PENGARUH PADAT TEBAR TERHADAP PERTUMBUHAN DAN KELULUSHIDUPAN BENIH IKAN PATIN SIAM (Pangasius hypophthalmus) PADA SISTEM AKUAPONIK
ABSTRACT: This research was
conducted on April to May 2017 in the Hatchery of TIU (Technical Implementation
Unit) of Aquaculture Department, Marine and Fishery Faculty, Riau University,
Riau Province. The aimed of this study was to know the effect of different fish
stocking density toward the growth performance and survival rate of the Siamese
shark fry on the aquaponics system. The method was using the experimental
method with five treatment levels and three repeating (fifteen treatment
units). The treatments were 30 fries/tank of fish stocking density (P1); 40
fries/tank of fish stocking density (P2); 50 fries/tank of fish stocking
density (P3); 60 fries/tank of fish stocking density (P4); and 70 fries/tank of
fish stocking density (P5). The material was 750 fries of Siamese shark with
the size around 5-7 cm and it was reared for 45 days long. The results shown
that the best treatment was in 60 fries/tank of fish stocking density (P4) or
equivalent with 240 fishes/m2, and its absolute weight growth was 4.81 gram,
absolute length growth 3.62 cm, specific growth rate 3.44 %, food efficiency
86.21 %, fresh plant weight (FPW) was 30.64 gram. Treatment by using a
different fish stocking density had the same survival rate for all treatments that
was 100%.
