ABSTRACT

The effect of static magnetic field on the choice of direction of movement
of sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata)
fry in a research setting, in which the fish had the option of swimming to one
of four chambers at whose entrance magnetic field higher than the Earth's magnetic
field was generated. Results on research on sea bream fry show significant correlations
between the choice of direction of movement and the level of generated magnetic
field. No such response was noted in the case of sea bass fry. These results
suggest that some species of fish, despite inhabiting a very characteristic,
environment of which the Adriatic coast is, where there is stratification of
salinity and temperature and within which migrations of sea bream and sea bass
to reproduction and feeding grounds take place, show changes in the direction
of movement under the influence of artificially generated magnetic field, and
most probably are guided by changes in magnetic field gradient during migrations.

Key words: Adriatic Sea, directional responses, fish fry, magnetic field, sea bream, sea bass .
