Abstract(s)

Gobio lozanoi, from the River Febros northern Portugal, contained female Philometra ovata in the body cavity causing abdominal swelling. A mild chronic inflammation and some tissue necrosis were observed in infected fish. Significant correlations were found between occurrence of infection and host length, and gonado-somatic index; and between intensity of infection and condition factor.
