Fish require copper (Cu) and zinc (Zn) as micronutrients (Watanabe et al., ) and can obtain these metals from either water or their diet (Handy,Wood, ).The mechanisms of waterborne Cu and Zn uptake and toxicity to fish gills are beginning to be well understood (), however, the uptake and toxicity of dietborne metals in fish is not as well :// The toxicity of two different biochars (pine chip and poultry litter char) on Eisenia fetida applied to an artificial soil (70% sand, 20% kaolin, and 10% sphagnum) was investigated at five   Studies on the nutrition of marine flatfish.

3 Dietary toxicity of metals to other aquatic animals There have been fewer studies of the dietary toxicity of metals using other aquatic animals. Focusing on amphipods, Besser et al. [52] studied the acute and chronic toxicity of Acute toxicity tests with juvenile mussels. Eight acute h NaCl tests were conducted concurrently in September with newly transformed fatmucket (~10 d old).

Four of the 8 NaCl tests were conducted in, and hard waters to evaluate influence of hardness on NaCl toxicity to juvenile In the “Blue Book” and the “Red Book” that followed (US Environmental Protection Agency), the WQC recommendations were not single values but instead expressed acceptable exposures relative to the acute toxicity of the metal to “the most sensitive important species in the locality” when tested in the actual receiving water   Macrobrachium rosenbergii is well-known as the giant freshwater prawn, and is a commercially significant source of seafood.

Nevertheless, a number of studies have indicated that zinc toxicity is species-specific and varies with developmental stages (Ho et al., ).

The most sensitive indicator of toxicity was sexual maturity, after 70 d at mg/L zinc, significantly fewer females had matured. At mg/L zinc, fewer females (50%) gave birth and the.
