Sažetak
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.
