Korelasi kualitas air terhadap kinerja pertumbuhan benih ikan patin Pangasius hypophthalmus ukuran 1 inci di Balai Pengembangan Budidaya Air Tawar Subang

Abstract

The purpose of this study was to examine the correlation of water quality fluctuations in temperature, dissolved oxygen, and pH on the growth performance (length and weight) of catfish seeds size 1 inch at the age of 10, 20, and 30 days in Freshwater Aquaculture Development Center of Subang. The method used in this study are correlational type of field surveys to determine actual water quality conditions that affect fish growth performance. Water quality is correlated to the growth performance of catfish seeds is 10 days old the temperature ranged from 24.00 to 30.50°C, which inhibits the growth of seeds due to temperature fluctuations down 5.25°C within 4 hours. When seeds 20 days old, and the fluctuations ranged from 7.97 to 8.03 pH conditions favor the growth of the seeds. When seeds 30 days old, fluctuations in water quality not affect growth performance, presumably because body size is already relatively large seeds and has been able to adapt to changes in their environment.
