FISH AND OTHER SEA FOODS

Fish in the human diet is becoming more important as the population increases at a rate far more rapid than the worlds food supply. At the present time the development of whole nations is impeded because of acute hunger that retards the health, vigor, and mental capacity of two-thirds of the whole population. These 2 billion people are suffering from protein malnutrition, yet 85 % of the 500 billion pounds of fish that could be harvested from the oceans are not currently utilized. So there is need among low-income groups for an inexpensive animal protein of high quality.

Fish flour or fish protein concentrate made from whole fish has been developed by the U.S. Bureau of Commercial Fisheries. The fat and water are extracted from the fish and the residue is milled to an odorless, tasteless flour containing 85 to 90% protein. This high protein flour can be mixed with any food such as rice, cream-of-wheat, etc. Many adaptations of this product are being used in the underdeveloped countries of the world.

Fish and shell fish are of great importance in all types of institution food services. However, the consumption of these foods in the United States is relatively low when compared with that of other flesh foods such as beef, pork, and poultry. The annual per capita consumption of fish and shell fish in 1970 was approximately 6.5 pounds fresh and frozen, 4.4 pounds canned, and 0.5 pounds cured, a total of 11.4 pounds.

Fish, if included in menus, not only brings variety to meals but makes a valuable contribution to the diet, since all the nutrients except carbohydrates are represented. These nutrients occur in varying amounts according to the kind of fish.

Protein. The protein content of fish is high, and the proteins are the valuable complete proteins. In this respect, fish resembles meat and poultry in its nutrient value.

Fats. The fat content of fish is low except in such kinds as salmon, pompano, shad, tuna, mackerel, herring, and brook and lake trout.

Minerals. Fish is important for the mineral phosphorous, and it is fairly rich in calcium. It is not such a good source of iron as meat. One of the unique values of fish is the iodine content of the salt-water varieties.

Vitamins. Vitamins of the B group are found in fair amounts in fish. Vitamins A and D are present in the fat or oil, especially the oil of the fish liver. Some of the fish-liver oils are so rich in the two vitamins that they provide a supply of vitamins A and D which are used as a dietary supplement. Cod, halibut, and percomorph liver oils are the common ones used for this purpose. Vitamins A and D are also present in the body parts of those fish in which the oil is distributed throughout the fish.

FISH PROCESSING

The fish processing industry is very widespread and quite varied in terms of types of operation, scales of production and outputs. The species of fish processed include cod, tuna, herring, mackerel, pollock, hake, haddock, salmon, anchovy and pilchards. Marine fish account for more than 90% of fish production, with the remainder being fresh water fish and fish produced by aquaculture.

In general, fish processing operations are located close to commercial fishing areas. However in some cases catches may be transported long distances or exported for processing. The Northwest Pacific region is by far the most important fishing area in terms volumes caught and processed. China, Peru, Chile, Japan, the United States, the Russian Federation and Indonesia are the top producing countries, together accounting for more than half of world fish production.

Approximately 75% of world fish production is used for human consumption and the remaining 25% is used to produce fish meal and oil. Fish meal is a commodity used as feed for livestock such as poultry, pigs and farmed fish and fish oil is used as an ingredient in paints and margarine.

Currently, only about 30% of fish produced for human consumption are marketed fish. The supply of frozen fish fillets and fish, in the form of ready-to-eat meals and other convenience food products is growing in both developed and developing countries.

The end products from fish processing may be fresh, frozen or marinated fillets, canned fish, fish meal, fish oil or fish protein products, such as surimi. Surimi is an important fish product, with the majority of catches for some species used solely for its production.

Fish processing most commonly takes place at on-shore processing facilities. However some processing can take place at sea, on board fishing vessels- for example the gutting of oily fish. In some regions of the world, where large sea fleets operate, processing can also take place on board fishing vessels.

Some sectors of the industry are very seasonal. Salmon processing, for example, may operate fewer than 100 days per year during the salmon harvesting season. During this time, plants operate at full capacity with little opportunity for down time and little incentive for waste reduction.

Edible fish and shell are readily available in todays market as fresh, frozen, cured, and canned. Freeze-dried shrimp and crab have had high acceptance in institution food services. Practically all edible fish may be served fresh although most now purchased for institutions are procured in the frozen state.

1. Fresh and frozen. Fresh and frozen fish may be processed in 6 different forms: whole or ground, drawn, dressed, steaks, single and butterfly fillets, or sticks.

a) Whole or round marketed are brought from the water. All details or preparation such as scaling, eviscerating, and removing head, tail, and fins remain to be done by the purchaser.

b) Drawn whole fish is eviscerated only.

c) Dressed whole fish is scaled and eviscerated; usually head, tail, and fins are removed. Small sizes are ready for the pan, and large sizes may be baked whole or cut into individual portions before cooking.

d) Steaks: cross-section slice of large dressed fish that is ready to cook. A cross section or the backbone is usually the only bone in a steak.

e) Fillets: sides of fish, cut lengthwise away from the backbone may be skinned. Single fillet is cut from one side of a fish; butterfly fillet is cut from two sides of the fish and held together by the uncut flesh and shin of the belly.

f) Sticks: lengthwise or crosswise pieces that are cut from fillets or steaks for individual portions.

