AQUA ME Terminologies: Basic Concepts & Aquaculture

AQUACULTURE

 Aquatic farming; 

- it is the controlled growth of aquatic species in certain field or area.

• fish, oyster, mollusk, aquatic grasses etc.

PISCICULTURE

 Aquaculture practice involving finned fish

EXTENSIVE AQUACULTURE

- managed aquaculture dependent on the local natural setting,
- i.e pond or coastal bay area

INTENSIVE AQUACULTURE

- managed aquaculture controlled through human engineered means such as managing of water quality, temperature gradient and source of food.

FISH FARM

area used to grow populations of aquatic organisms, primarily fish

FISH HATCHERY

• one form of fish farm, managed with the intent of resupplying native wild population in natural environments.

• most likely intensive: after hatchery -> grow out phase

ORNAMENTAL FISH

• different kind of fish, 

• such as goldfish and koi which are typically grown to be kept in aquariums or small private ponds.

WATER QUALITY

• The Characteristics of water, such as O2-CO2 balance, Temperature and water contaminants, which define its 

1. ability to sustain aquatic organism and 

2. its purity from the chemicals.

• always test the water parameters

CULTURE TANKS

• Man-made holding areas used to rear fish farm stocks

• if there’s a pond, there’s a smaller container for culture

FISH HUSBANDRY

The breeding and rearing of fish for a variety of seasons.

BROODSTOCK

Fish of any particular species which are raised for reproduction purposes

ANADROMOUS FISH

Migratory fish that live in salt water but breed in fresh water i.e SALMON and STURGEON

CATADROMOUS FISH

Migratory fish that live in fresh water but breed in salt water  i.e Bangus or Milkfish

AMPHIDROMOUS FISH

Migratory fish that live in both fresh and salt water, regardless of breeding area  i.e Gobies or BIYA

OCEANODRAMOUS FISH

Fish that moves, thrive and breed within salt water only

POTAMODRAMOUS FISH

Fish that moves, thrive and breed within fresh water only.

FRY

Development stage of fish immediately after the larvae stage, at an age of less than a week

FINGERLING

Development stage of fish following the fry stage and continuing into the first three to four months of life

YEARLING

Development stage of fish following the fingerling stage and lasting until approximately one year of age

AQUACULTURE

• refers to Fishery operations involving all forms of raising and culturing fish and other fishery species in fresh, brackish and marine areas.

• is the practice of raising aquatic organisms

Broodstock

Farmers maintain select adults, or broodstock, for producing the next generation.

Hatchery

Eggs and larvae require optimal water quality and complex care.

Nursery

Juveniles receive lots of food and oxygen as they quickly grow under careful care.

Growout

Aquatic organisms moved to larger system with lower density to grow to the desired size.

Harvest

Farmers use nets and baskets of all shapes and sizes to harvest the crop for live sale or processing.

Market

Live or fresh US aquaculture product are delivered to market

Extensive System

• low stocking density

• no food input and depends only on natural food

• Oyster Farming

Semi-Intensive

• use of supplementary feeds and natural food

• Tuna Farming

Intensive System

• high stocking density

• less dependence on natural food availability and greater dependence on commercial feeds

• Tilapia and Bangus Farming
