Abstract: | Coloration and sex change were studied in a temperate wrasseHalichoeres poecilopterus in the central part of the Seto Inland Sea, Japan. 1,270 examples, 45–179 mm SL, were collected from May to December both
in 1983 and 1984. The species is a diandric, protogynous hermaphrodite, and has three color patterns: pale color type (A),
brilliant color type (B) and intermediate color type (AB). A-fish were less than 142 mm SL and consisted of primary males
(42.6%), females (55.4%), secondary males (0.3%) and fish with transitional gonads (1.7%). A-females changed their color to
B, through AB, in the size range 101–131 mm SL. A-primary males changed their color to B, through AB, in the size range 103–134
mm SL. B-fish consisted of primary males (38.6%), secondary males (54.6%) and fish with transitional gonads (6.8%). The majority
of females changed their sex to male in the size range 98–131 mm SL. |
