The production of freshwater fish for food

It has been estimated that in England and Wales fresh water covers some 340 square miles of which about one quarter is inhabited mainly by salmon and trout; in Scotland the lakes cover an area of 340 square miles. The principal object of this publication is to make available in handy form some of the methods, especially those involving the use of manures, by which crops of fish from water can be increased. The cultivation of water which this implies may be compared directly to the cultivation of farm land: the conditions for growth are made as favourable as possible, the seed is sown in the form of young fish, and after one or perhaps two growing seasons the crop is harvested. There are however many waters about the country where marketable fish are already available and can be removed without prejudice to, and indeed to the advantage of, sporting fisheries. In such cases it is necessary only to remove the fish and to rely on the natural processes of reproduction of those which are left to repopulate the water. Farming waters in the true sense is the concern of the greater part of this publication; the removal of crops of otherwise unwanted fish is considered in the last two sections on perch trapping and eel fisheries.

Commercial utilization of dolphins (porpoises) in Ceylon

Two species of mammal dolphin are found in waters adjacent to Ceylon, namely the common dolphin (Delphinus delphis) and the bottled-nosed dolphin (Tursiops truricatus). Both these species are predators and cause damage to finishing nets by attacking fish trapped in them. This menace to nets is particularly pronounced when fish populations in a particular area become somewhat depleted. Dolphin can be successfully captured from a motor boat by use of a simple hand harpoon with a detachable dart and bladder buoy. Fresh dolphin meat when placed on the market sold readily despite some local prejudice against the naturally dark colored meat. The flesh of the dolphin is nutritious and can be used successfully in both western and eastern types of cookery.
