| Summary: | <p>This study was conducted to determine the effect of hardness on growth and survival rate of barb fish (<em>Barbus conchonius</em> Hamilton-Buchanan) reared in the 3 ppt of water salinity. Fish were reared in three different hardnesses, i.e., 54, 72,<sub> </sub>and 90 mg/L CaCO<sub>3 </sub>for 30 days. The results of study showed that fish reared in water hardness of 72 mg/L CaCO<sub>3</sub> 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 CaCO<sub>3</sub> were 0.76 and 0.37%, respectively. There was no effect of hardness on survival rate of barb fish.</p> <p>Keywords: barb fish, <em>Barbus conchonius</em>, hardness, salinity</p> <p> </p> <p>ABSTRAK</p> <p>Penelitian ini bertujuan untuk mengetahui pengaruh kesadahan yang berbeda terhadap laju pertumbuhan dan tingkat kelangsungan hidup ikan barbir (<em>Barbus conchonius</em> Hamilton-Buchanan) yang dipelihara <a name="OLE_LINK2"></a><a name="OLE_LINK1">pada air bersalinitas 3 ppt. </a>Ikan dipelihara dalam 3 tingkat kesadahan yang berbeda, yaitu 54 mg/L CaCO<sub>3</sub>, 72 mg/L CaCO<sub>3</sub>,<sub> </sub>dan 90 mg/L CaCO<sub>3 </sub>selama 30 hari. Hasil penelitian menunjukkan bahwa laju perumbuhan harian tertinggi diperoleh pada ikan yang dipelihara pada kesadahan 72 mg/L CaCO<sub>3 </sub>(1,15%) dibandingkan dengan perlakuan lainnya. Laju pertumbuhan harian ikan yang dipelihara pada kesadahan 54 dan 90 mg/L CaCO<sub>3</sub> masing-masing mencapai 0,76% dan 0,37%. Kelangsungan hidup ikan barb tidak dipengaruhi oleh kesadahan.</p> <p>Kata kunci: ikan barbir, <em>Barbus conchonius</em>, kesadahan, salinitas</p> |
