| Abstract: | The life cycle and annual production of four dominant species of Chironomids (Chironomus plumosus, Chironomus sp.,Clinotanypus sp.,Tokunagayusurika akamusi) were studied with samples taken monthly in Biandantang Lake at eight stations from April, 1996 to March, 1997. Instarfrequency
data showedC. plumosus was univoltine, while the other three were bivoltine. Production in wet weight (g/(m2·a)) calculated by the size-frequency method for each species were:C. plumosus, 2.663;Chironomus sp., 1.161;Clinotanypus sp., 0.270;T. akamusi, 1.476. Based on the mean standing stock, their P/B ratios were 3.2, 4.0, 6.2, and 4.4, respectively.
