Prawn farming plays an important role in the economy of India. Despite of several problems, the practice of prawn farming has offered opportunity to increase incomes for farmers and associated groups. The future for prawn farming is bright but requires dynamism to exploit fully. The realization of its potential must be aided by improvements in production technology and hatchery operation. In addition, research in areas such as seed and feed production may need to be given particular attention, considering existing technology, the transfer, adaption and development of new technology.

Marine fisheries regulation act (mfra), and its amendments of gujrat and dama...Ashish sahu
Marine Fisheries Regulation Act
An Act to provide for the regulation of fishing by fishing vessels in the sea along the coast line of the State. (1) This Act may be called the Kerala Marine Fishing Regulation Act, 1980. (2) It extends to the whole of the State of Kerala.
Ocean acidification is the ongoing decrease in the pH value of the Earth's oceans, caused by the uptake of carbon dioxide (CO 2) from the atmosphere. ... When carbon dioxide dissolves into seawater, it forms carbonic acid (H2CO3). Ocean acidification impacts many species, especially organisms like oysters and corals.
Ocean acidification reduces the amount of carbonate, a key building block in seawater. This makes it more difficult for marine organisms, such as coral and some plankton, to form their shells and skeletons, and existing shells may begin to dissolve. ... The impacts of ocean acidification are not uniform across all species.
Mangroves and their importance with Threats iucn pptAshish sahu
A mangrove is a shrub or tree that grows in coastal saline or brackish water. ... Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action.
Mangroves are defined as assemblages of salt tolerant trees and shrubs that grow in the intertidal regions of the tropical and subtropical coastlines. They grow luxuriantly in the places where freshwater mixes with seawater and where sediment is composed of accumulated deposits of mud.
Fisheries crime and their sollution pptAshish sahu
What is fisheries crime?: Fisheries crime is an ill-defined legal concept referring to a range of illegal activities in the fisheries sector. These activities – frequently transnational and organized in nature – include illegal fishing, document fraud, drug trafficking, and money laundering.
Illegal fishing is a key driver of global overfishing, it threatens marine ecosystems, puts food security and regional stability at risk, and is linked to major human rights violations and even organized crime.
Iconic species are socially, culturally and economically important, and the community expects them to be effectively managed and protected.
What is a flagship species? A flagship species is a species selected to act as an ambassador, icon or symbol for a defined habitat, issue, campaign or environmental cause. ... Flagship species are usually relatively large, and considered to be 'charismatic' in western cultures.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

2. Ghost shrimp, also called glass shrimp, are
small, transparent shrimp commonly sold
as aquarium pets or fish food.
While several species are referred to by the
same name, they can all be cared for in the
same basic way.
If the shrimp are kept in a comfortable
environment with no predators, they can
breed rapidly
Introduction:
3. Preparing a Good Breeding Environment
Purchase a large fish tank
•Your fish tank should hold about 1 gallon (4 L)
of water for each shrimp.
• No matter how many you have, ghost shrimp
will be most comfortable in at least 10 gallons (40
L) of water.
•If you have to keep your shrimp in a tank
smaller than 10 gallons (40 L), allow 1.5 gallons (6
L) or more for each shrimp to make up for the
small space.
4. Purchase a second tank for
breeding
The hardest part of breeding ghost shrimp is
keeping the young shrimp alive.
If you let the eggs hatch in the same tank as the
adult shrimp, the young could be eaten by the
adults.
This second tank doesn't need to be as large as
the first, but a larger tank will give the young
shrimp the best chance at survival.
5. Use any filter for the main tank,
and a sponge filter for the
breeding tank.
Filters are necessary to keep aquarium water clean.
Most filters suck the water in to clean it, but these
can kill the tiny ghost shrimp young. Use a sponge
filter instead to avoid this possibility.
If your tank is larger than 10 gallons (37.9 L) and
contains fish as well as shrimp, you should use a
hang-on or canister filter to provide better cleaning.
Never use anything besides a sponge filter for the
breeding tank.
If you don't want to buy a sponge filter, you can
cover your filter's water intake with a sponge or a
piece of nylon stocking.
Alternatively, if your filter intake is too weak to
suck in adult shrimp, you can disconnect the filter
before the young hatch and replace 10% of the
water volume in the tank every day until the young
are fully grown and you can turn the filter on again.
6. Install an air pump in each tank.
•Like most aquarium pets, ghost shrimp need air
pumped through the water in order to breathe.
