FOR a number of years past, British inshore fishermen have experienced difficult times due mainly to scarcity of fish on the grounds which they work. The problem of how best to bring about an improvement in these fisheries is a very difficult one which, for some considerable time, has occupied the attention of local fishery committees and other interested bodies. It is generally agreed that the capture and destruction of young fishes, too small to be landed and exposed for sale as a food commodity, are against the best interests of any fishery. With only one exception, the fishing methods at present in general use do not cause wasteful destruction of young stages. There cannot be the least doubt, however, that trawling works great havoc amongst fish stocks by indiscriminately capturing and killing not only marketable but also the small unmarketable members. The most obvious and satisfactory way, therefore, of preserving fish populations and main taining successful fisheries, would be to prohibit trawling altogether. For many reasons such drastic action cannot be taken. What then are the other possibilities, if any?
