Abstract

This research aims to know the diversity of fish in seagrass at Padaratan Beach. This research was conducted in Pandaratan Beach, Sarudik Subdistrict, Central Tapanuli Regency from March until April 2018. Gill net is instrument to catch the fish at three determined stations. The diversity of fish can be assessed by looking the composition of fish species and index of diversity. The results of this study show 196 individuals, consist of 12 families and 14 species. The highest number of fish spesies at station II with total catch of 70 individuals. The most dominating fish species at all of stations is Zenarchopterus gilli with value of relative abundance in first station 22,96%, second station 20,01% and the last station 23,07%. The value of diversity index (H’) of all stations can be categorized in medium class of which score between 2,367-2,439. The value of equalibility index of all stations can be categorized in stable class of which score between 0,897-0,903, while for the value of domination index of all stations can be categorized in low class of which score between 0,102-0,127.Keywords ; Fish, Seagrass, Abundance, Diversity, Pandaratan Beach

Abstract

Seagrass beds are potential marine resources to be utilized, and ecologically, seagrass beds are some of the important functions of the coastal area. Many organisms are ecologically and biologically very dependent on the presence of seagrasses. The ecosystem is an important food source for the organism by many sea organisms that use it as a spawning place. This study aims to determine the diversity of fish in seagrass beds in Padaratan Beach, Sarudik Subdistrict, Central Tapanuli Regency. A gillnet is used to obtain fish samples at three observation stations during the period from mid-March to April 2018. Fish diversity can be agreed by looking at the composition of fish species and diversity index. The results of this study show the total number of fish obtained, 196 individuals, consisting of 12 families and 14 species. The highest number of fish catches is at Station II with a total catch of 70 individuals. The highest relative abundance of stations I, II, and III with values ​​of 22.96%, 20.01%, and 23.07% are found in fish species from the family Hemaramphidae with Zenarchopterus gilli species. The diversity index value (H') of all observation stations shows that species richness is in a moderate condition with values ​​of the station I (2,339), station II (2,439) and station III (2,367). While the uniformity value (e), shows the value of station I (0.866) station II (0.924) and station III (0.897) observations are in a stable condition (0.75 <e d ”1.00). Such conditions indicate that the distribution at each observation station is equitable.
