We must derive far-reaching benefits from the utilization of our fish waste of every description--not only the offal arising from the preparation of the foodstuff for the table either in a fresh, kippered, cured, or canned condition, but the inedible contributions from the trawls. Those members of the sea’s vast and varied population, such as the whale, which are trapped for certain highly-prized portions of their bodies, must be fully exploited. For decades the whale fishery has been conducted along the most wickedly wasteful lines for which we are paying to-day. The Scandinavian whalers have been among the worst offenders in this respect, but they are now being compelled to turn from the folly of their ways and are endeavouring to utilize the whole of the carcases of their prizes. So far as the average member of the community in these islands is concerned it is a moot point whether he, or she, has any tangible idea of the magnitude of the British sea-fishing industry. From the abundance and cheapness of the food a vague notion obtains that it must certainly be somewhat impressive. To obtain a graphic idea of its enormous proportions we must venture beyond the limits of domestic consumption and see how we help to feed the foreigner. Under normal conditions we ship approximately 1,250,000,000 lb. of fish every year, representing in value a round £7,750,000--$38,750,000. Of this huge total the humble herring represents nearly 1,120,000,000 lb., valued at approximately £6,000,000--$30,000,000. Of the total herring catch about one thousand million--1,000,000,000--lb. are subjected to curing or salting for the foreign markets, the value of those exports being £5,350,000--$26,750,000--so that the herring may truly be said to form the backbone of the British sea-fisheries. In these circumstances, and bearing in mind the huge quantities handled, the item of waste must necessarily loom heavy. It cannot be avoided. Therefore it behoves us to turn our harvest from the sea to the utmost advantage and to eliminate the item “loss” from our operations. As the by-products from fish-waste become appreciated we may even proceed to the lengths pursued along the northern Atlantic seaboard of the United States. There the harvest of the menhaden, a fish totally unfit for human consumption, is carried out expressly for the oil obtainable therefrom. It has become a flourishing trade--one which is steadily expanding--special vessels being engaged in the fishery. While it is questionable if much fish of a comparative character and totally unsuited to the table is to be caught in the waters around our coasts, Farther Britain can point to a different state of things. Our Dominions should find it profitable to emulate the American example and exploit adjacent waters essentially for inedible fish to extract the oil and to convert the residue either into fertilizer or poultry food. There is a lucrative and developing market for all three commodities.
