Objective 4.03 4.04 Agriscience

Hope must monitor her aquaculture production system very carefully since the system
confines fish in floating pens because fish:
1. Are subject to electrocution during storms.
2. Can not escape stressful water conditions by moving to other parts of the pond.
3. Must be encouraged to get enough exercise to stir up the oxygen levels in the pens.
4. May become entangled in filters designed to purify the water.

is:
1. Angus.

4. Charolais.
Broilers are a type of chicken that are MOST often used for:
1. Fighting.
2. Laying eggs.

4. Show.
What was the MAJOR reason exotic breeds of cattle were imported into the United
States?
1. Consumers demanded leaner meat.
2. Disease wiped out the English breeds.
3. Producers wanted smaller calves.
4. To produce quality meat from dairy breeds.
