Transgenic fish or genetically modified fish(GM fish) are genetically modified organism. The DNA of the fish is modified using genetic engineering techniques.
Aim is to introduce a new trait to fish
GM fish has been approved by FDA
Fish meal has been used as a feedstuff since the 19th century in Northern Europe and is now used worldwide. Global production of fish meal has been stable for the past two decades at around 5 to 6 million tons, Peru and Chile being the main producers.
A major portion (more than 60%) of fish meal produced globally is used for aquaculture (farming of finfish and shrimp). The intensification of aquaculture in Asia, and particularly in China, is increasing the demand for fish meal even though the supply cannot grow accordingly. Natural phenomena such as the El Niño-Southern Oscillation affect the fisheries along Central American Pacific coasts, leading to seasonal scarcities and increased prices. Due to these factors, the fish meal market is volatile and prices often shoot up. The search for suitable and cost-effective alternative protein sources for use in industrial aqua feeds will be the most critical factor in the development of intensive aquaculture in Asia (Kaushik, 2010; Steinfeld et al., 2006).

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.

2. introduction
• Fish is one of the protein rich foods of humans since ancient
times.
• Also known as poor man’s diet.
• Fish is also the world’s best source of omega-3 fatty acids,
which are incredibly important for our body and brain.
• About 1/3rd of world catch of fish is not used for direct human
consumption but for production of fish byproducts.
3. Fish byproducts
• A byproduct is a secondary product derived from a
manufacturing process or chemical reaction .
• Due to unavailability of ready market and non nearness of
market, fish is preserved as food yet other utilizations of fish
in which protein , fat and other useful contents are processed
into a number of valuable byproducts.
4. Fish by-products include:
Fish Oil
Fish Meal
Fish Silage
Fish Glue
Fish Fertilizer
Tatami Iwashi
Isin Glass
Fish Skin
Fish oil
Fish meal
5. Fish oil is derived from the tissues of oily fish or from the fat
of cold water fish such as Anchovies, Mackerel and
Sardine.
Fish oil approximately has 25% saturated and
75%unsaturated fatty acids.
Omega 3 essential fatty acids (EFAs) are key ingredients of
fish oil. These EFAs are:
docosahexaenoicacid (DHA) and
eicosapentaenoicacid (EPA)
Fish oil
6. Fish Liver Oil
Liver is chopped into small pieces and is boiled into sufficient
water.
The oil is skimmed off from the surface of water.
Composition :
Fat 55- 75%
Protein 5-10%
Water 20-36%
Vitamin A and D
It has high levels of the omega 3 fatty acids, eicosapentaenoic
acid(EPA) and docosahexaenoic acid (DHA)
Sources of liver oil are Cod, Haddock and Shark.
7. Benefits of Fish Liver Oil
Cod liver oil can cure both ‘rickets’ and ‘exophthalmia’.
The fish oil is helpful in the growth of teeth and bones.
DHA is the most vital component in the development of the
fat in the brain of the fetus.
DHA also benefits the nervous system and the eyes.
EPA strengthens the cardiovascular system, reduces the risk
of heart disease and strokes, and lowers triglycerides.
EPA work to ease the pain and discomfort of arthritis.
8. Fish Body Oil
• Oil is extracted from either whole fish or fish
fat
• It varies in colour i.e. pale yellow to light
brown to brown.
Composition :
Polyunsaturated fatty acids, particularly
omega-3-PUFA .
• Sources :
Sardine, Pilchard, Herring
9. Benefits of fish Body Oil
• It is used in the manufacture of soaps and candles.
• It is used in oiling the bottom of the boats to protect them
against sea-rot.
• It is used in manufacture of paints and varnishes that are more
resistant to heat.
• A good quality oil is clear pale yellow to brown in color ,
while dark colored oil is of inferior quality.
10. • Fish Meal is a dry powder prepared from whole fish or from
fish filleting wastes which are unacceptable for human
consumption.
• It is used as a high-protein supplement in aquaculture feed.
Composition:
• High-quality fishmeal normally contains between 60% and
72% crude protein by weight.
Fish meal
11. Benefits of fish meal
• Increases feed efficiency through better food palatability, and
enhances nutrient uptake, digestion, and absorption.
• The balanced amino acid composition of fishmeal promote fast
growth and reduce feeding costs.
• The nutrients aid in disease resistance by boosting and helping to
maintain a healthy functional immune system.
• Helps to reduce pollution from the wastewater effluent by providing
greater nutrient digestibility.
• Mukene fish powder contain high levels of Ca, Zn, Fe, P and Se
(FAO).
12. FAO Report 2015
Globally 795 million people are malnourished.
1.2 billion people are iron deficient .
WHO estimate that every second pregnant women & 40%
infants are anemic.
10 gms of Mukene powder provide 10 % of daily needs of
iron intake among children.
10 gms of Tuna backbone powder provides 3.6 mg of iron or
40% recommended daily iron needs.
13. Fish Silage
• It is a liquid product made from whole fish or parts of fish
that are liquefied by the action of enzymes in the presence of
an added acid.
• It can be made from spoiled fish, sub-utilized species and
commercial fish waste.
• The proteins present in the fish silage can also be hydrolyzed
to free amino acids, making the silage the most available
source of amino acids for protein biosynthesis.
14. • Fish glue is made by boiling the skin, bones and swim
bladders of fish.
Applications:
• Used to repair animal-based sheets called parchments,
which are used for writing.
• Used in painting materials by some artists in China..
• Act as a binder, glazing agent, or protective coating
for paintings.
• Used for building and repairing wooden antiques, as
well as building new products.
Fish glue
15. Fish Fertilizer
• It is an awesome product for promoting
plant growth.
• The waste obtained during the preparation
of fish meal is widely used as manure for
coffee, tea & tobacco plantation.
16. Types of fish fertilizer
• Dry Fish Manure:
It is obtained from destroyed fishes.
Whole fish is dried in sunlight and used as manure.
It contains 5-7 % N, 4-6% P and 4-6% Ca.
• Pit Manure:
It is obtained by burning the fish wastes into the pits prepared in the soil & left
for 35-60 days & allowed to dry in sunlight after fermentation.
It contains 3-5% N, 3-6% P & 1-5%Ca.
• Fish Guano:
The refuse of cooked fish body obtained after proper pressing during the
extraction of oil is fish guano.
It contains Nitrogen 8-10%, Phosphoric acid & disintegrates easily in the soil.
17. Tatami iwashi

baby Sardines laid out and dried while entwined in a single
layer to form a large mat-like sheet.
• It can then be cut to various sizes and used in different ways.
• Common serving styles include use as an ingredient in soup
or cut into small pieces for use as a snack or accompaniment
to sake or beer drinking.

• Isinglass finings are widely used for clarification, of beer
particularly in the production of cask-conditioned beers, known
as real ale.
• Isinglass was used as a preservative for fresh eggs which were
submerged in it.
• Isinglass is also used to help repair parchment.
• Act as an emulsifier.
20. Fish Protein hydrolysates
• It is produced by the use of enzymes to break down fish
proteins into amino acids (proteolysis).
• The resultant product is highly functional, contributing
whipping, gelling and texturing properties when used as an
ingredient in food products.
