Abstract
Background
This review was conducted from 1996 to 2020 aiming to compile the findings of parasites of freshwater fishes of Sudan in a single document.
Methods
The present review was based on 105 scientific paper, 3 conferences abstracts, 3 graduation dissertation, 7 master and 2 Ph.D. theses, one unpublished reports, 10 books, and one technical report. The work covered the period from 1902 to 2020.
Results
Some thousands of freshwater fish specimens were examined for their ecto-parasites and/or endo-parasites. Fifty-eight fish species were reported infected and 162 parasitic species including 32 new species were collected. The parasites found were three bacterial and three fungal species collected from Oreochromis niloticus. From 10 species of fish, 19 protozoans were described. From 10 species of fish, 22 Monogenean species were found including 7 new species. One new Aspidogastrean species was collected from Labeobarbus bynni. From 29 fish species 23 Digenean species were collected including five new ones. From 41 species of fish, 44 species of cestodes parasites were collected including 11 species new to science. Twenty parasitic Nematodes species including seven new ones were collected from 32 fish species. From 12 fish species 9 Crustacean were described. Nine Acanthocephalans including one new species from Ichthyborus besse were collected from 11 fish species. Co-infection was observed.
Conclusions:
The collected parasites included 31 new species to science. One new subfamily Sandonellinae from Heterotis niloticus was erected; and 10 new genera, Brevicaecum, Sandonia, Afromacroderoides (Digenea); Wenyonia, Sandonella, Amirthalingamia, Barsonella lafoni (Cestoda) and Dichelyne, Nilonema, (Nematoda) were described. Revision of parasitic species designated as CithariniellaTrypanosoma type 1, 2, 3; Dactylogyrus species type 1, 2, 3, 4, 5; Dogielius sp. 1;Amplicaecum type 1 and Amplicaecum type 2; Contracaecum sp. Third stage-larvae Type 2; Procamallanustype 1, 2, 3 and those parasites identified to the genus level should be given due attention. Some recommendations for further research were offered
