Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. The pressure of the fluid increases with depth, creating a force that pushes up on any submerged object. The buoyant force can be measured by subtracting the weight of an object in water from its weight in air, and is equal to the weight of the fluid it displaces.

Bony fish powerpoint
The document summarizes key characteristics of bony fishes. It describes that bony fishes have over 27,000 species, an endoskeleton of true bone, and are found in all marine habitats. It then outlines some of the major types of bony fishes including lobe-finned fish and ray-finned fish. Mobility, buoyancy, gas exchange, senses, reproduction and protection mechanisms are also summarized.
Reproductive strategies in fishes
This document summarizes different reproductive strategies in fishes. It discusses that most fishes are oviparous and lay eggs externally. For marine fishes, the majority have pelagic eggs that float, while demersal eggs that sink are more common in freshwater. Some fishes are ovoviviparous or viviparous with internal fertilization. Different forms of parental care among fishes are also outlined, including by the male, female or both parents. Alternative reproductive strategies discussed include hermaphroditism, parthenogenesis, and natural polyploids and hybrids.
Life cycle of prawn
The document describes the life cycle and development of the typical penaeid prawn Penaeus monodon. It discusses that wild gravid females spawn in open sea, and the planktonic larval stages last about 2 weeks until postlarvae are found in coastal and estuarine areas. The postlarvae then develop into juveniles and adults in estuaries before returning to sea to spawn. It outlines the 5 stages of ovarian development and spawning, where a female can produce 500,000-1,000,000 eggs per spawn. The document then details the characteristics and duration of the nauplius, protozoea, mysis, and postlarval stages in the praw
Hybridization in fishes
Hybridization is the breeding between two different species or genera. This document discusses different types of hybridization in fish, including interspecific (between different species of the same genus), intergeneric (between different genera), and natural vs artificial hybridization. Interspecific hybridization in Indian major carp led to hybrids that exhibited faster growth than parents. Over 30 intergeneric hybrids were produced between catla, labeo, and cirrhinus genera. Natural hybridization is more common in freshwater fish due to overlapping habitats and spawning grounds. Factors like external fertilization and unchanged behavior can lead to natural hybridization. Artificial hybridization aims to combine desirable traits and is done by various methods like cohabitation and hormone
Estuarine fisheries n.a.k.
This document discusses estuaries and estuarine fisheries in India. It defines an estuary and notes that India has over 55 estuaries along its eastern and western coasts, totaling approximately 30,000 square kilometers. Several major river systems like the Ganges, Mahanadi, Godavari and Krishna form highly productive estuarine ecosystems. The document examines the fish production and ecology of estuaries like the Hooghly, Krishna, Godavari, Mahanadi, Chilka, Pulicat Lake, and Kerala backwaters. It provides details on fish catches, species diversity, and threats like overfishing in several of India's important estuarine systems.
fouling and boring
This document discusses marine bio-deterioration caused by fouling and boring organisms. It defines bio-deterioration as undesirable changes to materials caused by living organisms. Fouling organisms like algae and animals settle on surfaces like wood and steel, while boring organisms like mollusks and crustaceans bore into and damage materials like wood. This causes economic losses for fishing boats and aquaculture infrastructure. The document covers the types and impacts of fouling and boring, as well as control methods like cleaning, coatings and preservatives. It explains that fouling occurs as organisms find surfaces to attach to, while boring provides shelter, food or aids in digestion for some organisms.
Swim bladder
The document discusses the swim bladder, or air bladder, of fish. It is an internal gas-filled organ that contributes to a fish's ability to control buoyancy. There are two types - physostomous, which is directly connected to the digestive tract, and physoclistous, which is not connected. The basic structure includes a sac-like shape with two layers, an epidermis and endodermis. The swim bladder varies in shape and size between fish species and allows fish to rise and sink in water by increasing or decreasing the volume of gas inside without changing mass. Its key functions are to act as a hydrostatic organ, adjustable float, aid in respiration, produce sound, and maintain the fish's
Lecture 3. farming methods
This document discusses different farming methods for aquaculture, including cage culture, pen culture, and sewage-fed culture. Cage culture involves rearing fish in an enclosed water volume using net cages suspended from floating frames. Pen culture uses barriers like nets or fences to partition off areas of water bodies for fish culture. Sewage-fed culture utilizes treated sewage as fertilizer to promote plankton growth and increase fish production. Primary and secondary treatment methods are used to process sewage before use in aquaculture.

