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.
Rotifers are popularly called as wheel animalcules. They are an important group of live food organisms for use in aqua hatcheries. Brachionus, which is the most known form of all rotifers, serve as an ideal starter diet for early larval stages of many fish and prawn species in marine as well as freshwater. Species of the genus Brachionus (Brachionidae: Rotifera) are well represented in different water bodies worldwide (Pejler, 1977). Depending on the mouth size of the cultured organisms, small (50 to 110 micron length) or large (100 to 200 micron length) rotifers are used. There are about 2,500 species of rotifers have been known from global freshwater, brackish water, and seawater. B. plicatilis is the species used most commonly to feed fish larvae in hatcheries around the world. It is a euryhaline species, small and slow swimming, with good nutritional value. It is well suited to mass culture because it is prolific and tolerates a wide variety of environmental conditions. The rotifer, B. plicatilis and B. rotundiformis, have been indispensable as a live food for mass larval rearing of many aquatic organisms (Maruyama et al., 1997). By way of significant developments in larval rearing technology of fishes, demand for the rotifer is further increasing.

Whale Shark The largest of all sharks and the largest living fish, the whale shark is one of the most dramatic views of the ocean. Its large size, distinctive patterns and its enormous mouth make it instantly recognizable and can be commonly seen wandering near the surface in tropical and subtropical waters around the world. Their diet is based mainly on plankton, but also regularly feed on small schooling fish and squid. Unlike basking sharks, which simply filter vast amounts of water as they swim, whale sharks actively suck their prey before filtering efficiently and are sometimes seen in groups, feeding on high concentrations of food. Regularly appear in the same places at specific times of the year, probably to capitalize on plankton blooms and events such as coral spawning.
Answering a question on Fish and Shell Fish Biology course for 2nd year B.Sc. student at Department of Fisheries, University of Chittagong, Chattogram 4331, Bangladesh. Submission date: 01st August, 2018.
Fish are all members of the phylum Chordata, sub-phylum Vertebrata. Fish are generally spindle-shaped, oval in section, and flattened either sideways or dorsal-ventrally. The skin is covered in protective scales, with some exceptions (lampreys, ocean sunfish). All fins have fins of some sort, all the size, number, and shape vary. Fish breathe through gills, and only a very few have actual lungs. Most fish have a special organ known as a swim bladder that prevents them from sinking, and, in some cases, aids in respiration. The common name "fish" refers to four different classes, depending on the person classifying them (there are numerous different ways to classify fish). Bony fish also have special adaptations that allow them to remain buoyant. A special organ called a swim bladder housed under the bony skeleton is a gas filled chamber that allows the bony fish to remain floating in the water. Some fish have a connection between this organ and the digestive tract to allow the extraction of oxygen. Another special adaptation is the operculum, a flap on each side of the fish that covers the chambers housing the gills. A bony fish is able to breathe without swimming simply by moving the operculum. Other hallmarks of these fish are paired fins, many teeth, dermal scales in the skin (in most species), and numerous vertebrae. Most bony fish are ray-finned fish, meaning that they have thin, flexible skeletal rays. Lobe-finned fish, the other type of bony fish, have muscular fins supported by bones. Only one species of lobe-finned fish, the coelacanth, still lives. However, it was the lobe-finned fish that made possible the colonization of land.
Seafood is any form of sea life regarded as food by humans, prominently including fish and shellfish. Shellfish include various species of molluscs, crustaceans, and echinoderms.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Silvercarp
The silver carp is a deep-bodied fish that is laterally
compressed. They are a very silvery in color when young
and when they get older they fade from a greenish color
on the back to silver on the belly. They have very tiny scales on their body but the head and
the opercles are scaleless. They have a large mouth without any teeth in the jaw, but they
have pharyngeal teeth. Its eyes are situated far forward on the midline of the body and are
slightly turned down.

