    Influence of waterborne cations on zinc uptake and toxicity in rainbow trout, Oncorhynchus mykiss Derek H. Alsop and Chris M. Wood Abstract: The effects of waterborne cations on 65Zn uptake, Zn toxicity, and relationships with Ca uptake were examined in juvenile rainbow trout, Oncorhynchus mykiss, in soft water. Brook trout gill, liver, kidney, and opercular bone tissues accumulated the greatest amounts of zinc. Edible muscle tissue did not accumulate zinc. Zinc loss from gill and liver from first‐generation trout transferred to control water for 12 weeks was 55% and 59%, respectively, based on the total micrograms of zinc per whole tissue.

Lloyd () found that rainbow trout reared in hard water and acclimated to softer water for no longer than 3 days had similar zinc toxicity results when tested in both hard and soft water. Further experi­ ments revealed that rainbow trout reared in hard water had to be acclimated to soft water for a minimum of 5 days.

In order to estimate acute-to-chronic toxicity ratios (ACRs) relevant to a coldwater stream community, we exposed rainbow trout (Oncorhynchus mykiss) to cadmium (Cd), lead (Pb), and zinc (Zn) in h acute and 60+ day early-life stage (ELS) exposures. We also tested the acute and sublethal responses of a mayfly (Baetis tricaudatus) and a midge (Chironomus dilutus, formerly C. tentans) with Pb.

This study included three separate exposures of rainbow trout (Salmo gairdneri) and brook trout.(Salveli.""5 fontinalis) to zinc (as the sulfate) in hard and soft water to determine acute lethality, to compare toxicity differ- ences between the two species, and to determine the effects of water quality changes on the toxicity of zinc to each.

EPA/ Google Scholar Litchfield JT, Wilcoxon F () A simplified method of evaluating dose-effect by: 3. The intrinsic toxicity of zinc within fish may be defined as the amount of zinc present in the gills (the site of acute toxicity) at death. This intrinsic toxicity was similar in rainbow trout (Salmo gairdneri Richardson) that were exposed to zinc in acid or neutral water (pH or ) and in hard or soft water (total hardness or 30 mg CaCO 3 /L).

In this study, the effects of modifying Ca (−4 mM), Mg (−3 mM), Na (−5 mM), and pH (−) on the chronic toxicity of zinc to juvenile rainbow trout (Oncorhynchus mykiss) were investigated using standard d assays in which survival and growth were monitored.

Survival was observed to be a more sensitive end point than growth, and mortality mainly occurred during the. Jam-packed full of things to spot, questions to answer and details to discover, all from Elmer's colourful world.

In this study, the effects of modifying Ca ( mM), Mg ( mM), Na ( mM), and pH () on the chronic toxicity of zinc to juvenile rainbow trout (Oncorhynchus mykiss) were investigated using standard d assays in which survival and growth were monitored.

A short-term method was developed in this study for conducting subchronic survival and growth renewal toxicity tests with rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis). Previously published early life-stage methods for various salmonid species involve test durations of 30 to 90 days.

This trout method, however, follows a previously published 7-day fathead minnow. The Acute Toxicity to Rainbow Trout of Fluctuating Concentrations and Mixtures of Ammonia, Phenol and Zinc † V.

The Acute Toxicity of Phenol to Rainbow Trout in Saline Waters DISCUSSION The pattern of response to phenol contrasts markedly with that for zinc and ammonia (HERBERT and WAKEFORD, ; HERBERT and SHURBEN, ) and ideal- ized curves for the three poisons are shown together in FIG.

These studies permitted evaluation of key components of intermittent exposures (toxicant concentration. 1. Introduction. Previous studies have shown that high water hardness reduced the acute toxicity of zinc to fish and lowered the accumulation of zinc in both gills and whole body of fish (Mount,Solbe,Zitco and Carson,Everall et al., ).For example, zinc was 27 times more toxic to rainbow trout (Oncorhynchus mykiss) in hard water ( mg CaCO 3 /l) than in soft water.

Anchovy oil is a very suitable supplementary ingredient for fish feeds due to the essential fatty acid composition. The acute toxicity of zinc and copper ions for rainbow trout (Oncorhynchus mykiss Walbaum ) were evaluated by static bioassays. The average weight and length of fish used in the zinc experiments were 3,02± g and ± cm, respectively, while the tests with copper.

Continuous-flow acute toxicity tests were conducted in soft water to determine the effect of pH on the toxicity of cadmium, copper, and zinc to small (1–6 g) steelhead trout (Salmo gairdneri).
