The seminar focused on fish biodiversity and conservation in India, detailing the types, distribution, and threats to fish biodiversity, as well as conservation techniques. It provided an overview of India's rich fisheries resources, highlighting the diversity in marine, brackish, and freshwater species, and addressing challenges such as over-exploitation and pollution. Key species and conservation efforts were discussed, alongside technical references and ecological zones significant for biodiversity.

3. What is biodiversity
 Father of biodiversity in - E.O. Wilson.
Define Biodiversity
“Biodiversity include of the particular area may be living
organisms ( plant and animal ) called biodiversity ”.
Define Fish biodiversity
“Fish species diversity is define as the number of spp. And
abundance of each spp. that live in a particular location ” .

4. Distribution of Biodiversity
 Flora and fauna diversity depends
on –
 Climate.
 Altitude.
 Soils.
 Presence of other spp.
 Most of the biodiversity concentrated in
tropical region.
 Biodiversity hotspot
 A region with high biodiversity with
most of spp. being endemic.
 India have to biodiversity hotspot .
 Himalayan region.
 Western Ghat,
 Indo-Burma.
 Sundaland.

5. Eastern Himalayas
 Tropical Asia-East of the Ganges-Brahmaputra lower lands, excluding
Malesian region.
 Covers an area of 2,373,000 sq.km.

6. Western Ghat
 The Western Ghat (Sahyadri Hills) is
formed by the Malabar Plains and the
chain of mountains running parallel to
Indias western coast.
 Travers the states of Gujrat, Maharashtra
Goa, Karnataka, Kerala and Tamil
Nadu.
 Cover an area of about 138,600 km.

7. Total fish biodiversity:
 World harbours total of 33059 spp,
4258 genera ,
442 families.
 About 58 % marine, 41 % fresh water, 1 % migrants.
 In India,
3231 fishes spp
113 Brackish water 2443 are marine water951 fresh water

12. types of fish biodiversity-
 1- Marine fish diversity.
 2- Brackish water fish
diversity.
 3- Fresh water fish diversity.
Marine Fish Diversity
The sea water surrounding
east and west coast of the
country with salinity more 30
ppt.decignated as marine
water.
 India has a long coast line more than
8129 km.
 Its marine resources are spread over in
the Indian ocean. Arbian Sea ,and Bay of
Bengal.

13.  The Andaman and Nicobar island and the coral island of Lakshadweep represents
one of the richest ripositories of biodiversity in the whole of south Asia
 These resources comprising 1368 taxa including the commercially important
Pelagic and Demersal species diversity.
 Commercially important species:-
Shark Spp Perches fishes
Carcharhinus sorrah Lethrinus spp.
C. dussumieri Epinephilus spp.
C. Gangeticus Silver bellies
S. Sorrahkowah Secutor muconius
Bombay duck Seer fish
Harpadon nehereus Scomberomorous guttatus
Oil sardine Mackerel
Sardinella longiceps Rastrelliger kanagurta
S. Fimbriatus Tuna
S. Gibbosa Auxis thazard
S .albella Pomfrets
Pampus argentius and so other fishes .

14. Species composition of some major
Demersal spp.
Elasmobranch –
 In india there are about 110 spp of elasmobranch which incudes
66 spp of sharks.
Sharks-
 The dominant spp of sharks are Chiloscyllium indicum (slender
bamboo shark ) ,C.griseum (grey bamboo shark ),Rhincodon
typus (whale shark) etc.

15. Whale shark
 Rhincodon typus is slow moving filter feeding carpet shark

Divers of river beds for urbanization
Destructive natural events ( flood ,tsunami,
cyclone, disease, Earthquakes ) etc .
Over exploitation of fish Unsustainable fishing Water pollution
Global climate variation

19. IUCN Categories of threatened species:-
Extinct (ex)
 A taxon is Extinct when these in no reasonable doubt
that the last individual has died.
Ceritically endangered (CR)-
Reduction of at least 80% over at least 10 years or 3
generation.
Endangered (EN)-
 Reduction of at least 50% over a least 10 years of
3 generations.
Vulnerable –
 Reduction of at least 2o% over at least 10 years or 3
generations.

21. List of Indian fishes in threatened category:
 Zoological Survey of India (ZSI) was the first who compiled a
list of 21 vulnerable fishes-
4 Endangered
Barilius bola
Puntius chilinoides
Semoplotus semiplotus
Enobarbicheilus maculatus
17 Threatened species
Notopterus chitala, Acrossocheilus hexagonolepis,Cirrhinus
cirrhosa,Labeo fimbriatus,Labeo potali,Labeo kontius,Puntius
carnaticus, P.curmuca, P.jerdoni, Tor khudree, T.putitora,T.tor,
Schizothorax richardsonii, Schizothoraichthys progestus, Silonia
children,Pangasius pangasius and Bagarius bagarius).

22. Techniques of conservation of
biodiversity
In-situ conservation:-
 It is the process of protecting an
endangered species in its
natural habitat Ex. - National
park, sanctuary.
Ex-situ conservation :-
 It is the process of protecting an
endangered species outside its
natural habitat ex – gene bank
,seed bank .
