Anodonta Woodiana

Kijing Taiwan (Anodonta woodiana) termasuk salah satu jenis kerang air tawar yang telah dikonsumsi oleh masyarakat. Salah satu bahan pencemar yang sering terdapat pada hewan filter feeder seperti kijing adalah logam berat. Logam-logam berat berbahaya yang sering mencemari lingkungan antara lain merkuri (Hg), cadmium (Cd), dan timbal (Pb). Tujuan penelitian ini adalah mengetahui kandungan logam berat Hg, Cd, dan Pb daging Kijing Taiwan selama periode dua bulan (Maret dan Mei) serta menerapkan perlakuan depurasi sebagai usaha untuk mengurangi kandungan logam berat. Penelitian dilakukan dengan cara mengiventarisasi wilayah pengambilan sampel, analisis karakteristik kijing, melakukan depurasi, dan analisis kandungan logam berat Hg, Cd, dan Pb daging kijing. Sampel Kijing Taiwan diambil dari perairan Darmaga di, Bogor. Kandungan proksimat daging kijing yang diukur adalah kadar air 81,5%, protein 8,9%, lemak 1,0%, abu 3,1%, dan karbohidrat 5,4%. Rendemen daging kijing sebesar 20,1% (sebelum depurasi), 19,6% (setelah 10 hari depurasi), dan 18,9% (setelah 20 hari depurasi). Kijing Taiwan di perairan Darmaga menunjukkan kandungan logam berat merkuri dan kadmium yang sangat kecil pada daging selama periode dua bulan (Maret dan Mei). Kandungan timbal bulan Maret lebih tinggi dibandingkan bulan Mei. Rata-rata kandungan timbal di perairan Darmaga selama dua periode adalah sebesar 1,4 ppm. Perlakuan depurasi selama 20 hari dapat menurunkan kandungan timbal pada kijing sebesar 0,05 ppm (setelah 10 hari depurasi) dan 0,08 ppm (setelah 20 hari depurasi).Kata kunci: Anodonta woodiana, Cd, depurasi, Hg, perairan Darmaga, Pb.

A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.
