Abstract
ABSTRAKPenelitian ini bertujuan untuk menggambarkan struktur komunitas ikan pada areal
budidaya rumput laut secara long line di Teluk Ekas Lombok Timur. Metode yang
digunakan adalah metode survei dengan menggunakan jaring sapu. Teknik pengambilan data
teknik removal sampling. Analisis data untuk menggambarkan struktur komunitas ikan
adalah analisis secara diskriptif pada parameter jumlah jenis ikan, kemelimpahan,
keanekaragaman, keseragaman, dan dominansinya. Hasil analisis menunjukkan bahwa
jumlah spesies yang diperoleh sebanyak 886 yang terdiri dari 19 spesies. Spesies ikan yang
paling melimpah adalah Apogon angustatus diikuti oleh Achreichtys tomentosus dan Histrio
histrio. Indeks keanekaragaman spesies termasuk kategori sedang. Sedangkan indeks
keseragaman kategori tinggi dan dominansi berada pada katagori rendah. Kesimpulan dari
penelitian ini dimana indeks keanekaragaman spesies ikan pada areal budidaya rumput laut di
perairan Teluk Ekas secara keseluruhan sebesar 2,55. Nilai keanekaragaman tersebut dapat
menunjukkan bahwa rumput laut memiliki peran yang cukup besar dalam meningkatakan
jumlah jenis ikan di lokasi studi.

ABSTRACT
A research on fish community structure in the area of long line seaweeds mariculture of Ekas
bay East Lombok was done. Samplings of fish were conducted during September and October
2011. Removal sampling technique was applied in this research. Sample of fishes were
identified and analyzed for density, diversity, equitability or evenees, and domiancy. Total
886 fishes collected were identified as 19 species. Three species with the highest density were
Apogon angustatus, Achreichtys tomentosus, and Histrio histrio. Species diversity index of
fish in Ekas bay was in intermediate category. Furthermore, species index equitability or
evenees and dominancy were high and low category, respectively. This means there was no
fish species dominated other species. All 19 species of fish recorded in this research were in
relative similar number of individual.
Key Words: community structure, fish, seaweeds, Ekas bay
