Fish farming is an act of rearing fish for commercial purpose. This involves building the earthen, tarpaulin or concrete pond, fertilizing the pond, stocking the fingerlings in good water and feeding the Mackerel, Tilapia or catfish till market size.
While there are thousands of fish species all around the globe, only very few of them are viable for commercial fish farming.
Introduction to Fish Farming
Fish farming is known as pisciculture, that is, the breeding, rearing, and transplantation of fish by artificial means.
While fish naturally lives inside rivers, pisciculture is the means by which we grow fish at home, mostly for commercial purposes.
Fish farming is the major form of aquaculture (farming of aquatic organisms like fish, crustaceans, molluscs and aquatic plants).
Fish farming involves raising fish commercially in ponds, tanks or enclosures.
There are hundreds of species of fish, among which are; sea trout, cyprinids, pangas catfish, freshwater fishes, silver seabream, common carp, catla, greasy grouper, bighead carp, Nile tilapia, grass carp (who knows, maybe there are thousands more?).
However, most of the species of fish are not suitable for fish farming business in Nigeria, either because of their nature or because of the low demand in the fish market or the profitability of their species.
That’s why the most common fish species fish farmers grow for commercial purpose are carp, salmon, tilapia and catfish (while the last two,
catfish and tilapia is the most common species in Nigeria fish market).
Means of Growing Fish
Fish could be grown in two ways:
Extensive aquaculture where fish grow under natural water (i.e. river or stream).
Then, intensive aquaculture where fish are fed with external food supply.

SNAKEHEAD FISH
The snakeheads are members of the
freshwater perciform fish family Channidae , native to parts of Africa and Asia. These elongated, predatory fish are distinguished by their long dorsal fins , large mouths, and shiny teeth. They breathe air with gills, which allows them to migrate short distances over land. They have suprabranchial organs which develop when they grow older, [2] which are primitive forms of labyrinth organs. The two
extant genera are Channa in Asia and
Parachanna in Africa, consisting of about 40 species.
They are valuable as a food source and have become notorious as an intentionally released
invasive species .
Description
The various species of snakeheads differ greatly in size; dwarf snakeheads , such as
Channa gachua , do not surpass 25 cm (10 in) in length. Most other snakeheads reach between 30 and 90 cm (12 and 35 in). Five species ( C. argus, C. barca , C. marulius , C. micropeltes , and C. striata ) can reach 1 m (3 ft 3 in) or more. [3]
Snakeheads are thrust-feeders that consume
plankton , aquatic insects , and mollusks when small. As adults, they mostly feed on other fish (such as carp ) or on frogs. In rare cases, small mammals such as rats are eaten.
History
The Channidae are well represented in the fossil record and known from numerous specimens. They likely originated in the south Himalayan region of the Indian subcontinent (modern-day northern India and eastern Pakistan) at least 50 million years ago (Mya), during the Early Eocene epoch. Two of the earliest known species, Eochanna chorlakkiensis Roe 1991 and Anchichanna kuldanensis Murray & Thewissen, 2008, have both been found in the Middle Eocene of Pakistan. [1][4] By 17 Mya, during the Early Miocene, Channidae had spread into western and central Eurasia, and by 8 Mya, during the late Tortonian , they existed throughout Africa and East Asia.

Fish Meal
Fish meal is a commercial product made from both
whole fish and the bones and offal from processed
fish. It is a brown powder or cake obtained by
rendering pressing the whole fish or fish trimmings
to remove the fish oil. Fish meal is a rich protein
source and is used as an ingredient in feed stuff in
the aquaculture, poultry and dairy industries.
Fish Meal Of Specification:

New Fish Species Discovered in India
INDIA - Four new species of fish have been
discovered in Kerala.
The new species have been named Puntius nelsoni,
Puntius nigronotus, Systomus chryseus and
Systomus rufus, said Mathews Plamoottil, a zoology
professor at Kollam's Baby John Memorial
Government College, reports TheTimesOfIndia.
"Detailed articles describing these new species
have been published in international publications
like the Journal of Research in Biology and the
International Journal of Fauna and Biological
Studies," Mr Plamoottil told IANS.
Elaborating, he said the body and fins of Puntius
nelsoni are yellowish in colour, the head is deeper,
the snout shorter and the mouth wider. It was
discovered at Kallumkal in Thiruvalla, at the place
where Pamba and Manimala rivers merge.
The Puntius nigronotus was discovered at
Mananthavady in the hilly Wayanad district. Its
dorsal fin is black in colour, the lateral line scales
are greater than its closest relatives and its dorsal
fin has more rays.
Systomus chryseus was discovered from
Keezhvaipur near Thiruvalla. It is golden in coloured
and its pectoral fin is greatly elongated.
Systomus rufus was discovered from Venpala, also
near Thiruvalla. Its fins are red in colour.
"It is interesting to note that a new species of the
genus Systomus is being discovered after one-
and-a-half century from Kerala. All the four new
species have received a Zoo bank register number
from the International Commission of Zoological
Nomenclature, the worldwide scientific authority for
naming new animals. The new fish have been
deposited in the museum of the Zoological Survey
of India at Kolkata and Kozhikode," the professor
said........ reporting #

