Abstract
- The aims of the study were to determine total mercury concentrations in “rainbow trout Oncorhynchus mykiss (Walbaum)” at their embryo-larval and juvenile stages and to assess mercury concentration dynamics in individual tissues. Samples of rainbow trout were collected at two-month intervals over a period of 18 months (one stock production cycle) at...
Introduction
- Heavy metals are not as a rule primarily lethal for aquatic animals. However, their long-term negative effects cause developmental defects in fish, reproductive defects, and immunosuppression, and they may also cause ecological instability of aquatic ecosystems [1]. Growing heavy metal concentrations in the environment and subsequently in foods have becom…
Material and Methods
- Between 2008 and 2009, samples of rainbow trout (Oncorhynchus mykiss) ranging from hard row (A) to harvest-size fish (H) were collected at the Velká Losenice trout farm at regular intervals over the 18-month production cycle. Six groups had 10 fish each, while groups H and A consisted of 5 fish and 4 mixed embryo groups, respectively. Characteristics of individual groups, date of s…
Results
- Figure 4 showing weights of fish in the stock analyzed throughout the production cycle demonstrates the continuous growth of the fish, slightly slowed down in the winter period, and accelerated at the end of the cycle when feed intake levels and weight gains are the highest. Differences in the weight of fish from different age groups were statistically significant (𝑃<0.001)…
Discussion
- In a large majority of published studies on heavy metal concentrations in fish, concentrations of the metals were monitored only in individual fish or groups of fish captured for the purpose of monitoring environmental contamination or food quality [4, 7–12]. The present paper reports results of investigations into mercury concentrations of rainbow trout reared for commercial pur…
