| description |
By means of an automatic recording device, the eífects of the exposure to sublethal
Solutions of Cd2+ (0.3 mg. L2) on some ethological parameters of
juvenile Cyprinus carpió (common carp) and Astyanaxfasciatus. The
effect of the metal was evaluated through three parameters: the total
swimming activity and the spatial (lateral and altitudinal)
preferences, relative to Controls (fish kept in tap water); they were
registered simultaneously by means oían original device. There were
determined successively the “normal” or standard levels of those
parameters in control fish and those reached by the same individuáis
aftertheir exposure to thereferencetoxic (Cd).
In both species the metal caused a depression of the total swimming
activity in a comparable magnitude. The altitudinal preference was
also modified: C. carpió was found more frequently in the superior
*e-mail: prodea@mail.unlu.edu.ar
layer of the aquaria while A. fasciatus was found in the inferior ones.
For the lateral preference, the individuáis of both species showed an
avoidance behavior of the site of the aquaria where the Cd Solutions
was dripping. This response of the animáis didn't follow a defined
pattem, but was more marked in the carps. All the evaluated responses
to the toxic were detected immediately after the beginning of the
exposure to Cd. The method proved to be sensitive and apt for the
monitoring of the measured behavioural parameters which makes it a
promising tool for biomonitoring purposes. We concluded that the
swimming activity and the spatial location preferences of the studied
species, among other, may be considered as biomarkers of aquatic
toxicity. |
