Swar D, Fernando C (1979) Cladocera
from Pokhara Valley, Nepal with notes on distribution.
Bythotrephes cederstroemi (Schodler) (Cereopagidae, Cladocera
)--a new record for Lake Ontario.
Subsamples measuring 10.5 mL for Ostracoda, 0.2-1.5 mL for chydorid Cladocera
, and 2.0-3.0 mL for Chironomidae were prepared by dispersing the sediment matrix in warm 10% KOH for 45 mm (Walker and Paterson 1985), and sieving through 250-[micro]m and 105-[micro]m mesh sieves.
A total of 76 zooplankton species were identified in the lake, including 17 protozoa species, 36 rotifera species, 12 cladocera
species and 11 copepods species, respectively.

The water flea Daphnia magna (Crustacea, Cladocera
) as a test species for screening and evaluation of chemicals with endocrine disrupting effects on crustaceans.
The effect of air temperature on species richness was analyzed for each zooplankton group individually (Copepoda, Cladocera
and Rotifera) and also for total zooplankton.

Differences in species present between the two studies occur primarily in the Cladocera
(18 species in this study compared to eight species in previous study) and the Rotifera (38 species this study compared to 10 species in the previous study).
Other occurring taxa included Cnidaria, Cladocera
, Ostracoda, Amphipoda, Mysidacea, Pteropoda, Larvacea, and Chaetognatha were represented by a small number of species (Table IV), contributed collectively 19.68% and about 1% of the species richness and total abundance, respectively.
