FISH MEAL - Commonly used as an ingredient of feeding mixtures. If, in its damaged condition it should be unfit for this purpose, it can also be used as compost fertilizer in so far as its price permits. Fish meal is a commodity which cannot stand much pressure and is inclined to become heated as a result of its content of moisture and fat. This liability to heat may cause the container bags to deteriorate and split open. When shipped in paper bags the effect of the heated meal may cause the bags to break when lifted. If fish meals under pressure are subjected to high temperatures there generally occurs a strong discoloration which varies in its intensity, that is to say, the meal becomes a dark color.
It is sometimes the practice at South Asian ports to accumulate stocks of Fish Meal in readiness for eventual shipment, and if these stocks are exposed to monsoon conditions there is a likelihood of their acquiring an increased moisture content through absorption from the atmosphere. In this event the liability to deterioration during transit is enhanced.
The handling of fish meal in certain ports may be very expensive by reason of the dock laborers or longshoremen regarding this as a dirty cargo or, as it is sometimes called, a "penalty" cargo, and the re-bagging charges may be found to be out of all proportion to any loss. Japanese fish meal is light golden brown in color and should be stowed in between decks in piles not more than three bags wide and six to seven bags high. Maximum ventilation should be provided. The product is subject to self-oxidation which causes color to change from light golden brown to dark brown or black. If stowed in deep holds, self-oxidation increases free fatty acid content in ratio to extracted oil. High acid content is fatal to poultry.
Peruvian fish meal is generally coarse, medium to dark brown in color; is subject to same inherent vice as Japanese fish meal.
