2. The International Union for Conservation of Nature is an
international organization working in the field of nature
conservation and sustainable use of natural resources.
Headquarters: Gland, Switzerland
CEO: Grethel Aguilar
Founder: Julian Huxley
Founded: 5 October 1948

4. 7.Increase Public Awareness
8.Various organization and conferences that research
biodiversity and associated conservation strategies that
help to identify areas of future research, analyse
current trends in aquatic biodiversity.

5. Aquatic ecosystem: conservation strategies
1.Maintain and conserve the distribution, diversity and
complexity of watershed area and landscape Features to
ensure protection of aquatic system
2. Maintain and conserve spatial and temporal connectivity
between and within watersheds, lateral, longitudinal,
drainage network connection
3.maintain and restore physical integrity of aquatic system
4.maintain and restore water quality necessary to support
healthy ripiarian, aquatic and wetland ecosystem

6. 5.Maintain sediment regime under which aquatic
ecosystem evoled it includes -timing
-volume
-rate
-Character of sediment storage And transport

7. Guidelines for Threatening Processes
A taxon may classified as threatened even if a
threatening process cannot be identified. Regardless of
nature of threats assessment must follow. And these
guidelines to ensure valid application of criteria.
There are five quantitative criteria are used whether
taxon threatened or not

8. After a species is evaluated by the IUCN, it is placed
into one of eight categories based on its current
conservation status.

9. The IUCN system uses a set of five quantitative criteria
to assess the extinction risk of a given species. In
general, these criteria consider:
1.The rate of population decline
2.The geographic range
3.whether the species already possesses a small
population size
4.Whether the species is very small or lives in a restricted
area
5.Whether the results of a quantitative analysis indicate a
high probability of extinction in the wild

10. Live Gene Bank
-Live Gene Bank establishment for the conservation of fish
germplasm is a new age concept of conservation of
fishery resources of the nation.
-The main aim of the gene bank is to study the life history
traits and breeding behavior of the threatened and
endemic fish species of a region.
-first Live Gene Bank established in 1962 at Fish Culture
Research Institute of Szarvas, Hungary, initiated with
culture of Common Carp and followed by 25 different
species with 30-100 individuals each is a glaring example
of such method of conservation.

11. Live gene banks could be established in/nearby the
natural habitats or in different habitats which are
believed safe. The key advantage of live gene banks is
the ability to restore the full genome of species in
concern.
Definition:

14. The Life Gene Bank is based for the collection,
acclimatization and breeding of wild fish species of
natural environment and their ex-situ conservation in
the Gene bank.
The live transport of fishes from rivers, hill stream and
wetlands are in fact a big challenge to maintain the Life
Gene Bank
Proper identification of the vulnerable areas based on
earlier research findings and secondary data from the
local fisherman is a useful tool for site selection and
collection of threatened fish species for Live Gene Bank.

15. The initial transportation of stocked fishes needs much
attention as the fishes are already weakened by the day
long captivity and stocked condition
The fishes are then unloaded into the water filled
rubber bag very cautiously with the help of plastic
bucket. Very few fishes are taken at a time to avoid any
physical injury to the fish due to crowding which might
lead to fish mortality.
After the immediate transfer of fishes into the rubber
bag, a fresh dose of antibiotic e.g. Teramycin (2mg/liter)
is used to remove excess ammonia from the water.
