Fish and invertebrates are subject to a wide range of disease agents. Many of their diseases are probably local in origin although a lengthy list of infections were probably imported via the vast array of exotic species which have been transferred to virtually all areas of the world. Since ail living organisms carry a full suite of microorganisms and larger parasites the likelihood of there being pathogens for local species among them is good. Introductions can occur in at least one of three separate ways: (1) intentional introductions for specific purposes, (2) accidental transport of biological agents via massive transfers of ballast waters or (3) through the ornamental or aquatic pet trade. Control measures and information services devised by the International Council for the Exploration of the Sea, the European Inland Fisheries Advisory Commission and the Office International des Epizooties are described.

The Council of the Food and Agriculture Organization (FAO) held its 26th session in Madrid, June 3–14, 1957, under the chairmanship of S. A. Hasnie. During its discussion of current FAO activities the Council 1) decided to accept the invitation of the United States government to act as host to the fifth World Forestry Congress in 1960; 2) agreed to the proposed procedures for organizing the second session of the joint Food and Agriculture Organization/Economic Commission for Europe Committee on Forestry Working Techniques and the Training of Forest Workers, which was to be held in Moscow in September 1957; 3) established the European Inland Fisheries Advisory Commission to promote improvements in inland fisheries and to give advice on the matter; 4) approved certain budgetary amendments to the constitution of the European Commission for the Control of Foot-and-Mouth Disease; 5) received the report of a mission which had been appointed in 1951 to examine the Moroccan agricultural and food supply situation arising from drought conditions, noted subsequent developments and the intentions of several governments to assist Morocco, and requested the Director-General to keep the situation under review and to take further steps which might be necessary; and 6) requested the Director-General to examine the advisability of establishing a committee on settlement, resettlement, and agrarian reform, as proposed by the government of Israel.

The effect of suspended solids on freshwater fish is illustrated from field and laboratory studies on china-clay wastes together with work on the effects of other chemically inert material, wood fibre, ferric hydroxide, and oxidizable organic solids, and mention is made of work in the marine environment. Tentative water quality criteria formulated by the European Inland Fisheries Advisory Commission for inert suspended solids and inland fisheries are outlined and compared with conditions prevailing in rivers in the United Kingdom. Reference is made to current work by the Water Pollution Research Laboratory on the role of organic suspended matter in the presence of soluble poisons and on the effect of hydraulic conditions on the settlement and oxidizability of suspended solids from sewage effluent.
