Pengaruh Perbedaan Suhu Terhadap Perkembangan Embrio, Daya Tetas Telur Dan Kecepatan Penyerapan Kuning Telur Ikan Black Ghost (Apteronotus Albifrons) Pada Skala Laboratorium

Abstract

Black ghost is one of the prospective ornamental fish export commodities which have fish economic value. These fish prefer waters with range temperature of 26-28 0C. The method used was experimental laboratories with design used Randomized Design Complete with 4 (four) treatment temperature of 24, 26, 28 and 30 0C and 3 (three) replicated whose have been conducted on 19 March to 4 May 2012 at Research and Development Center Aquaculture Freshwater Ornamental Fish Depok, West Java. The results obtained which the longest embryonic development was the fastest time of the treatment temperature is 30 0C (55 hours 56 minutes). Hatching Rate (HR) is the highest percentage is 26 0C temperature treatment was 36%. The speed of absorption of the yolk of the fastest time was 30 0C temperature treatment (4 days 21 hours). The results of Hatching Rate showed that the spread of data obtained normal with a significant value 0,932 and homogeneous 0,848. ANOVA of the data can be seen that F calculated was 3,167 and F table was 4,07. Since F calculated <F table, then H0 is accepted. It means that water temperatures does not directly influence hatching rate black ghost fish larvae
