To understand the principles of fishmeal and oil manufacture, it is necessary to consider the raw material as composed of three major fractions: solids fat-free dry matter , oil and water. The purpose of the process is to separate these fractions from each other as completely as possible, with the least possible expense and under conditions rendering the best possible products.
Fish can be reduced to meal and oil in a number of ways. Common to all methods of practical importance are the following processing steps: heating, which coagulates the protein, ruptures the fat depots and liberates oil and physico-chemically bound water; pressing or occasional centrifugation , which removes a large fraction of the liquids from the mass; separation of the liquid into oil and water stickwater. This chapter deals in some detail with the most generally practised method of large-scale production.
A more cursory description is given of small-scale processing and plants designed to handle small and irregular landings of fish or to yield products with special properties. Although the basic principles of the process may appear few and simple, a variety of elements is required to make a smooth running and profitable factory. There are also different types of equipment that will do the same job but in different ways.
The number of options have increased considerably during the last years, particularly in the fields of energy saving, automation and environmental protection. The prospective manufacturer should therefore devote ample time and attention for consultations with the most competent suppliers of machinery and complete factories, before making his final decisions on layout and equipment.
Here are some factors that need special consideration at the planning stage. The most important prerequisite for a profitable fishmeal project is an ample and regular supply of raw material at an acceptable price. Length of season, that is how many days per year the plant may be in operation, is of the utmost importance for the profitability of the venture. Furthermore, the longer the season, the greater the weight that should be placed on measures to reduce the variable costs, and the more that should be spent on investments to save labour and energy and to ensure higher yields and quality of the products.
Another important point relates to the size of plant needed for the amounts of raw material in question. Capacities given by the equipment manufacturer, particularly for the cooker and press installation, may serve only as indicators at the preliminary discussions.
The yield is an empirical value entirely dependent upon the nature of the raw material to be processed, its size, freshness and texture. The composition of the raw material expressed in terms of dry matter, protein and fat, will determine what yield of products may be expected. The fat content is of special importance at the planning stage, because it will decide whether it will pay to install equipment for the recovery of oil, besides telling what yield of oil may be expected. Furthermore, they eliminate a serious pollution problem that today appears unacceptable, particularly in the vicinity of densely populated areas.
For small factories and irregular operation, omission of evaporators may sometimes be justified, but a final decision on this point should be taken only after careful calculations have been made and the pros and cons thoroughly evaluated.
Location of the plant relative to habitation and closed harbours is another feature of the utmost importance for trouble-free operation.
Public regulations protecting the environment against undesirable pollution of air and water should be carefully studied, as these will affect the selection of equipment and factory premises and determine the amount necessary for investment in unproductive installations for odour abatement and cleaning of waste water emissions. The bulk of the world's fish meal and oil is today manufactured by the wet pressing method. The main part of the sludge in the press liquor is removed by centrifugation in a decanter and the oil is subsequently removed by centrifuge.
The stickwater is concentrated in multi-effect evaporators and the concentrate is thoroughly mixed with the presscake, which is then dehydrated usually by two-stage drying.
The dried material is milled and stored in bags or in bulk. The oil is stored in tanks. Figure 2 shows the flow diagram of a typical fishmeal and oil plant. As already pointed out, there are alternatives to this layout and also different types of equipment to choose among for some of the unit operations.
The most important alternatives will be mentioned in the following descriptions of the various processing steps. Referring again to Figure 2, we shall now follow the material step by step through the factory.
The raw material is first unloaded from the fishing vessel by crane, wet fish pump, pneumatic elevator or some sort of mechanical conveyor.
The fish is weighed or measured by volume before it is transported to the pits or tanks for the storage of raw material. Large fish are hashed A while smaller fish for example, those less than 40 cm long are fed directly at a constant rate by the feeding machine B to the indirect steam cooker C.
