Overfishing - Coggle Diagram
Overfishing
Why is it a problem?
Too agresive fishing
Better technology = more overfishing
Too high rate of fishing
Just 10% of the pre-industrail population left
Fish is to cheap = wide selection
The use af massive nets(trawling)
Results in a lot of bycatch
And also a lot of debris on the bottom
Solutions
Fisheries managment
Better enforcement of laws
Global agreement
No more goverment subsidies
Catch limits
The farming of seafood
The start
startedin the early 1800s
Because of the oil for lamps in the blubber of whales
In the mid 1900s the whales were close to extinction
In the beginning of the 20th century the fishing started to accelerate
It accelerates so quick because it was a affordable protein-rich food
In the mid-20th century countries started to sent large profit-seeking fleets in to the sea
Consequences
Species can't reprodece them
Disruped balance in the sea
For example
Balance is of in the coral reefs
Not enough predator fish
To much predator fish
Ecosystems are out of balance
A collapse of the indrustry because of the lack of fish
Fishing deeper
Fishing deeper in the ocean because they are catching less and less
All the fisheries will collapse by 2048
