KOMPOSISI TUBUH DAN MODEL LIPOSTATIK IKAN BAWAL AIR TAWAR (Colossomamacropomum) YANG DIPUASAKAN SECARA PERIODIK
ABSTRACT: This important
principle used in feeding strategy is reducing feed input that does not impact
on fish growth. One of this strategy is periodic fasting. Fasting has done for
reducing over protein consumption and waste, but not inhibiting fish growth.
The change of body composition is one of growth indicator where the change of
body composition reflect in proksimate composition ie moisture, protein,
lipida, carbohydrate and mineral percentade that stated in ash of body.
Lipostatic model is also indicator to know compensatory growth. The aim of this
study was to investigate the effect of periodic fasting on body composition and
lipostatic model of Tambaqui (Colossoma macropomum). The method used in this
study was experiment based on completely randomized design consisting of
control K(feed daily) and two treatments ie: P1 (fish was unfed for 2 days and
5 days refeeding), P2 (fish was unfed for 3 days and 4 days refeeding). Five replicates
were provided for the control and the treatments. The variables observed were
body composition and lipostatic model. The experiments were conducted for 12
weeks. The result showed that Tambaqui received periodic fasting did not affect
moisture, protein content, fiber, ash and nitrogen free extract but affect
lipid content of body and lipostatic model of Tambaqui (Colossoma macropomum).
Keywords: Tambaqui (Colossoma
macropomum), periodic fasting, lipid content of body and lipostatic model
