Infection of Sphyrion laevigatum (Copepoda: Sphyriidae) on Genypterus blacodes (Pisces: Ophidiidae) from the Falkland Islands, South Atlantic.
The degree of parasitism by the parasitic copepod Sphyrion laevigatum on kingclip Genypterus blacodes in the Falkland Islands was investigated. In a sample of 719 kingclip, ranging in size from 35 to 145 cm total length, the prevalence of infection was 49%. The number of parasites per fish ranged from 0 to 24, with only 2% of the sample having more than 5 parasites. There was a significant increase in mean abundance of parasites with increasing fish age and length (P < 0.01 and P < 0.05, respectively). In addition, there was a significant difference in the prevalence in 1 of 3 geographical areas for the largest size class.
