Peradeniya, 1998) Wijesinghe, M.R.; Jayatunga, Y.N.A.; Hewamanne, R.The nature of the relationship between bioaccumulation of heavy metals and body size (length) in Oreochromis mossambicus from Beira Lake and Weras Ganga in the Colombo District of Sri Lanka was inverstigated. The work was carried out during March - July 1995. The organs; muscle, gills, gonad, kidney and liver were investigated. Analysis was done by the x-ray fluorescence method. There was a significant difference (p0.05) in the metal levels in a paricular organ between the different length classes. A positive ans statistically significant correlation with body length was seen for Cu concentration in the kidney in both the Beira Lake and Weras Ganga samples. A significant positive correlation with body length was observed for Zn in the gill and kidney, and for Fe in the muscle and liver, of the Beria LAke sample. For Cd in the muscle, a significant negative correlation with length was observed in the Beria Lake sample. This is noteworthy since the muscle is the tissue that is normally consumed. In the same site there was also accumulation of lead in one of the smaller size classes.Item Importance of ectoparasitic ciliate infestations in the farming of snakehead fishes (Channa spp.) (Teleostei:Channidae) in Sri Lanka(Univer, 1986-87) De Silva, K.H.G.M.Item Food and feeding biology of the endemic carplets Barbus cumingi and B.nigrofasciatus (Oateichthyes, Cyprinidae) of Sri Lanka(1994) De Silva, K.H.G.M.; Somarathne, R.M.D.The food and feeding biology of B. cumingi and B. nigrofasciatus were studied in a small stream of the upper reaches of the river Mahaweli. Both species are herbivorous substratus feeders and their diets consist mainly of diatoms and detritus. Diatoms were the most abundant food item (50.1perc.) in the diet of B. nigrofasciatus but both diatoms (36.8perc.) and detritus (38.4perc.) were common in the diet of B. cumingi. Both species appear to avoid blue-green algea. The relative abundance of detritus and diatoms in the diet of both species varied from month to month and the importance of diatoms generally increase and that of detritus decreased with the increase of body size. The "intestinal" contents of B. cumingi contained a larger amount of diatoms in comparison to that of "stomach" contents, whereas in B. nigrofasciatus the amount of diatoms was low in the intestine. The relative gut length(RGL) of B. cumingi varied from 0.96 to 2.64 while that of B. nigrofasciatus varied from 0.89 to 2.54. These ranges agree well with reported RGL ranges for other herbivorous cyprinids. The RGL increased with increase in body size in both species as has been observed in other cyprinids.
