Abstract
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. Refinement and siltation of the lagoon waters greatly affect populations of larvae and juvenile shrimp. The purpose of this paper is to study the relationship of environmental change on shrimp resources. Dissolved oxygen is relatively low, the condition will affect the growth of fish and shrimp in the long time, and ultimately it have a direct impact on the rate of recruitment of shrimp and fish for Segara Anakan waters and coastal waters around Cilacap. Abundance of larval shrimp and fish in this lagoon waters ranged from 87 to 63.451 ind./1000 m3 and the juvenile abundance ranged from 0 to 25.263 ind./1000 m2, where the observations are dominated by the juvenile shrimp. Total production (fish and shrimp) at Segara Anakan from year to year has decreased significantly over the period 1987-2004. The condition is caused by the broad waters of the lagoon is narrow and shallow, and the higher the intensity of fishing. Therefore, the need for a comprehensive management of the lagoon resources in order to reduce the rate of decline in production, the management of fishery resources in the lagoon Segara Anakan as a whole complete ecology.
