Several countries have been fishing in the Northwest Atlantic Ocean for 300 years, and recently pressure on the stocks has increased greatly. The need for conservation resulted in the creation of the International Commission for the Northwest Atlantic Fisheries (ICNAF) in 1950. By 1972 16 countries were party to the Convention.When the Convention came into force, the catch in the Convention area was 1.7 million metric tons; by 1968 this had risen to 3.9 million metric tons, after which it has declined, largely because of lower cod, herring, and haddock catches.The main objective of ICNAF is to maintain the fish stocks at levels permitting maximum sustainable yields. The first regulation applied by the Commission was the fixing of minimum sizes of trawlnet meshes used to catch a number of important demersal species. At its 1972 meeting other measures were introduced, notably the fixing of maximum quotas for several subareas and for the more important species. ICNAF is therefore the international commission which has the most thorough and extensive regulation measures.At meetings in 1971 and 1972 the Commission concluded that exploitation of the major species in the ICNAF area was extremely high and that it was necessary to reduce fishing effort. These conclusions were arrived at on the basis of intensive research. Ten years of research on cod stocks is described as an example of this kind of work. It led to the conclusion that mesh size limitations were not sufficient to maintain the stocks of cod, and this was one of the strong reasons for adoption of the quotas, a step which is of great significance in international fisheries management.

Principal Species

The Northwest Atlantic Ocean is one of the areas where fish stocks have been subjected to exceedingly high fishing pressure by many European and American countries, to the extent that some of them require strict control. International cooperation has been achieved through the International Commission for the Northwest Atlantic Fisheries (ICNAF). The Commission has applied conservation measures following scientific advice from various panels and committees, and stands as the first example of the application of national quotas for major exploited species.By 1967, increases in total catches in the ICNAF Area were accompanied by decreases in the catch per unit of effort, and it became apparent that regulations on mesh size were not sufficient to maintain the stocks. The Standing Committee on Regulatory Measures was created to consider alternative regulations, and the economic and administrative problems connected with them. A Committee on Research and Statistics was charged with preparation of scientific data on status of the stocks and measures necessary to maintain and restore them.As early as 1968, proposals were made to establish total catch quotas for principal species and to allocate these among the countries fishing. Adoption of this kind of regulation involved amendments to the Convention, and decisions were therefore difficult to achieve without a long and detailed study.At the 1969 meeting, many stocks had declined further and stricter quotas were applied. The Commission recommended changes in the Convention to allow regulations to be made on economic and technical as well as on scientific data; this was the first step on the way to fixing national quotas. The Standing Committee on Regulatory Measures recommended overall quotas for the principal species and that these quotas be shared among participating nations, taking into account interests of states with developing fisheries, states whose fleets are incapable of being diverted to other fisheries, special interests of coastal states, and historical landings. The weight to be given to these various factors was left for further negotiations.At the 1970 meeting, as only four member countries had ratified the agreements on national quotas, this problem remained unsolved. In 1971, despite further declines in catch and better research data, the Commission was still unable to agree on national quotas. But at an extraordinary meeting in January and February 1972, total quotas were established for herring in particular areas, and for national quotas. Thus for the first time in history national quotas were accepted by fishing countries. Later, overall and national quotas were recommended for the other principal species. It is hoped that this experience will be useful to other international bodies in resolving this complex problem.

Lobster Fishery

The inshore lobster fishery is one of the more important ones in the Commonwealth of Massachusetts, accounting for approximately 14 percent of the total landed value of all species in Massachusetts in 1971. Until recent years this fishery accounted for virtually all the pot landings in the state. Despite numerous attempts at conservation such as gear regulation, size restrictions, and prohibitions on harvesting egg-bearing females, the fishery has been subject to rapidly increasing effort and virtually constant landings. In the past decade it has become obvious to many fishery biologists and economists that conservation of fish stocks is a necessary but not sufficient criterion for fisheries management. Resource managers have become increasingly aware of the interdependence between economic factors and the intensity, location and composition of fishing effort.

The second annual meeting of the International Commission for Northwest Atlantic Fisheries met at St. Andrews, New Brunswick, Canada, June 30–July 9, 1952. Among the matters considered by the commission were a review of the activities of the organization since the first meeting in April 1951, permanent headquarters for die organization, election of a new chairman and executive secretary, the 1952–1953 budget, and the composition of the five sub-areas into which the commission area was divided. In addition, the commission considered recommendations formulated at a meeting of members of sub-area V held in Ottawa on February 26, 1952. The United States and Canada, who comprised the sub-area adjacent to the New England coast, recommended that the commission 1) instruct the Research and Statistics Committee to make a detailed study of all fish resources falling within the purview of the commission; 2) consider a proposed regulation for haddock fishing, including a proposal to increase the average mesh size of nets used in fishing for haddock off the New England coast; and 3) call the attention of interested governments to a recommended research program concerning haddock.

AbstractThe SEAFO Convention, signed in April 2001, is one of the first new conventions to create a regional fisheries management organisation since the adoption of the UN Fish Stocks Agreement. The negotiating history of the convention, and the way the SEAFO participants dealt with key issues in the international fisheries management, illustrates effective use of the Agreement, even before the entry into force of the Agreement, and while it remains uncertain whether all SEAFO participants will also be bound by the Agreement when it is in force. The SEAFO Convention also deals with discrete high seas stocks, not covered by the Agreement.

Equilibrium Yield

The surplus yield models of fisheries management usually assume that a concave function of equilibrium yield versus fishing effort exists. However, this function is notoriously difficult to fit to real data for a number of reasons, including the fact that few fisheries are in equilibrium. A procedure for obtaining rough estimates of these equilibrium curves is introduced. Management strategies based on these estimates and the annual yield curves are also presented. The procedures are then applied to several fish stocks.

The hydrological regime of water reservoirs in different years has a decisive impact on the abundance of commercial fish stocks and the quality of ichthyocenoses. In this connection in 2015-2016 there was conducted a retrospective analysis and ranking of hydrological regime impact on these factors. The paper gives evaluation of catches and fish stocks under different scenarios of water availability in the main fishing ponds of the Republic of Kazakhstan that give about 80% of the annual fish catch of the country (except the Caspian Sea). There were analyzed 2000 factors of hydrological regime (water level, annual discharge) and 1845 factors of fishing stocks (catches, abundance, fish biomass). The paper determines the critical characteristics of water availability for fish stocks. There have been proposed a number of administrative decisions and actions in case if water content would approach to the critical level. Among them: limitation of fish catches in the following year; widening zones restricted for fishing; intensification of safety measures of the fish young in residual ponds during arid periods; introduction of catch standards for a unit of fishing effort in low-water years, high-water years and years with normal water level in rivers.
