Over-fishing

The pros, cons, and other information about how over-fishing

affects the world.

Summary

• Without fish, the whole world could dramatically change

• Fishermen should care because their jobs are on the line

• A lot of other people should care because they eat the fish

• Species like the blue fin tuna and some sharks are disappearing

The Pros and Cons

• Pros– When all of the fish is sold to a market or any

store, people can ingest vital nutrients.

• Cons– Without a lot of fish, larger fish can go hungry

and that can ruin the food chain.– When there is a small number of fish,

fishermen lose jobs.– After the fish are hauled on a boat, the fish

have trouble replenishing their numbers.

How The Fish are Used

• People eat the fish after they are sold to a store or market (36 million tons a year).

• Natural predators also eat the fish.

Who is Affected?

• The North Sea, Canada’s East Coast, and the U.S. are experiencing low amounts of fish.

• Some communities that depend on fishing to meet their needs.

Our Opinions

• We should stop our relentless fishing.• We should also look to a more abundant species

of fish as an alternative.

• These fish have populations of over 1 million individual fish.

• However, we should fish these alternative species carefully.

Solutions and Feelings About Them

• Find a booming population of fish like the veiled anglemouth (showed last slide).

• Fishermen will regain jobs.• People will have a new exotic fish to eat.• But, we should fish these abundant species in

small pockets, only fishing when absolutely needed.

• Fishermen wouldn't like this because they probably won’t get paid as much (the usual 80 billion a year).

• People will most likely have and increasing demand for the new fish.

Other Information and Facts• The blue fin tuna, an over-fished species, could become

extinct in a few years.• Japanese fishermen catch the blue fin more than any other

country.• Many species of shark are also being over-fished.• When sharks disappear, so do scallops.

• There aren’t enough sharks to eat rays and skates that eat the scallops.

• Then, when the rays dig up the clams, shrimp and other shellfish’s eggs are destroyed.

• All because we over-fished sharks.
