Fishing species low on the food chain
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
According to the UN Food and Agriculture Organization the trend in world fish catch since WWII is
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
Industrial fishing is ____________ % of the world commercial fish catch
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
_______________% of the world's fisheries are overfisshed or depleted
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
Some doubt the UN Food and Agriculture Organization accuracy because
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
Indirect effect of fishing on the environment include
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
Response to the overfishing that make the problem worse are
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
____________ is taking no more fish than would affect future populations. Exceeding this is
can deplete species that feed on the fished species AND can allow competitive species to proliferate
a steady increase
between 50 and 70
independent analysis says fish catch yields are much smaller than reported
33
decline in species that feed on the fished species
use of new technologies and methods and fishing new fisheries
maximum sustainable yield, over fishing
