Abstract

A study of larval fishes in an area of seagrass beds at Salut Lagoon, Karambunai was conducted with three objectives: To identify the fish larvae family in the seagrass beds; to study the abundance and diversity of fish larvae in the study area; compare the result in both stations. Light trap were deployed at two stations for three consecutive nights for three month starting August 2004 until October 2004. Station I was an area of seagrass beds near mangroves area. Station 2 was an area of seagrass beds which is far from mangrove area. Altogether 297 fish larvae were caught for the whole sampling. Larvae of 10 families were captured of which Ambassidae was the most abundant. This was followed by Gobiidae (n=75), Atherinidae (n=30), Engraulidae (n=24), Leiognathidae (n=17), Synodontidae (n=7), Belonidae (n=6), Terapontidae (n=6), Eleotrididae (n=4) and Lethrinidae (n=4). There were 8 families found in station 2, which does not include Belonidae and Eleotrididae. Fish larvae captured on area of seagrass beds near to mangrove were higher (n=196) compare to the area of seagrass beds alone (n=101). By using the Shannon-Weaver Diversity Index (H'), the estimates value for diversity, evenness and richness among fish larvae was found higher in station 1 compared to station 2 but the independent t-test showed no significant difference in diversity estimate value for both area (p > 0.05). This may be due to the close distance between stations.
