PENGARUH PERBEDAAN SUMBER AIR DAN JENIS PAKAN TERHADAP PERTUMBUHAN DAN KELANGSUNGAN HIDUP KEPITING BAKAU (Scylla serrata) PADA TAMBAK DESA MOJO
Abstract: This study aims to
examine and analyze the growth and survival of mud crab (Scylla serrata) with
different water sources and different types of feed. This study used a design
Plots Divided (Split Plot Design), with the main plot of water resources (soil
and brackish water and brackish water of the channel) and the subplot kind of
feed (trash fish, squid, crab wideng) with replications for three (3) times .
Feeding twice a day ie morning (at 06.00) and afternoon (17:00 hours) at a dose
of 15% of the feed weight. The study was conducted from November to December
2013. Biota initial weight ± 100 g. Parameters measured were the growth of the
absolute weight of mud crab (Scylla serrata) and survival rates. The results
showed growth in the absolute weight of mud crab (Scylla serrata) week 1 to
week 4, there is a tendency to rise and survival rate evenly among all
treatments. The growth of the absolute weight of mud crab (Scylla serrata) the
best of the week 1 to week 4 are the treatment of brackish ground water sources
and feeding trash fish. At week 4, which is the end of the study the highest absolute
growth of 57.7600 g ± 5:44 (brackish ground water and trash fish) and the
lowest was 35.0000 ± 1.80 g (brackish ground water and crab wideng). As for the
survival rate of mud crab (Scylla serrata) at 96.3% on a weekly basis.
