Aquaculture Terms Ch.1
Brackish Water
A mixture of fresh and sea water; or water with a total salt concentration between 0.05 percent and 3.0 percent, or a salinity of 1 to 10 parts per thousand
Broodstock
Adult fish retained for spawning
Processing
All of the procedures to prepare a product of aquaculture for consumption.
Larvae
An immature form that must undergo change of appearance or pass through a metamorphic stage to reach the adult state.
Salinity
Concentration of sodium, potassium, magnesium, calcium, bicarbonate, carbonate, sulfate, and halides (chloride, fluoride, bromide) in water.
Self-feeders
Device that allows animals the choice of when to receive feed.
Grow-out
Facilities that produce crops (fish) from the seed.
Seed
Fertilized, matured ovule of a flowering plant, containing an embryo or rudimentary plant; any part of a plant that will reproduce, including tubers and bulbs; offspring or progeny.
Warmwater
Fish that spawn at temperatures exceeding 70 degrees F. The chief cultured warmwater species are bass, sunfish, catfish, and minnows.
Coldwater
Fish that spawn in water temperatures below 55 degrees F. The main cultures species are trout and salmon.
Harvesting
Involves the gathering or capturing of the fish for marketing and processing. Aquaculture harvesting is typically topping or partial or whole harvests.
Hatchery
Produce the seed or young fish
Monoculture
Raising a single species in a pond or enclosure
Mariculture
Raising of organisms in the ocean
Polyculture
Raising two or more species in the same pond or enclosure.
Aquaculture
The art, science, and business of cultivating plants and animals in water.
Agriculture
The art, science, and business of producing every kind of plant and animal useful to humans.
Culture
The business of producing, propagating, transporting, possessing, and selling fish or shellfish raised in a private pond, raceway, or tank.
Spawn
The mass of eggs deposited in the water by fishes, amphibians, ad other aquatic animals; to deposit eggs or sperm (milt).
Eggs
The mature female germ cell, ovum.
Husbandry
The occupation or business of farming
Fingerlings
The stage in a fish's life between 1 in. and the length at 1 year of age.
Incubate
To maintain at a favorable temperature and in other conditions promoting development of eggs until they hatch.
Aquifer
Underground water supply
Freshwater
Water containing less than 0.05 percent total dissolved salts by weight.
