This document discusses the different components and types of fisheries in India. It covers inland fisheries including capture fisheries from rivers, reservoirs, and lakes, as well as culture fisheries conducted on fish farms. It also discusses coastal fisheries including estuarine fisheries that provide nursery grounds for fish and brakishwater fisheries. Finally, it covers marine fisheries along India's east and west coasts and the types of fish found in each region.

1. INLAND FISHERIES AND AQUALCULTURE
TOPIC I: Components of Aquaculture:
Capture, Culture, Intensive, Extensive, Semi-
Intensive, Pen Culture, Cage Culture.

2. CAPTURE FISHERIES
Inland and Marine fishries

3. Distribution Of Water On Earth

4. Fisheries in India
Fisheries is divided into three main types:
• Freshwater Fisheries (Inland Fisheries)
• Brakishwater Fisheries
• Marine Fisheries
Inland Fisheries are of two types:
i) Capture Fisheries
ii) Culture Fisheries

5. i) Capture Fisheries: it is mainly concerned
with catching fishes from rivers(Riverine
Fisheries), Reservoir Fisheries, Lakes
(Lacustrine Fisheries), estuaries
(Estuarine Fisheries),
ii) Culture Fisheries: it is provided by small
water bodies (tanks, jheels, ponds etc.)
where important culturable fishes are
rared and bred on scientific lines by
constructing Fish Farm.

6. Riverine Fisheries In India
 Rivers in India constitute the backbone of
capture Fisheries.
 There are 114 major and minor rivers along
with their tributaries.

315,980 sq. Km (catchment area)
Catla catla Channa striatus

17.  Main fishes of Krishna river are :1401km
(length), 233,229 sq. Km (catchment area)
 Main fishes of Cauveri river are : 800 km

18. The Peninsular River System
 The Western Coast river system is also known
as Peninsular river system. It has two imp.
Rivers, namely: Narmada & Tapi.
 The Narmada originates in the Amarkantak
Hills, M.P & terminates in the Gulf of Cambay
after crossing Gujarat state.The catchment area
is about 94,235 sq.km.
 The Tapi river has its origin in Mount Vindhya
crosses through M.P, Maharashtra & Gujarat &
ultimately joins the Arabian Sea. The
catchment area is about 48,000 sq.km.

22. Crafts and gears
• Shallow waters
Nets: trap and cast nets
• Deep waters
Seines, drag nets, gill nets, drift net, dip net,
bag nets, fixed trap nets, hooks and lines.

24. RESERVOIR FISHERIES
• Reservoir is a natural or artificial place where water is
collected and stored for use, especially for supplying a
community, irrigating land, furnishing power etc.
• Cover more than 1% of the country’s land surface. Total
area : 31.5 lakh ha
• Yield : 20 kg/ha/yr
• Majorly used for Power generation, irrigation, flood
control, recreation.
• Fishery is considered as bye product.
• Major reservoir of India:
Beas dam, Pong dam, Pandoh dam, Gandhi sagar,
Hirakund, Rana partap sagar.

27. TYPES AREA (ha) NUMBER
LARGE > 5000 56
MEDIUM 1000 – 5000 180
SMALL <1000 19134
 Hirakud Reservoir is the largest reservoir in the country
with an area of 74592 ha .
 Peninsular states account for more than 56 % of the
total area . 94% of the small and 34% of the reservoirs
are here.
 T N has the maximum number of reservoirs (8906)
Karnataka(4679) and A P (2937)
 Present fish production from reservoirs is estimated at
0.94 lakh t
 Small reservoirs contribute the catches(74%)followed
by the large (19%)medium(7%)
 Average fish production of large and medium reservoirs is
13kg/ha(11- 15kg/ha) and that of small reservoirs is
50kg/ha

28. • Lentic water bodies and temperate
reservoirs develop thermal stratification due
to which reservoir has different fishery than
river and natural lakes.

29. Fishes
• Local fishes as well as exotic fishes.
• Catla catla, Labeo rohita, L. calbasu, and
Cirrhina mrigala,
• Cyprinus carpio spp.
• Reservoirs support natural hybridisation
which leads to production of intergeneric
hybrids.
• Gears used in reservoir fisheries:
Gill nets

30. LACUSTRINE FISHERIES
• A lake is defined as all large bodies of
standing water.
Zonation in lake

31. Fishes in lakes
Cold water species: trouts
Indigenous species: major carps, minor
carps, cat fishes, clupids, murrels etc
Game fishes: brown trout and rainbow
trout, mahseer.

33. THERMAL STRATIFICATION IN LAKES

34. ESTUARINE FISHERIES
• Estuaries are the water passages where
the river currents mix with the tides.
• Shallow, well oxygenated , temperature
varies with depth and season.
• More productive than river and sea.
• Serve as nursery grounds for juveniles
because conditions are conductive to rapid
growth.

35. Open estuarine fishery
RESIDENT FISH
•Ex: Mogul parsia,
Lates calcarifer,
Hilsa sinensis
ANADROMOUS
MIGRATORY
FISH
•Migrate from sea
to fresh water
rivers to spawn.
•Ex: Hilsa ilisha,
Polynemus
paradiseus
CATADROMOUS
MIGRATORY
FISH
•Migrate from
fresh water to sea

•Ex: Pangasius
pangasius

36. ANADROMOUS MIGRATORY FISHES
Hilsa ilisha
Polynemus paradisus

37. CATADROMOUS MIGRATORY FISH
Pangasius pangasius

38. Healthy estuaries can provide many different values
and perform many important functions.
 Flood control
 Nursery areas
 Migratory stopovers
 Recreation
 Production of biomass
 Safe harbor
 Feeding grounds

39. MARINE FISHERIES
Marine Fisheries:-The marine fisheries deal
with the fishing activities in the oceans and
seas.
Indian coast 4667 km. (Main Land)
Continental shelf 259 lakh sq. km.
West coast is more productive than east
coast.

40. West Coast and East Coast
Fishes
• Pomfrets
• Polynemids
• Clupeids
• Bombay duck
• Sardines
• Makerels
• Anchovies
• Soles, sharks and
rays
• Clupeids
• Silver bellies
• Seers
• Flying fishes
• Perches
• Sharks
• Rays
