2005 journal article

Implications of Pylodictis olivaris (flathead catfish) introduction into the Delaware and Susquehanna drainages

NORTHEASTERN NATURALIST, 12(4), 473–484.

By: J. Brown, J. Perillo, T. Kwak*  & R. Horwitz

TL;DR: The introduction of flathead catfish into the Delaware and Susquehanna River drainages represents the northernmost occurrences among Atlantic drainages and has the potential to adversely affect ongoing anadromous fish restoration programs and native fish conservation efforts.

2005 journal article

Assessing organic contaminants in fish: Comparison of a nonlethal tissue sampling technique to mobile and stationary passive sampling devices

ENVIRONMENTAL SCIENCE & TECHNOLOGY, 39(19), 7601–7608.

By: R. Heltsley*, W. Cope* , D. Shea* , R. Bringolf*, T. Kwak*  & E. Malindzak*

MeSH headings : Adipose Tissue / chemistry; Animals; Body Burden; Catfishes / metabolism; Environmental Monitoring / instrumentation; Environmental Monitoring / methods; Environmental Monitoring / statistics & numerical data; Muscle, Skeletal / chemistry; North Carolina; Pesticides / analysis; Polychlorinated Biphenyls / analysis; Water Pollutants, Chemical / analysis
TL;DR: Investigation of two novel methods for estimating organic contaminants in fish demonstrated for the first time that organic contaminant concentrations in adipose fin were highly correlated with muscle fillet concentrations, indicating that the adipose fins of certain fishes may be used to accurately estimate tissue concentrations without the need for lethal sampling.

Reference ranges for hemolymph chemistries from Elliptio complanata of North Carolina

DISEASES OF AQUATIC ORGANISMS, 65(2), 167–176.

By: L. Gustafson*, M. Stoskopf*, W. Showers*, G. Cope, C. Eads*, R. Linnehan, T. Kwak* , B. Andersen*, J. Levine* 

author keywords: Elliptio complanata; hemolymph; hematology; reference ranges
MeSH headings : Animals; Bivalvia / chemistry; Bivalvia / parasitology; Blood Chemical Analysis; Body Weights and Measures; Fresh Water; Geography; Hemolymph / chemistry; Likelihood Functions; North Carolina; Reference Values; Statistics, Nonparametric
TL;DR: A set of reference ranges for clinical evaluation of hemolymph from a freshwater mussel species common to southeastern USA is developed to aid the interpretation of health measures from populations of E. complanata of similar geographic and seasonal origin. (via Semantic Scholar)

Evaluation of a nonlethal technique for hemolymph collection in Elliptio complanata, a freshwater bivalve (Mollusca : Unionidae)

DISEASES OF AQUATIC ORGANISMS, 65(2), 159–165.

By: L. Gustafson  n, M. Stoskopf*, A. Bogan*, W. Showers*, T. Kwak* , S. Hanlon, J. Levine n 

author keywords: unionidae; freshwater mussels; hemolymph; nonlethal sampling
MeSH headings : Animals; Bivalvia; Blood Specimen Collection / methods; Evaluation Studies as Topic; Fresh Water; Hemolymph / chemistry; North Carolina; Survival Analysis
TL;DR: It is concluded that collection of hemolymph from the adductor sinus is safe for sampled E. complanata and should be explored as a relatively non-invasive, and potentially useful, approach to the evaluation of freshwater mussel health. (via Semantic Scholar)

2005 journal article

Assessing ecological integrity of Ozark rivers to determine suitability for protective status

ENVIRONMENTAL MANAGEMENT, 35(6), 799–810.

By: A. Radwell* & T. Kwak n 

author keywords: antidegradation; biotic integrity; ecological integrity; reference conditions; river bioassessment; Ozarks; wild and scenic rivers
MeSH headings : Animals; Conservation of Natural Resources / economics; Ecology; Environmental Monitoring; Fishes; Food Chain; Invertebrates; Ownership; Plants; Population Dynamics; Rivers
TL;DR: Two objective, quantitative methods to determine stream ecological integrity of headwater reaches of 10 Ozark rivers, 5 with Wild and Scenic River federal protective status, provide a framework for refinement and application in other regions to facilitate the process of establishing least-disturbed reference conditions and identifying rivers for protection and restoration.

Salinity tolerance of flathead catfish: Implications for dispersal of introduced populations

TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY, 134(4), 927–936.

By: R. Bringolf n, T. Kwak n , W. Cope n  & M. Larimore*

TL;DR: Evidence is provided that flat head catfish could tolerate exposure to many brackish waters along the Atlantic and Gulf of Mexico coasts of the United States and that the dispersal of introduced flathead catfish populations among rivers may not be limited by estuarine salinities.

Diet selectivity of introduced flathead catfish in coastal rivers

TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY, 134(4), 901–909.

By: W. Pine n, T. Kwak n , D. Waters n & J. Rice n

TL;DR: The food habits of introduced flathead catfish Pylodictis olivaris are found to be primarily piscivorous, which could restructure or suppress native fish communities through direct predation, and Chesson's selectivity index values and trends in relative abundances of fish availability relative to those occurring in the diet suggest that flat head catfish feeding is generally random.
