Abstract

The principle objectives of this research analysis were to determine the uptake and turnover rates of carbon and nitrogen stable isotopes in fish and to establish if this isotope verification procedure is possible by testing tissue samples of their fins. This investigation is separated into two main experiments: first, the stable isotope incorporation in the new growth of fin tissue, and second, the rate of stable isotope turnover in the old growth of fin tissue. Both experiments of this study were done with Gambusia affinis, a species of fish better know as mosquito fish.
