“…Cad mium toxicity was about seven-fold lower in the hardwater acclimated fish (8.0 mM Ca2 + ) than in fish from water containing 0.5 mM Ca2 + . Increased mortality was observed in the larvae and juveniles of striped bass exposed to cadmium in soft water, whereas in hardwater cadmium toxicity and uptake was reduced (Palawski et al 1985;Wright et al 1985). Similar effects of water hardness on rainbow trout exposed to copper (Lauren and McDonald 1986) and zinc (Bradley and Sprague 1985) have been reported.…”

“…In contrast to calcium, magnesium, sodium or potassium entering the body via both the gills and gut of tilapia, phosphate is absorbed exclu sively via the gut (Flik et al 1985b). In mammals, calcium and phosphate homeostasis of the extracel lular fluid is highly dependent on the skeletal tissue for the exchange of calcium and phosphate (Martin et al 1985). It has long been questionable whether minerals can be mobilized from the acellular type of bone that occurs in most teleost fish, including ti lapia (Weiss and Watabe 1979).…”

The effects of cadmium administered via ambient water or food on plasma ions of the Af rican freshwater cichlid Oreochromis mossambicus were studied for 2, 4, 14, and 35 days, in low cal cium (0.2 mM) and high calcium (0.8 mM) water. In low calcium water, an environmentally relevant concentration of 10 fig/L water-borne cadmium in duced a significant and dramatic hypocalcemia on days 2 and 4. Recovery of plasma calcium was ob served on days 14 and 35. Hypermagnesemia was observed on day 2, but normal levels were already found on day 4. In high calcium water adapted fish, the extent of hypocalcemia and hypermagnesemia was less pronounced than in fish from low calcium water. Water-borne cadmium caused no significant changes in plasma phosphate, sodium, potassium, or osmolality. On days 2 and 4, dietary cadmium (averaging 10 fxg Cd/fish/day) caused hypermagne semia and hypocalcemia in low calcium wateradapted fish. Recovery was observed on days 4 and 14, respectively. In fish from high calcium water, dietary cadmium caused a significant reduction in plasma calcium on day 4 only; plasma magnesium was unaffected. Hyperphosphatemia was apparent on day 14, irrespective of the water calcium con centration. No changes in plasma sodium, potas sium, or osmolality were found.^V r c h i v e a oThe results show that sublethal concentrations of cadmium, administered via the water as well as via the food, affect calcium and magnesium metabo lism in tilapia.

“…In the present study, embryos exposed to Ni and NH 3 ‐N did not have significantly different heart rates from controls. Cadmium toxicity was also a strong indicator of cardiotoxicity and has been shown to affect Ca metabolism (Wright et al, 1985) of juvenile striped bass ( Morone saxatilis ), which is vital in its role of cardiovascular health and physiological components. Moreover, Cd 2+ was shown to induce inhibition of the L‐type calcium current for ventricular myocytes (Haverinen et al, 2021) in rainbow trout.…”

The fathead minnow (Pimephales promelas) fish embryo acute toxicity (FET) test was compared to the fish gill cells (RTgill‐W1) in vitro assay and to the fish larvae acute toxicity test to evaluate their sensitivity for whole‐effluent toxicity (WET) testing. The toxicity of 12 chemicals relevant for WET testing was compared as proof of principle. The concentrations lethal to 50% of a population (LC50) of embryos were compared to those in fish larvae and to the 50% effect concentration (EC50) in RTgill‐W1 cells from previous literature. Along with traditional FET endpoints (coagulation, somite development, tail detachment, and heartbeat), cardiotoxicity was evaluated for WET applicability. Heart rate was measured at LC20 and LC50 values of six subselected chemicals (Cd, Cu, Ni, ammonia, 3,4‐dichloraniline, and benzalkonium chloride). In addition, the toxicity of Cd and Ni was evaluated in RTgill‐W1 cells exposed in a hypoosmotic medium to evaluate the effect that osmolarity may have on metal toxicity. A significant correlation was found between the FET and larvae LC50 values but not between the RTgill‐W1 EC50 and FET LC50 values. Although sensitivity to Ni and Cd was found to increase with hypoosmotic conditions for FET and RTgill‐W1 cells, a correlation was only found with removal of Ni from the analysis. Hypoosmotic conditions increased sensitivity with a significant correlation between RTgill‐W1 cells and larvae. Cardiotoxicity was shown in three of the five subselected chemicals (Cd, Cu, and 3,4‐dichloroaniline). Overall, both in vitro alternative models have shown good predictability of toxicity in fish in vivo for WET chemicals of interest. Environ Toxicol Chem 2022;41:2721–2731. © 2022 SETAC

“…At 7-d-old, mummichogs (Fundulus heteroclitus) are more sensitive to Cd than at 1-or 14-d-old (Middaugh and Dean, 1977). Similarly, Wright et al (1985) reported that 7-d-old striped bass (Morone saxatilis) had increased Cd sensitivity relative to 6-week-old bass. Hwang et al (1995) found that 3-d-old tilapia larvae were more sensitive to Cd than 0-, 1-, 2-or 7-d-old larvae.…”

This study had two primary objectives. The first was to determine if the length of exposure necessary for acclimation to Cu to develop in larval fathead minnows (Pimephales promelas) is different than that for juveniles. The second objective was to determine whether the acclimatory response, as determined by organism survival, is consistent with acclimation as determined by whole-body Na + . Six experiments were conducted: four using larval (<20-d-old) and two using juvenile (<60-dold) fathead minnows. Within each experiment, fish were allocated to one of four groups: unexposed, continuously exposed, episodically exposed or naïvely exposed. The continuous group was exposed to a sublethal Cu exposure (125 µg/L) for 8, 12, 16 or 20 d and then subjected to a survival test at a lethal dose (375 µg/L). Fish in the episodic group were exposed to the sublethal dose for either 4 or 8 d, given a depuration period of varying lengths (4-16 d) then subjected to a survival test. Naïve minnows were maintained in clean water then given the survival challenge. Results from survival tests show that the larvae acclimate after only a 4-d sublethal exposure to Cu. In contrast, juveniles require a 16-d exposure to acclimate. Once acclimation had developed, there was a strong relationship between larval survival and whole-body Na + . Acclimated larvae maintained whole-body Na + relative to unexposed fish, while unacclimated larvae did not. Interestingly, this was not the case for juveniles, as acclimated and unacclimated groups did not differ with respect to whole-body Na + concentrations. The results of this study show that age influences the time course and possibly the mechanisms of acclimation in fathead minnows exposed to Cu.
