Seasonal variations in the adult sex composition of P. inopinus from Mankyung River estuary (South Korea).
(A): Oligohaline, (B): mesohaline, (C): polyhaline. Circle : female; triangle: male.
Nota: Males were more abundant than females throughout the study period (January to December 2000) and across the entire range of salinity, but the ratio of males to females exceeded 50% under oligohaline conditions in January, mesohaline conditions in late fall and winter, and polyhaline conditions in early winter..
Gravid females appeared in oligohaline conditions in March, July, and September and accounted for 50% of all females present in September. Under mesohaline conditions, they occurred in June to October, and under polyhaline conditions, they occurred only in June and October, and >50% of all females were gravid in October.
These facts indicate that abundance of P. inopinus as P. poplesia may be controlled by Chl a concentrations and salinity conditions. |
