This is largely due to the fact that species-level diagnostic features in this group are mainly morphometric(highly variable and easily distorted in the process of specimen preservation), too often decisions based on such traits are either imprecise or arbitrary, thus it is not so easy to judge the exact identy of your Pseudobagrus, even for a seasoned specialist! You can refer to the newly published "[b]Fishes of the World[/b]" 4th edition, for a general description of this group of fishes, if a further konwledge is dictated, another comprehensive monograph by Mo. T. may be helpful. http://as.wiley.com/WileyCDA/WileyTitle/productCd-0471250317.html Mo, T: [b]Anatomy, relationships and systematics of the Bagridae (Teleostei: Siluroidei)-with a hypothesis of siluroid phylogeny[/b].

沒錯滿實用的
-- 作者: hero8479 是短臀為尾
-- 作者: 尖嘴仔車栓子 三角哥~我釣到的數量很多~不過我都釣到ㄉ幾乎是黃色種ㄉㄟ!也因為他本身ㄉ體型不大所以我都釣起來就放生居多~黑色種類我在石岡壩釣到時還以為是小土虱仔哩!後來才知道是不同顏色而已!
-- 作者: 台灣鬥魚王 看地點~地點比例
-- 作者: 台灣白魚痴 這種魚危類的分辨的確是高難度的.不過我想知道的台灣這種魚危有幾種呢?有人說兩種 也有人說三種總之先了解在台灣到底有幾種呢?如何由型態分辨呢?
-- 作者: hero8479 以個人潛見大概分為三個型..以圖片這隻的背鰭 來看比較短.這隻是短臀峗.背鰭脫比較長身體也長.是脂峗貝鰭退化識有識無是臺灣鮰

參照台灣淡水與河口魚類誌

我印象中好像是要數臀鰭上面鰭棘的數量吧 錯了別打我~~~
