Abstract

This study was conducted to determine the effect of hardness on growth and survival rate of barb fish (Barbus conchonius Hamilton-Buchanan) reared in the 3 ppt of water salinity.  Fish were reared in three different hardnesses, i.e., 54, 72,and 90 mg/L CaCO3 for 30 days.  The results of study showed that fish reared in water hardness of 72 mg/L CaCO3 had higher daily growth rate (1.15%) compared with other treatments.  Daily growth rate of fish reared in water hardness of 54 and 90 mg/L CaCO3 were 0.76 and 0.37%, respectively.  There was no effect of hardness on survival rate of barb fish.

Keywords: barb fish, Barbus conchonius,  hardness, salinity

 

ABSTRAK

Penelitian ini bertujuan untuk mengetahui pengaruh kesadahan yang berbeda terhadap laju pertumbuhan dan tingkat kelangsungan hidup ikan barbir (Barbus conchonius Hamilton-Buchanan) yang dipelihara pada air bersalinitas 3 ppt.  Ikan dipelihara dalam 3 tingkat kesadahan yang berbeda, yaitu 54 mg/L CaCO3, 72 mg/L CaCO3,dan 90 mg/L CaCO3 selama 30 hari.  Hasil penelitian menunjukkan bahwa laju perumbuhan harian tertinggi diperoleh pada ikan yang dipelihara pada kesadahan 72 mg/L CaCO3 (1,15%) dibandingkan dengan perlakuan lainnya. Laju pertumbuhan harian ikan yang dipelihara pada kesadahan 54 dan  90 mg/L CaCO3 masing-masing mencapai 0,76% dan 0,37%.  Kelangsungan hidup ikan barb tidak dipengaruhi oleh kesadahan.

Kata kunci: ikan barbir, Barbus conchonius, kesadahan, salinitas
