Abstract
The fecundity of Clupisoma naziri was studied by gravimetric method. Ovaries were weighed to the nearest mg. Then a part (75-100mg) was cut from their mid points, weighed and processed for separating and counting the eggs. Absolute fecundity varied from 1403 to 17255 eggs for a fish of 21.5cm to 32.2cm total length and 55gm to 278gm body
weight. The relative fecundity varied considerably. Relation of fecundity
to size revealed that the larger fish were more fecund than the smaller
ones. Egg diameter was measured with the help of a calibrated ocular
fitted electric microscope at 40X magnification. The diameter ranged
from 1215µm to 1509µm. Further up and low stream data may identify
best spawning locations of the fish.
