The composition, density and distribution of the zooplankton in Parakrama Samudral 1980. Twenty-four samples from six sites and on four occasions revealed the presence of a zooplankton consisting of rotifers and protozoans, mainly ciliates, and the virtual absence of crustacean zooplankton (apart from . and . in a . bed). Compared with a previous visit in August and September 19

A diurnal study of the planktonic rotifer populations in Parakrama Samudra Reservoir, Sri Lankas were present, of which ten were carrying eggs. Counts revealed changes in the percentage composition of rotifer species as well as in their distribution with depth throughout the day. The abundance of rotifers ranged from 3.78 X 10.lnd m.to 10.04 X 10. lnd m., with the lowest values occurring duri

The influence of temperature upon the duration of embryonic development of tropical , species (Rotif and compared with data on . from a neighbouring water body. The duration-temperature regressions differed in elevation, but not in slope for 28 °C. They predict a duration of embryonic development of 5.67 h for B. . and 10.51 h for.. The difference lay not in their responses to temperature, since t

Feeding studies with natural food particles on tropical species of planktonic rotiferstes of . from Parakrama Samudra and .from the Milk Factory Tank were measured on natural food particles of less than 33 µm, using a radio-tracer technique. The concentration of food was determined as carbon per millilitre. At 28 °C, the hourly filtering rates for B..ranged from 1.63 to 6.10 µlind.h.

Sediment characteristics and benthic community oxygen uptake rates of Parakrama Samudra, an ancient oxygen uptake rates of undisturbed sediment cores and oxygen consumption rates of the lake water were measured. The results provide evidence that most of the primarily produced organic matter is mineralized in the pelagic zone. Decomposition processes are distinctly higher in the pelagic zone compa

Aspects of gut passage of algal cells in , (Peters), (Pisces, cichlide)of digestion of the cells and filaments taken from different parts of the intestine is assessed by measuring pigment degradation. Experimental evidence for the viability of the algal material from the hind gut is demonstrated by photosynthethic oxygen evolution. Quantification of the relative abunda
