Setting an aquarium is an important steps to maintaining healthy ornamental fishes. It gives mind relaxation and peaceful. It is a hobby and reduces the stress also
The transfer of fish seed from the hatchery or place of collection to the rearing pond is called transport of fish seed. The seed fish include fry and fingerlings.
Fertilized fish eggs are known as Fish seeds. In simple words, they are the baby fishes used for seeding new Ponds in fisheries. Fish seed transportation is a process by which transfer of fish seed from the hatchery or place of collection to the rearing ponds.
Modern developments in transport technology are from two levels; one is from an understanding of internal physiological mechanisms of the fish and the optimal requirements, ensuring maximum survival of fish under transport and the other is from a study of the environmental parameters of the medium in which fish are transported. Under anaesthesia fish can be transported without water even, provided the skin and gills are kept moist under low temperature. The cryopreservation of fish sperm for use at any convenient time can be referred to here, though this would concern seed production more directly than live seed transport.
Fish culture is classified based on the number of fish species as monoculture and polyculture. This is the culture of single species of fish in a pond or tank. The culture of trout, tilapia, catfish , carps are typical examples of monoculture.
A fishing gear is the tool with which aquatic resources are captured, whereas the fishing method is how the gear is used. Gear also includes harvesting organisms.

Introduction:
Life table:
Life table is a comprehensive method of describing mortality, survival and other vital events in a population.
It is composed of several sets of values showing how a group of infants who are under unchanging conditions would gradually die.
It provides concise measures of longevity of that population.
Separate tables are prepared for males and females after each decennium census.
It is also called as the “Biometer” of the population by William Farr.
Vital statistics, the most important branch of statistics, deals with the mankind in aggregate.
It provides a description of the vital events occurring in given communities.
By vital events, we mean birth, death, sickness, marriage, divorce, fertility, etc.
It deals with people rather than with things.
Vital statistics are of much importance for the people and nation.
Vermitechnology means rearing of earthworms. earthworm is friend of farmer. earthworm is doing a great job and also produced a good organic manure is called vermicompost. vermicompost is a biofertilzer. which is enhancing soil qualities. This is explained earthworm biology, importance and preparation of vermicompost, vermiwash, panchgavya and their importance.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

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.
Palestine last event orientationfvgnh .pptxRaedMohamed3
An EFL lesson about the current events in Palestine. It is intended to be for intermediate students who wish to increase their listening skills through a short lesson in power point.
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.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2. What is an aquarium?????
•A tank or pool or bowl filled with water for
keeping live fish and underwater animals.
•An aquarium is a specially designed
device that acts as an artificial habitat for
water-dwelling animals.
3. Ornamental fish culture
• The culture of ornamental fishes is called as
aquariculture.
• Ornamental fish culture is the culture of
attractive, colourful fishes of various
characteristics, which are reared in a confined
aquatic system.
• Farmers and hobbyists mainly grow it.
• Ornamental fishes are also known as living
jewels.
4. AQUARIUM SET-UP
• Proper site selection (convenient water source, electricity, water
drains, etc.)
• Need GFCI - Ground Fault Circuit Interupter electrical outlets
• Strong supports and tank cushion
• Add water, then substrate and filter
• Aeration and heater
• Accessories (covers and lights)
5. Plants of the aquarium
•Rooted plants
a.) Vallisneria b.) Sagittaria
•Cuttings
a.) Fanwort b.) Hygrophila c.) Limnophila
• Floating plants
a.) Lemna b.) Riccia c.) Salvinia
7. The place and the stand
• Select the place where the temperature is the most stable
during the whole year.
• Another aspect is the aquarium stand.
• Usually a marine aquarium is very heavy because of the
amount of the water.
• The stand has to be strong.
8. Feeding
• The general rule is to feed small amounts frequently.
• Balanced food which consists of proteins, fat,
vitamins, minerals and carbohydrates.
• Most aquarium fish are fed on industrial food, which
has the form of flakes or granules.
•But you should feed them with natural food also.
9. • Natural food: It covers plants, protozoa,
gnathostoma, coelenterates, larvae of mosquitoes
and crustacean , shrimps, flies, coelenterates etc.
• Homemade food: minced meat, leafy vegetables,
lightly boiled and minced.
• Fish shouldn’t be fed on the same diet for long
periods.
11. 1. Temperature
• Temperature stress is one of the leading killers
of aquarium animals.
• Ideal range for a freshwater tank = 77 to 83F.
• Ideal range for a saltwater tank= 76 to 82F.
