Kuantifikasi Sisa Pakan Dan Sisa Metabolisme Di Karamba Jaring Apung (KJA) Waduk Cirata (Quantification Of Waste Of Food And Metabolism Remains At Floating-Net Cage Fisheries, Reservoir Of Cirata )

Penelitian mengenai kuantifikasi sisa pakan dan sisa metabolisme di Karamba Jaring Apung (KJA) Waduk Cirata telah dilakukan pada 1 November sampai 25 November 2013. Metode yang digunakan adalah metode eksperimental dengan Rangcangan Acak Lengkap (RAL) 3 perlakuan dan 3 ulangan. Perlakuan yang digunakan terdiri dari : A. frekuensi pemberian pakan sebanyak 3 kali, B. frekuensi pemberian pakan sebanyak 4 kali dan C. frekuensi pemberian pakan sebanyak 5 kali. Parameter utama yang diamati meliputi bobot sisa pakan dan sisa metabolisme, rasio konversi pakan dan laju pertumbuhan harian. Parameter penunjang yang diamati meliputi tingkat kelangsungan hidup dan kualitas air. Hasil penelitian menunjukkan bahwa perlakuan pemberian pakan dengan frekuensi yang berbeda tidak berbeda nyata terhadap laju pertumbuhan dan konversi pakan.Frekuensi Pemberian pakan sebanyak 4 kali menghasilkan laju pertumbuhan cenderung lebih tinggi sebesar 1,65% dengan rasio konversi pakan 1,04. Pemberian pakan sebanyak 3 kali menghasilkan sisa pakan dan sisa metabolisme paling rendah dengan nilai rata-rata sebesar 10,05 gram perhari.

Research about Quantification of waste of feed the fish and metabolism remains was conducted at floating-net cage fisheries in the reservoir of Cirata was begun from November 1st until November 25th 2013. This research used experimental method using Completely Randomized Design (CRD), with three treatments and three replications. The treatments were A. 3 times of feeding; B. 4 times of feeding; C. 5 times of feeding. The main parameters observed were weight of residual feed and metabolism, Food Conversion Ratio and daily growth rate. This research showed the result that a treatment of feeding within variety frequencies is not significant to growth rate and food conversion. Feeding within 4 times resulted growth rate tend to be higher 1,65% with Conversion ratio 1,04. The fewest waste was indicated by average value of 10,05 grams on improving the feeding frequency by 3 times.
