Species-Specific Parasite Screening Kits for Tropical Aquaculture
A diagnostic testing kit designed for aquaculture farmers in Southeast Nigeria to detect high-prevalence parasites (specifically Neoechinorhynchus sp. 2) in Hepsetidae and Cichlidae fish populations.
Concept
A rapid diagnostic kit (e.g., a lateral flow assay or a targeted PCR panel) that allows fish farmers to screen for the most prevalent and high-intensity parasites identified in tropical freshwater lakes. Instead of a general health check, the kit focuses on the specific parasites that show the highest prevalence (up to 71.7%) and mean intensity, such as Neoechinorhynchus sp. 2, allowing farmers to treat specific stocks before a mass outbreak occurs.
Why now
Research shows that parasite prevalence in these freshwater ecosystems is high (overall prevalence of 59.5%), with specific species like Neoechinorhynchus sp. 2 causing significant worm burdens in certain fish families [0]. This high intensity of infection creates a commercial need for targeted screening to reduce fish mortality and improve yield in tropical aquaculture.

Who benefits
High parasite prevalence (59.5%) and high mean intensity in specific species directly threaten fish growth rates and survival, impacting profitability.
- Fisheries Department of Nigeriaorganization
Provides a tool for monitoring the health of natural freshwater lake populations to prevent the spread of parasites to commercial farms.
- Commercial Fish Farmerscompany
Reduces financial risk by identifying high-intensity parasite infections early in high-risk species, allowing for targeted treatment rather than broad-spectrum medication.
- Fisheries Regulatory Agenciesorganization
They can use standardized screening to monitor the health of natural lake populations and prevent the spread of parasites into commercial hatcheries.
- Tropical Aquaculture Farmerscompany
High parasite prevalence (nearly 60%) in natural waters increases the risk of infection in farmed stocks; targeted screening prevents mass crop loss.
- Tropical Aquaculture Farmersindividual
They suffer financial losses from high parasite prevalence in freshwater stocks and need a way to identify specific high-burden infections to apply targeted treatments.
