Results and Discussion Table 2 lists the parasites identified, where they were located in or on the fish and in what quantities they were recovered. A total of 12 species of parasites were recovered from the three sunfish. Four species of parasitic copepods were found, two of which caused lesions on the body surface of the fishes, namely Orthagoriscola wilsoni (Schuurm-Stekhoven, 1956) and Philor- thagorisciis serratiis (Kro

Results and Discussion Table 2 lists the parasites identified, where they were located in or on the fish and in what quantities they were recovered. A total of 12 species of parasites were recovered from the three sunfish. Four species of parasitic copepods were found, two of which caused lesions on the body surface of the fishes, namely Orthagoriscola wilsoni (Schuurm-Stekhoven, 1956) and Philor- thagorisciis serratiis (Kroyer, 1863). P. serratus was found lying in small lesions mm in diameter in the tail region of fish No. 3. In many cases all of the copepod visible was the long t^^ strings of the female. In all three sunfish examined a lesion was found behind the anal fin; in the case of specimen No. 3 the lesion was 105 x 45 mm in diameter, and contained a number of specimens of P. serratus lying deeply embedded in the subcutaneous tissues. Five species of trematodes were found, including Capsala martmierei Bosc 1811, an ectoparasite which was generally found in greatest numbers in the region of the pectoral fin. When a specimen of this helminth was removed from the body surface of the fish the area of skin lying directly below the.
