Which sea has no fish?
The sea is called “dead” because its high salinity prevents macroscopic aquatic organisms, such as fish and aquatic plants, from living in it, though minuscule quantities of bacteria and microbial fungi are present In times of flood, the salt content of the Dead Sea can drop from its usual 35% to 30% or lower

Why is commercial fishing bad?
Aside from deliberately catching vast numbers of fish and engaging in practices like trawling which cause damage to ocean habitats, commercial fishing accounts for vast quantities of bycatch – where non-target species of marine animals are accidentally (or sometimes intentionally) caught, then tossed dead or dying back Sep 28, 2020
Will there be no fish in 2050?

How did the Dead Sea get so salty?
