Lele dumbo (C. gariepinus) merupakan ikan yang bersifat nokturnal. Cahaya
mempengaruhi periode aktif ikan lele dalam mencari makan, periode aktif ikan
lele dalam mencari makan akan mempengaruhi laju pertumbuhan. Penelitian
bertujuan untuk mengetahui pengaruh fotoperiode terhadap pertumbuhan ikan lele
dumbo. Penelitian mengunakan Rancangan Acak Lengkap (RAL) dengan
perlakuan 5 fotoperiode yang berbeda dan 3 ulangan. Perlakuan yang diberikan
adalah A (6 jam terang dan 18 jam gelap), Perlakuan B (12 jam terang dan 12 jam
gelap), perlakuan C (18 jam terang dan 6 jam gelap), D (24 jam gelap dan 0 jam
terang) dan E (0 jam terang dan 24 jam gelap). Hasil uji ANOVA menunjukan
bahwa fotoperiode berpengaruh nyata terhadap pertumbuhan berat dan panjang,
namun tidak berpengaruh nyata terhadap Survival Rate (SR). Hasil penelitian
menunjukan bahwa semakin lama waktu gelap maka pertumbuhan semakin tinggi.
Pertumbuhan berat dan panjang tertinggi terjadi pada perlakuan E (24G;0T)
dengan rata-rata mencapai 1,989 gram, dan rata-rata pertumbuhan panjang
mencapai 7,044 cm.
Kata kunci : Lele dumbo, fotoperiode, dan pertumbuhan rata-rata.



Abstract

African catfish is a nocturnal fish (C. gariepinus). Active period of foraging
might effect the growth rate of catfish. The aim of the study was to determine the
effect of photoperiod on the growth of African catfish. Complete Randomized
Designed (CRD) was assigned on the research which consist of 5 different
photoperiod treatments namely A (6 hours light and 18 hours dark), B (12 hours
light and 12 hours dark), C (18 hours light and 6 hours dark), D (24 hour dark and
light 0 hours), and E (0 hours of light and 24 hours dark) and 3 replications for
each treatment. ANOVA test results showed that photoperiod significantly effect
the weight and length growth, but not significantly effect on Survival Rate (SR).
The results showed that the longer dark period the higher the growth. Weight and
length growth was highest in treatment E (24 hours dark end 0 hours light) with
average weight of 1.989 gram, and with average growth of 7.044 cm long.
Key words: African catfish, photoperiod and growth rate.}
