“…This observation lends support to the view that this conchostracan is a non-selective feeder. This is in accordance with the findings on Artemia salina (Reeve, 1963, 966), S. dichotomus (Bernice, 1970) and on chironomid larvae (Alfred, 1974). Zooplankters such as cladocerans, copepods and ostacods were totally absent in the gut although these were present in the environment.…”

“…Zooplankters such as cladocerans, copepods and ostacods were totally absent in the gut although these were present in the environment. Similar situations were recorded in S. dichotomus (Bernice,197I ) and in chironomid larvae (Alfred, 1974). This probably be so because zooplankters are larger and mobile and hence they cannot be easily wafted into the gut by the feeding currents of these organisms.…”

Studies on the food and feeding habits of Leptestheriella maduraiensis Nayar & Nair have shown that the organisms are nonselective algal and detrital filter feeders. They utilise available food in almost similar proportions as in the overlying pond water and it is found from the present studies that the phytoplankton (Bacillariophyceae, Chlorophyceae and Cyanophyceae) form the major part of the gut (48.9%), followed by detritus (38.6°%), zooplankton ( . %) and miscellaneous items ( .4%).

Absorption efficiencies of nitrogen and carbon in twoChironomus species found dominating in the profundal zone of mesotrophic Lake Erken were determined gravimetrically.2. Absorption efficiencies for C. plumosus showed greater seasonal variation than those of C. anthracinus, with low efficiencies coinciding with the summer dominance of flagellate phytoplankton and with high C:N ratios.3. Overall mean absorption efficiencies {±SE) for carbon and nitrogen, respectively, were 26.8% (±1.9) and 29.3% (±1.9) for C plumosus, 24.6% (±1.7) and 28.1% (±1.8) for C anthracinus.4. Significant differences were found to exist between the C:N ratios of the superficial 2 cm sediment layers and those of Chironomus anterior midgut contents. 5. C. anthracinus appears to be a deposit feeder ingesting particulate matter scraped from the recently deposited surface sediments. The greater seasonal variation found in the absorption efficiencies of C. plumosus, together with the lower C:N ratios, support the contention that this species is a filter feeder with the nutritional quality of ingested matter depending primarily on pelagic inputs.

A broad categorisation of Indian freshwater investigations published so far is presented. The lacunae are pointed out. Problems and priorities for further limnological researches in the context of India's limited water resources are high-lighted.Studies on Indian freshwaters extend back to the latter half of last century and were in the nature of presenting species lists and descriptions of taxa new to the then Indian sub-continent (Carter
