Alaska pollock is the top fish catch in the world for four years running, toppling anchovies from Chile and Peru.

More than 40 million commercial fishermen were out at work on global waters on nearly five million boats, of which 90 percent are under 40 feet.

Those numbers have held steady over several years, says the latest State of World Fisheries and Aquaculture done every other year by the UN’s Food and Agriculture Organization. It is the only publication of its kind that oversees fisheries track records and trends around the globe.

Highlights from 2016 show that the world’s total marine catch was nearly 80 million tons, a slight decrease due to that drop in anchovies.

Aquaculture represented 53 percent of all seafood eaten and it is the fastest growing food production sector on the planet. Nearly 600 different species items are farmed around the world. The number one is carp.

Growing aquatic plants, especially seaweeds, has more than doubled in 20 years topping 30 million tons.

In per capita terms, global fish consumption has grown about 1.5 percent per year – from under 20 pounds in 1961 to 45 pounds last year.

Americans eat far less fish, averaging about 15 pounds a year.

So how are the world’s fish stocks doing?

Sixty percent were called ‘maximally sustained’ and 33 percent were classified as being fished at unsustainable levels.

Problem regions were the Mediterranean, Southeast Pacific and the Southwest Atlantic, with 60 percent of their stocks called overfished.

By contrast, the Northeast and Northwest Pacific and Central and Southwest Pacific had the lowest levels of overfishing ranging from 13 to 17 percent.

The World Fisheries Report said that impacts from climate change are likely to push down global ocean production by six percent by the year 2100 and 11 percent in tropical zones.
