Over fishing = taking more fish than nature can replace.
Fish stock = the available supply of fish.
Cause of over fishing
Modern fishing methods and technology means that it is easier to catch more fish.
The world’s population has doubled in the last 50 years. Fishing companies must take more fish to feed the population.
There are not enough international fishing laws to stop people from over fishing.
Effects of over fishing
It reduces the amount of food
It effects many other plants and animals in the sea.
The reduction in fish supply leads to unemployment and poverty.
Quota = a maximum amount of fish allowed.
Habitats = it is a place where specific plant or animal lives.
Size restrictions = it limits the catching of fish and lobsters which are too small to breed.
Laws and quotas
Quotas are set so that companies and people cant over fish a certain fish. When the quota is reached no more fishing is allowed.
Size restriction laws are helping to reduce overfishing.
Marine protected areas.
The main aims of marine protected areas are..
To provide a safe place for fish stocks to breed and grow
To protect important habitats
ragging a large net or cage along the seabed. (it damages the marine habitats)
companies use large nets to catch fish. These nets catch a lot of young fish and this is bad for the breeding of the species.
Educating people about overfishing can help them to become involved in saving fish.
