Why are fish kills and antimicrobial resistance rising in Kenya?
In Kenya, water quality issues such as pollution, algal blooms, and overuse of antibiotics in aquaculture are causing increased fish kills. These conditions also promote antimicrobial resistance, making disease management more difficult and threatening the sustainability of local fish industries.
-
Can invasive species be turned into economic opportunities?
Yes, some regions are exploring ways to turn invasive species into economic benefits. For example, promoting angler tourism or dried fish products from invasive fish like the snakehead can create new income streams, but this requires careful management to prevent further ecological damage.
