- Abstract
- Striped seabream Lithognathus mormyrus [n = 1269; total
lengths (TLs) = 112-350 mm] were investigated in two coastal
Sicilian fishing grounds (central Mediterranean Sea). Samples
were collected from the two landing harbours, Licata and
Selinunte, between October 1999 and September 2000. Seasonal
and spatial variations in population structure, age,
growth, reproduction and mortality were studied. It was found
that seasonal differences in the main modes of length-
frequency distributions corresponded well with the seasonal
growth. The recruits in Licata grew faster and attained a larger
size (by 10-20 mm) at ages up to 2 years than in Selinunte.
Growth thereafter was relatively slow, with Selinunte specimens
growing at a slightly faster rate. Spawning occurred
between June and August. Length at the first maturity was
different between females and males in the Selinunte (190-
181 mm) and Licata (183-171 mm) fishing grounds. The
species displayed protandrous hermaphroditism, and somatic
growth practically ceased during the period of sex inversion.
Total fishing mortality was considerably higher in Licata
(F between 0.53 and 0.63 per year) than in Selinunte
(F between 0.22 and 0.29 per year). Therefore it is suggested
that the striped seabream population in Licata is more
vulnerable to overfishing than that in Selinunte. (literal)
