Histological Changes In The Intestine, Muscle Of Brotia Costula (Gastropoda: Pachychilidae) Exposed Along The Langat River

Histological Changes In The Intestine, Muscle Of Brotia Costula (Gastropoda: Pachychilidae) Exposed Along The Langat River

Histological changes in the intestine, gills and feet of Brotia costula exposed to six stations along the Langat River were studied. Three other parameters such as susceptibility of the snail to river's water that was expressed in rLT 50 (relative Lethal Time 50%), water quality of the river...
