Answer to Question 1ANS:An
aquaculturist is a person trained in production of plants and animals in water environments. He or
she must understand where and how organisms live, eat, grow, and reproduce in water.
Answer to Question 2ANS:Cage
culture can be designed for both natural waters and newly constructed ponds. Aquaculturists
have a better idea of growth rates and can adjust feeding ratios more economically. Some growers
have reported problems when a pond rolls over (i.e., changes in water quality occur suddenly during
certain weather conditions, bringing the less oxygenated water from the lower levels of a pond or lake
to the surface). Fish in cages are unable to move and can be stressed or killed. In this intensive
production system, the aquaculturist must ensure adequate nutrition, disease control, predator control,
and physical maintenance. The young stock must be legally caught from natural waters or produced in
controlled hatcheries. Successful operations include the production of Atlantic salmon off the coast of
Norway, Nova Scotia, and Maine. Hybrids of striped bass have been cultured in cages in Maryland and
California. Trout have been cultured in net pens suspended in mountain streams and ponds.