It then classifies eggs into four types based on amount of yolk, yolk distribution, development potency, and presence or absence of a shell. The main egg types include microlecithal, mesolecithal, macrolecithal eggs and mosaic vs. regulative development.
Electric organs in fishes 1
Electric organs are found in about 250 species of fish and are composed of electroplates, which are stacks of electrocytes that discharge electricity. The organs vary in voltage output between species from 4-550 volts and serve functions like catching prey, defense, communication, and territory maintenance. Electric organs are thought to have evolved from muscle tissue, with different fish lineages co-opting different muscle groups for electrocyte differentiation during development.
MIGRATION OF FISHES
1) Fish migration involves the movement of fish from one area to another, usually for feeding or breeding purposes. Several species migrate long distances for spawning and feeding, including cod, herring, salmon, eel, and tuna.
2) There are different types of migration including alimentory (for food/water), gametic (for reproduction), climatic (for suitable climate), and osmoregulatory (for osmoregulation). Fish can migrate through drifting with water currents, random locomotory movement, or orientation swimming in a particular direction.
3) Migration patterns vary between species and include diadromous (between fresh and salt water), potamodromous (within fresh
DEVELOPMENT OF FROG.pptx
1. The document summarizes the development of frog sperm, eggs, fertilization, and early embryonic development. It describes how the male and female frogs mate and the structure of their sperm and eggs.
2. During fertilization, one sperm fuses with the egg to form a zygote. This triggers formation of a fertilization membrane and grey crescent on the egg surface, establishing the embryo's polarity.
3. Cleavage and blastulation occur, forming a blastula. Gastrulation then transforms the blastula into a three-layered embryo through invagination, involution, and epiboly.
Migration in fishes
This document summarizes fish migration. It defines fish migration as seasonal movement that implies returning to the starting point. It discusses different types of migratory fish species and patterns of migration including diadromous, potamodromous, and oceanodromous. The causes of migration are to avoid unfavorable conditions and exploit food sources. Physical, chemical, and biological factors influence migration. Advantages include access to more food, breeding places, and distribution while avoiding competition. Conservation of migratory fish is important for sustaining fisheries and coastal communities.

CAGE CULTURE
Cage culture involves raising fish in mesh boxes placed in bodies of water. It originated in Cambodia about 200 years ago when cages were used to transport live fish to market. Cages are constructed with frames made of wood, plastic or steel, with floats to keep them buoyant and weights to anchor them. They come in various shapes and sizes, usually square or rectangular, and are 20-60 cubic meters. Cages are either fixed in flowing water, floating in lakes/rivers/offshore, or submerged and movable in areas prone to cyclones. Fish are fed through natural water movement and supplemental feeding of rice bran, fish meal and soybean cake. Fish production ranges from 3,000-25,000 kg
Ornamental fish culture
Ornamental fish culture provides opportunities for entrepreneurship and income generation. It requires a minimum of 500 sq ft of land and access to fresh water and electricity. Selection of quality broodstock is important, as different species prefer different water parameters for breeding. Beginners should start with livebearers like guppies and later move to egg-layers, focusing on one species at a time. CIFA has developed technologies for breeding 16 indigenous ornamental fish species and commercializing an endangered species. It conducts national training programs and facilitates entrepreneurs with business plans and information on government subsidies.

