Fisheries : Fish Farming-Con
- Do fish farms really add to the world's supply of fish?
-- While ocean fisheries are in decline, commercial fish farming or aquaculture is booming. Farmers now produce more than one-fourth of all the finfish and shellfish worldwide. This rapid rise in aquaculture production "is a mixed blessing, however, for the sustainability of ocean fisheries."

- Fish farm feed depletes ocean stocks
-- Each year, some 80 million tonnes of wild fish are caught from the world’s oceans. Nearly one-third is used to make feed for farmed fish. The irony is that fish farming is widely viewed — and marketed — as a way to take pressure off wild fish.

- Fish farming lessens quality
-- "Fish farming has been practiced worldwide for thousands of years. However, in recent years, corporate interests have responded to the increasing public demand for fish in industrialized countries. Large corporate interests have emphasized profits over sound farming practices and, in the protein deprived developing countries, raising fish for export instead of feeding poor people."

- Hatcheries spread diseases
-- New research shows that hatchery-reared fish can spread a fungus implicated in the mass deaths of amphibian embryos in the Pacific Northwest. This is the first evidence that fish- stocking can spread amphibian diseases.

- Hatchery-produced fish are too expensive
-- Economists have figured out the cost of Columbia Basin salmon returning from the sea, and it is higher than expected. The cost per fish: $64.35 for a fall chinook, $179.39 for a steelhead, $4,646.17 for a chinook from the Nez Perce Tribal Hatchery, and $7,437.50 for a protected sockeye salmon from the Eagle Hatchery in Idaho.

- More Harm Than Good?
-- "While fish farming on balance still adds to the world's fish supply, some trends are headed in the wrong direction. Many types of aquaculture are hastening a worldwide fisheries collapse through practices that rely too much on feeding wild caught fish to farmed fish. Some aquaculture systems also reduce wild fish supplies by destroying fish habitats and collecting wild fish to stock fish farms. So concludes a recent paper in the journal Nature."
