ASIMETRIJA ŠIRINE I DUŽINE OTOLITA ODRASLIH TELEOSTIDA (Beryx splendens LOWE, 1834) (PORODICA:BERCIDAE) ULOVLJENIH UZ OBALU ARAPSKOG MORA U OMANU

Fluctuating asymmetry was described for the otolith width and length of adult teleost Beryx splendens. The results showed that the level of asymmetry of the otolith width was the highest among the two asymmetry values obtained for the otolith of B. splendens. For the otolith width character, the results showed that the level of asymmetry at its highest value in fish ranging in length between 191–200 mm and in its lowest value in fish ranging in length between 121–180 mm. For the otolith length, the highest value of asymmetry is noticed in fish ranging in length between 231–244 mm and the lowest value in fish within the length of 121–190 mm. The possible cause of the asymmetry in this species has been discussed in relation to different pollutants and their presence in the area. No trend of increase in the asymmetry values with the fish length was noticed for the otolith width, but there is a weak trend of increase with the fish length in case of otolith length character.U radu je prikazana promjena asimetrije širine i dužine otolita odraslih primjeraka Beryx splendens. Dobiveni rezultati pokazuju da su vrijednosti asimetrije širine bile više u riba koje su bile duge između 191 i 200 mm, a kod riba dužine između 121 i 180 mm vrijednosti su bile niže. Vrijednosti dužina otolita bile su više u riba dugih između 231 i 244 mm, a u riba dužine između 121 i 190 mm vrijednosti bile su niže. Mogući uzrok spomenute asimetrije razmatran je u odnosu na različite onečišćivače i njihovu prisutnost u tom području. Nije primijećeno povećanje vrijednosti asimerije širine otolita s obzirom na dužinu riba, ali je zapaženo slabo povećanje vrijednosti dužine otolita u odnosu na veličinu riba
