The state of the world’s fisheries: A bleak pictureMaximum sustainable yieldThe problems with overfishing
World’s fisheries can’t sustain thepresent catch levels
By refining technology and methods, the fishing fleets are taking ever larger proportions of declining stocks
The Economics if Commercial FishingCompared to the industries involved with other marine
resources, the worldwide fishing industry is unique in that, according to economic estimates, the worldwide fish catch sells for less than it costs.
Global governments subsidize. Grants Low or no-interest loans Free or low cost fuel Tax incentives Price controls
Fishing fleets spend $124 billion to catch $70 billion in fish
That’s about $1.77 spent for every dollar earned Tax payers cover the overhead so that the fishing
industry makes a profit
