Title Some observations on the size distribution and the
Occurrence of growth rings in the scales of three
Species of cynoglossus at Calicut
 
Creator Seshappa, G
 
Subject Fishery biology
 
Description Observations have been made on the length-frequency trends in three of
the less common species of Cynoglossus at Calicut during the years 1969-73, these
species being C. bilineatus (Lacepede). C. puncticeps (Richardson) and C. lida
(Bleeker). As these species occur only as occasional specimens in the fish catches,
large samples were not available for studying the month-to-month variation patterns
in the size distribution, and so the annual totals are considered here, and these
give some idea of the sizelimits and the prevailing sizes during the different years.
204 individuals of C. bilineatus were measured during the psriod (5-5.9 to BBSS.
9 cm); of C. puncticeps, 316 specimens were measured (5-5.9 to 20-20.9 cm
groups); and of C. lida, 138 individuals were measured (14-14.9 cm to 21-21.9 cm).
In all the three species, the scales revealed growth rings comparable to those
described in the case of the Malabar sole, C. macrostomus (Norman); the trend of
occurrence of these growth rings in the three species is described and discussed.
