Mr. Dewey et Sj. Zigler, AN EVALUATION OF FLUORESCENT ELASTOMER FOR MARKING BLUEGILLS IN EXPERIMENTAL STUDIES, The Progressive fish-culturist, 58(3), 1996, pp. 219-220
We evaluated subdermal injection of a fluorescent elastomer for markin
g bluegills Lepomis macrochirus in laboratory and pond studies. Markin
g did not affect the growth or survival of adult or juvenile bluegills
. Marks were visible for at least 6 months. This technique is a reliab
le, relatively inexpensive marking method for the identification of in
dividual fish in experimental studies. Costs of application range from
US$0.01 to $0.03 per mark.