2. Cured. Salted, smoked, and pickled fish are the three kinds of cured fish.

a) Salted fish is salted in either dry salt or brine. Then it is dried to make a product, such as dry salt codfish, or it may be held in the brine to make brine-packed salt fish, such as salmon and mackerel.

b) Smoked fish is made from a mildly salted fish followed by a smoking treatment. Usually in the modern method of smoking fish, the smoking period is of short duration and the heat is low. Haddock, kipper (large herring split in half), salmon, white fish and eel are examples of fish cured in this way. Small fish of the herring family are packed in oil after they have been salted and smoked. These include sardines, pilchards, and anchovies.

c) Pickling fish is cured in brine that contains vinegar and sometimes spices. After the process is completed, the pieces are packed in jars for further keeping. Herring is the most important kind of pickling fish, although other kinds like haddock, mackerel, and trout are sometimes pickled.

3. Canned fish. Many different kinds of fish are available in the canned form. The most popular among them are salmon, tuna, sardines, and the flaked meat of large fish, such as cod and haddock. The various kinds of shell fish, when canned, are delicacies. Canned fish has excellent keeping qualities and therefore does not need refrigeration. Once opened, canned fish must be used promptly.

IV. Read and translate the text. Name the stages of white fish filleting.

 

FILLETING OF WHITE FISH

Filleting involves a number of operations: pretreatment, fish filleting, trimming of fillets, packing and storage. These processes generally take place within separate departments of the fish processing plant.

White fish species have a low oil content and, unlike their oily fish counterparts, are generally gutted, cleaned and sometimes de-headed on board the fishing vessel. The fish are kept on ice in boxes before being delivered to the fish processing plant. On arrival at the plant, fish may be re-iced and placed in chilled storage until required for further processing.

Pretreatment. Pretreatment of the fish involves the removal of ice, washing, grading according to size and de-heading, if this has not been done previously. Large fish may also be scaled before further processing.

Filleting. The next step in the process is filleting, which is generally done by mechanical machines. The filleting department is generally separated from the pretreatment area by a wall, to prevent workers and goods passing from the non-sterile pretreatment area to the sterile filleting area. The filleting machines comprise pairs of mechanically operated knives which cut the fillets from the backbone and remove the collarbone. Some fish fillets may also be skinned at this stage.

Trimming. In the trimming department, pin bones are removed and operators inspect the fillets, removing defects and any parts that are of inferior quality. Offcuts are collected and minced. Depending on the final product, the fillets may be cut into portions according to weight or divided into parts such as loin, tail and belly flap. At a final step before packaging, the fillets are inspected to ensure they meet product standard.

Packaging and storage. Fresh products are packaged in boxes with ice, the ice being separated from the products by a layer of plastic. Frozen products can be packed in a number of ways. Fillets or pieces can be individually frozen and wrapped in plastic, but the most common method is for them to be packed as 6-11 kg blocks in waxed cartons. The blocks are typically frozen and then kept in cold storage.

IV. Read and translate the text. Name the main ways of fish storage:

 

STORAGE OF FISH

The form in which fish is bought determines how it should be cared for. It is important to follow the practices that are recommended.

Fresh Fish. In order to be sure of having a good fresh quality of this form of fish, buy it in a market where it is kept well refrigerated either resting on cracked ice or embedded in ice. Then take it home as soon as possible, cover it tightly, and place it in a very cold part of the refrigerator. The tight cover is desirable, since even the freshest of fish has an odor which might affect the odor and taste of other foods. It is best not to hold fresh fish longer than 28 to 48 hours. The same care given to fresh raw fish should be given to leftover cooked fish, and to the meat of shrimp, crab, and lobster that may be purchased already cooked.

Frozen Fish. Frozen fish is not perishable as long as it is kept frozen. The fish should be held in the freezing unit of the refrigerator or in the freezer until time to prepare it for cooking. It is best to start cooking frozen fish while it is still frozen, or at least only slightly defrosted. If, for any reason, the fish becomes thawed, it must be cooked immediately.

Cured Fish. If the cured fish is one of the salted types, it must be kept well covered and in a cool place. All the kinds of cured fish should be stored in the refrigerator. Since the curing process provides some preservation action, cured fish can be held for a longer period than uncooked fish.

Canned Fish. Canned fish has excellent keeping qualities and therefore does not need refrigeration. It may be stored in any convenient storage place in the kitchen. Once opened, canned fish must be used promptly. If it is prepared ahead of time for serving, as in being marinated for a salad, it should be placed in the refrigerator.
