PENGARUH KONSENTRASI ALK(SO4)2 12H2O (ALUMINIUM POTASSIUM SULFAT) TERHADAP PERUBAHAN BUKAAN OPERKULUM DAN SEL JARINGAN INSANG IKAN NILA MERAH (Oreochromis niloticus)
Abstract: This research was
conducted since September until November 2008 at theWater Quality Management
and Paracyties and Desease of Fish LaboratoryFaculty of Fishery and Marine
Science Riau University. The aims of this researchwas to identify the damage of
gill tissue structure red tilapia (Oreochromisniloticus). This research using
experimental method and use completed randomdesign 1 factor with 4 treatments
and 3 replications. This research using red tilapiathe measure of 8-10 cm,
weight 30-40 gram from the hatchery in Pekanbaru.Result of the research show
the toxicant giving effect on gill structure changes ofred tillapia fish. Fish
of treatment experience of the change of structure of gillnetwork, especially
happened by the nekrosis, proliferasi cells, a few moltenlamella, haemorhage
and there are worm, and also secondary lamella.Concentration of toxicant hence
smaller footage and apart between secondarylamella of red tillapia fish. On the
contrary, excelsior of concentration of toxicant,hence wide progressively
secondary lamella of gill red tillapia fish. Result of theexperiments indicated
that toxicant of the AlK(SO4)212H2O concentrations havean effect on the gills
tissue structure of red tilapia. Concentrations of toxicantincrease caused the
gills tissue structure came to be better.
