PENAMBAHAN TEPUNG RUMPUT LAUT Kappaphycus alvarezii DALAM PAKAN KOMERSIAL TERHADAP PERFORMAN IKAN NILA (Oreochromis niloticus)
ABSTRACT: Tilapia (Oreochromis
niloticus) is one of fish that is suitable to be cultivated in floating net cages
or in controlled containers, since tilapia is the omnivorous and is easily
adjust to theenvironment. An artificial feeding in an intensive farming is one
of the importantsupporting factor to increase production. Natural feed
available could not meet the needsof fish, therefore in order to promote
growth, it must be fulfilled by the artificial feed thatcould qualify
nutrition. The research aims to observing the dose addition of flourKappaphycus
alvarezii in commercial feed to enhance the growth and the survival of O. niloticus.
The usability of the research is the costs efficiency of feed and providesinformation
on aspects of tilapia fish farming. The result of the research shows that dailyspecific
growth rate performs that control treatment (0.94±0.14%) gives the best growthresponse
compared to the treatment of seaweed flour 20% (0.06±0.04%), then is followedby
the treatment of seaweed flour 5% (0.52±0.17). Further research statistic
peforms that the control is significantly different to the treatment of seaweed
flour 20% (p<0.05). Forthe best feed convertion ratio is in control
(0.31±0.02) and the lowest is in the treatment ofseaweed flour 20% (0.45±0.03).
Then the best survival is in control treatment(80.00±0.00%), followed by
treatment of seaweed flour 5% (76.670±0.00%) and the lowest survival is in
treatment of seaweed flour 20% (63.33±0.06%).
