A global review of problematic and pathogenic parasites of farmed tilapia

Reviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Development of cod farming in Norway: Past and current biological and market status and future prospects and directions

Reviews in Aquaculture, Volume 14, Issue 1, Page 308-342, January 2022., 2022
Abstract Atlantic cod is a historically abundant species in the North Atlantic region and has contributed to the prosperity of many nations. But a decline in stocks in the last century has prompted to initiate commercial farming of cod in captive conditions.

Mortality in Atlantic Salmon (Salmo salar) Associated with Trichodinid Ciliates [PDF]

Journal of Wildlife Diseases, 1991
A protozoan infection (Trichodina truttae) was identified in captive Atlantic salmon (Salmo salar) kelts that died in spring of 1988 and 1989. Fish with intense infections showed signs of listlessness, erratic swimming and inappetence. The infection induced excessive mucus secretion, epithelial sloughing and lesions that probably permitted entry of ...

Observations on Tripartiella bursiformis, Trichodina nigra and a Pathogenic Trichodinid, Trichodina fultoni [PDF]

Bulletin of the Wildlife Disease Association, 1967
A series of epizootics caused by Trichodina fultoni is reported. Fish kept in running water at 12°c showed severe signs of trichodiniasis. At 12 °C T. fultoni lacked strict host specificity, but demonstrated some preference. A redescription of Tripartiella burstjormis, using the silver impregnated techniques, is given.

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

Asian Fisheries Science, 1989
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.
