STRUKTUR KOMUNITAS SUMBERDAYA IKAN PADANG LAMUN DI TELUK EKASLOMBOK TIMUR

Abstract

Abstract

Research on seagrass fishes resources condition was conducted in the intertidal zone of Ekas Bay, East Lombok. Sampling of fishes was conducted using the swept area method with beach seine. The result of this research in three station showed that the degree of fishes diversity was low. There was a strong indication that the fishes species in the research area were dominated by certain fish species. In general, the firtility of Ekas Bay coastal water was semilar with the other coastal waters, however the environmental condition mainly the low of persentage of seagrass covering in the research location was the main couse of the low diversity of seagrass fish of the area. High exploitation followed by destruction methods of exploitation can be the main causes of fish degradation habitat, mainly in the seagrass of Ekas Bay, East Lombok.

Abstrak

Penelitian kondisi sumberdaya ikan padang lamun telah dilakukan di wilayah intertidal Teluk Ekas, Lombok Timur. Pengambilan sampel ikan menggunakan metode swept area dengan pukat pantai (beach seine) di tiga stasiun pengamatan menunjukkan bahwa tingkat keanekaragaman ikan di lokasi penelitian rendah. Ada indikasi yang sangat kuat bahwa dominansi suatu jenis ikan di setiap stasiun pengamatan. Secara umum, kesuburan perairan Teluk Ekas relatif sama dengan perairan lainnya, namun kondisi lingkungan terutama persentasi penutupan padang lamun yang rendah menjadi penyebab utama rendahnya keanekaragaman ikan padang lamun di lokasi penelitian. Tingkat eksploitasi yang tinggi disertai dengan cara eksploitasi yang tidak mempertimbangkan kesinambungan pemanfaatan sumberdaya menjadi penyebab rusaknya habitat ikan, khususnya padang lamun di Teluk Ekas, Lombok Timur.
