Trichodinids (Protozoa: Ciliophora: Peritrichida) of Nile Tilapia (Oreochromis niloticus) in the Philippines

Abstract

During a survey of the trichodinida of wild and cultured Nile tilapia (Oreochromis niloticus) throughout the Philippines, a total of eight species belonging to two genera were encountered. Among these was Trichodina r,elasquezae n. sp., from the skin and gills of brackishwater cultured tilapia from Leganes, Iloilo. Other species identified include T. centrostrigata Basson, Van As, and Paperna, 1983; T. acuta Lom, 1970; T. heterodentata Duncan, 1977; T. siluri Lom, 1970; Trichodina Bp.; Tripartiella clavodonta Basson and Van As, 1987; and Tripartiella tilapiae (Duncan, 1977) n. comb. Trichodina equatoralis Kazubski, 1986 is considered a synonym of T. heterodentata, while Trichodinella lechridens Basson and Van As, 1987 and T. macrosoma Basson and Van As, 1987 are regarded as synonyms of Tripartiella tilapiae.
