Reproductive Timing Of The Scarlet Shiner (Lythrurus Fasciolaris) In Northern Alabama, Bruce Stallsmith, Toacca Taylor, Chelsie Smith
Southeastern Fishes Council Proceedings
The Scarlet Shiner (Lythrurus fasciolaris) is a cyprinid species widely distributed in parts of the Ohio, Cumberland and Tennessee river drainages of the United States. The objective of this study was to determine the Scarlet Shiner’s reproductive schedule. Maturation of ovaries and oocytes was determined through the categorization of developmental stages from early maturing to ripe, along with the calculation of monthly gonadosomatic index (GSI) measurements over two reproductive seasons in 2012 and 2015. In both years reproductive competence began in April. Average monthly GSI for females peaked in May, followed by a slow decline through August. Average clutch …

Salish Sea Ecosystem Conference
Green stormwater infrastructure (GSI) includes an evolving set of technologies to mitigate the physical and chemical habitat degradation that results from urban runoff entering aquatic ecosystems. Bioretention is a common GSI approach, used, for example in rain gardens, to infiltrate stormwater runoff into soils prior to or instead of discharging into a water body. Initial research has shown that bioretention is biologically effective for preventing most toxicity from urban runoff exposure, but initial trials used fresh bioretention soil media (BSM) with less than 5 repeated treatments. Does bioretention continue to be biologically effective at preventing toxicity over more treatment events? …
