In the study, the relationship between fish
size and otolith measurements in the Fries's goby (Lesueurigobius friesii)
were investigated. Fish specimens were collected by trawl operations from İzmir
Bay between September 2005 and August 2006. A total of 100 Lesueurigobius
friesii specimens were used for the study. Their total lengths
(TL) and weights were recorded by a fish ruler and a digital scale with an
accuracy of 0.1 cm and 0.01 g respectively. After that the fish were dissected
and their sagittal otoliths were removed. Otolith lengths and heights were
measured with an Olympus SZ61 stereo microscope with a micrometric ocular.
Otoliths were weighted by a digital scale with an accuracy of 0.0001 g. The
specimens used in the analysis were ranged between 5.5 and 8.7 cm total length
and from 14.8 to 56.4 g in total weight. The length–weight relationship
equations were estimated as W=0.0927*L2.9431 (r=0.942). Otolith
length (OL), otolith height (OH) and otolith weight (OW) of the species were
ranged between 2.6–4.1 mm, 2.2–3.4 mm and 0.0049–0.0204 g, respectively. The total
length–otolith length, total length–otolith height and otolith length–otolith
height measurements showed significant linear relationships. The relations
between the otolith weight–otolith length total length–otolith weight were
found to be exponential.