Without an air pump, the water will run out of
oxygen and the shrimp will suffocate.
7. Cover the bottom of each tank
with sand or gravel.
•Sand or light gravel will keep the shrimp
transparent, while dark gravel will cause them to
develop small specks and make them more visible.
Pick any color and type you like.
8. Fill the tanks with appropriate
water.
•Many places treat tap water with chlorine, so treat it
with a dechlorinator or chloramine remover to make
it safe for animals.
•At the very least, leave it out for 24 hours before
adding the shrimp so some of the chlorine will
evaporate.
9. Keep the water at 65-82º F (18-28º C).
•This is the broad range of temperatures ghost
shrimp are comfortable in, but many people
prefer to stick near the center of this range.
• Put a thermometer in the tank to check the
water temperature, and use an aquarium tank
heater if you keep the shrimp in a cold room.
10. Add live plants and hiding places.
•Ghost shrimp feed off the debris that falls from plants,
but you can keep them with just store-bought food if
you'd prefer not to deal with plants.
•Aquarium plants with fine, thin leaves are the best to
use, such as hornwort, cabomba, and milfoil.
• If kept in a tank with other fish, small flower pots or
other containers should be placed upside down to
provide hiding places only the shrimp can enter.
•For best results, give your plants about a month to
stabilize the chemical levels in the tank. Sudden changes
in nitrogen levels or other chemicals could kill your
ghost shrimp.
•Adding plants to the breeding tank in advance is
strongly recommended, as plant debris is one of the few
foods small enough for the shrimp young to eat. Many
people use Java moss in their shrimp breeding tank,
which may trap food debris to help the young shrimp
11. Storing the Crabs
Buy high quality shrimp for pets , and feeder
shrimp if you're breeding them as animal food.
"Feeder shrimp" are bred to produce high numbers
of young, but they tend to be more fragile and have
shorter life spans.
Well treated ghost shrimp should live for a couple
of years, and will be much easier to care for and
breed.
The seller should know which type of ghost shrimp
he sells.
You can also guess based on the living conditions:
if the shrimp are kept in a cramped space without
many plants, they are probably feeder shrimp.
12. Introduce the shrimp to the new
water slowly.
•Float the bag of water with the shrim inside on
top of the tank's water.
•Every 20 minutes, dispose of 1/4 of the water
from the bag, then replace it with water from the
tank. After you've done this three or four times,
pour the bag out into the tank.
•This lets them adjust to the temperature and
chemical change slowly.
13. Feed the shrimp tiny amounts of
fish food.
•Shrimp are active scavengers, but while they
can live off algae and plant debris if required,
you should encourage reproduction by giving
them a minuscule daily allotment of fish food.
•A single crushed pellet a day can sustain six
adult shrimp.
•If you keep other fish in the tank, use sinking
pellets, since the shrimp will not be able to
compete for floating food with larger animals.
14. Change the water once every
week or two.
•Even if the water looks clear, chemicals could
be building up that prevent the shrimp from
thriving.
•Change 20-30% of the water every week for
best results.
•Make sure the water temperature of the old
and new water is the same to avoid stressing
the aquarium's inhabitants.
•Changing 40-50% of the water every other
week may also work, especially if the tank
doesn't have many fish or shrimp for its size.
15. Be cautious about adding other
fish to the tank.
•Almost any medium to large fish will eat ghost
shrimp, or at least spook them enough to make
breeding difficult.
•If you want a more varied tank, add snails and
small fish only.
•If you have decided not to use a breeding tank,
do not include any fish at all in the single tank
you have.
•The adult shrimp will already eat many of the
young shrimp; with additional predators, not
many young will survive to adulthood.
16. Check that you have both males
and females.
•Adult female ghost shrimp tend to be much
larger than males.
•The size difference is significant, so you should
be able to tell the difference easily once your
shrimp are full grown.
•You don't need equal numbers of each. One
male for every two females is plenty.
Hatching and Feeding the Young Shrimp
17. Look for females carrying eggs.
•If you've cared for your ghost shrimp properly,
the females should produce eggs every few
weeks at least.
•These are bunches of 20–30 tiny green-grey
eggs attached to the females' legs.
•These legs, or "swimmerets", are short limbs
attached to the lower body of the female, so it
may look like the eggs are attached to the
female belly.
