The details
An upwelling phenomenon has recently caused the death of thousands of fish in Lake Victoria.
This natural occurrence has sparked concerns among fish farmers.
They suspect that increased levels of algae or pollution may have contributed to the upwelling.
Cage aquaculture in sub-Saharan Africa
Cage aquaculture, a rapidly growing food sector in sub-Saharan Africa, has seen a significant increase in popularity.
The number of cages has risen from just nine in 2006 to an impressive 20,000 by 2019.
The industry has experienced a threefold increase in size within East Africa alone between 2017 and 2021.
Yalelo Zambia, the largest tilapia producer in Sub-Saharan Africa, has adopted advanced technology to measure and mitigate farming disasters.
Their proactive approach includes using advanced techniques to predict and tackle the risks associated with upwelling.
Victory Farms, Kenya’s leading producer of caged fish, has also made significant strides in collecting data to address and mitigate upwelling risks.
Victory Farms has developed innovative technology to minimize losses during the transportation of live fish eggs.
This ensures the sustainability of their operations.
However, small-holder farmers face challenges in affording the necessary equipment to measure oxygen levels in cages.
They also lack knowledge about proper cage placement and feed quality.
AquaRech, a prominent player in the aquaculture industry, is currently developing a system to monitor water temperature in cages.
This technology aims to optimize feeding practices, leading to improved productivity and sustainability.
Environmental concerns
While the growth of cage aquaculture brings economic benefits, concerns regarding the environmental impact persist.
Accumulation of uneaten feed and fish waste beneath the cages raises questions about the ecosystem’s health.
To mitigate these concerns, Victory Farms conducts regular water condition tests.
They also operate within the lake’s natural carrying capacity.
The recent upwelling phenomenon in Lake Victoria has caused significant damage to fish farms.
The rapid growth of cage aquaculture in the region has provided opportunities for large-scale producers like Yalelo Zambia and Victory Farms.
These producers actively employ technology to tackle upwelling risks.
However, small-holder farmers face challenges in adopting such measures.
AquaRech’s efforts to optimize feeding through water temperature monitoring show promise.
Concerns regarding the environmental impact of fish waste accumulation beneath the cages persist.
Victory Farms ensures regular testing and adheres to the lake’s carrying capacity.
