地理的範囲

Taiwan, located off the southeastern coast of the Asian continent and on the western edge of the Pacific Ocean, lies between Japan and the Philippines, positioned at the central point of the East Asian island arc. It serves as a critical hub for maritime and air transportation in the Asia-Pacific region. Covering a total area of approximately 36,000 square kilometers (14,400 square miles), Taiwan is characterized by a narrow east-west span and an elongated north-south axis.

プロジェクトデータ

The primary goal of this study is to compile and assess the current status of freshwater fish species in Taiwan's natural freshwater ecosystems. This involves reviewing survey reports and literature on freshwater fish in Taiwan's lakes, ponds, streams, rivers, and offshore islands. Additionally, a three-year comprehensive survey of freshwater fish resources will be conducted starting from 2009. This effort will include species assessments and analyses for the Red List, as well as the drafting and publication of the Red List. Supplemental field investigation data will also be integrated to establish a database encompassing the current status of freshwater fish ecology and related information. Item : 1. Complete the investigation and assessment of freshwater fish resources in Taiwan's native lakes and ponds, as well as in the freshwater ecosystems of its offshore islands. 2. Conduct in-depth supplementary field surveys and evaluations of stream fish species in Taiwan that require urgent conservation efforts. 3. Photograph the surveyed fish species that currently inhabit freshwater environments, capturing their ecology, habitats, and features for identification purposes (e.g., providing male and female photos if morphological differences exist). For species no longer present, provide specimen photos; if no specimens are available, include relevant explanations. 4. Compile data from the past two years of supplementary surveys to complete the drafting of Taiwan's freshwater fish Red List. This will include producing an electronic version for online access and printing 2,000 physical copies. Additionally, integrate data from the previous field surveys to establish an ecological status database for the Red List and related fish species. 本研究的總目標將以針對台灣純淡水域的魚類自然生態物種資源現況，彙整台灣地區湖泊及野塘與溪流、河川及離島淡水魚類之相關調查報告與文獻，並自2009年起進行為期三年的淡水魚類資源現況普查工作，以及紅皮書之淡水魚種評定分析，並且完成紅皮書之相關撰寫及編印，野外補充資源調查資料之整合，構建出紅皮書與相關淡水魚類生態資訊現況資料庫。 工作項目： 1.完成台灣本土之湖泊及野塘的淡水魚種資源現況與各離島淡水魚類的調查及資源評析。 2.針對淡水魚類中，較為需要保育現況深入作調查的溪流魚類之魚種，作深入地台灣地區的野外溪流補充調查及現況評析。 3.拍攝所調查現存於淡水域之魚種生態、棲地及鑑定用(如外形因性別之不同，應提供雄雌相片)相片；已不存在之魚種，提供標本相片，若無標本相片，則撰寫相關說明。 4.彙整前兩年來的相關補充調查，完成台灣淡水魚類的紅皮書之相關撰寫及網路電子版及書籍編印(2000本)，並依據前兩年的野外補充調查資料之整合，構建紅皮書與相關魚種之生態現況資料庫。

収集方法

This project encompasses a total of 147 sampling sites. Each sampling site is surveyed once during the investigation period. 本項目共涵蓋147個採樣點，每個採樣點在調查期間進行一次調查。

Method step description:

1. Observing Fish Breeding Periods Through shoreline and snorkeling observations, the study aims to identify the timing of the appearance of larval and juvenile fish in the wild and to document courtship or spawning behaviors of dominant wild fish populations. These observations will help infer the reproductive characteristics of specific fish species, providing essential references for future freshwater fish ecological conservation efforts and reproductive biology studies. 觀察魚類繁殖期 利用沿岸及浮潛觀察的方式，瞭解野外現地的優勢魚類野生族群之仔稚魚出現期以及魚類求偶或產卵繁殖行為之記錄，以為能推算其特定魚種的繁殖特性，作為未來淡水魚類生態保育工作，與其之生殖生物學的重要參考依據。
2. Measuring Hydrological Environmental Factors The study records the substrate characteristics of surveyed habitats to understand the relationship between species occurrence frequency and substrate properties. Within the survey areas, three sampling points are randomly selected at the water surface layer. At these points, key water quality parameters are measured: Water temperature (using a Conductivity Meter), Conductivity (using a Conductivity Meter), Total dissolved solids (TDS) (using WTW-LF330), Turbidity (using a Turbidity Meter, AQUALYTIC PC Compact), and pH (using a pH Meter, Suntex TS-1). These measurements provide a detailed analysis of water quality factors in the surveyed environments. 測定水文環境因子 記錄調查棲所的底質環境特性，並瞭解物種出現頻度與底質特性的相互關系。於調查樣區中，任選水表層之三個採樣點，以 Conductivity Meter測量現場的1水溫（ Water Temperature）、導電度 （ Conductivity）、總懸浮固體量（ TDS,WTW-LF330）；並以濁度計來測量水中濁度值 ( Turbidity， AQUALYTIC PC Compact)；以 pH Meter測量酸鹼值（ pH，Suntex TS-1）等水質環境因子。
3. Standard Operating Procedure for Stream Freshwater Fish Field Surveys There are various methods for collecting freshwater fish, including shoreline observation, snorkeling, netting, bait trapping, electrofishing, and angling in streams, rivers, lakes, and ponds. Among these, electrofishing and cast netting have become the most commonly used methods in Taiwan in recent years due to their high efficiency and convenience in capturing fish within shallow waters (up to 1 m deep) along shorelines. However, in slow-flowing or stagnant habitats such as lakes and ponds, these methods often require supplementation with other techniques, particularly trap fishing, to achieve a more comprehensive survey of fish communities. Angling, on the other hand, introduces significant selection bias toward specific species and is therefore not recommended as part of the standard operating procedures for field surveys. In the 2010 survey, stream habitats were the primary focus, with electrofishing serving as the main method for freshwater fish ecological studies. Additional collection methods listed were applied as needed, depending on specific circumstances. 使用溪流淡水魚類野外調查標準作業流程 淡水魚類之採集方法有許多種不同的方式，溪流、河川、湖泊及野塘的岸邊觀察、浮潛觀測、網捕法、誘捕法、電魚法及垂釣法。在這些方法中，「電魚法」與「手投網網捕法」因其高效率與便利性，特別是在水深達1公尺的淺水岸邊捕魚，近年來已成為台灣最常使用的方法。然而，在如湖泊及池塘等水流緩慢或停滯的棲地中，這些方法往往需要其他技術的補充，特別是「魚籠誘捕法」才能具備更完整之魚類群聚調查。其中垂釣法對調查魚種選擇度較有明顯偏差，因此暫不列入野外標準作業流程之建議方法。2010年度調查以溪流的棲地為主，大多採用「電魚法」進行淡水魚類生態調查的主要方法，並將再視情況輔以其它所列出之採捕方式進行。
