Data for: Where is the nursery for amphidromous nekton? Abundance and size comparisons of juvenile ayu among habitats and contexts

These data provide difference of occurrence pattern of ayu among multiple habitats and contexts with physical parameters.
Each file name indicate data followings:
analysis_cpue: ayu cpue in each habitat and month for analysis by "R"
analysis_sal-ayuseason: variation of salinity in each habitat and month for analysis by "R"
analysis_temp-ayuseason: variation of water temperature in each habitat and month for analysis by "R"
analysis_cv-ayuseason: monthly coefficient of variance in salinity and water temperature
analysis_ayu-size: ayu standard-length in each habitat for analysis by "R"
Frequency_distribution_SL: frequency of standard length of ayu in each habitat and month