The coagulated mass is pre-strained in a strainer conveyor D , or in a vibrating screen, before entering the twin screw press E. The products from the press presscake and press liquor are treated as follows. The presscake is disintegrated in the tearing machine wet mill F to facilitate mixing with stickwater concentrate see below and drying in an indirect steam dryer or a direct flame dryer G. The meal passes through a vibrating screen H furnished with a magnet to remove extraneous matter like pieces of wood and metal for example, fish hooks before entering the hammer mill J.
The ground meal is automatically weighed out in bags by the scales K , the bags are closed e. Alternatively, the meal is stored in a holding and blending silo before bagging, pelleting or storing in bulk. To remove most of the sludge, the press liquor passes through a decanter N. The press liquor then passes through a buffer tank O before separation into oil, stickwater and fine sludge in the stickwater centrifuge P.
The sludge is added to the presscake. The oil passes through a buffer tank R before water f and sludge impurities are removed polishing in the oil separator S. After polishing, the oil often passes through an inspection tank before storage in the oil tank.
The stickwater passes through a buffer tank T before concentration in a multi-effect evaporator U. After the buffer tank V , the concentrate is mixed thoroughly with decanter-sludge and presscake before drying.
In some cases the stickwater concentrate, called condensed fish solubles, is sold separately. As indicated in Figure 2 heavy dotted line , the factory can be deodorized by air suction from all tanks and machinery. Methods of effective deodorization are still under study and reference should be made to Section 4. As stated, large fish have to be hashed into smaller pieces before being passed by the feeder into the cooker. This is to ensure uniform processing and equal temperature in the cooked material.
Also, the feeder ensures a steady rate of presentation to the cooker. Figure 3 illustrates one type of hasher often used. It consists of a rotor with staggered knives and a frame with a row of stationary knives. Figure 4 illustrates an example of a feeder. It consists of a hopper from the bottom of which the raw material is carried to the cooker by a screw conveyor. The conveyor's speed may be adapted to the rate of throughput desired by means of a stepless gear.
When the hopper is full of raw material, a level control mechanism stops the removal of raw material from the raw fish pits or silos. When the level has sunk to a fixed lower level, another level controller starts the intake flowing again. Today pumps are increasingly used for the transportation of raw material, and these can easily be controlled by the automatic level controller of the hopper. Figure 5 gives an example of a so-called mass balance.
Here we can follow the streams of the three major fractions of the raw material, solids fat-free dry matter , oil and water, through the factory. The actual figures will, of course, vary with the composition of the raw material, particularly with the oil content, but the diagram is sufficient to illustrate the general trend. The prospective manufacturer may estimate his expected yield of meal on the basis of the dry matter content of his raw material plus moisture and residual fat in the meal.
Likewise, the yield of oil will be the fat content of the raw material less the small amount 2. In the following sections we shall take a closer look at the various unit operations of the process. The purpose of the heating process is to liberate the oil from the fat depots of the fish, and to condition the material for the subsequent treatment in the various processing units of the plant.
The oil is then free, and theoretically it should be possible to separate it from the solid material. The problem is primarily a question of heat transfer and temperature control to ensure a uniform, optimum temperature throughout the whole mass. Since reduction of heat load on the material, that is the combined effect of temperature and time, tends to improve the quality of the products, we may expect new technological answers to the heating problem, in line with this new knowledge.
However, at the present state of technology, we have to accept that optimum conditions for a particular type of raw material must largely be established through practical experience.
The most common practice is to cook the fish in a steam cooker, through which it is conveyed continuously. Heat is generally transferred indirectly from a surrounding jacket and a heated rotary screw conveyor. This is an improvement over the direct steam injection cooker, in which water is condensed in the mass during the process and has to be removed by the press and then evaporated from the press liquor.
However, in indirect cookers provision is also made for the admission of live steam directly into the mass as this may sometimes be advantageous.
Cooking is an exacting operation in production and is sometimes difficult to control. Production of cooked material which can be readily pressed is dependent on the quality of the raw material and on the process conditions.
