Fishery -all the activities connected with the securing of animal and vegetable products from the earth waters.
Fishery products include such items as fish, clams, oysters, lobsters, eels, shrimps, turtles, seals, and whales. Pearl sponges, coral shells, and seaweeds are also included among the products derived from the sea. Fish provides the protein which is needed in the human diet. Fisheries are perhaps the most poorly managed of all the natural resources. The unscientific assumption that man can never exhaust the resources of the sea has placed upon nature the entire responsibility for renewal and replenishment.

Science and technology studies, or science, technology and society studies (STS) is the study of how society, politics, and culture affect scientific research and technological innovation, and how these, in turn, affect society, politics and culture.
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.
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.

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.

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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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

In 1950, the late Dr. Deogracias Villadolid, Director of
the then Bureau of Fisheries, brought in the first
tilapia (Oreochromis mossambicus) from Thailand
(Villaluz, 1953)..
6. OVERVIEW OF
PHILIPPINE
AQUACULTURE
Here was a fish which breeds so easily
that anyone can be a fish farmer without
having to worry about fry supply every time
as is necessary with milkfish. Thus it was
with the tilapia that the first serious attempt
to popularize freshwater fishponds was
made.

Growing market as substitute for marine
white fish
RP now 4th in tilapia output
By Henrylito D. Tacio , Special Correspondent
LOS BAÑOS, Laguna — The Philippines is now the
fourth largest tilapia producer in the world, said
Dr. Rafael D. Guerrero III, one of the country’s
leading fishery expert.
25. The Manila Times
Tilapia is a native of Africa. Its name is said
to be derived from the African bushmen’s term
for fish. Tilapia has been an important source
of food for man at least since recorded history
started. The fish Saint Peter caught in the Sea
of Galilee and those with which Jesus Christ
fed the multitudes were reportedly tilapia. An
Egyptian tomb frieze, dated at 2500 BC,
illustrates the harvest of tilapia and suggests
that the fish may have been cultured.
26. The Manila Times
Tilapia was introduced in the
Philippines in 1950 when the late Dr.
Deogracias Villadolid of then Bureau of
Fisheries (now known as Bureau of
Fisheries and Aquatic Resources or
BFAR) brought Oreochromis mossam-
bicus or Mozambique tilapia from
Thailand.
27. The Manila Times
Calling it a “miracle fish,” the BFAR promoted
its culture in backyard ponds to help the country
achieve self-sufficiency in animal protein food. But
the Mozambique tilapia’s high reproduction rate
resulted in overcrowded ponds and stunted fish,
and many Filipinos became disappointed over its
performance. In 1972, the BFAR introduced
another tilapia species, Oreochromis niloticus or
Nile tilapia. Since then, tilapia became the second
most important cultured fish in the Philippines,
after bangus.

Earned 3 degrees from
UPLB College of
Agriculture: Bachelor of
Agriculture in 1919,
Bachelor of Science in
Agriculture in 1923, and
Master of Science in
Agriculture in 1923.
29. Dr. Villadolid completed a Doctor of
Philosophy degree, major in marine
biology and minor in aquatic botany from
Stanford University, USA in 1927 as a
scholar.
30. Dr. Deogracias Villadolid,
brief background
Dr. Villadolid was the first Division Chief of
the Fish and Game Administration before the
2nd World War.
During the Japanese occupation, he was
allowed to continue serving as Director of the
Bureau of Fisheries. On suspicion that he
was assisting the Filipino guerillas against
the Japanese, Dr. Villadolid and his eldest
son Leland were incarcerated. The two later
escaped prison during an air raid.
31. Accomplishments
In 1966, the National Research Council of the
Philippines, the Philippines Fisheries Commission
and the U.P. College of Fisheries listed 146 works
authored by Villadolid which also included those
done in collaboration with other Filipino fisheries
scientists.
Dr. Villadolid received numerous awards, among
them were the Distinguished Science Star medal
and Diploma of Honor as a Philippine Presidential
Awardee in Science in 1954
32. Accomplishments
In Aug. 22, 1996, he was the first recipient of the
Dr. Shinkishi Hatai Medal for Distinguished
Service to Marine Biology of the Pacific by the
Pacific Science Association during its 11th
Congress in Japan.
33. Life after retirement
He retired from government service on March
22, 1961 on his 65th birthday.
After his retirement, he served as the Vice-
President of Araneta University and as Dean
of the Institute of Graduate Studies and
Applied Research in the same university until
his 70th birthday in 1966.
34. Life after retirement
Dr. Villadolid was awarded a plaque of merit
on the occasion of his 70th birthday
anniversary by the National Research
Council of the Philippines, Fisheries
Commission and the U.P. College of
Fisheries.
He was a trustee of the Science Foundation
of the Philippines during his retirement age
until his death. He died at age 80.
