When one is establishing an aquaculture operation, the need for more time to develop markets for the aquaculture products is the main reason to:

• begin with multiple production facilities.

• develop long-range expansion goals.

• invest heavily in the operation.

• start with a small operation.

• inspect the production tank.

• look for foreign material in the tank.

What is the main driving force behind the development of aquaculture?

• Worldwide fish catch rates have leveled off or declined

• Cost-effectiveness is much higher than traditional angling

• It is much easier to accomplish than traditional off shore fishing

• Wild fish are disease riddled, making the catch in many areas not safe for consumption

Which of the following is NOT a benefit of aquaculture?

• Reduces risk of fishery collapse

• Requires small amount of water, space and fuel

• Doesn't take up a vast amount of land space

Two of the least successful types of aquaculture facilities for large-scale fish production are:

• cages and levee ponds.

• raceways and watershed ponds.

• recirculating systems and cages.

• watershed ponds and cages.

Being too close to public waters or in a wetland may prevent construction of an aquaculture facility because of:

• boating guidelines.

• housing regulations.

• safety issues.

• zoning laws.
