Abstract

The feeding habits of Boleophthalmus pectinirostris were studied using 198 specimens collected monthly from April 2014 to March 2015 in the intertidal zone of Beolgyo, Korea. The size of B. pectinirostris ranged from 6.5 to 18.7 cm in total length (TL, cm). B. pectinirostris was herbivore that consumes mainly centric and pennate diatoms. Its diets also included small quantities of Prorocentrum dinoflagellates. and nematods. B. pectinirostris predominantly consumed diatoms (mainly Pleurosigma spp., Navicula spp., Nitzschia spp., Gyrosigma spp.) in all fish size classes, and all months, and thus there were no significant diet changes in relation to size and month.

본 연구는 2014년 4월~2015년 3월까지 순천시 벌교읍 호동리의 개펄 조간대에서 출현하는 짱뚱어 Boleophthalmus pectinirostris 198개체를 대상으로 식성을 조사하였다. 짱뚱어의 전장은 6.5~18.7 cm의 범위를 보였다. 짱뚱어는 규조류를 주로 섭식하는 초식성이었다. 와편모조류, 선형동물 등도 섭식하였지만 그 양은 적었다. 짱뚱어는 모든 크기군과 계절에서 규조류 (주로 Pleurosigma spp., Navicula spp., Nitzschia spp., Gyrosigma spp.)를 많이 섭식하였다.
