DISTRIBUSI KEPITING BAKAU Scylla serrata BERDASARKAN KETERSEDIAAN PAKAN ALAMI DI EKOSISTEM MANGROVE BELAWAN SUMATERA UTARA
ABSTRACT: Mud crab Scylla
serrata can be found almost in all Indonesian water especially in mangrove
ecosystem ranging from river mouth, coastal water, to open sea depends on their
life stages. The research has been done within 7 months from April to Oktober
2012 in Belawan mangrove ecosystem North Sumatera. This research aims todetermine
the distribution of mangrove crabs by size class associated with the
availability of natural feed. Natural food availability characteristics based
on macrozoobenthos abundance at each station were analyzed using Principal
Component Analysis Habitat characteristic of mud crab in each station as
analyzed using Principal Component Analysis. Distribution of mangrove crabs
associated with natural food availability were analyzed using correspondence analysis.
Research results show that mangrove crab males and small females are found at
the station with the availability of natural feed macrozoobenthos genus Thais,
Pila, Barbatia, Perisretnia and Telescopium; Large female crabs at the station
with natural feed genus Cerithidea, Atrina, Nereis, Terebralia, Certhium,
Nerita, Pinna and Pleuroploca; Male and female crabs medium-sized, large-sized
male crabs, are found at stations that have natural food availability genus.
Littorina, Pinna and Pleuroploca.
