“Thousands of livelihoods were destroyed” after scores of fish died in Kenya’s Lake Victoria

Kenyan fish cage farmers in Lake Victoria have suffered big losses after their fish shares died in early November, which specialists have attributed to upwelling and air pollution. Footage circulating on-line and despatched to us by our observers present hundreds of lifeless fish in cages in Lake Victoria. Greater than 364 million fish are believed to have died, with an estimated worth of 1.4 billion Kenyan shillings (equal to 11 million euros).

Our observer, Ian Omondi Otieno, is a fisherman in Kisumu, a city bordering Lake Victoria. He stated he had been saving to purchase a fish cage for 5 years and at last purchased one for 370,000 Kenyan shillings (€3,000) earlier this yr. He had hoped to make some revenue. However all he has now are useless shares which have set him again the equal of hundreds of euros.

“Fishing is the backbone of our economy”

Originally of November I went out to the lake and located numerous fish floating on the floor, useless. Others had washed up on the seashores. It’s a tragedy. Thousands of fish have died, and that is simply on our facet of the lake. For different communities round Lake Victoria, it has been even worse.

The scenario is inflicting huge stress, hundreds of livelihoods have been destroyed. I noticed a fisherman crying uncontrollably after discovering the lack of all of the fish in his cage. He tried to commit suicide.

Fishing is the primary supply of revenue in my city. Round 90 p.c of our inhabitants relies on fish, it’s the spine of our financial system.

In an effort to scale back losses, the fishermen are actually harvesting the useless fish to promote as a daily number of dried fish. On November 13, the Kenya Marine Fisheries Analysis Institute (KMFRI) warned fish farmers to test for indicators of contamination earlier than consumption.

Specialists at KMFRI stated the fish died resulting from upwelling, a pure phenomenon involving temperature adjustments and lack of oxygen. Regurgitation often takes about an hour, however in the course of the course of caged fish are sometimes disadvantaged of oxygen.

It’s assumed that international warming amplifies the temperature gradients between land and sea which in flip improve favorable winds for upwelling. Local weather change has been strongly felt in Africa’s largest lake, which might due to this fact clarify the rise in upwelling developments.

Evaporation, lack of rainfall and adjustments within the tilt of the earth’s axis imply that the lake is now prone to disappearing. A 2020 research analyzed historic and geological information from the previous 100,000 years and located that the whole physique of water might disappear within the subsequent 500 years.

Lake Victoria receives most of its water from rain (about 55 inches every year). However in response to a research by the Nationwide Science Basis, rainfall ranges 35,000 to 100,000 years in the past had been about 28 inches, or almost half of what they’re at present. Low rainfall has prompted the lake to dry up at the least thrice within the final 100,000 years, and it might occur once more.

The KMFRI group additionally blamed heavy air pollution and discharge of uncooked sewage into Lake Victoria, which has prompted algae and the wild water hyacinth to develop.

“Industries have treated the lake like a garbage can”

Ian Omondi Otieno additionally believes air pollution is in charge.

Lake Victoria was once clear and a spot the place marine life thrived. However in recent times it has modified rather a lot. It has turned brown or inexperienced and it smells actually dangerous. It used to style clear, however I do not even wish to attempt consuming it anymore. This yr the scenario is worse than ever.

Scores of industries, together with numerous resorts, are constructed across the lake. They’ve thrown plastic and different poisonous waste into the water. They’ve handled it like a rubbish can. So the fish have eaten this air pollution, it has killed them.

The communities round Lake Victoria, the world’s second largest lake, have relied on the water physique for meals, vitality and water for generations. In response to the World Financial institution, the lake helps over 40 million residents, almost 50 p.c of them on lower than $1.25/day. Lake Victoria has additionally traditionally been a supply of essential biodiversity and residential to tons of of fish species.

However in recent times scientists have warned that Lake Victoria is ‘dying’. They’ve blamed overfishing and air pollution for severely broken fish shares.