Shell fishery refers to the study, commercial exploitation, and industry of catching, processing, and selling shellfish. Shellfish are distinguished from finfish by their hard outer shells and lack of backbones. There are two main classifications of shellfish - mollusks, which have soft bodies and shells, and crustaceans, which have segmented shells and jointed legs. Common shellfish include mollusks like oysters, clams, and scallops, and crustaceans like shrimp, lobster, and crabs. Shellfish are harvested using various methods and are an important global aquaculture industry.The Origin of Vertebrates
This document summarizes the evolution of vertebrates from their earliest ancestors to modern forms. It describes the key traits that unite each major group, from non-vertebrate chordates like tunicates and lancelets, to the earliest jawless fish like hagfish and lampreys, to jawed fish groups like sharks and bony fish. It outlines the major transitions from marine to freshwater habitats and the evolutionary innovations in skeletal and sensory systems that occurred in the main vertebrate lineages over 500 million years.
fish RESPIRATION.ppt
Metabolism: the word to describe the totality of energy consuming, manipulative and storage chemical reactions by organisms.
Second law of thermodynamics dictates that all processes increase amount of entropy in the universe. Thus, a highly ordered entity like a fish can only exist with a constant input of energy that allows it to remain ordered.
Therefore, initial requirement of fish survival is to obtain sufficient energy to offset this universal randomization process by: maintaining ion gradients and renewing proteins (Chabot et al., 2016). “Respiration is nothing but a slow combustion of carbon and hydrogen, similar in all respects to that of a lamp or a lighted candle, and from this point of view, animals which breathe are really combustible substances burning and consuming themselves” (Lavoisier & Laplace, 1783).
All animals must supply their cells with oxygen and rid their body of carbon dioxide.
The physiological process by which an animal exchanges oxygen and carbon dioxide with its environment.Most fish have external gills that are ventilated by a unidirectional flow of water, by pumping or swimming.
Fine sieve structure of gills very efficiently extracts O2 from water.
Efficient O2 uptake is vital to fish because of its low water solubility.
Solubility decreases with increased temperature & salinity!
Also, metabolic rate (demand for O2 ) increases as temperature rises.
‘Branchia’ in greek = ‘gills’
In boney fish (Teleosts):
Gills lie in a branchial cavity covered by the operculum:
Usually two sets of four holobranchs.
Each holobranch consists of two hemibranchs (‘half gill’):
Anterior and posterior
Hemibranchs consist of a row of long filaments (primary lamellae) with semilunar folds (secondary lamellae).
Lamellae or filaments:
Connective tissue scaffold (epithelial cells) framing a vascular network providing blood flow primarily used for gas and ion exchange.Fish employ the countercurrent system to extract O2 from the water.
This system moves water flowing across the gills, in an opposite direction to the blood flow creating the maximum efficiency of gas exchange. Blood flow through lamellae is from posterior to anterior
(back to front).
Water flow over lamellae is from anterior to posterior
(front to back).
Counter-current allows for diffusion from high O2 in water to low O2 in blood across entire length of lamella.Gas gland is location of action in wall of swim bladder (rete mirabile “wonderful net” and surrounding tissues)
Need to pry O2 molecules from Hb molecules in gas gland
Need to accumulate enough O2 (>pO2) in solution in blood plasma to generate a diffusion gradient from distal end of rete mirabile into lumen of swim bladder
Change of pH in blood causes change in bond strength of Hb for O2
Bohr effect--decrease in affinity of Hb for O2 due to decreasing pH or increasing pCO2 affinity: strength of attraction of Hb for O2
Root effect--decrease in capacity of Hb for O2 due to decreasing pH or increasing pCO2
Seaweed farming status in world view B.pptx
Global seaweed production was 68.1 million tonnes in 2020, with China producing the vast majority at 35 million tonnes. Seaweed farming is an emerging industry in India, where traditional methods involve collecting spores from natural seaweed beds and cultivating sporelings on bamboo rafts. New pilot projects in Goa and Tamil Nadu are demonstrating seaweed's potential to support coastal communities and generate $8,800 - $31,000 annual income per family. With the global seaweed market projected to exceed $95 billion by 2027, India aims to increase domestic production to 1 million tonnes annually and enter the international market.
Seaweeds
The document provides information on seaweeds or macroalgae. It discusses their taxonomy, structure, ecology, common genera and uses. Seaweeds are a source of food, hydrocolloids like agar and carrageenan used in food production, and have applications in medicine, fertilizer, and other industrial uses. The Philippines cultivates various seaweed species like Eucheuma and Kappaphycus which are sources of carrageenan, an emulsifier used in food and other industries. Seaweed farming involves selecting a suitable pollution-free site and using culture methods like stakes, suspended ropes, or raft and spider web systems to grow the seaweeds.
Pre-stocking management of nursery pond for IMC
Pre stocking management is one of the important method of entire three tire fish farming system. Because, fish mortality is very high at the stage of spawn. The stocking density of nursery pond is 2 lacks/ha.
In Nursery pond fish nursed very well to prevent fish mortality.
Fish swim
Fish swim using undulations of their body and fins. They have a network of muscles that contract and relax to create waves that travel down the body and propel the fish forward. Fins provide control, thrust, lift, and drag. Forces acting on the fish include thrust from parts of the body pushing against water and lift and drag forces. Fish also generate lift using their swim bladder by inflating or deflating it with oxygen to control buoyancy. Forces resisting the fish's movement include frictional, pressure, and form drag.
Induced breeding in fishes
This document discusses induced breeding techniques for fish. It begins with an introduction and outline, then describes the history and need for induced breeding when fish do not naturally breed in captivity due to environmental or hormonal factors. It explains that induced breeding involves stimulating fish with pituitary extracts or hormones to breed. The document provides details on techniques for induced breeding, including collecting and preserving pituitary glands, preparing extracts, selecting and injecting brood fish, and stripping eggs and milt. It notes some advantages of induced breeding for fish culture and management.
Respiration in Fish
In aquatic animals such as fish respiration takes place through special respiratory organs called gills, however lung fish respiration takes place through lungs. Gills are present on both the sides of the head of fish. The gills are covered by gill covers also called operculum. When the fish open its mouth, water is drawn into the buccal cavity and passed through the gills. The gills contain special type of cells that absorb the oxygen present in water. The absorbed oxygen is then supplied to all the cells of body through blood. In the cells, oxygen is converted into carbon dioxide and returned back to gills through blood. Ultimately, the gills release the carbon dioxide in water passing through them.
Respiration in Fish
The gills of fish are very efficient; it is estimated gills can extract about 80% oxygen dissolved in water. In addition to the respiratory organs, the gills have an important role in maintaining the right balance of salts in the body.
FINS IN FISHES ZOOLOGY.pptx
The document describes the key fins found in fish, including their locations and functions. It discusses the pectoral fins, dorsal fins, pelvic fins, and caudal fins. The caudal fin is described as the most important for forward propulsion during swimming. Different types of caudal fins are also outlined, including protocercal, heterocercal, and homocercal fins.
Induced breeding in fishes
Induced breeding is a technique where organism is stimulated by particular hormone or other synthetic hormone or by providing condition, introduced to breed in captive condition.
ARCHIMEDES' PRINCIPLE
Archimedes was a Greek scientist who discovered the principle of buoyancy, now known as Archimedes' Principle, after noticing that he displaced water in a bath tub when he stepped inside. His work in geometry, mechanics, and understanding of levers helped the Greek army defeat the Romans. Archimedes' Principle states that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object. This principle is used in ship and submarine design and in instruments like lactometers and hydrometers that measure density. The formula for Archimedes' Principle relates the density of an object to the density of the fluid, allowing calculation of buoyant force without measuring volumes.

