Natural Concurrent Infections with Black Spot Disease and Multiple Bacteriosis in Farmed Nile Tilapia in Central Kenya [PDF]
Veterinary Medicine International, 2020 Nile tilapia (Oreochromis niloticus) is the most cultured and available fish for Kenyan consumers, and therefore, any tilapine disease deprives them the valuable source of protein. Nile tilapia farm was diagnosed with severe concurrent black spot disease

Parasite Diversity in a Freshwater Ecosystem [PDF]
Microorganisms, 2023 Parasites are a significant component of biodiversity. They negatively affect fish appearance, growth, and reproduction. In this study, the prevalence of infection, diversity, and mean intensity of parasites were examined in 9 freshwater fish species (45

An expert-based risk ranking framework for assessing potential pathogens in the live baitfish trade. [PDF]
Transbound Emerg Dis, 2021 Abstract As global trade of live animals expands, there is increasing need to assess the risks of invasive organisms, including pathogens, that can accompany these translocations. The movement and release of live baitfish by recreational anglers has been identified as a particularly high‐risk pathway for the spread of aquatic diseases in the United ...

Temporally consistent species differences in parasite infection but no evidence for rapid parasite-mediated speciation in Lake Victoria cichlid fish. [PDF]
J Evol Biol, 2020 Species composition of Cichlidogyrus infection was similar among the closely related cichlid species of the Lake Victoria radiation (in orange), but differed between this lineage and two distantly related species (belonging to nonradiating sister lineages, in blue).

Improving tilapia biosecurity through a value chain approach
Reviews in Aquaculture, Volume 15, Issue S1, Page 57-91, February 2023., 2023 Abstract Tilapia aquaculture is a major source of animal protein, with global production reaching over 6 million tonnes in 2020. The rapid growth of the tilapia sector has led to a number of emerging disease threats and subsequent production losses. Risk analysis can provide a targeted approach for improving biosecurity in the tilapia sector.
