Basic designs of digestive tracts. Notwithstanding the diversification of digestive systems caused by diversity among foods, Jumars and Penry () pointed out that most guts can be analyzed as one of three categories of ideal chemical reactors, or combinations of them: batch reactors (e.g., the gastric cavity of a hydra and the blindended cecum of a rabbit), plug-flow reactors (PFRs; e.g Juvenile yellow perch (Perca flavescens) were caught in a reference lake and transplanted to cages held within a lake impacted by mining activities, with elevated levels of aqueous bioavailable copper (Cu 2+), zinc (Zn 2+) and cadmium (Cd 2+). Fish were sampled from the cages over 70 d and changes in metal concentrations were followed over time in the gills, gut, liver and kidney. In

Introduction. Cadmium and copper are widespread pollutants of aquatic systems, largely as a result of mining and smelting activities. Both metals have been shown in laboratory studies to have significant deleterious effects on almost all physiological systems examined in fish, however mostly as a result of short-term aqueous exposure under standard laboratory conditions and using sensitive Effects of environmental metal contamination on the condition, swimming performance, and tissue metabolic capacities of wild yellow perch (Perca flavescens) Nevertheless, metal concentrations in yellow perch tissues have been correlated with biological impacts such as the metabolic imbalance of vitamin A 2 (Defo et al., ), impairment of metabolic In yellow perch, seasonal variations of tissue metal concentrations are well known (Couture et al., a;Levesque et al., ) and have been correlated to changes in condition (Audet and Couture Eighteen lakes studied near Sudbury and across Northeastern Ontario (Canada) over a five-year period provided a wide contamination gradient of cadmium (Cd), copper (Cu) and other metals such as nickel (Ni) and zinc (Zn).
All were inhabited by yellow perch (Perca flavescens), which This study determined the condition and reproductive output of a common estuarine toadfish, Tetractenos glaber, in two metal contaminated and two reference estuaries near Sydney, toadfish from metal contaminated estuaries were smaller and younger than in reference estuaries; however, it could not be resolved whether these differences were due to direct effects of metal metabolic capacities and protein concentrations were examined in yellow perch from two metal gradients (Sudbury, Ontario, and Rouyn-Noranda, Qu ´ ebec, Canada) in two seasons (spring and summer).
