PART 2: AQUA Flashcards
rearing and breeding of aquatic organisms on confined condition which is more or less controllable by am
aquaculture
uses freshwater supplied by spring, stream or river, rain, deep well or lake
freshwater aqua
uses combination of freshwater and seawater and is usually located in the mangrove areas where the river flows and mixes with the tidal water
brackishwatter
usually located in protected coastal areas and uses only seawater
mariculture
period of rising and falling of the water surface of the oceans, seas, bays, mouth of rivers, etc.
tidal phenomenon
published by the government by the bureau of coast and geodetic survey, this contains the compilation of tables of predicted time and height of high and low waters each day of the year
tide table
prediction for the specific area using the tidal differences and constants of the tide table
actual tide gauging
normal length of a step or stride of an individuak
pace
defined as the ratio of the measure distance and the number of paces made by an individual to cover the measured distance
pace factor
the angle that is referred from the north and south
bearing
a clockwise angle measured from a reference direction, usually north
azimuth
boundaries of the farm are plotted to scale and area is determined by planimeter
planimeter method
area is calculated from the coordinates of the farm
double-meridian distance method
are conducted on the farm site to detrrmine the nature of the ground relief of its characteristics
topographic surveys
provides the basic horizontal and vertical control in the planning and design of the fishpond
topographic map
is a complex of establishments consisting of ponds of various kinds, water control structures and supporting facilities
fish farm
is a section of fairly shallow water, used for the controlled farming of fish and other aquatic organisms and laid out in such a way that it may be easily and completely drained
pond
all the water course crosses the pond
barrage or terrace pond
only a part of the water course crosses the pond
diversion pond
the allowd water flow crosses all the ponds
linked ponds
each pond has its own individual water supply and outlet
parallel ponds
about 2 ft. (0.5-0.7m) deep; series of small ponds
nursery ponds
