Abundance of each fish species encountered in Otomi, Sezaki, and Nagahama in each census.

Southern and northern limit of distribution (SLD and NLD, based on Nakabo [19]) and their mean [= COD (center of distribution in the northern hemisphere)] are shown for each species. Each species was categorized into Temp (= temperate), Subtrop (= subtropical), or Trop (= tropical) according to the FishBase [24]. The codes each represent a census site and year; e.g., O04 represents Otomi in the year 2004. Bottom water temperature (Temp.) was recorded during each census. (XLS)
