LEGAL PROBLEMS OF THE FISHERY The new thread herring fishery has been beset with conflicts reminiscent of those in the menhaden fisheries. Sport fishing inter- ests have become aroused, bait dealers and gill net fishermen are concerned, and con- servationists view developments with mis- givings. The State of Florida does not allow the taking of food fish with purse seines in territorial waters (out to miles on the Gulf coast). The law was initially interpreted to include incidental food fish captured in thread herring sets. In November and De- cember 1967, enforcement of the law caused the temporary withdrawal of the Louisiana vessels from the fishery. A court decision in February 1968 included an interpretation that allows a certain percentage of food fish in industrial fish catches, subject to admiinistra- tive regulation by the Florida Board of Con- servation. As a result, prospects for con- tinued development of the fishery are good. SHOULD THE FISHERY CONTINUE? The world demand for animal protein is increasing steadily. Marine fish, particular- ly clupeoids, are becoming more important in supplying that need. Chapman noted in 1967 that the trend in world fish catches shows an increase in landings of clupeoid fishes from one-quarter of the catch in 1948 to about one- half in 1965. He inferred these reasons for the increased production: (1) the ocean con- tains more of them than of any other group presently harvested, (2) they congregate in large shoals that can be caught efficiently and cheaply, and (3) animal-husbandry practices in the past 20 years have been revolutionized by adding animal-protein supplements, pri- marily fish meal, to the diets of domestic fowl and mamnaals. Despite increasing world utilization of industrial fish for animal food and industrial products, production in the United States has declined steadi
