Abstract

The feeding ecology of the eight barbel loach, Lefua costata, were investigated in the Jusucheon (Stream), Namyang-ri, Okgye-myeon, Gangneung-si, Gangwon-do, Korea from January to December 2013. L. costata mainly fed from March to December when the water temperature was higher than 5℃, and the feeding rate peaked in April~May and September~October. Their main food organisms analyzed by the index of relative importance (IRI) were Diptera (77.1%), Ephemeroptera (20.3%), Trichoptera (1.7%) and Odonata (0.4%) in Insecta. Other food organisms were various, such as Arhynchobdellida (0.6%) and Tubificida (0.1%) of Annelida, Nematoda (0.2%), fish (Actinopterygii, 0.1%), and Veneroida (0.01%) of the Mollusca. Major seasonal food organisms were Diptera (55.4%) and Ephemeroptera (41.6%) in spring, Diptera (92.7%) and Anelida (6.8%) in summer, Diptera (70.8%), Ephemeroptera (9.0%), Trichoptera (8.1%) and Annelida (7.7%) in autumn. By age, juvenile (0+) tended to eat only Diptera (mainly Chironomidae, 98.2%) that were relatively small in prey size. However, as it grew, the proportion of Diptera gradually decreased, and the proportion of relatively large Mayflies and Annelids increased. The size of the prey organisms showed rapid growth, with 2.5±1.05 mm for juvenile (0+), 3.2±1.29 mm for one year (1+), 3.7±2.05 mm for two years (2+), and 6.8±4.97 mm for three years or more (≥3+).

쌀미꾸리 Lefua costata의 섭식생태를 밝히기 위해 2013년 1월부터 12월까지 강원도 강릉시 옥계면 남양리에서 조사를 실시하였다. 쌀미꾸리는 주로 수온 5℃ 이상 되는 3월부터 12월까지 섭식을 하였고, 섭식률은 4~5월, 9~10월에 정점을 보였다. 위 내용물을 상대중요성지수(IRI)로 분석한 결과, 주로 절지동물문(Arthropoda) 곤충강(Insecta)의 파리목(Diptera, 77.1%), 하루살이목(Ephemeroptera, 20.3%), 날도래목(Trichoptera, 1.7%), 잠자리목(Odonata, 0.4%)이었으며, 그 외 먹이생물은 환형동물문(Annelida)의 턱거머리목(Arhynchobdellida, 0.6%)과 실지렁이목(Tubificida, 0.1%), 선형동물문(Nematoda, 0.2%), 어류(Actinopterygii, 0.1%), 연체동물문(Mollusca)의 백합목(Veneroida) 등 다양하였다. 계절별로 보면, 봄에는 파리목(55.4%)과 하루살이목(41.6%)을, 여름에는 파리목(92.7%)과 환형동물문(Annelida, 6.8%)을, 가을에는 파리목(70.8%)과 하루살이목(9.0%), 날도래목(8.1%), 환형동물문(7.7%)을 주로 섭식하였다. 연령별로 보면 당년생 치어(0+)는 비교적 먹이 크기가 작은 파리목(주로 깔따구과(Chironomidae), 98.2%)만 거의 섭식한 반면, 성장하면서 파리목의 비율이 점점 감소하고 비교적 크기가 큰 하루살이목과 환형동물문의 비율이 증가하였다. 먹이 생물 크기는 당년생 치어(0+) 2.5±1.05 mm, 1년생(1+) 3.2±1.29 mm, 2년생(2+) 3.7±2.05 mm, 3년생 이상(≥3+) 6.8±4.97 mm로 성장하면서 급격히 커지는 경향을 보였다.
