PENGARUH PAKAN YANG BERBEDA TERHADAP PERTUMBUHAN BENIH IKAN GABUS (Channa gacua)
Abstract: The purpose of this
research was to know the suitable food for snake head fry rearing. This
research used experimental method with completely randomized design with three
treatment: A (used Artemia sp.), B (used Daphnia sp.) and C (used Tubifex sp.),
each treatment was replicated 3 replication. Major parameters was growth rate
and specific growth rate while minor parameters was temperature, dissolved
oxygen and pH. The result showed that treatment C which used Tubifex as feed
resulted the highest growth rate with 1.25 %/day and also the highest of
spesific growth rate was resulted from treatment C which used Tubifex as feed
with 1.39 %/day. This was caused that protein content in Tubifex was the
highest than in Artemia and Daphnia (63.05 %). Protein was the major nutrient
that affected fish growth performance. Protein supplied essential and non
essential acid amino that needed to muscle formation and enzimatic function,
beside that protein also had a role to energy availability preservation. The
result of water quality measurement showed that water quality was suitable for
snake head fry growth. Water quality toward that temperature between 20 oC - 27
oC, DO 3 - 4,50 mg/L and pH range from 5 to 8.42
