Blog Tags: Ocean Infographics
This is part of a series of ocean infographics by artist Don Foley. These infographics also appear in Oceana board member Ted Danson’s book, “Oceana: Our Endangered Oceans and What We Can Do to Save Them.”
Have you ever asked yourself, “Where does my seafood come from?” It's not as easy to figure out as you might think. Eighty-four percent of seafood eaten in the U.S. is imported, and it follows an increasingly complex path from the fishing boat to our plates, as today’s infographic illustrates:
Here are the steps your fish may take before it gets to you:
Step 1: All of the seafood sold in the U.S. is either caught by fishing vessels or raised in aquaculture facilities. Fish and shellfish are put on ice or flash-frozen on board the vessel or at the aquaculture facility.
This is the second in a series of ocean infographics by artist Don Foley. These infographics also appear in Oceana board member Ted Danson’s book, “Oceana: Our Endangered Oceans and What We Can Do to Save Them.”
With shark week fast approaching, how about a shark-related infographic to whet your appetite?
Today’s infographic illustrates how overfishing fundamentally alters ocean ecosystems, leading to fewer and smaller fish over time.
If overfishing isn’t stopped, the largest fish like sharks, tuna, cod, and salmon eventually run out and overfishing expands to previously untargeted, smaller species, some of which were considered undesirable. As a result, the world catch is now primarily made up of small fish like pollock rather than large predators like grouper, and this shift to smaller and smaller species over time is called “fishing down the food chain.”
Since a lot of what happens in the oceans is hidden from view, the issues we discuss here on the blog can often be abstract and hard to visualize.
That’s why starting today, I’ll be featuring an ocean infographic by artist Don Foley each week. These infographics also appear in Oceana board member Ted Danson’s book, “Oceana: Our Endangered Oceans and What We Can Do to Save Them.”
I thought I’d start with one of the most mysterious players in the ocean: fishing gear. I don’t know about you, but I’ve never actually seen any of these in real life (have you?), so I find this infographic quite helpful:
Dredges catch scallops and fish by dragging across the seafloor. They can crush corals, catch sea turtles, and disturb all kinds of seafloor life.
Purse seine nets catch schooling fish like tuna by encircling the school with a wall of netting. They can capture dolphins and other natural predators feeding on the school.
Trawl nets catch shrimp, cod, haddock, and other fish. Bottom trawls drag weighted nets across the seafloor, crushing corals or any other marine life in their path. Bottom trawls also discard more unwanted fish than almost any other form of fishing and are extremely destructive. Midwater trawls drag large nets through the water to catch pollock and other schooling fish, and when their nets are full, they may also drag on the bottom.
Gillnets are one of the most widely used methods in the world for catching salmon and sharks. When not closely tended, gillnets can entangle and drown sea turtles, seabirds, and marine mammals. Some gillnets also snag large numbers of juvenile fish, which contributes to overfishing.
