Pengaruh Jarak Waktu Pemberian Kejutan Dingin pada Pembentukan Individu Triploid Ikan Patin (Pangasius Sp)
Abstract: The aim of this
study was to know the effect of temperature shock gift time distance from
fertilization on the triploidy individual process, persentage of hatching rate
and survival rate of larva patin catfish. Temperature shock gift time distance
treatment from fertilization process is given each 120 second, 180 second, 240
second and 300 second in temperature 40C during 90 second. Each treatment is
done as much as 3 times. Hatch and larva maintenance is done in aquarium and
hapa for fingerling activity. The result shows that temperature shock gift time
distance treatment from fertilization process gives real result on the
triploidy individual procces in patin catfish (p<0,05). Highest percentage
triploidy individual is got in temperature shock gift time distance from
fertilization process 180 second as big as 83,33 %. The growth level patin
catfish day 28 show enhanced in line with individual percentage enhanced
triploidy from each treatment. The highest growth rate is got from temperature
shock gift time distance treatment from fertilization process as big as 11,13
%.
