What is biodiversity? Father of biodiversity- E.O. Wilson.  The term ‘biodiversity’’ encompasses the variety of all life forms on earth.  Define biodiversity – ‘’ Biodiversity include of the particular area may be living organisms (plant and animal) called biodiversity ’’. • Simple words in can be defined as the biodiversity . “Variety, variability b/w genes, spp. and ecosystem”.  Define fish diversity – “Fish Species diversity is defined as the number of species and abundance of each species that live in a particular location”. The number of species that live in a particular location is called species richness. India is one of the 17 mega biodiversity countries having four biodiversity hotspots namely the Western Ghats, eastern Himalayas, Indo-Burma and Sundaland that are included amongst the top ten most important hotspots in the world. It also has rich freshwater(rivers, irrigationcanals,tanks, lakes,reservoirs) fish diversity.  Which living organisms– All living organism in world 7.4 billion. Fish Biodiversity in world- World harbour total of 33059 spp. 4258 genera, 482 families about 58 % Marine water, 41% Fresh water and 1% migrants. 2-Fisheries resource of India – India blessed with huge aquatic resources with 29,000 km of rivers, 0.3 million ha of estuaries, 0.9 million ha of back waters and lagoons, 3.15 million ha of reservoirs, 0.2 million ha of floodplain wetlands, 0.72 million ha of upland lakes and 2.02 million km sq area of Exclusive Economic Zone (EEZ) surrounding the seas,8129 km of coast line, which includes those of Andaman and Nicobar and Lakshadweep Islands. The seas surrounding the country, 14 major rivers, 44 medium rivers and innumerable small rivers and other inland water bodies provide one of the richest faunastic resources of the world.

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 From - CMFRI 2017

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.

Fresh water fish diversity of India  There are about 951 species of fresh water fishes are recorded from Indian waters .  In India there are 14 major river systems and 44 medium river which supports a number of diversity of fishes. Fresh water species  Some commercially important carps of India are Catla catla, Labeo rohita, Cirrhinus mrigala, L.calbasu, L.fimbriatus ,L. bata, Cirrhinus cirrhosa, C. reba .  Some important catfishes are Mystus seenghala , M. aor,Wallago attu , Pangasius pangasius , Silonia silondia , Bagarius bagarius etc .  Fresh water farming is mainly focused on Indian major carps .

18

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

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.

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 .
