Abiotic: Factors that are non-biological in nature but
still play an important role in the organisms environment.
Aquaculture: The keeping, breeding, hatching or culturing
of fish (FRMA 1994).
Biodiversity: A diversity of species of plants and animals.
Broodstock: Animals that are used as breeding parents to
obtain young stages for aquaculture.
Carrying capacity: The total number of individuals of a
population that a given environment can sustain.
Catadromous: A catadromous fish spawns in salt water but
spends most of its life in freshwater.
Ecologically Sustainable Development: Using, conserving
and enhancing the communitys resources so that
ecological processes, on which life depends, are maintained, and
the total quality of life, now and in the future, can be increased.
Ecosystem: A community of organisms interacting with one
another and the environment in which they live.
Ecotourism Tourism which involves no degradation of the environment
and which features places of ecological interest.
Fecundity: The number of eggs produced per female per unit
time (often: per spawning season).
Fish Any aquatic organism, excluding aquatic mammals, aquatic
reptiles, aquatic birds, amphibians or pearl oysters.
Fishery: A unit determined by an authority or other entity
that is engaged in raising and/or harvesting fish. Typically,
the unit is defined in terms of some or all of the following:
people involved, species or type of fish,
area of water or seabed, method of fishing, class of boats and
purpose of activity.
Fishing effort: The amount of fishing gear of a specific
type used on the fishing grounds over a given unit of time e.g.
hours trawled per day, number of hooks set per day or number of
hauls of a beach seine per day.
Mariculture A subset of aquaculture where the activities
involve marine and/or estuarine species.
Natural mortality Deaths of fish from all causes except
fishing (e.g. ageing, predation, cannibalism, disease and perhaps
increasingly pollution). It is often expressed as a rate that
indicates the percentage of fish dying in a year;
e.g. a natural mortality rate of 0.2 implies that approximately
20 per cent of the population will die in a year from causes other
than fishing. e.g. a natural mortality rate of 0.2 implies that
approximately 20 per cent of the population will die in a year
from causes other than fishing.
Population The total number of organisms in a species.
Productivity Relates to the birth, growth and death rates
of a stock. A highly productive stock is characterized by high
birth, growth and mortality rates, and as a consequence, a high
turnover and production to biomass ratios (P/B). Such stocks can
usually sustain higher exploitation rates and, if depleted, could
recover more rapidly than comparatively less productive stocks.
Recruitment The amount of fish added to the exploitable
stock each year due to growth and/or migration into the fishing
area. For example, the number of fish that grow to become vulnerable
to the fishing gear in one year would be the recruitment to the
fishable population that year. This term is also used in referring
to the number of fish from a year class reaching a certain age.
Refugia Areas in which flora and fauna species are able
to survive despite the impacts of major threatening processes,
for example, those associated with environmental or ecological
Resnagging Replacing snags in waterways.
Stock A group of individuals in a species occupying a well
defined spatial range independent of other stocks of the same
species. Random dispersal and directed migrations due to seasonal
or reproductive activity can occur. Such a group can be regarded
as an entity for management or assessment purposes.
Stream flow The amount of water passing a particular point
in a stream or river.
Sustainable fishery A fishery that is consistent with ESD,
that is, a fishery that uses, conserves and enhances the communitys
resources so that ecological processes, on which life depends,
are maintained, and the total quality of life, now and in the
future, can be increased.
The commons Common property, that is, there are no restrictions
to accessing the fish resource.
Translocation The transfer of aquatic organisms outside
their natural distributional range.
fish: Easily caught fish. High levels of activity and metabolism.
Inactive fish: Hard to catch fish. Low levels of activity
and metabolism. Can be due to weather and water conditions, or
they could be full of food and at rest.
Suspended fish: Fish at mid water depths.
Points: Long finger like spurs and points that run from higher
elevations into the river channels.
Breaklines: An abrupt change in contour or elevation.
Flats: Flat and often featureless country.
Channel: The bed of a river, stream or gully.
Drop off: Extreme contour change being near vertical.
Cove: small area of water between two spurs of land.
Bay: Large area of water between spurs of land.
Isolated structure: Significant obstruction lures are often
lost ie. Stump log or rock.
Feeder creek: Small tributary running into a larger river
Headwater: Term used for describing the main river that
fills a lake.
Weedline: An abrupt edge, of surface or subsurface vegetation.
Timberline/ brushline: An abrupt edge of dead or living
timber or small shrubs.
Main lake basin: Where significant proportions of lake
water is stored over a large area.
Catchment: A geographical area where waters drain via a
major river system. Mountain to sea.
Forage: Baitfish, insects and crustacea that fish eat.
Lake zones: The water in a lake can be divided up into
The part of a fish finder that goes into the water. It sends &
recieves the radio frequency
Global Positioning System
Chart Plotter: a electronic device that shows (on a screen)
a background map of the water & land. Usually shows depth
contours, tide information, navigation aids / beacons. Normally
requires a chart to be inserted into the unit.
Bricked: A term used to describe when a fish runs into
rocks or snags & hangs your line up. Also a method to make
camels drink more water.
Skunked: Went fishing and caught nothing. Not happy....
Boof: Loud noise associated with a surface feeding fish
or surface strike. Also used to descibe your fish mates appearance
- "Boof Head".
FIGJAM: F*$k I'm Good Just Ask Me. Term to descirbe egotistical
person. He's a bit of a FIGJAM isnt he...
TIUTA: Takes It Up The Ar$e. This spot TIUTA......