7. Bighead carp
The bighead carp is a large, narrow fish with eyes that
project downward. Coloration of the body is dark gray,
fading to white toward the underside, and with dark
blotches on the sides. Its head has no scales, a large
mouth with no teeth, and a protruding lower jaw. Its
eyes are located far forward and low on its head. It is
very similar to the silver carp, and can be distinguished
by the dark coloration on its sides. The bighead carp can
be identified by a smooth keel between the anal and
pelvic fins that does not extend anterior of the base of
the pelvic fins.

8. Black carp is a blackish-brown fish with blackish-grey fins and an
elongated and laterally compressed body. One of the black carp’s
distinguishing characteristics is its pharyngeal teeth and this is
reflected in its scientific name. Black tipped scales give the
appearance of cross-hatching, Dorsal fin is short and pointed,
containing 7-8 rays, Dorsal fin is located above the pelvic fins, Anal
fin is located closer to the caudal fin than in the native minnow. The
black carp closely resembles the grass carp in appearance (body
shape and size; coloration; appearance, position, and shape of fins;
position and size of eyes), but may be most easily distinguished by
differences in the formation of the pharyngeal teeth: they possess
deep parallel grooves on the Grass carp and appear molar-likethey
on the Black carp.
OTHER COMMON SPIECIES OFPAKISTAN
Tilapia
Tilapia is the common name for nearly a hundred species of cichlid fish from
the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine and tilapiine tribes (form
erly all were in Tilapiini), with the economically most important species placed in Coptodonini and
Oreochromini.
Characteristics
Tilapia typically have laterally compressed, deep bodies. Like other cichlids, their
lower pharyngeal bones are fused into a single tooth-bearing structure. A complex set of muscles
allows the upper and lower pharyngeal bones to be used as a second set of jaws for processing food
(cf. morays), allowing a division of labor between the "true jaws" (mandibles) and the "pharyngeal
jaws". This means they are efficient feeders that can capture and process a wide variety of food
items.[11]
Their mouths are protrusible, usually bordered with wide and often swollen lips. The jaws
have conical teeth. Typically, tilapia have a long dorsal fin, and a lateral line which often breaks
towards the end of the dorsal fin, and starts again two or three rows of scales below. Some Nile
tilapia can grow as long as 2.0 ft.
Other than their temperature sensitivity, tilapia exist in or can adapt to a very wide
range of conditions. An extreme example is the Salton Sea, where tilapia introduced when the water
was merely brackish now live in salt concentrations so high that other marine fish cannot survive.
Tilapia are also known to be a mouth-brooding species, which means they carry the fertilized eggs
and young fish in their mouths for several days after the yolk sac is absorbed.

10. Salmon
Salmon is the common name for several species of ray-finned fish in the family Salmonidae. Other
fish in the same family include trout, char, grayling and whitefish. Salmon are native to tributaries of
the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus). Many species of salmon
have been introduced into non-native environments such as the Great Lakes of North America
and Patagonia in South America. Salmon are intensively farmed in many parts of the world.
Typically, salmon are anadromous: they hatch in fresh water, migrate to the ocean, then return to
fresh water to reproduce. However, populations of several species are restricted to fresh water
through their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn.
Tracking studies have shown this to be mostly true. A portion of a returning salmon run may stray
and spawn in different freshwater systems; the percent of straying depends on the species of
salmon. Homing behavior has been shown to depend on olfactory memory. Salmon date back to
the Neogene.

12. Trout
The rainbow trout (Oncorhynchus mykiss) is a trout and species of salmonid native to cold-
water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called
"steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout (O. m.
irideus) or Columbia River redband trout (O. m. gairdneri) that usually returns to fresh water
to spawn after living two to three years in the ocean. Freshwater forms that have
been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead.
Adult freshwater stream rainbow trout average between 1 and 5 lb (0.5 and 2.3 kg), while lake-
dwelling and anadromous forms may reach 20 lb (9 kg). Coloration varies widely based
on subspecies, forms and habitat. Adult fish are distinguished by a broad reddish stripe along
the lateral line, from gills to the tail, which is most vivid in breeding males
