“…Continuing accumulation has been observed in rainbow trout exposed to 3.6 and 6.4 g liter −1 for 178 days (Giles, 1988). Plateaus in cadmium accumulation after 2-3 months have been reported in clams (Hemelraad et al, 1987) and in liver and kidney of zebrafish (Rehwoldt and Karimian-Teherani, 1976). Similar patterns of cadmium accumulation have been observed in this study.…”

“…No data are available, however, on the amount of ' "Cd washed out from the chorion during the time between spawning and collection of the eggs. Contrary to our results, Rehwoldt (1976) found no cadmium in the zebrafish offspring after oral administration of this metal. The observed levels of "' Cd in the embryos are low, however, and the spawning will probably play only a minor role in the elimination of cadmium.…”

The dynamics of a subtoxic pulse of non-dietary lo9Cd was followed for up to 304 days after the exposure period in female zebrafish. The retention of dietary IogCd was also estimated.The distribution of '09Cd was studied by autoradiography, whole-body analysis and tissue sampling. After exposure to non-dietary '09Cd for 10 days there was a rapid loss of '09Cd from the gills. The '"Cd content of the alimentary canal exceeded that which could have been expected from normal drinking. Based on the distribution pattern of non-dietary "' Cd in tissues, two groups of tissues were distinguished: (i) the gills, alimentary canal and heart which showed maximum lo9Cd values directly after exposure, followed by a pronounced decrease up to day 21; (ii) the liver, kidney, ovary and muscle, in which there was a delay in maximum lo9Cd activity to days 21-42. with subsequent loss.Small amounts of lo9Cd were noted in fry and fertilized eggs originating from zebrafish exposed to non-dietary '09Cd. After exposure to dietary '09Cd, less than 5% was retained in the zebrafish body, mainly in the alimentary canal.

“…In fact, the muscle cadmium level after a high concentration and longterm exposure is su⁄ciently high to cause concern (Kraal, Kraak, de Groot & Davids 1995). In contrast, a plateau in cadmium accumulation after 2 or 3 months has been reported in the liver and kidney of zebra¢sh (Rehwoldt & Karimian-Teherani 1976) and in carp exposed to 446 mg L À 1 Cd ( Succinate dehydrogenase is a marker enzyme of the Krebs cycle and has been used e¡ectively as a marker of mitochondrial abundance and activity to identify any possible physiological disturbance in ¢sh (Lehninger, Nelson & Cox 1993). Berntssen et al (2001) also observed a high Cd accumulation in muscle of Atlantic salmon fed with very high dietary Cd (125 and 250 mg kg À 1 ).…”

The present study was conducted to investigate the e¡ect of dietary cadmium (Cd) level on the growth, body composition and several enzymatic activities of juvenile yellow cat¢sh, Pelteobagrus fulvidraco. The experimental diets were formulated with CdCl 2 Á 2.5H 2 O at levels of 0, 0.01, 0.1 and 1.0 g kg À 1 diet, resulting in four dietary Cd levels of 0.25 (control), 4.92, 48.57 and 474.7 mg Cd kg À 1 diet respectively. They were fed to juvenile yellow cat¢sh (mean initial weight: 3.26 AE 0.07 g, mean AE SD) for 4 weeks. Weight gain, speci¢c growth rate, feed intake and protein e⁄ciency ratio tended to decline with increasing dietary Cd levels (Po0.05). In contrast, the feed conversion ratio was the lowest when the dietary Cd level was 0.25 mg Cd kg À 1 diet. Dietary Cd levels signi¢cantly in£uenced body composition and Cd accumulation. Whole body and vertebrae Cd content generally increased as the dietary Cd levels increased (Po0.05). However, muscle Cd content was detected only in ¢sh fed the diets containing the highest Cd level of the diet (P40.05). Hepatic alkaline phosphatase, glutathione peroxidase and lactate dehydrogenase activities increased (Po0.05) with increasing dietary Cd level. Succinate dehydrogenase was very variant and not related to dietary treatments. Malic dehydrogenase activity showed no signi¢cant di¡erences among the treatments (P40.05). The present study provided for the ¢rst time the toxic assessment of dietborne Cd in yellow cat¢sh, based on growth performance and the changes in hepatic enzymatic activities for the ¢sh species.
