3. Introduction
The catching of fishes by equipments or
without equipment called “Fishing”.
In the fishing time, those equipments which
are use in fishing known “Fishing Unit”.
From the starting of fishing and up to delayed
the fishing process are called “Fishing Cycle”.
4. Principal of Fishing
Fishing are based on the three basic
thinks -:
1) Type of fishes
2) Nature of water body
3) Weather
5. Fish Gear
Those equipments which are used in fishing
called “Fish Gear”.
Fish gears like as -: Different type of net,
Traps, Hooks etc.
6. Method of Fishing
On the basis of use of gear, fishing are of basic
two types -:
1) Fishing without gear (Hand Fishing)
2) Fishing by gear (Gear Fishing)
7. Fishing by Gear
1) Fish Screens
2) Fish Traps
3) Line Fishing
4) Net Fishing
5) Fish Attraction Devices (FADs)
6) Electrical Fishing
8. Fish Screens
The screen are set to surrounded a shallow tidal
area at the time of high floods. When the flood
water recedes the fish are left behind in the
muddy pool and are collected.
Screen are also set to mark off shallow areas of
river.
By this method is employed to catch Carps,
Catfish, Murrells etc.
10. Fish Traps
Various type of traps are used to catch of fish
which are allowed and prevent from escaping of
fish.
It is also called as Cover-pot or Basket trap.
A large number of fisherman are together in
muddy water by this method.
Live fishes like : Channa, H. fossilis, Clarias
batrachus are easily catch by trapping.
12. Hooks & Line Fishing
Long-lining is one of the most fuel-efficient catching
methods.
This method is used to capture all type of fishes and also
able to perform in Rivers, Sea, Ponds, Lacks, Pools etc.
The lines may be set vertically in the water column, or
horizontally along the bottom.
The size of fish and the species caught is determined by
hook size and the type of bait used.
13. Types of Lining Fish Catching
Lining is a modern fishing method. Modern fishing lines are usually
made from artificial substances.
Lining method are basically divided into three types -:
1) Droplining - A Dropline usually shorter than longlines and
have fewer hooks. Droplines have a weight at the bottom and a float
at the top.
2) Handlining - It is a single fishing line method by a single
person. Handlining can be done from boats or from the shore.
3) Longlining - is a commercial technique that uses a long
heavy fishing line with a series of hundreds or even thousands of
baited hooks hanging from the main line by means of branch lines
called "snoods". Longlines are usually operated from specialised boats
called longliners.
15. Net Fishing
Netting is the principal method of commercial fishing.
The most common form of fishing for recreational
fishers is “net” called netting. It is mostly used by
commercial fisherman to catch fish in large scales.
While there are many types of nets, all rely on the fish
getting snared or caught in the net's mesh. Nets are
typically long, narrow and flat, weighted at the bottom
edge and supported at the top edge by floats.
16. Types of Net
1) Dip net or Lift net
2) Cast net
3) Purse net
4) Drag net
5) Shore sienes or Rampani net
6) Trawl net
17. Dip Net or Lift Net
Dip net are formed in a several shapes like : square
or rectangular, triangular, etc.
Dip net lowered into the water in the hope that
fish would swim over them and lifted out of water.
Lift nets can be categorized into four names -:
1) Hela Jal
2) Kharra Jal
3) Bhesal Jal
4) Khoursal Jal
19. Cast Net
It is also called “Ghagaria Jal”.
It is a circular net which is looks like the umbrella
shape.
It is extensively used in ponds and rivers and all
along the sea coast.
It is can’t be used in weedy place or rocky bottom
place.
21. Purse net
It is a purse shaped net and operated from a boat.
The net is then "pursed", drawing the bottom closed
and entrapping the fish.
Purse nets cannot be used by recreational fishers.
Two kinds of purse net are used to catching fishes-
1) Kharki Jal
2) Shangla Jal
24. Drag net
Drag net are used in a large skills in fishing.
Drag net are categorized in two types -:
1) Gill Net
2) Drift Net
25. GILL NET
It is also known “Fixed Net”.
Gill nets are walls of netting which may be set at or below
the surface, on the water bed, or at any depth in between.
Gill netting is probably the oldest form of net fishing,
having been in use for thousands of years.
Netting is almost invisible, fish swim right into it; and their
gills get caught
Different type of gill net are make for the caught of
different kinds of fishes.
28. DRIFT NET
• Large floating nets
• Unbreakable and invisible to most sea species
• likely to entangle large pelagic species : dolphins,
whales, sharks, turtles, and rays.
• Driftnets have earned the nickname “walls of
death”.
• These nets which are not anchored.
31. Shore sienes or Rampani net
Rampani nets are a wall of net divided into three
layers.
An inner fine-meshed net is sandwiched between
two outer, larger meshed nets.
Rampani Net are also two types -:
1) Fixed Rampani Bag Net
2) Moveable Rampani Net
33. Trawl Net
It is very efficient net for capturing bottom
fishes.
Trawl net is the conical bag like structure.
This net are of two types -:
1) Beam Trawl
2) Otter Trawl
36. Fish Attraction Devices
Various species of fish often associate with
other living creatures.
e.g. tuna associate with dolphins and whale
sharks.
Some associate with objects floating or
suspended in the sea.
This natural phenomenon has been
exploited to attract fish to floating or
suspended structures.
37. Fish Attraction Devices
Such structures can provide known locations for
congregating fish, around which vessels can
operate a wide range of fishing techniques
including purse seines, pole and line or trolling
FADs may be used to concentrate fish in
sufficiently high numbers which are then
surrounded with a purse seine net.
38. Use of explosives (dynamite)
or
poisons (sodium cyanide, bleach)
Dynamite fishing : In some countries such as the
Philippines, explosives (dynamite or blast
fishing) are used on coral reefs to capture fish.
Blast fishing is a particularly destructive method
of fishing and is prohibited in many regions.
39. ELECTRICAL FISHING
Electric fishing is a new technique has been
developed by using of low voltage electric current.
The fish always swim towards the positive pole of
electric current and electrode with increasing
potential.
The advantage of this method is that even the large
size of fishes which escape being caught by taking
shelter under stones, rocks etc., can be easily caught.
