Natural 2 (Unit 6)

Having a market for the fish that are produced is a prime consideration when:

• assessing the fish lab space or needs for the operation.

• dealing with a bank for a loan.

• deciding on the species of fish to grow.

• determining the size of the aquaculture facility.

What would Kayla expect to find if the dissolved oxygen level in a recirculating tank dropped below 3.0 ppm?

• broken pump

• cloudy water

• dead fish

• discolored fish

Watershed ponds and levees are the primary facilities used to produce:

• aquaculture crops.

• aquaponic crops.

• lily pads.

• tadpoles.

Members of Mr. Harris's natural resources class want to raise tilapia and lettuce without direct contact between the fish and lettuce plants. What can they construct to accomplish their objective?

• aquarium system

• passive aquaponics

• flow through system

Tonia notices her two fish lack much of an appetite. In addition, one fish has white spots on its scales, and the other has protruded eyes and a bloated belly. She determines that her two fish are:

• diseased.

• molted.

• overfed.

• underfed.

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.

The aquarium in Mason’s classroom is near the air conditioning unit, causing the water temperature in the tank to decrease. The temperature reduction causes the fish to:

• die.

• get sick.

• grow faster.

• stop eating.

The factor that will have the most impact on the successful operation of an aquaculture facility is:

• water quality.

• fish species.

• feed type.

• tank size.

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.

Preserving correct water quality is essential to maintaining healthy fish in an aquarium. In order for Marshall to make sure that the water in his aquarium was slightly acidic, he conducted a:

• bacteria test.

• dissolved oxygen test.

• nitrogen test.

• pH test.
