Cli­mate Change Pushes Fish Across Bor­ders, Po­ten­tially Caus­ing “Fish Fights”

Asian Diver (English) - - What Bubbled -

In re­sponse to warm­ing waters, the fish in our oceans are mov­ing out of na­tional bound­aries and dis­rupt­ing the world’s sys­tem for al­lo­cat­ing fish stocks. This could po­ten­tially lead to in­ter­na­tional dis­putes.

“Marine fishes do not have pass­ports and are not aware of po­lit­i­cal bound­aries; they will fol­low their fu­ture op­ti­mal habi­tat,” says Gabriel Rey­gondeau, co-au­thor of the study and post­doc­toral fel­low at the Univer­sity of Bri­tish Columbia (UBC). “Un­for­tu­nately, the po­ten­tial change of dis­tri­bu­tion of highly-valu­able species be­tween two neigh­bour­ing coun­tries will rep­re­sent a chal­lenge for fish­eries man­age­ment that will re­quire new treaties to deal with trans­bound­ary fish stocks.”

To avoid con­flicts, the study sug­gests that gov­ern­ments could dis­cuss more flex­i­ble ar­range­ments such as al­low­ing the trade of fish­ing per­mits or quo­tas across in­ter­na­tional bound­aries. Un­for­tu­nately, if ne­go­ti­a­tions fail, over­fish­ing and frac­tured re­la­tions may re­sult.