It explains that induced breeding involves stimulating fish with pituitary extracts or hormones to breed. The document provides details on techniques for induced breeding, including collecting and preserving pituitary glands, preparing extracts, selecting and injecting brood fish, and stripping eggs and milt. It notes some advantages of induced breeding for fish culture and management.
Respiration in Fish
In aquatic animals such as fish respiration takes place through special respiratory organs called gills, however lung fish respiration takes place through lungs. Gills are present on both the sides of the head of fish. The gills are covered by gill covers also called operculum. When the fish open its mouth, water is drawn into the buccal cavity and passed through the gills. The gills contain special type of cells that absorb the oxygen present in water. The absorbed oxygen is then supplied to all the cells of body through blood. In the cells, oxygen is converted into carbon dioxide and returned back to gills through blood. Ultimately, the gills release the carbon dioxide in water passing through them.
Respiration in Fish
The gills of fish are very efficient; it is estimated gills can extract about 80% oxygen dissolved in water. In addition to the respiratory organs, the gills have an important role in maintaining the right balance of salts in the body.
FINS IN FISHES ZOOLOGY.pptx
The document describes the key fins found in fish, including their locations and functions. It discusses the pectoral fins, dorsal fins, pelvic fins, and caudal fins.

ARCHIMEDES' PRINCIPLE
Archimedes was a Greek scientist who discovered the principle of buoyancy, now known as Archimedes' Principle, after noticing that he displaced water in a bath tub when he stepped inside. His work in geometry, mechanics, and understanding of levers helped the Greek army defeat the Romans. Archimedes' Principle states that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object. This principle is used in ship and submarine design and in instruments like lactometers and hydrometers that measure density. The formula for Archimedes' Principle relates the density of an object to the density of the fluid, allowing calculation of buoyant force without measuring volumes.

Ppt on energy and power resource made by mudit gupta class 9 th
Power resources can be categorized as conventional or non-conventional. Conventional resources that have long been in common use include firewood and fossil fuels like coal, petroleum, and natural gas. Non-conventional renewable resources that are unlimited include solar, wind, nuclear, geothermal, tidal, and bio gas energy. These alternative sources harness energy from the sun, wind, heat below the Earth's surface, water, and organic waste to generate electricity without the same environmental impacts as fossil fuels.

