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.
