“…The Cu-tolerant and Cu-susceptible groups of offspring were the progeny of parents considered to be tolerant or susceptible based upon the reduction in their swim performance following an 8-9 days exposure to Cu. Details of the breeding program have been presented previously (Kolok et al, 2004). The Cu-tolerant progeny hatched from 8 to 16 July 2001, while the Cu-tolerant progeny hatched from 20 to 24 July.…”

“…For example, allozymic variation in polymorphic enzyme loci has been correlated with survival time in fathead minnows exposed to Cu for 96 h (Schlueter et al, 1995(Schlueter et al, , 1997. More recently, relative Cu tolerance of fathead minnows (as determined from reduction in swim performance following a sublethal exposure to Cu) has also been found to correlate with allozymic variation in polymorphic enzyme loci (Kolok et al, 2004).…”

The objective of this study was to determine if the relative Cu tolerance of fathead minnow parents determines the, relative Cu tolerance of their adult offspring. It was hypothesized that the adult offspring of Cu-tolerant minnows would inherit Cu tolerance from their parents. The relative Cu tolerance of 96 adult fish was determined based upon their reduction in swim performance following a sublethal exposure to 150 μg Cu/l. Control, Cu-tolerant and Cu-susceptible lines of fish were produced and fish within each line were allowed to breed. The offspring were raised to adults, then exposed to one of two sublethal Cu concentrations (150 or 225 (μg Cu/l) for 8 days. There were no significant differences in relative Cu tolerance, as measured by reduction in swim performance, among the three lines of fish at either dose. However, significant differences in whole body Na + occurred among the fish lines after exposure to 150 μg Cu/l, but not after exposure to 225 μg Cu/l. Significant differences in whole body Cu occurred between Cu-tolerant and Cu-susceptible fish lines after exposure to either Cu dose. The offspring did not inherit the relative Cu tolerance of their parents, however, the selection lines had diverged from each other, particularly with respect to their whole body Cu concentrations after exposure.

Integrating Bioavailability of Metals in Fish Population Models

Population models are increasingly being used to extrapolate individual-level effects of chemicals, including metals, to population-level effects. For metals, it is also important to take into account their bioavailability to correctly predict metal toxicity in natural waters. However, to our knowledge, no models exist that integrate metal bioavailability into population modeling. Therefore, our main aims were to 1) incorporate the bioavailability of copper (Cu) and zinc (Zn) into an individual-based model (IBM) of rainbow trout (Oncorhynchus mykiss), and 2) predict how survival-time concentration data translate to population-level effects. For each test water, reduced versions of the general unified threshold model of survival (GUTS-RED) were calibrated using the complete survival-time concentration data. The GUTS-RED individual tolerance (IT) showed the best fit in the different test waters. Little variation between the different test waters was found for 2 GUTS-RED-IT parameters. The GUTS-RED-IT parameter "median of distribution of thresholds" (m w ) showed a strong positive relation with the Ca 2+ , Mg 2+ , Na + , and H + ion activities. Therefore, m w formed the base of the calibrated GUTS bioavailability model (GUTS-BLM), which predicted 30-d x% lethal concentration (LCx) values within a 2-fold error. The GUTS-BLM was combined with an IBM, inSTREAM-Gen, into a GUTS-BLM-IBM. Assuming that juvenile survival was the only effect of Cu and Zn exposure, population-level effect concentrations were predicted to be 1.3 to 6.2 times higher than 30-d laboratory LCx values, with the larger differences being associated with higher interindividual variation of metal sensitivity. The proposed GUTS-BLM-IBM model can provide insight into metal bioavailability and effects at the population level and could be further improved by incorporating sublethal effects of Cu and Zn.
