Abstract

Objective: The
present study reports morphometric characteristics for Pagellus acarne caught
by trawl from the Antalya Gulf
(Mediterranean-Turkey). In addition, length-weight
relationships are also estimated and compared with those estimated from other
areas.

Methods: Individuals of P.
acarne were collected during September - December 2011
from trawl surveys conducted in the Antalya Gulf (Mediterranean-Turkey).
Morphometric characters were measured directly on the fish body (15
characteristics) and head (7 characteristics). Meristic characters were
counted.
Length-weight relationship was calculated using the
equation W = aTL^b.

Results: During the study
period, a total of 360 specimens of P. acarne, ranging
in size from 8.9 to 26.7 cm in total length and from 7.7 to 275 g in total
weight, were collected. The length-weight relationship for all individuals was
described by the parameters a = 0.0057 and b = 3.29. From the twenty one morphometric
characters the13 were showed allometric growth according to TL while the 8
morphometric characters were showed isometric growth according to TL. The
proportions of the examined morphometric characters were ranged from 0.02 (for
the lenght of the base of ventral fin) to 0.51 (for the preanal distance).

Conclusion: The morphometric characters were showed strong correlation with the TL. Length - weight relationship showed that the P. acarne  populations grow allometric (Weight increased
allometrically with length).
