| Abstract |
Young estuarine bass of the 1976 and 1977 year classes were examined for gill parasites between February 1978 and June 1979. 344 specimens of the copepod Lernanthropus kroyeri were recovered from 177 of 289 fish. The distribution of the copepods on the gills showed clear preferences for site of attachment. With 48 such sitesdelineated per fish, 143 of 183 female copepods favoured a single site--the internal face of the medial sector of the posterior hemibranch of the second gill arch. Explanations for the observed distribution are discussed in terms of the strength of the branchial ventilation currents over the different gills coupled with observations on the special respiratory adaptations of these parasites. |
