Title: Relationships between water and paddlefish Polyodon spathula dentary elemental and stable-isotopic signatures: potential application for reconstructing environmental history

Abstract

The objectives of this study were to characterize relationships between water and paddlefish Polyodon spathula dentary Sr:Ca, δ 18O and stable hydrogen isotope ratio (δD) to determine the accuracy with which individual P. spathula could be assigned to their collection locations using dentary-edge Sr:Ca, δD and δ 18O. A laboratory experiment was also conducted to determine whether dentary Sr:Ca in age 0 year P. spathula would reflect shifts in water Sr:Ca to which fish were exposed. Significant linear relationships between water and dentary Sr:Ca, δD and δ 18O were observed, although the relationship between water and dentary δ 18O was weaker than those for Sr:Ca and δD. Classification success for individual fish to collection locations that differed in water Sr:Ca, δD and δ 18O ranged from 86 to 100% based on dentary-edge Sr:Ca, δD and δ18O. Dentary Sr:Ca increased significantly in laboratory-reared age 0 year P. spathula following 4 weeks of exposure to elevated water Sr:Ca; dentary Sr:Ca of fish held in water with elevated Sr:Ca was also significantly higher than that of control fish reared in ambient laboratory water. Results indicated that P. spathula dentaries reflect water signatures for commonly-applied natural chemical markers and strongly suggest that dentary microchemistrymore » and stable-isotopic compositions will be applicable for reconstructing P. spathula environmental history in locations where sufficient spatial differences in water chemistry occur.« less

  • The paddlefish, Polyodon spathula, is a primitive fish characterized by a predominantly cartilaginous skeleton, a virtually scaleless body, and a rostrum or paddle nearly one-third of the body length. At the Falls of the Ohio River near Louisville, KY, paddlefish are harvested for their roe used to produce domestic caviar. The persistence of this small but intensive fishery for the roe of female paddlefish may be slowing or even reversing the recovery of populations in the Falls area of the Ohio River. Residues of toxic substances harmful to humans are being detected in many fishes in the Ohio River. Organochlorinemore » pollutants such as chlordane and polychlorinated biphenyls (PCBs) are being detected at levels as high as those of 10 yr ago. Recent data from studies conducted in the Missouri River on PCB levels in the tissues of the shovelnose sturgeon, a species closely related to the paddlefish, indicate that the concentration of PCBs in sturgeon roe is several times that of concentrations in flesh. This study examines the PCB content of the roe of paddlefish at the location of a commercial fishery. The study investigated the partitioning of PCBs into the muscle and reproductive tissues of paddlefish, considered possible correlations between PCB concentration and age and percent lipid, and looked at the existence of any differences in mean PCB concentrations between male and female paddlefish. 17 refs., 1 fig., 1 tab.« less
  • During the period August 1974-July 1975, an estimated 4382 paddlefish were impinged on the intake screens at the Gallatin Steam Plant. An additional 9258 paddlefish were estimated to have been impinged from August 1975-May 1976. Practically all paddlefish impinged were age group 0 (young-of-year). Because the number estimated to have been impinged was higher at Gallatin Steam Plant than at any other TVA installation, and because paddlefish are infrequently collected in most fisheries investigations, TVA initiated a study to provide the data necessary for a better assessment of the effects of impingement mortality on the paddlefish population in Old Hickorymore » Reservoir. This report presents results of these investigations and, because of the paucity of scientific literature, also serves as a state-of-the-art report on many facets of paddlefish biology. Specifically the study was designed to determine age structure, growth, movement, reproductive biology, year-class strengths, and abundance of paddlefish in Old Hickory Reservoir.« less
  • In January, 1986, approximately 10,700 yearling paddlefish were released in Cherokee Reservoir. Initial mortality was apparently low, with fewer than 100 stocked paddlefish found dead in the vicinity of the release site. Subsequent sampling has yielded little data on distribution and abundance of paddlefish in Cherokee Reservoir. Observations suggest young paddlefish dispersed widely and may not have experienced heavy mortality. (ACR)
  • TVA has investigated young-of-year (YOY) paddlefish impingement at the Gallatin Steam-Electric Plant (GAF) for several years. The objective of the investigations has been to relate YOY paddlefish abundance and distribution in Old Hickory Reservoir to impingement mortality at GAF. Impingement at GAF was monitored and, if paddlefish impingement was significant, distribution, abundance, and health of YOY paddlefish in Old Hickory Reservoir was to be intensively studied. This approach was continued through 1986.

Effects of elemental composition on the incorporation of dietary nitrogen and carbon isotopic signatures in an omnivorous songbird. Oecologia. 135:516-523. The use of stable isotopes to infer diet requires quantifying the relationship between diet and tissues and, in particular, knowing of how quickly isotopes turnover in different tissues and how isotopic concentrations of different food components change (discriminate) when incorporated into consumer tissues. We used feeding trials with wild-caught yellow-rumped warblers (Dendroica coronata) to determine d15N and d13C turnover rates for blood, d15N and d13C diet-tissue discrimination factors, andmore » diet-tissue relationships for blood and feathers. After 3 weeks on a common diet, 36 warblers were assigned to one of four diets differing in the relative proportion of fruit and insects. Plasma half-life estimates ranged from 0.4 to 0.7 days for d13C and from 0.5 to 1.7 days for d15N. Half-life did not differ among diets. Whole blood half-life for d13C ranged from 3.9 to 6.1 days. Yellow-rumped warbler tissues were enriched relative to diet by 1.7.3.6% for nitrogen isotopes and by 1.2 to 4.3% for carbon isotopes, depending on tissue and diet. Consistent with previous studies, feathers were the most enriched and whole blood and plasma were the least enriched or, in the case of carbon, slightly depleted relative to diet. In general, tissues were more enriched relative to diet for birds with high percentages of insects. For all tissues, carbon and nitrogen isotope discrimination factors increased with carbon and nitrogen concentrations of diets. The isotopic signature of plasma increased linearly with the sum of the isotopic signature of the diet and the discrimination factor. Because the isotopic signature of tissues depends on both elemental concentration and isotopic signature of the diet, attempts to reconstruct diet from stable isotope signatures require mixing models that incorporate elemental concentration.« less