A precise time-temperature programme for this process can therefore not be set up and, as mentioned above, a process of trial and error is generally required when fish of unknown history is processed. The proof of good cooking is good pressability of the mass which leads to proper removal of press liquor and, in particular for fatty fish species, efficient recovery of oil, giving a meal with low fat content which is a criterion of quality.
The process must be controlled to ensure sufficient cooking, but overcooking must be avoided as this results in problems with pressing and the presence of large amounts of suspended particles in the stickwater, which makes evaporation difficult. A typical continuous indirect cooker is shown in Figure 6. The cooker is designed as a cylinder having a steam heated jacket throughout and a steam heated rotor, designed as a screw conveyor with hollow flights.
The cooker is equipped with covers throughout for inspection and cleaning and with a nozzle system for blowing direct steam into the mass. The cooker may be provided with automatic temperature control equipment, automatic level control for raw material feeding, discharge control equipment which is required particularly for handling soft raw material and a trap for collecting heavy foreign matter like stones and scrap iron.
Cookers like this are generally available in sizes which can process from 16 t to 1 t of raw material per 24 h. The capacity of a heat exchanger, such as an indirect steam cooker, is proportional to the area of the heating surfaces and to the temperature difference between the two sides of the wall. Furthermore, the capacity is influenced by the resistance to heat transfer largely caused by the existence of films and coatings on the heating surfaces.
An important way of reducing the tendency to scaling, caused by coagulation of protein on the hot walls, is to use moderate steam temperatures, especially in the early stages of heating.
Another measure is, of course, to introduce and enforce good routines for effective cleaning at regular intervals. An entirely different type of heating device is the so-called Contherm apparatus , recently tried out in connection with fishmeal and oil manufacture. The results, so far at low rates of throughput, have been quite promising. The apparatus shown in Figure 7 consists of a vertical cylindrical heat exchanger provided with an agitator keeping the material in rapid movement, thus contributing to effective heat transfer.
During rotation, the agitator blades knives are pressed against the surrounding heating surface in order to prevent the formation of scale.
To reduce the viscosity of the material and to increase the rate of heat transfer, some stickwater should be added to the fish.
Advantages of the Contherm heater are rapid heating with a holding time less than 2 min, effective temperature control, and quick and easy routines for dismantling and cleaning. Another innovation is the tubular heater pre-cooker primarily designed and used for the utilization of waste heat, either from the evaporators or from the dryers.
Because of the relatively low temperatures of these vapours or gases, they are particularly useful for preheating the raw material.

The way to a fish's stomach is through his eyeballs, and fishing lures are objects that resemble any of the naturally occurring foods that fish might find attractive. The purpose of the lure is to use movement, color, and vibration to grab the fish's attention and cause him to bite the hook. Lures also seem to have the purpose of attracting the fishermen's attention. Lures fall into several broad categories, each with specific characteristics that catch the fish's attention.

3. THE PROCESS
In this book, for the first time, scientists from various disciplines and all partners in the fishery chain address the important issues of quality labelling, monitoring and traceability of fish. The complexity of the European fishery sector, the attitudes towards quality labelling GMP and the needs for quality information are presented. The progress of implementing traceability schemes from catch to consumer is covered. Fishermen give their view on GMP on board of their vessels. New tools for measuring the quality of the catch and the experience with quality grading of the landed fish by QIM are described. Attention is paid to recent developments of E-commerce of fish via the auctions. The possibilities of combining various instrumental methods for measuring fish quality are highlighted.
For the purposes of this web page, "fish" means any marine animal, including shellfish and crustaceans, and any of their parts, products and by-products [1, SFCR]. This section summarizes the labelling requirements that apply to imported fish and fish products, as well as those that are manufactured, processed, treated, preserved, graded, packaged or labelled in Canada for interprovincial trade and for export. In some cases, the labelling requirements would also apply when these are intraprovincially traded. Provincial regulations may also have labelling requirements that apply when these products are sold within that province.
