STATUS TERKINI DAN ALTERNATIF PENGELOLAAN SUMBER DAYA IKAN DI LAGUNA SEGARAANAKAN, CILACAP
Laguna Segara Anakan mempunyai peran penting sebagai kawasan pengelolaan perikanan udang sebagai daerah asuhan. Penyempitan dan pendangkalan perairan laguna sangat mempengaruhi populasi larva dan juvenil udang. Tujuan penulisan ini adalah untuk mengkaji hubungan perubahan lingkungan terhadap sumberdaya udang. Kandungan oksigen terlarut relatif rendah, kondisi tersebut dalam jangka panjang akan berpengaruh terhadap laju pertumbuhan ikan dan udang, dan akhirnya berdampak langsung terhadap laju rekruitmen udang dan ikan untuk perairan Segara Anakan dan perairan laut sekitar Cilacap. Kelimpahan larva udang dan ikan di perairan laguna ini berkisar antara 87 – 63,451 ind./1000 m3, dan kelimpahan juvenil tersebut berkisar antara 0 – 25,263 ind./1000 m2, dimana selama pengamatan didominasi oleh juvenil udang. Total produksi (ikan dan udang) di Segara Anakan dari tahun ke tahun mengalami penurunan yang signifikan dalam periode tahun 1987-2004. Kondisi tersebut disebabkan luas perairan laguna semakin sempit dan dangkal, serta intensitas penangkapan semakin tinggi. Oleh karena itu, perlu suatu pengelolaan yang menyeluruh terhadap sumber daya laguna agar mampu mengurangi laju penurunan produksinya, yaitu pengelolaan sumberdaya perikanan di laguna Segara Anakan sebagai satu kesatuan ekologi yang utuh.Segara Anakan lagoon have an important role as the shrimp fishery management area in which shrimp species using this area of lagoons as a nursery ground.
