There are three classes of fish


Oily fish: oily or fat fishes have the fat distributed all over their bodies eg: all kinds of herrings, mackerel, all kinds of sea bream and salmon

White fish: white or lean fish have most of their fat deposited in the liver and not between the fibres. The oil from the livers of some large fish is extracted and sols for medicinal use, eg: cod-liver oil or halibut-liver oil.

Shellfish: shellfish have a protective covering of shell. There are two kinds:
i.    Crustaceans, eg; crab. Lobster, crayfish, shrimps
ii.    Molluscs, eg snails, oysters, mussels.

Constituents of fish
1.    Protein: fish contains a large proportion of protein; therefore, it is a valuable body-building food. Dried fish has a high food value because it contains weight for weight more protein.
2.    Fat: oily fish is of more value than white fish because the fat, which is rich in Vitamins A and D, is distributed throughout the flesh of oily fish. In white fish the fat is found only in the liver, which is usually disposed of except that of large fish like cod. For this reason, white fish is more readily digested and is more suitable for invalids.
3.    Vitamins: oily fish is rich in vitamins A and D
4.    Water: this is more abundant in white than in oily fish
5.    Mineral matter: calcium is present in the bones of fish and in snails.

Choice of fish
1.    Fresh fish has no unpleasant smell.
2.    The eyes are prominent and bright.
3.    The gills are bright and red
4.    The scales are bright, shining, and plentiful.
5.    The flesh is firm, not flabby and the body is stiff.
Fish is cheapest and best when in season. Buy just what is needed for a short period if no refrigerator is available, because fish decomposes quickly in a hot climate.

Preparing fish for cooking
1.    Cover the table with newspaper or any sheet of clean paper. The paper protects the table, and the scales etc should be wrapped in it.
2.    Handle the fish carefully
3.    Cut off the fins and trim the tail with a pair of scissors kept specially for use in the kitchen. If no scissors are available use a sharp knife, but this tends to damage the flesh if care is not taken.
4.    Remove the scales by scrapping from the tail towards the head with a kitchen knife.
5.    Slit open the underside or belly, starting from the head. Remove the entrails carefully, remove blood and dark skin.
6.    Reserve the roes if any. Wrap entrails and scales up in the paper and dispose them off immediately, as the smell quickly attracts flies.
7.    Wash the fish thoroughly, but do not allow to soak, as soaking  makes it soft.

8.    Rub a little salt on the inside to remove the black skin, rub half a lime all over the fish to remove the fishy smell. Rinse quickly in cold water.
9.    Dry with a cloth. Cut up and season with salt and pepper. Fish may sometimes be cooked whole if they are small.
10.    The head should be thoroughly washed and rinsed because it is slimy. Rub inside with lime.
To filet fish
1.    Scale in the usual way. Cut off the head.
2.    Using a sharp knife cut the flesh down the backbone, cutting as near to the bone as possible. Remove the flesh from one side and then from the other.
3.    Wash fillets quickly, and use as required.
Preparation for dried fish
1.    Wash thoroughly to remove sand or grit
2.    Remove the head and fins
3.    Remove scales or skins
4.    Flake or cut in moderate sized pieces according to the purpose for which it is required.
Methods of cooking fish
Frying:  This is the most popular method of cooking fish. It is tastier and more attractive than fish cooked by other methods, but it is less digestible and therefore it is not suitable for the sick and young children. Fish is usually fried in shallow fat, and the remaining oil, which contains some of the goodness; is used for making the gravy for the fried fish. (Fish fried in large quantities foe sale should be fried in deep fat. This method is quicker and more economical)
    Whenever possible coat fish before frying
a.    To prevent the fish from being in direct contact with the hot oil
b.    To keep the shape of the fish
c.    To conserve the nutrient of the fish.
Coat with:
i.    Seasoned flour i.e, flour to which salt and white pepper have been added, or
ii.    Egg and breadcrumbs or
iii.    Batter
Stewing: this is a common method. Stewed fish is nutritious and more digestible than fried fish because only a little oil is needed. It is economical, as though cuts can be used. It is nutritious because nothing is wasted. As the liquid only simmers there is less likelihood of the fish breaking. The coated fish is fried and some flour is fried in the oil, then the vegetables and water or stocks are added. This is brought to the boil and allowed to simmer till the vegetables are soft. The fried fish is then put in and the stew is simmered until the flavors have been drawn out and the consistency is correct.
Boiling: this is rather wasteful as many of the nutrients are drawn out into the water and lost. The fish is inclined to break. The water, however, can be used as stock for soups, sauces and gravies.
Steaming: this is the most desirable method of cooking fish for the sick. The flavor and goodness are conserved in the fish. Fillets of fish are the best, but small whole fish as well as thin cuts can be used.
Baking: this is not so common method. Whole large fish or rolled filets may be stuffed and baked in a moderate oven.
Grilling or roasting: herrings and other small fish are suitable for this method, but the oil and nutrients escape into the fire though the fish is tasty and attractive when cooked. Fish cooked by this method should be well seasoned.
