Billions of fish migrate southward to the Mekong River in Cambodia each year. This migration attracts fishermen, who take advantage of the abundant harvest. The river is so full that one fishing net can pull in up to 600 pounds of fish. Few studies have been done to track the migrating fish to measure the health of their population. So National Geographic Explorer Zeb Hogan has joined a fishing crew along the Tonle Sap River, which connects the largest lake in Southeast Asia to the Mekong River, to tag fish and determine how many survive the journey. While massive numbers of fish are on the move during the migration season, overfishing and dam building have taken a heavy toll on fish numbers.

  • 9385dee7 on April 3, 2017

    who the hell ever thinks that hauling 600 pounds of fish out the water in a single netting is a good idea?! how is that ever going to be sustainable? seriously, use your head.

    Killing innocent animals. Why are these people not in jail??

  • jtiss _ on April 3, 2017

    Hopefully in the future, land based fish farms will become the norm so we dont have to over fish the oceans.

  • Lara Dajani on April 3, 2017

    which river?

  • Fruitarian on April 3, 2017

    that tag already killed the fish

  • Collin Bryan on April 3, 2017

    Maybe spend less time on glamor shots of the fish as they go extinct too
    Also you didn't have anything about science

  • Error 404 on April 3, 2017

    it's a sea of fish 😅

  • nesseiht gnay on April 3, 2017

    as long as they dont kill off the fishes and make every fish go extinct too

  • Ruben Scott on April 3, 2017

    And there is no more fish in a few years they will change there migration and so will the fisher men

  • LeesaDeAndrea on April 3, 2017

    Just like all the conservation stories everywhere: nothing but disaster caused by humans.

  • H4WK69 on April 3, 2017

    As long as its sustainable its acceptable imo

  • The Mopomi on April 3, 2017

    I can't wait for the moment where these fishermen to die because there will be no more fish in the future cause large ships already caught them all

  • Vegan Tony on April 3, 2017

    GO VEGAN

  • LATIN THRONE ENT on April 3, 2017

    Who else is baked

  • Juan Moar on April 3, 2017

    That's my country and it's a disgrace to see them overfishing/overhunting everything they can find.

  • rdizzy1 on April 3, 2017

    The only way people will learn to not over fish an area is the hard way, when they go to fish 10 years later and catch little to nothing and end up starving as a result.

  • C B on April 3, 2017

    The fish are migrating, to feed and breed. The humans catch and kill them all before they get to. Not only are they killing all these fish, but their future generations too that never got the chance to be born. The big fish, just because of their size are a target. Instead of being amazed by the chance they had to get that big, the humans see them as trophies to kill instead of letting them keep growing. If aliens/or whatever killed the tallest humans for their size and killed every other human in the thousands or millions…will that make the humans finally understand their selfish, greedy, ruthless, murdering, polluting, destroying, extinction causing ways?

  • Ilham Arifin on April 3, 2017

    meanwhile in another paralel world, fish selling humans. and debated how can fish can kill inocent human population like that?.

  • Trey Sahlberg on April 3, 2017

    Looks like people will be on the protein menu soon since nothing is left.

  • Reklesnes on April 4, 2017

    all i saw was over fishing and thats good for science? makes sense to me

  • wp me antroo on April 4, 2017

    [*]

  • Adam Rounds on April 4, 2017

    Kinda could have put down the reason!?

  • dojo on April 4, 2017

    As long as sea life has to come up for air, they don't stand a chance. Fucked!

  • Recommended on April 4, 2017

    these morons clearly don't think about the future.

  • Steve Lee on April 6, 2017

    At least when the fish are gone, they can scrape the bottom for clams and bottom feeders until those get wiped out too.

  • Joon - young on February 27, 2018

    things humans will do for meat. sigh 😔

  • Mark Frost on June 13, 2018

    How many fish do they do they need to feed the village just way to many they don't need that many fish they fishing for what they can get out of it, money

  • Cam C on February 7, 2019

    I was hoping the fish were consciously luring the fishermen to their deaths or something..

  • Sam Sardar on November 15, 2019

    This is blessing

  • Beep on January 8, 2020

    A lot of people in the comments are saying this is overfishing, I'm pretty sure the fish caught here are small asian carp. Which when spawning can produce 1 million eggs every year (if not multiple times a year)

  • MISFIT on November 30, 2021

    We just get what we need and release the rest. That's how we fish.
