Description

Kikuchi minnow (Aphyocypris kikuchii) is an endemic freshwater fish distributing in the eastern Taiwan, but it faces the threat of abundance declining and distribution range decreasing. Tse-Xin Organic Agriculture Foundation promotes Green Conservation of rice fields in Nan’an, Zhuoxi Township, Hualien County, and stumbled on Kikuchi minnow in 2016. The purpose of this survey is to understand the abundance and distribution of Kikuchi minnow and the relationship with the environment of paddy fields. The survey started from March 2017 to December 2018, and conducted twice a month with fish cages. This survey has obtained 572 records from 7 monitoring sites. 菊池氏細鯽(Aphyocypris kikuchii)為臺灣特有種魚類,過去分布遍及臺灣東部且數量頗豐富,近年來數量與分布大幅縮減。慈心基金會在2016年花蓮縣卓溪鄉南安地區推動水稻田的綠色保育時,意外發現菊池氏細鯽。為瞭解南安地區菊池氏細鯽族群數量、分布現況,以及與水稻田耕作環境的關連性,進行本項調查。調查時間自2017年3月至2018年12月,設置7個監測樣站,每月調查2次,以方型魚籠及自製餌料誘捕,共累積572筆紀錄。

Sampling Methods

Set up 7 monitoring sites: 1. Channel: beside the No. 30 Provincial Road, is a concrete structure 2. FarmDitch: in a grit chamber, the water is about 20 cm deep 3. FarmPond: a pond formed of irrigation water, the water is about 1 m deep 4. ChannelGate: downstream of the Channel (#1), the water flow can be controlled by the gate 5. EndPond: at the end of soil ditch 6. ArtificialPool: excavated manually in January 2018, the pool is about 3.4 m long and 1.7 m wide, and the water depth is about 30 cm 7. Gate: an area that ChannelGate (#4) passing through the culvert of the provincial road, is a natural soil ditch 共設置7個監測樣站: 1.路邊大排:台30線省道旁排水溝,承接階地上整個水圳路、水溝及山溝水的匯入。為水泥構造,但底質因泥土淤積而有植被及高低落差。 2.田間水圳:階地上水泥水圳路的一段,樣站布置在一段雙L轉折區塊的兩個沈沙池,水深約20公分左右,上有柵欄覆蓋。圳路直線段會因淤積而有水生植物叢生。 3.田間池塘:階地上一段自然土溝圳路的尾端,承接周邊田區與圳路灌溉後退水而成池塘。與周邊田區以田埂區分,池塘周圍為雜草所覆蓋。水深估計約在1公尺左右。 4.大排閘門:#1樣站(路邊大排)往更下游處的排水溝,並且為#2樣站(田間水圳)匯入排水溝之處,此處可透過閘門運作控制水流穿過省道涵洞往更下游田區(#5樣站)。 5.尾水池塘:位於土溝圳路最末端之處,水位與承接的水圳水量有關。 6.生態水池:鄰近#2樣站水圳路末端,亦與#4樣站相鄰。為2018年1月人工挖掘的生態水池,長約3.4公尺,寬1.7公尺,水深與水圳路進水量有關,水深約30公分以上。 7.閘門尾水:為#4樣區(大排閘門)穿越省道涵洞之後排水之處,接續點後為土溝形式水圳,水路可一直延續到#5樣區(尾水池塘)。

Study Extent The survey started from March 2017 to December 2018, and conducted twice a month. Survey time period included morning and afternoon. Each site set up 2 fish cages with self-made bait, but sometimes only 1 cage was placed due to the limitation of water depth. Retrieved after 10 to 30 minutes, all captured individuals were measured for body length, total length and weight and returned to original places. Due to factors such as climate, personnel and survey adjustments, only 1 survey was conducted in May and November 2018, and 3 surveys were conducted in October 2017 and January 2018. 調查時間自2017年3月至2018年12月,每月調查2次,每次進行上午及下午兩個時段的調查,以方型魚籠及自製餌料誘捕,每個樣站放置2個魚籠(有時因樣站面積與水域深度限制,僅能放置1個),放置10-30分鐘後收回。所有捕抓到的個體皆記錄種類、體長、全長及體重後放回原處。因氣候、人員及調查調整因素,2018年5月、11月僅調查一次,2017年10月及2018年1月調查3次。
Quality Control The survey was conducted by the same surveyor, using the same fish cages (21cm*23cm*46cm). Recorded date, location, survey period in survey record form. If captured uncertain species, took pictures and confirmed by other experts later. 由固定人員以大小相同(約21cm*23cm*46cm)的魚籠調查,記錄調查日期、放置位置、魚籠數量、放置時間等,填寫於調查紀錄表。如遇到不確定的物種,則拍照記錄,再經其他專家協助確認辨識。

Method step description:

  1. 1. Each site set up 2 fish cages with self-made bait, but sometimes only 1 cage was placed due to the limitation of water depth. 2. Depending on the area and water depth, retrieved fish cages for 10 to 30 minutes. 3. All captured individuals were measured for body length, total length and weight and returned to original places. 1.每個樣站放置2個魚籠,有時因樣站面積與水域深度限制,僅能放置1個。 2.依照樣站面積與水深放置10-30分鐘後,收回魚籠。 3.將所有捕捉到的個體記錄種類、體長、全長、重量等,再將個體放回原處。
