Fishing gear used without nets in Bangladesh include various types of traps, wounding gears like spears, and hook and line fishing techniques. Common traps discussed are Anta, Benta, Polo, Harol, Icha Chai and Kholoi which are made of split bamboo and wood. They are used to catch small fish species. Spears like Konch and Teta have bamboo handles with iron tips or hooks and are thrown or used to wound fish like Shol and Gozar. Hook and line techniques involve hand lines with or without wheels, and simple hand-held lines like Sip, Tana Barshi, Choto Barshi and Kecho Barshi to catch various fish species using earthworms
Various parameter have been used by different authors for classification of fishing gear and fish catching methods. According to Hardy (1947) - Hardy best his classification on fishing method like luring, snaring and attacking.According to Umali (1950)- Umali classified fishing gear of Philippines as non-textile device and textile device.According to Davis (1958) – Davis made an effort to classified gears of England without drawing definite line of demarcation.According to Dumont and Sundstrom (1961) – commercial fishing gears of united state where classified based on similarity of types.According to Andres Von Brandt (1972) – Von Brandt classified the fish catching methods of the world on the basis of how the fish are catch. The subgroups of Von Brandt 1972 classification are made on parameter like material construction and method of operation. International Standard Statistical Classification of Fishing Gear (ISSCFG-1980) has classified the fishing gear in accordance with the internationally recognized standard Von Brandt 1972 classification is the most popular one and is universally accept.Andres Von Brandt has classified is fish catching methods of the world in to 16 major groups based on how the fish are caught.
Traps are fishing devices into which fish or shellfish are enticed by bait or shelter spaces or enclosures where they are guided to enter, because of an obstacle placed in their normal migration path and from which their escape is made difficult by constriction, retarding valves or labyrinths.
Trap fishing is a passive fishing technique of ancient origin. There is extraordinary variety in their design, fabrication and operation.

Fishing gears are defined as tools used to capture marine/aquatic resources, whereas how the gear is used is the fishing method.
Fishing is the art of catching fish and other aquatic animals. Many years ago man started using various type of gear used for hunting the terrestrial animals and for fishing also. It is very difficult to say which started first, but some time it is opined that fishing is younger. Reason behind it is easy to catch animals in the land than in the water. In olden days fishing was not having much importance as there was no demand for fish. Earlier fishing was restricted to a particular community but it is not so now. In order to meet the increased demand, fishing is now carried out industrially. Fishing technology not only concerns fishing gear, fishing methods and vessels but also concern Biological and Environmental factors
Traditional fishing Craft of India by Ashish sahuAshish sahu
Fishing crafts are most essential for catching the fish in large scale in water bodies. A large variety of crafts (boats) have been designed for marine and inland fishing in India. The types of fishing crafts of India falls under two general categories. These are Non –mechanized and mechanized fishing crafts.
Based on the topographical variations and difference in habits and habitats of fishing, different types of crafts and gears are used in various inland water system of India. The simplest and most primitive types of craft used for fishing in inland water are the rafts and songas, operated in calm water. In the larger rivers and estuaries subject to strong current and tidal movement, sturdier plank boats are used.

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
Fishing gears
Dredges.
Gillnets and similar nets.
Hooks and lines.
Pots and traps.
Seines.
Surrounding nets and lift nets.
Trawls.
Data sources.
Fishing gears are commonly classified into two main categories: passive and active. This classification is based on the relative behavior of the target species and the fishing gear.
Almost any equipment or gear used in fishing can be called fishing tackle, examples being hooks, lines, baits/lures, rods, reels, floats, sinkers/feeders, nets, stringers/keepnets/live wells, spears, gaffs, traps, waders, and tackle boxes, as well as any wire, snaps, beads, spoons, blades, spinners, clevises and tools
Trawl nets and bottom seines possess an initial selectiveness owing to their particular design and mode of operation. A mesh size limitation would vary considerably in effect from one type of trawl net to another. It is important therefore to consider gear selectivity and performance before we begin to think of mesh sizes and their effect.
Take a herring vinge trawl for example and two other bottom other trawls like the granton trawl and the shrimp trawl. All use otter boards, all are on the sea bed throughout the duration of the tow and all have the same basic structure of wings, square, bellies, bag and cod end. But their performances differ as much as those of a racing car, a truck and a tractor. All three nets could be fishing in the same area, yet the vinge trawl might take only herring, the granton trawl only demersal fish and the shrimp trawl primarily shrimp or prawn. Mesh size has little to do with this species selection. It is a function of other aspects of gear performance - speed of tow, headline height, ground contact, flow of water through the body of the net, otter door spread, length of ground-cables, and so on. The vinge trawl would have the smallest mesh in the cod end, yet it would take no cod, haddock or shrimp. The shrimp or prawn trawl would have a smaller mesh than the granton trawl yet it would capture only a small proportion of the bigger fish the granton trawl would take. To imagine that in these cases the size of mesh controls the size of fish caught would be as simplistic as to think that the respective speeds of the racing car, truck and tractor were determined by the size of their wheels.
In contrast to the trawls designed to capture one species or group of species, there are the multi-species trawls or combination trawls which take a great variety of fish. The North Sea prawn and fish trawl is a combination net designed to capture Nephrops norvegicus or Norway prawns, plus demersal fish like cod, haddock, skate, monks, plaice and lemon sole. Most bottom trawls in the tropics and sub-tropics are multi-species trawls taking fish which vary greatly from each other in size and shape. There is no common selectivity factor and no common minimum size or length for the various species. For these fisheries, a mesh regulation is at best an inadequate means of reducing juvenile mortality. It can be aimed only at the smallest of the main commercial species.

