1. FISH OR
POISSON

2. Aquatic vertebrates with fins (for
swimming) and gills (for breathing), which
represent an important source of food. At
present, more than 30000 species are known
(as many as all other vertebrates put
together). Most fish live in the seas and
oceans, at varying depths. Freshwater fish
are much less numerous. Some fish, such as
EELS and SALMON, are migratory,
spending part of their life in the sea and part
in fresh water.
Introduction

3. Broadly speaking, however they may be divided into
two distinct groups – those that live in the sea and
those that live in freshwater rivers and lakes.
In general term for recognition they are divided into
the following categories:
By Habitat –Salt Water and Fresh Water
By Physical Shape –Round Fish and Flat Fish
By Flesh Type –Oily Fish and White Fish

Classification

5. •Fish are an excellent source of protein and are low in
saturated fats and carbohydrates. Most of the fat they
do contain is polyunsaturated (unlike the animal fat
which is saturated).
•White fish have a more delicate flavour than oily fish.
They have less than 2% fat and contain approximately
80calories/100gms. Vitamin A & D are only present in
the liver.
•Oily fish, generally have darker, richer flesh. They have
8 – 20% fat and contain approximately
160calories/100gms. It contain fat soluble vitamins and
Omega3 fatty acids. These are unsaturated fatty acids
that are essential for health.
NUTRITIONAL IMPORTANCE

6. All white coloured general fishes which are available in the
market are white fish. It is divided into two categories.

7. White Fish
Round Fish Flat Fish
ROUND FISH
The shape of the round fish is generally considered as the
classic fish shape – A round tapering body with one eye on
each side of the head. A maximum of two numbers of fillet
can be taken out.

ROUND FISHES

9. FLAT FISH
It can be defined in two ways:-
1. Compressed vertically, with the eyes on the darker dorsal
(upper) surface (viz – Skates & Rays) – the ventral (lower)
surface is white, four fillet can be obtained from the fish & it
swims like a wave.
2. Compressed laterally, with both eyes either on the right side
of the head (viz –Plaice, Flounder, Dab, Sole) or on the left (viz
–Turbot, Brill), the blind side usually being without pigment,
four fillet can be obtained from the fish & it swims like a
wave.

19. We can classify fish into two categories:
1. General Fish 2. Shell Fish
GENERAL FISH -
1. Skin –Should be shiny and of good colour.
2. Colour –For white fish, the colour should be white, not faintly yellow.
3. Weight –The body weight should be proportionate in comparison with the
length of the fish and should be springy.
4. Eyes –It should be absolutely fresh and bright not shrunken.
5. Gills –It should be bright red in colour.
6. Finger Marks –If the finger marks remain after it has been pressed, then it is not
fresh.
7. Flesh –Raw flesh should not come out from the bone.
8. Scales –Should not come out very easily.
9. Tails –The tail should be stiff in nature.
SELECTION OF FISH

20. SHELL FISH-
1. Freshness –Can be recognised by the brightness of the eyes and
stiffness of flesh and tail.
2. Claws –When pulled, should spring back and both the claws are
attached.
3. Smell –There should not be any bad smell.
4. Weight –The weight should be proportionate with the body.
STORAGE
Freshness in the fish is of utmost important the period of storage should be
reduced to minimum and if at all it has to be stored, fish must be clean,
washed and dried with a fresh dry cloth. Placed on a clean tray and store
under a suitable refrigeration with the temperature limit 35°F (1.5°C) – 45°F
(7.2°C).
In case of shellfish if possible they should be purchased alive so as to ensure
absolute freshness and stored in a cool room and cooked as fast as possible.

21. FILLET- A fillet is a boneless cut such as a side of a fish.
A round fish yields 2whereas flat fish yields 4fillets.
TRONÇON - Flat fish cut on the bone
DARNÉ - Round fish cut on the bone
SUPREME - A supreme is a slice cut off a fillet,
sometimes cut at a slant. This cut is now commonly
called a pavé which means 'a slab or block' and
usually applied to cake or dessert - but now is
fashionably applied to fish!
FABRICATION OF FISH

22. GOUJONS - Strips of fillet cut 8 x .5 cm; Deep
fried(with coating), stir fry. This cut is sometimes
also known as ‘Finger Cut’.
PAUPIETTE - Fillet of fish, spread
with a farce and rolled; Poached.
‘Cravatte’ is also a cut which is from
the same cut as Paupiette. It is a fillet
tied in a knot.
DELICE - Fillet of fish neatly
folded in half; Poached.
ENTRESSE- Also known as ‘Plaited’. Fillet of
fish cut lengthwise into three and plaited.
