Aquaculture Basics
The management of aquatic environments to increase harvests of usable plants and animals
Aquaculture
True or False: Several species of fish migrate from freshwater to saltwater.
True
True or False: Salinity measures the total mineral content of water.
True
True or False: Research in aquaculture is limited to finfish.
False
The part of the perch responsible for absorbing oxygen from water
Gills
Fisheries that occur naturally without human intervention
Natural fisheries
Frogs and turtles belong to this group of aquatic organisms
Amphibians
A method of measuring salinity in water
Electrical conductivity
Which species represents one of the fastest-growing aquaculture industries in the U.S.?
Catfish
The perch's fins responsible for forward movement
Caudal fin
The process by which water moves from an area of high concentration to low concentration through a selectively permeable membrane
Osmosis
The initial source of energy for the aquatic food chain
The sun
As the concentration of salt increases, electrical conductivity...
Increases
Name one challenge facing the aquaculture industry.
Obtaining pure water and returning water without pollution
Which organ helps perch maintain buoyancy in the water?
Swim bladder
Two examples of animals raised in aquaculture systems
Fish and shellfish
Aquatic organisms with exoskeletons, like crabs, belong to this group
Crustaceans
The presence of suspended matter in water causes this
Turbidity
As productive land becomes scarce, where will food production shift?
Oceans
The structure responsible for detecting vibrations and movement in the water
Lateral line
Understanding how organisms live, eat, grow, and reproduce in water are the duties of this career
Aquaculturist
Mobile aquatic organisms that grow into nonmobile adults start at this stage
Larvae
There are three factors that affect the concentration of dissolved oxygen in water. Name one.
Temperature, pressure, and atmospheric oxygen
What is one major problem aquaculturists face when using cage culture systems?
Pond rollover or stress from confined spaces
Produces and recycles red blood cells and supports the immune system
Spleen
