초록

본 연구는 동해 남부 연안에서 출현하는 도화망둑 (Amblychaeturichthys hexanema)과 수염문절 (A. sciistius)의 위 내용물을 분석하여 두 어종의 위 내용물 조성을 조사하고, 종 간 그리고 성장에 따른 먹이자원의 분할이 있는지 연구하였다. 도화망둑과 수염문절은 저서성 갑각류를 주로 섭식하는 저서 섭식 육식성어류였다. 저서성 무척추동물과 부유성 먹이 또한 각각 도화망둑과 수염문절의 먹이로써 중요도가 다소 높았다. 중량비 자료를 이용한 non-metric multidimensional scaling (nMDS)와 다변량 분석 (multivariate analyses)에서 두 어종의 위 내용물 조성은 그 차이가 유의하였다. 그러나 두 어종 모두 성장에 따른 위 내용물 조성 변화에서 차이가 유의하지 않았다. 두 어종이 섭식한 먹이생물의 차이는 섭식 행동의 차이와 관련있다. 결론적으로, 본 연구해역에서 두 어종의 위 내용물 분석 결과는 도화망둑과 수염문절 사이에 생태지위 분리의 증거와 먹이 자원에 대한 종 간 경쟁 감소의 가능성을 보여주었다.

Stomach contents of Amblychaeturichthys hexanema and A. sciistius (Perciformes: Gobiidae) from southeastern waters off Korea were analyzed to determine dietary habits and the presence of any inter- and intra-specific partitioning of food resources. These two species were bottom-feeding carnivores that consumed mainly benthic crustaceans, and other demersal invertebrates and planktonic organisms were also important in their diets. Non-metric multidimensional scaling (nMDS) ordination and multivariate analyses based on gravimetric contributions of the different prey taxa to stomach contents revealed significant inter-specific dietary differences; i.e. partitioning of food resources between the two species. Size-related changes, however, were not significant for their diets. Differences in the types and range of prey ingested by the two species could often be related to differences in the feeding behaviors. Our results of stomach contents analyses provide clear evidence of niche segregation between co-occurring A. hexanema and A. sciistius in southeastern Korean waters, which would reduce the likelihood of inter-specific competition for food resources.
