Abstract

A total of 4 pelagic eggs and 24 larval fish species were collected in Masan Bay. Engraulis japonicus eggs predominated in pelagic eggs. Abundant larval fishes were Omobranchus elegans, Scomber japonicus, Acanthogobius flavimanus, Hexagrammos otakii, Repomucenus sp., Scartella cristata and Gobiidae sp., and these 7 species accounted for 78.5% in the total number of individuals. Temporal and spatial variation in both species composition and abundance of was large: the peak abundances of pelagic eggs and larval fishes occurred in July 2007, whilst these were lowest in February 2007. Higher abundance of ichtyoplankton were at station 5 than those of other stations. Temporal changes in the abundances of pelagic eggs and larval fishes corresponded with temperature. Pelagic eggs and larval fishes varied among stations between with shallower inner stations and deeper outer stations with physical characteristics such as depth and local topography.

조사기간 동안 총 4종의 부유성 어란과 24종의 자치어가 마산만에서 채집되었다. 어란의 우점종은 멸치 (Engraulis japonicus) 어란이었다. 그러나 자치어는 앞동갈베도라치 (Omobranchus elegan), 고등어 (Scomber japonicus), 문절망둑 (Acanthogobius flavimanus), 쥐노래미 (Hexagrammos otakii), 돛양태류 (Repomucenus sp.), Scartella cristata, 망둥어과(Gobiidae sp.) 순으로 우점하였다. 이들 7종은 전체 출현개체수의 78.5%를 차지하였다. 어란과 자치어는 시공간적으로 큰 변동을 보였다. 어란과 자치어의 현존량은 2007년 7월에 가장 높았으며, 2007년 2월에 가장 낮았다. 그리고 난자치어는 다른 정점에 비해 정점 5에서 현존량이 높았다. 어란과 자치어 현존량의 시간적 변화는 수온에 영향을 받았다. 부유성 어란과 자치어는 수심, 지형 등과 같은 물리적 환경 요인에 따라 좀 더 얕은 만 안쪽 정점과 깊은 만 외곽 정점 간 군집 차이를 보였다.
