Hubungan Kerapatan Mangrove terhadap Kelimpahan Ikan Glodok (Boleophthalmus boddarti) di Baro Gebang, Cirebon

Abstract

Penelitian ini menganalisis hubungan antara kerapatan mangrove dan kelimpahan ikan glodok (Boleophthalmus boddarti) di pesisir Baro Gebang, Cirebon. Pengambilan data dilakukan Januari 2026 pada tiga stasiun dengan kerapatan berbeda (tinggi, sedang, rendah). Kerapatan mangrove diukur menggunakan metode transek 10×10 m dan plot. Ikan glodok dikumpulkan saat surut dengan transek 10×10 m. Analisis menggunakan korelasi Pearson. Hasil menunjukkan kerapatan mangrove tertinggi di Stasiun 2 (2.500 ind/ha anakan), terendah di Stasiun 3. Jenis Avicennia marina mendominasi seluruh stasiun. Kelimpahan ikan glodok tertinggi di Stasiun 2 (844,44 ind/ha) dan terendah di Stasiun 3 (300 ind/ha). Korelasi Pearson menunjukkan hubungan sangat kuat dan positif (r = 0,9997), artinya semakin tinggi kerapatan mangrove, semakin tinggi kelimpahan ikan glodok. Faktor oksigen terlarut, kekeruhan, dan tekanan antropogenik juga berpengaruh.

This study analyzed the relationship between mangrove density and mudskipper (Boleophthalmus boddarti) abundance in Baro Gebang, Cirebon. Data were collected in January 2026 at three stations with different density levels (high, moderate, low). Mangrove density was measured using transect 10×10 m and plot methods. Mudskippers were collected during low tide using 10×10 m transects. Pearson correlation was used for analysis. Results showed the highest mangrove density at Station 2 (2,500 ind/ha for saplings) and the lowest at Station 3. Avicennia marina dominated all stations. The highest mudskipper abundance was at Station 2 (844.44 ind/ha) and the lowest at Station 3 (300 ind/ha). Pearson correlation revealed a very strong positive relationship (r = 0.9997), indicating that higher mangrove density corresponds to higher mudskipper abundance. Dissolved oxygen, turbidity, and anthropogenic pressure also influenced abundance.
