is indeed surrounded by various kinds of bodies of water like the sea, the ocean,
rivers, lakes and many more.
of the uses of country's water are: agricultural (patubig); bathing animals;
national marine parks. coral reef parks and reserves; fish ponds; fish and wildlife
sanctuaries; public water suplies like watersheds; scientific processes like
coagulation, sedimentation, filtration and disinfection; industrial water supply
like cooling; recreational water like boating, swimming and scuba diving.
we talked about water, fish is the first thing or creature that can be associated
with the topic. There are three sectors of fishing:
Fisheries - fishing within 15 kilometers from shore that do or do not
use fishing boats weighing 3 gross tons or less
Fisheries - uses big fishing vessels weighing greater 3 gross tons. These
vessels go beyond 15 kilometers from the shore and catch greater amount of
fish than the municipal fisheries.
- sector including fishponds
available in Municipal Fisheries:
available in Commercial Fisheries:
fewer than 2,000 varieties of fish are in the seas surrounding the islands and
in lakes, rivers, estuaries, and fish ponds. The most important commercial fishes
are milkfish (a herringlike fish), anchovy, herring, sardine, mackerel, grouper,
snapper, cavalla, mullet, barracuda, mudfish, and caesio. Fish are raised in
ponds in some provinces of Luzon and Panay. There are pearl beds in the Sulu
Archipelago to the south, and mother-of-pearl used for making buttons is exported
to China and elsewhere. Tortoiseshells and shells used for windows are exported
to Singapore, Malaysia, and other countries.
are some kinds of bodies of water:

sudden sheer descent of a stream or river over a steep drop in its bed, sometimes
in a free fall. The term cataract, usually designating a series of rapids
in a large river, is often applied to waterfalls of large volume. A waterfall
of any height that has a small volume of water or is one of a series of falls
is called a cascade. The term cascade is also applied to a waterfall if, while
plunging, it maintains contact with the streambed. The highest waterfalls
frequently are cascades. Waterfalls are valuable today as sources of hydroelectric
stream of water that flows along a channel from the highlands to the lowlands.
The great majority of rivers eventually discharge into either the sea or a
lake, although some rivers disappear due to water loss through seepage into
the ground and evaporation into the air.
the tidal area of the lower part of a river. Sea inlets, extending as far
as the tides are strongly felt, also have estuarine characteristics of varying
quality. There are usually three distinct but overlapping zones in an estuary:
an open connection with the sea where marine water dominates; a middle area
subject to strong salt and fresh water mixing; and a tidal river zone characterized
by fresh water. Variation in the seasonal discharge of rivers causes the limits
of these zones to shift, and this increases the overall ecological complexity
large, inland body of fresh or salty standing water. Lakes are distinguished
from bodies of water such as bays and gulfs, and some seas, that have an interchange
with the ocean and are subject to tides.