Biofuels Presentation
This document discusses the potential for microalgae to be used for biodiesel production. It notes that global efforts are underway to reduce carbon emissions and alternative fuel technologies are being explored. Microalgae can use photosynthesis to convert lipids into fatty acids suitable for biodiesel. Various growth conditions and processes are used to cultivate microalgae, including open pond systems. Research aims to optimize production through genetic manipulation and nutrient deprivation. Microalgae growth could also help treat wastewater. Further developing efficient harvesting methods is still needed to make biodiesel from microalgae economically feasible.
Buoyancy
The document discusses buoyancy and Archimedes' principle. It explains that whether an object sinks or floats depends on the relative densities of the object and the fluid it is placed in. Archimedes discovered that the buoyant force on an object equals the weight of the fluid it displaces. He proved that a crown was not pure gold by showing that its cumulative density was less than a pure gold sample when placed in water. His principle states that if an object's density is greater than the fluid's, it will sink, and if its density is less, it will float.
Fluid flows
The document discusses various terms used in fluid flows such as path lines, streak lines, streamlines and stream tubes. It also discusses different types of fluid flows including steady and unsteady, uniform and non-uniform, laminar and turbulent flows. The document then describes a Venturi meter and orifice meter, which are devices used to measure fluid flow rates based on Bernoulli's principle. A Venturi meter consists of a converging inlet, throat and diverging outlet, while an orifice meter uses a thin circular plate with a hole to restrict flow. Both devices are commonly used to measure flows in pipes and channels.
Buoyancy.ppt
Buoyancy and pressure in fluids are discussed. Objects experience an upward buoyant force when submerged in fluids due to higher pressure at deeper levels pushing up on the bottom of the object. Archimedes' principle states that the buoyant force equals the weight of fluid displaced by the object. The buoyant force can be calculated by subtracting the weight of the object in water from its weight in air.
Buoyancy & floatation
1) Buoyancy is the upward force exerted by a fluid that opposes the weight of an immersed object. This force is equal to the weight of the fluid displaced by the object and allows objects with lower density than the fluid to float.
2) The key factors that determine if an object will float or sink are the density of the object compared to the fluid density, the weight of fluid displaced versus the object's weight, and the object's shape.
3) Stability of floating objects depends on the location of the meta-center point, which is where the line of buoyancy force meets the axis when tilted. Stable equilibrium requires the meta-center to be above the center of gravity

The document outlines problems with petroleum dependence including economic costs, geopolitical issues, and environmental impacts. It then discusses various alternative fuels and vehicles including electric, hybrid, biofuels, natural gas, and hydrogen fuel cells. The lecture notes the complex challenges involved in transitioning away from near-exclusive reliance on oil for transportation.
Types of fluid flow best ppt
A fluid is a state of matter in which its molecules move freely and do not bear a constant relationship in space to other molecules.
In physics, fluid flow has all kinds of aspects: steady or unsteady, compressible or incompressible, viscous or non-viscous, and rotational or irrotational to name a few. Some of these characteristics reflect properties of the liquid itself, and others focus on how the fluid is moving.
Fluids are :-
Liquid : blood, i.v. infusions)
Gas : O2 , N2O)
Vapour (transition from liquid to gas) : N2O (under compression in cylinder), volatile inhalational agents (halothane, isoflurane, etc)
Sublimate (transition from solid to gas bypassing liquid state) : Dry ice (solid CO2), iodine
Alternative fuels and their uses
The document discusses the increasing reliance on fossil fuels for energy needs and the finite nature of these resources. It states that approximately 90% of energy requirements are met by fossil fuels like coal and petroleum, which are expected to deplete within the next 200-300 years and few decades respectively. To avoid future scarcity, the document emphasizes the need to develop alternative renewable energy sources like hydrogen, biodiesel, ethanol, and biomass, which are more environmentally friendly and sustainable than fossil fuels.
Final Year Project Presentation
The document compares the cost of designing a building using different structural systems, including a dual system without beams, building frame system with beams, and other options. It finds that the dual system without beams has the lowest total cost at $80 million, while the most expensive is the moment resisting system with beams at $120 million. Charts and tables show the cost breakdown by structural element and comparisons of total costs for each system.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

ppt on buoyancy
- 2. What is buoyancy ? • Buoyancy is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
- 3. Illustrations: • The bottom of the fish is deeper so there is more fore pushing up on it – a buoyancy
- 4. How to measure the buoyant force • Weight of object in air- weight of object in water =upward buoyant force. • The buoyant force is equal to the weight of the displaced water
