淡水紅樹林沼澤區螃蟹種類分佈之調查

The Crab Fauna of Tan-Shui Mangrove Swamp

摘要


本調查工作,於1982年6月至1983年5月,在淡水紅樹林沼澤區面積約五十四公頃之範圍內進行。調查結果顯示,該區螃蟹計有十屬十五種,分屬在蟳科(Portunidae)、招潮科(Ocypodidae)、四角蟹科(Grapsidae)及Mictvridae等四科,其中招潮蟹科內之臺灣招潮(Ucaiormosensis)為臺灣特有種,數量稀少而珍貴。螃蟹族羣之分佈,一般而言,招潮科者較喜分佈在較空曠之砂質土上(Sandy loam),排水性佳,含水量低,有機質含量少。四角蟹科者則較喜分佈在有植被之砂直壤土上(Silt loam),含水量及有機質含量皆高。

This investigation was done in Tan-shui mangrove swamp from June 1982 to May 1983. Results indicate that there were four families of crabs: Protunidae, Ocypodidae, Grapsidae and Mictyridae, including 10 genera and 15 species in the studied area. Among these crabs, Uca, formosensis is an endemic and a rare species. As to the habitat selection, Ocypodidae prefers in less vegetated area with the sandy loam. Grapsidae is found only in densly vegetated section with the silt loam. The single species of Portunidae distributes only in the rather muddy area. Mictyridae stays only in the sandy beach, near Tan-shui river.
