Surprisingly the toxicity level of fertilizer industry discharge may influence by the environmental factors such as conductivity, temperature, pH, cardon dioxide (CO2), oxygen and elements. Through studies, these factors will influence the behavior and certain biochemical indices of the fish, such as C. striatus, by acting either in synergistic, antagonistic or simple additive manner (Yadav et al., 2005; Bobmanuel et al., 2006; Yadav et al., 2007). A high conductivity value indicates high concentration of dissolved ion within the industrial discharge. However, the conductivity value which recorded in this study was slightly below the required limit. Moreover, in this study the increased in fish mortality may due to. | The Performance of Florida s Spiny Lobster Trap Certificate Program by J. Walter Milon Sherry L. Larkin Donna J. Lee Kathryn J.