DON'T FEEL REJECTED

Have observed it so many times that when
people in the society rejects you that
doesn't mean you can't achieve your goals
in the society....
Many people can condemn you through
your good works but remember the case of
Jesus that in His hometown His own people
rejected Him as well and He doesn't feel
rejected because He needs to fulfill His
promises.
Don't be feel rejected because of your
status in the society because your destiny
may be feel superior more than before later
in life........... #

Fish - Anatomy
Can someone tell me if the following is true
Fish have very good eyesight and can see in all
directions at the same time
Fish have airbag which help to stay upright
Eyesight depends on the fish. Many fishes
have protruding eyes on the side of the head,
so they can see all around, but not all do.
Flatfish have both eyes on one side of the
head, so they certainly can't see in all
directions, but since they lie flat on the
bottom, it doesn't matter. For many fishes the
lateral line is more important.
2nd question: see gas bladder
This article lacks general Fish anatomy. Some
facts that apply to most Fishes will be useful.
Ecology section and Fishing should be
mentioned.
Fish points
Some common misconceptions about fish should
be added such as:
i)Do fish sleep?
ii)Do fish defacate or urinate?
iii) Do fish drink (sea/ocean)) water?
iv) Can fish hear?

Flying fish Facts
Flying fish is one of the most interesting types of
fish due to its ability to glide through the air. There
are 40 different species of flying fish that can be
found in all oceans of the world. They prefer
tropical and subtropical water of Atlantic, Pacific
and Indian Ocean. Flying fish are especially
abundant in the Caribbean Sea. Barbados was
known as the "The land of flying fish" in the past.
Flying fish are often hunted by fisherman. Luckily
their number in the wild is still stable and they are
not listed as endangered species.
Interesting Flying fish Facts:
Size of flying fish depends on the species. They
are usually 7 to 12 inches long.
Upper side of the body of flying fish is bluish-
grey. Their belly is grayish-silver. Flying fish
has forked tail. Lower piece of the tail is longer
than upper piece.
Pectoral fins of flying fish can be spread into
wing-like shape. Certain species have pelvic
fins shaped like wings also, and they look like
they have two pairs of wings.
Flying fish are shaped like torpedo. Their fins
are closed when they swim to ensure faster
movement through the water.
Before it emerges above the water, flying fish
accelerates toward the surface of the water
with the speed of 37 miles per hour. When
required speed is accomplished, flying fish
jumps out of the water and spreads its wings.
Flying fish can reach the height of 4 feet in the
air, and glide distance of 655 feet before
returning back to the water.
Flying fish can travel distances of 1.312 feet
without rest. This is important because it
ensures quick escape from predators.
Main predators of flying fish are marlin, tuna,
swordfish, mackerel and humans.
Flying fish swims in large schools (groups).
This feature is especially appreciated by
fishermen that can catch large number of fish
when they bump into a single school.
Flying fish are very sensitive and easily
attracted by the light (fishermen use light to
guide flying fish toward their ships). Despite
that fact, flying fish hunts mainly during the
night.
Flying fish eats plankton, bacteria and other
tiny marine creatures.
Mating season of flying fish takes place when
the ocean currents are the weakest. Depending
on the ocean, it can be during the spring of
autumn.
Flying fish live in large groups and their number
can exceed million individuals during the mating
season. Females deposit large number of eggs
near the surface of the water.
Eggs are usually attached to the floating debris.
Young flying fish have whiskers near the
mouths, and they look like the underwater
plants. This appearance ensures survival during
the first few days of life, when the youngsters
are the most vulnerable.
Average lifespan of flying fish is around 5 years
in the wild.......... #