Spearing, Harpooning and Shooting fish.pptxMurabiyaUdit
In very old age time there are not that much development in fishing technology. The fishing spear its simplest form and it is the fisherman’s most primitive gear. The range and capacity of humans to seize living fish by some means from a distance, is limited by the length of his arm. Harpoons are widely used in fisheries.
This gear has replaced the older spears in many instances and is used in large fishing, small scale fishing and in sport fishing

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.

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

Low energy requirement in operation
Excellent condition of the catch which are usually alive when caught
High market value of the catch
Traps can be made from locally available materials
Traps are relatively difficult to operate and haul during rough weather
High loss rate during operation
Ghost fishing by lost traps leading to unwanted fishing mortality
Advantage of traps
Disadvantage of traps
22. • Wounding fishing gears were made up of bamboo, wood shifts with forks or group of iron points.
These devices were used when large fishes float or drift on the surface water.
• This fishing devices (Spears) are used to catch fish by throwing or wounding fishes.
Wounding Gears
We have found two types of spears in Noakhali
1. Konch
2. Teta
23. Konch
Physical Structure
• Konch having more than 10 pieces of bamboo splits are firmly fixed in a bunch.
• The pointed ends of the bamboo splits are covered with sharp and pointed iron caps to increase the
efficiency.
24. Mode of operation
• The konch is thrown at the fish with great force so that the prongs pierce the fish. It is normally
operated by the fishermen from a or embankment.
• It was operated in shallow water to catch bottom and pelagic fishes. The sharp end of the prong
wounds the fish.
• During fishing, operator aims the target fish and throws the gear towards the fish..fisherman then
collects wounded fish.
Catch composition
• Fish caught by this gear are Shol (Channa striatus), Gozar (Channa marulius), Taki (Channa punctatus)
25. Teta
Physical structure
• Teta is a wounding gear made of a long bamboo handle about 2 to 4 m long and several iron hooks with
iron rod at the base.
• The length of iron rod is about 60 to 65 cm with hooks at the apex.
• The iron rod with hooks is tightly tied with the bamboo handle by coconut thread or iron wire.
Operation
• Same as konch
Catch composition
• The fisherman throws the gear to target species like Boal (Wallago attu), Shoal (Channa striatus), Taki
(Channa punctatus), Bele (Glossogobius giuris) and others fish species.

Fishing is not possible in deep area
Fish are injured by spear so fish spoilage accelerated
Spear fishing is not profitable
• Easy to catch
• Operation of these gear is simple
• Spears can be made locally
Advantage of spear
Disadvantage of spear
30. Hooks
A fish hook or fishhook is a device for catching fish either by impaling them in the mouth or, more rarely,
by snagging the body of the fish. Fish hooks have been employed for centuries by anglers to catch fresh
and saltwater fish.
Local people are used different types of hooks that are varying with size and shape for catching
various types of fish such as Boal, Koi, Taki, Tengra, Rui, Katla etc
Types of hooks
a. J hook
b. Circal hook
31. J hook:
J-hooks are manufactured with the point of the hook parallel to the shank of the hook creating a J-shape.
Circle hooks:
Circle hooks are manufactured with the point of the hook turned perpendicularly to the shank forming a
circular shape.
32. Line Fishing
Fishing by means of hand or long lines with baited hooks is known as line fishing. A fishing line is a
cord used or made for angling.
Types of Line Fishing
There are various type of line fishing in Bangladesh but we only found two types of line fishing, these
are given bellow:
1. Hand line with wheel
2. Hand Line without wheel
33. Hand line with wheel
• This line is operated by wheel. When fish get stuck with the hook, the wheel is operated to coil the cord.
• The length of the cord may be 50-60 m.
• Catchable species are Labeo rohita, Catla catla, Cirrhinus mrigala, Labeo calbasu, etc.
34. Hand line without wheel
Sip (usually used in game fishing)
• The rod of local sip is made of still, hook are tied one end of the line.
• This type of line is used in game fishing.
• Main caughy species are Boal (Wallago attu), Kalibaus (Labeo
calbasu), Rui (Labeo rohita) and Mrigal (Cirrhinus migala) are the
main fish species caught by this gear.
• Market price of this device starts from 1800 to 3000 taka.
35. Sip or Barshi (usually used in rural area)
• Sip or barshi is a very simple barbed hook tied with one end of a line and the other end with a
bamboo stick.
• Earth warm and small prawn is used as bait.
• Main fish species caught by this type of gear are kalibaus (labeo calbasu), koi (anabas testudineus),
shing (heteropneustes fossilis), punti (puntius spp.), Tengra (mystus vittatus) etc.
36. Tana Barshi
• Tana Barshi contains one or two baited hooks having no float, is used to catch mainly
snakehead,great snakehead and wallago fish. Where small frog, various types small
fish are used as bait in the hook.
• Boal (Wallago attu), Shol, Taki, Gozar are the main fish species caught by this gear.
Choto Barshi
• Choto barshi is a type of gear which have a small stick, small thread and sigle hook.
• Main caught species are Koi (Anabas testudineus), Shing (Heteropneustes fossilis),
Punti (Puntius spp.), Tengra (Mystus vittatus) etc.
37. Kecho Barshi
• This type of barshi is having small stick.
• This type of barshi is quite known among the
children of rural area.
• Catchable species are Punti (Puntius spp.), Rita
(Rita rita), Tengra (Mystus vittatus), Kalibaus
(Labeo calbasu), Rui (Labeo rohita) etc.
