Evidence of rainbow smelt (Osmerus mordax) spawning in Mohican Canyon, a tributary of Otsego Lake
Groups of Rainbow smelt were observed spawning in the first riffle in Mohican Canyon upstream of Otsego Lake. Adult smelt were collected with a shore seine on 22 April 2001. Sampled fish (n=17) had an average length of 176.8 mm total length (TL) and weight of 34.2 g. Despite these observations, no larval, juvenile or adult smelt were collected in any trawling or gill netting activities in Otseg...
متن کاملOsmotic pressure-adaptive responses in the eye tissues of rainbow smelt (Osmerus mordax)
PURPOSE The rainbow smelt (Osmerus mordax), is a teleost fish, which avoids freezing by becoming virtually isosmotic with seawater. The effects that such massive changes in osmolarity have on both its visual system and its highly evolved and specialized circulation are not known. New knowledge about the osmotic adaptation of the rainbow smelt eye is highly relevant to the adaptation and surviva...
متن کاملRelationship between food availability, glycerol and glycogen levels in low-temperature challenged rainbow smelt Osmerus mordax.
Rainbow smelt Osmerus modax accumulate glycerol in winter that serves as an antifreeze. Fish were held at 8 degrees C, or subjected to a decrease in water temperature to -1 degrees C over a 19 day period, and subsequently maintained at -1 degrees C from 15 January to 11 May 2004. Starved fish did not survive the challenge of temperature decrease, with death ensuing above the typical freeze poin...
متن کاملMolecular analysis, tissue profiles, and seasonal patterns of cytosolic and mitochondrial GPDH in freeze-resistant rainbow smelt (Osmerus mordax).
Rainbow smelt (Osmerus mordax) is an anadromous teleost that, beginning in late fall, accumulates plasma glycerol in excess of 200 mM, which subsequently decreases in the spring. The activity of cytosolic glycerol-3-phosphate dehydrogenase (cGPDH) is higher (i) in liver of smelt than in that of Atlantic salmon and capelin (nonglycerol accumulators), (ii) in liver of smelt maintained at 1°C than...
متن کاملMitochondrial DNA diversity in anadromous rainbow smelt, Osmerus mordax Mitchill: a genetic assessment of the member–vagrant hypothesis
We analyzed mitochondrial DNA genetic variance in anadromous smelt to test whether the ecological processes inferred by the member–vagrant hypothesis to explain spatial patterns of abundance may also have evolutionary consequences for the process of population divergence. Restriction enzyme analysis was performed on 568 adult smelt from 16 sites within the estuary and the Gulf of St. Lawrence (...
