American reservoirs. Menidia beryllina is a superior competitor for zooplankton and has displaced Labidesthes in a number of reservoir habitats.

Journal of Fish Biology, 1999
The annual atherinid fishes, Menidia menidia and M. beryllina, are extremely similar morphologically, but appear to differ in their energetics and life histories. They emerge from winter in relatively emaciated condition. Menidia menidia males and females showed little change in carcass weight but significant increases in gonad weight in March and ...

Stormwater runoff in a coastal urban area (San Diego County, CA) produced significant toxicity to early life stages of medaka (Oryzias latipes) and Menidia (M. beryllina). Exposure of embryos to lower concentrations (5 to 25%) increased the incidence of abnormal swim bladder inflation and other teratogenic responses, whereas higher concentrations ...

Aquatic Toxicology, 2015
Exposure of fish embryos to relatively low concentrations of oil has been implicated in sub-lethal toxicity. The objective of this study was to determine the effects of the exposure of Menidia beryllina embryos at 30-48h post-fertilization to the water accommodated fractions of oil (WAF, 200ppm, v/v), dispersants (20ppm, v/v, Corexit 9500 or 9527), and

Abstract Postlarvae of two atherinid species, Menidia menidia (L.) and Menidia beryllina (Cope), were tested in two 14-day experiments at four densities of fish to determine effects of interspecific versus intraspecific competition for food. In one experiment, when M. menidia was slightly larger than M.

Abstract Larval topsmelt (Atherinops affinis) and inland silversides (Menidia beryllina) were exposed in 96-h static acute toxicity tests to 11 chemicals to determine the relative sensitivity of the two atherinid species. High to low LC50 ratios for endosulfan, methoxychlor, carbophenothion, chlorpyrifos, terbufos, fenvalerate ...

ABSTRACT Larvae of the inland silverside Menidia beryllina (Atherinidae) were observed in a chamber with two horizontal water layers to study their aversive response to hypoxia. When larvae descended from an upper normoxic layer into a lower hypoxic layer, they displayed a characteristic avoidance reaction consisting of a burst of fast ...
