This document describes the different types of fishing crafts used in Chairman Ghat, Noakhali, Bangladesh. It outlines both mechanized boats like trawlers, fishing boats, and chandi boats as well as non-mechanized boats like dingi boats and taba boats. For each major craft, details are provided on its dimensions, construction materials, carrying capacity, crew size, engine type, fishing gear used, operating costs, catch capacity, and other specifications. In total, over 15 different local fishing crafts are defined in the document.
Fishing Gear any form of equipment, implement, tool or mechanical device used to catch, collect or harvest fish. Fishermen in many parts of Bangladesh catch fish with their hands. In rural areas, in seasonal waters or beels, during winter, people can be usually seen fishing with different traditional gears while some even do so without any gear
Present status of Fish Hatchery in BangladeshDegonto Islam
In the past decades the rivers of Bangladesh were the mentor natural source of carp seed production. Due to the destruction of natural habitats and also increase demand the natural available of carp seed has largely declined and the aquaculture venture and gradually replaced by the hatchery produced fry since early 80’s when artificial fish breeding technique and low cost hatchery design have been successful adapted in Bangladesh.
CAGE CULTURE OF FISH THEIR TREND,STATUS AND PRODUCTION Ashish sahu
Cage culture is an aquaculture production system where fish are held in Cage. Cage culture of fish utilizes existing water resources but encloses the fish in a cage which allows water to pass freely through the enclosures and the surrounding water body. Cages are used to culture several types of shell fish and finfish species in fresh, brackish and marine waters. Cages in freshwaters are used for food fish culture and for fry to fingerling rearing.
In 1950s modern cage culture began with the initiation of production of synthetic materials for cage construction. Fish production in cages became highly popular among the small or limited resource farmers who are looking for alternatives to traditional agricultural crops. The mesh size of the cage is kept smaller than the fish body. In India cage culture have been attempted first for Air breathing fish. Cage mesh netting made from synthetic material that can resist decomposition in water for a long period of time. Cage are used to culture several type of shell fish and fin fishes in fresh , brackish and marine water. Cage in fresh water are used for food fish culture and for fry to fingerling rearing. Cages are generally small, ranging in freshwater reservoirs from 1 square meter (m2) to 500 m2.
Definition –
Cage culture is a system in which the cultured Fish 0r animal are enclosed from all side allowing water to pass freely through the enclosures and the surrounding water body.
HISTORY-
Cage culture seem to have developed around 200 year ago in Cambodia where fisherman used to keep clarias spp. And some other fishes in bamboo made cage. Cage culture is traditional in part of Indonesia also attempted for the first time in air breathing fishes in swamp for raising major carp in running water in the river, Yamuna and Ganga at Allahabad and for raising Common carp , Catla , Silver carp, Rohu , Snakehead and Tilapia in still water body of Karnataka. In India sea cage start in 2007 for culture sea bass at Vishakhapatnam by CMFRI. anchored in streams which are practically open sewers. Common carp , where cage are in the southern USA. Around 80 species are being culture in cage. In India cage culture was initially culture in bamboo cage is practice in west java, since early 1940. Modern cage culture in open water bodies probably originated in Japan in early 1950. According to FAO cage culture is being practiced in more than 62 countries and has a become high tech business in developed countries such as floating and submerged cage culture of Salmonids in Norway, Canada and Scotland, Tuna and Yellowtails in Japan , Chinese carp in China, and catfish.

Blue Economy means sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean environment health. More specifically, it basically refers to any economic activity in the marine sector, whether sustainable or not”.In Bangladesh , Coastal and Marine based aquaculture has been developed day by day .There are many prawn and shrimp farm in Bangladesh among the different districts.These farm play a dominant role for rising blue economic development of Bangladesh .Besides sea weed is also a prominent aquaculture in Bangladesh .There are about 133 species of sea weeds that commercially produce in different kinds of farm in Bangladesh .Although there has so many bar to management theses types of farm ,but day by day the efficiency of producing these product are increasing very rapidly. A very great role has kept by the marine and coastal aquaculture for developing blue economy of Bangladesh
Any aquatic invertebrate animals having a cutaneous or calcareous shell surrounding there body and belonging to the phylum Mollusca, the class Crustacea (phylum Arthropoda), or phylum Echinodermata is known as shellfish. The term is often used for the edible species of the groups, especially those that are fished or raised commercially. The most commercially important shellfish are:
• Mollusk: Oysters, mussels, scallops and clams
• Crustacean: Shrimp, prawn, lobster, crab and crayfish
• Echinoderm: sea urchins and sea cucumbers
Shellfish hatchery is a place where shellfish seeds are produced in a controlled way. Hatchery management is a branch of science which deals with the activities including from collection of brood shellfish to seed production. Culturing of shellfish has occurred since ancient times. Although controlled rearing of young shell has long existed, hatchery production is a more recent advancement. Producing seed under controlled conditions in a hatchery will disconnect its production from environmental factors and provide a reliable supply of seed. Oysters, mussels and mud crabs are the most important groups of shellfish after shrimp and prawn. These are popular among the western countries and becoming more popular all over the world. So hatchery management of oyster, mussel and crab is crucial.
All the freshwater prawns that have been cultured so far belong to the genus Macrobrachium , Bate 1868, the largest genus of the family Palaemonidae. About 200 species have been described, almost all of which live in freshwater at least for part of their life.
The giant river prawn, Macrobrachium rosenbergii , was one of the first species to become scientifically known , the first recognizable illustration appearing in 1705. The nomenclature of freshwater prawns, both on a generic and a species level has had quite a muddled history. In the past, generic names have included Cancer (Astacus) and Palaemon. Previous names of M. rosenbergii have included Palaemon carcinus, P. dacqueti and P. rosenbergii ( De Man 1879) became universally accepted.