•Look from the side of the tank for the best
view, and get someone with sharp eyesight to
help you if the babies are hatching before you
see the eggs.
18. After a few days, transfer females
carrying eggs to the breeding
tank.
•Give the males a chance to fertilize the eggs,
then transport the females.
•Use a net to catch the females and quickly
move them to the prepared breeding tank
without other shrimp or fish.
•Move the breeding tank nearby and transfer
directly if possible; females have been known to
drop their eggs when stressed, so don't make
the transfer prolonged.
19. Wait 21–24 days until the eggs
hatch.
•Keep checking on the female to watch the
progress of the eggs.
•Near the end of the process, you might be able
to see tiny black dots within each egg: these are
the baby shrimps' eyes! When the eggs finally
hatch, the female will swim upwards and flick
the young off of her legs a few at a time.
•Don't disturb the female if you see her flicking
the young away, as they need to be deposited
within an hour in order to feed.
•She may take a while to do this, since in the
wild the young have a better survival rate if she
deposits them in different places.
20. Transfer the female back to the
main tank.
•After she is done depositing the hatched
young, move the female back to the other tank.
•The parent is no longer needed in the young
shrimp's life, and in fact may attempt to eat her
children.
•Once the young shrimp are alone and moving
about on their own, you may not even be able to
see them, as they are extremely tiny when
newly hatched.
•Continue to add food to the breeding tank for
three weeks even if you don't see them.
21. Feed them small amounts of
specialized tiny food.
•For the next week or two, these shrimp will
float around in the larvae stage, and have
extremely tiny mouth parts.
•Your breeding tank should already have plenty
of plants and algae to provide debris small
enough for them to eat, called "infusoria".
• You should still supplement this with any of
the following types of food, but remember the
shrimp only need tiny amounts:
•Storebought "rotifers" food, baby brine shrimp,
microworms, or powdered spirulina algae are
all suitable for young ghost shrimp.
22. •You can buy "fry food" intended for young fish,
but be sure to select powdered fry food suitable
for "egg layer" sized animals.
•Strain small pieces of egg yolk through a fine
mesh strainer if you don't want to use
storebought food.
•Java moss may help trap food for young
shrimp to eat, but don't add or remove plants
while larvae are in the tank, as it could disturb
the chemical balance of the water.
23. Feed them the same food as
regular shrimp once they've
grown legs.
•The surviving larvae will enter the juvenile
phase, and look just like miniature adults.
•AT this point they can feed off regular food,
although you may want to crush pellets and
other large food items to help them out.
24. Transfer the shrimp back to the
tank once fully grown.
•The shrimp will grow all their legs and develop
into miniature versions of the adults after 1 to 2
weeks.
• After 5 weeks, they will be fully grown and
can be transported back to the other tank.
•If you have a younger batch of eggs or larvae in
the breeding tank, move the larger shrimp out
after 3 to 4 weeks.
25. Don't transfer the females if it
causes the eggs to fail.
•Transferring the females to the breeding tank can stress
them out and interfere with the adult's and eggs' growth.
• If the females drop the eggs or die after transfer, alter
your main tank instead to take care of the young there:
•Remove any fish from the main tank. Since you won't be
using your breeding tank after all, you can move them
there, altering the plant composition if necessary to suit
the species.
•Turn off or cover the filter.
•If your filter has a water intake pipe, it will suck in and
kill the young shrimp.
•Cover the intake with a sponge or piece of nylon
stocking, or turn it off and clean the water manually by
replacing 10% of it every day until the young are grown.
•Accept that some young shrimp will be eaten by the
adults. You can reduce the chance of this happening by
using a spacious tank, but it will be difficult to avoid.
Troubleshooting
26. Keep watching if the young
shrimp won't eat.
•The floating larvae may not eat much directly
after hatching.
•If they are still ignoring their food the next day,
you should try a different food immediately, as
they can starve quickly.
27. If all the shrimp die after putting them in
the tank, use different water or introduce
the shrimp more slowly.
•You may need to use tap water treated with a
dechlorinator, or even bottled water.
•Do not use rainwater or local river water unless
ghost shrimp live in the river you took it from.
•You should never pour the bag of water with
the shrimp directly into the tank.
•See Caring for Adult Shrimp for instructions on
introducing your shrimp.
•You may also want to purchase an aquarium
test kit to test the characteristics of your water.
See the Tips section below for the correct pH,
dH, and chemical levels for ghost shrimp.
