A 2016 study reported in the "Proceedings of the National Academy of Sciences" discovered that fish stocks are inversely proportional to water temperature. So as the water in the lake has been getting warmer, fish levels have been decreasing. We no longer know why things are heating up - scientists had a pretty good theory but ScoMo and other politicians have set them right about that.
Anglers going after Goliath tigerfish and Nile perch don't appear to have much effect on stocks; and nor do the traditional hook & line or gill net fishermen in their leaky canoes.
Clearly commercial fishing, which in the 1950's started using the infamous artisanal lift nets and industrial purse seines, has had a pretty big impact. There are about 800 fishery sites and around 100,000 people involved. But the industry collapsed in the 80's so I am not sure how many fishermen are actually making a living, especially as there are an increasing number of juvenile fish being caught. The catch in 1995 was around 196,570 tons. This fisherman has hooked a piece of Tanganyika rock, or maybe its a stonefish.
So here is the dilemma. Fish stocks declining as temperature rising. The only option is to reduce commercial fishing.
But these fish provide 60% of the animal protein consumed in the region. And children are turning up at school malnourished even now.
Go figure.Read more