Coastal aquaculture is having an adverse impact on the environment due to intensive shrimp culture. several other factors are also getting affected due to intensive coastal aquaculture.
Fishing is integral to Bangladesh's culture, economy, and food security. Bangladesh has diverse fishing crafts and gears for different regions and fishing needs. Emphasis on responsible fishing practices and sustainability. Growing emphasis on adopting sustainable fishing practices in the Bay of Bengal, including the use of eco-friendly gear and gear modifications to minimize the impact on the marine environment. This includes the promotion of responsible fishing practices, such as seasonal closures, size limits, and catch-and-release policies, to ensure the long-term viability of fish stocks.
Introduction of new fishing gear holds the potential for improving fishing efficiency and sustainability, it must be accompanied by effective fisheries management and regulations to prevent overexploitation and protect the marine ecosystem in the Bay of Bengal.

The positive fact is that the fishermen in those villages are intent to change their present state. The urge for a positive change and willingness to offer personal contributions for such a change is visible among both men and women. The basic need is to facilitate their journey towards this change, with proper direction and guidance.

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.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

25. IMPORTANCE OF FISHING CRAFTS :
Fishing crafts play a vital role to capture or harvest fish from open water body.
Different types of fishing crafts are used on basis of different water depth and
different fish species. The importance of fishing crafts are as follows :
Mainly open water fishes are caught by fishing crafts.
There is less risk when using fishing crafts.
A large amount of fish can be caught by fishing crafts.
Fishing crafts are used to reach the fishing grounds and to catch fish from there.
Fishing crafts can be operated for several years.
Large fishing crafts are used when fishermen are going to deep sea for a long
period.
Fisherman are largely dependent on the fishing crafts for their livelihood.
26. LIMITATIONS :
Besides some importance of fishing crafts there are also some limitations. The limitations
are as follows :
Net should not be repaired after each trip.
Unskilled persons are operating fishing crafts into the deep sea.
Modern technologies are not added into the fishing crafts.
It is not possible to operate fishing crafts in deep sea during unfavourable weather
condition because they do not get any signal about bad weather condition..
Sometimes large fishing crafts are attacked by the sea – robbers in deep sea that causes
a great loss of fishermen.
Whenever the fishing crafts enter into the Sundarban area,the crafts are attacked by
robbers.
They hostage the fishermen if they can’t fulfil their demanding money.
Sometimes fishermen are killed by robbers.
The fishermen have to pay a fixed amount around 1000 for every six months in the fish
landing centre at Chairman Ghat for boarding their fishing crafts.
The collector take 10 tk/100 fish which is very despondency for them.
27. Possible Remedies:
Net should be repaired after each trip.
Skilled and educated persons are needed for operating fishing crafts into the
deep sea.
Modern technologies should be added into the fishing crafts.
Wireless should be introduced in the every fishing crafts.
Coast guard activities should be increased in the deep sea.
Collecting money from the fishing crafts anf fishermen should be reduced.
Brokers activities and collecting money from root level fishermen should be
reduced.
28. CONCLUSION
Fishing crafts are normally used to conduct fishing activities.
In Bangladesh mechanized fishing is hence forth not so popular.
Traditional fishing instruments are mostly used all over its country fisherman. But
the scattered document of fishing gears and crafts should be gathered.
Therefore, it is possible to comparison the use of fishing crafts and gears among
different can be done. Such way, we can have concept about the variety of
fishing crafts in Bangladesh.