• At the Summer you need a chiller and during the
Winter you need a heater.
12. 2.Lighting
• If aquarium doesn't get sunlight then artificial
lights are used.
• If you use normal wolfram bulbs, the water
could overheat.
• The light should be in the form of long
fluorescent tube.
13. 3. Salinity
• Salinity is a measure of the total amount of dissolved
salts in seawater.
•Measured in parts per thousand (ppt).
• The average salinity of the ocean is around 34 to 37
ppt.
• Refractometers and hydrometers can be used to
estimate salinity in marine systems.
14. 4. pH
1. pH level in saltwater systems= 7.6 - 8.4.
•The normal trend for pH in a tank is more acidic.
•These acids come from several sources, the
primary ones being:
(1) excess carbon dioxide (CO2) from respiration
(2) nitric acid from biological filtration
(nitrification)
(3) organic acids from metabolic wastes.
15. 2.The optimum pH for a freshwater community tank
•pH value between 6.5 to 8.0 .
•In checking the pH of the local supply water, either let
a cup of tap water stand for a day or two or simply
check the aquarium water itself a few days after
setup.
•It is still valuable to check the pH periodically!
17. • The typical aquarium includes-
1. Filtration system
2. Artificial lighting system
3. Heater or chiller.
18. WATER FILTRATION
• Mechanical – passing water through materials that remove
suspended solids
• Biological – use of bacteria and other living organisms to convert
harmful substances to less harmful forms
• Chemical – use of chemical substances to purify water
19. 1. Filtration system
• Purpose- To clean the water of debris and suspended
particles, remove ammonia and nitrites and aerate the
water.
• Working- Most aquarium filters are divided into three
sections: Biological, Mechanical and Chemical.
20. Filtration system in a typical aquarium (1) intake,
(2) mechanical filtration, (3) chemical filtration,
(4) biological filtration medium, (5) outflow to tank
21. 1.Biological
• An aquarium filter is a breeding ground for two main
types of bacteria.
• The first type of bacteria breaks down the potentially
very poisonous ammonia that fish produce into less
harmful nitrites, and then a
• second type of bacteria breaks down the nitrites into
even less harmful nitrates.
22. • Uses bacteria to convert ammonia to nitrite and then to nitrate
• Crawfish and snails help keep tank clean
23. 2. Mechanical
•Removes large suspended particles of debris
from the water.
3. Chemical
•The purpose of this is to remove medications and heavy
metal traces from the water.
•Some aquarists use air pumps or water pumps to increase
water circulation and supply adequate gas exchange at the
water surface.
24. • Chemicals include ozone, ultraviolet light, activated charcoal, and
special chemicals
25. 2.Lightning
• Tank illumination describes any kind of light that is used
to brighten an aquarium.
• Since improper lighting causes fish stress, poor growth,
and impeded health, buying the right kind should be
considered.
• The main purpose of this is to replicate the conditions
of their natural environment.
26. • There are different fixtures designed for every type
of habitat -
1. bulbs,
2. fluorescent tubes,
3. metal halide lamps, and others.
• To beautify the look of your tank and increase the
growth and health of your creatures, it is best that you
choose the perfect and sufficient lighting technology
for your aquarium.
27. 3. A Heater or Chiller
• Aquarium heaters combine a heating element with a
thermostat, allowing the aquarist to regulate water
temperature at a level above that of the surrounding air.
• Whereas coolers and chillers (refrigeration devices) are for
use anywhere, such as cold water aquaria, that the ambient
room temperature is above the desired tank temperature.
• Thermometers used include-
1. glass alcohol thermometers,
2. adhesive external plastic strip thermometers,
3. battery-powered LCD thermometers.
29. 1) You must have sufficient light.
2) Check your plants regularly to ensure roots
don't come loose.
3) Don't overcrowd the aquarium.
4) Try to emulate an environment close to the
plants’ and fishes’ original environment.
5) Beware of introducing a diseased fish into
your freshwater aquarium.
6) Purchase your aquarium fishes and other
components required from a reputable dealer.
30. Benefits of an Aquarium
•Sit back and relax.
•Reduces stress and lowers blood pressure.
•Reduces the experience of pain.
•Alzheimer's and aquariums……..
31. SPECIES SELECTION FACTORS
• Temperature – tropical versus temperate
• Salinity – freshwater, brackish, or saltwater
• Reproduction – livebearers versus egg-layers
• Size – size of fish needs to match tank
• Feeding habits – carnivores, herbivores, or omnivores
