Book (series)Chronicle of Cuban marine fisheries (1935-1995) Trend analysis and fisheries potential 2000
Also available in:
This technical paper presents an analysis of trends in the Cuban marine fishery resources as described by a data set that covers the 1935 to 1995 period. Despite the biases that undoubtedly exist in national fishery statistics and the low level of disaggregation for some groups of species, the extended data set offers a comprehensive picture of Cuban fisheries over 60 years and makes it possible to trace down the phase of development as well as the phase of greatest expansion of Cuban fisheries. The data set shows the sustained increase of catches from the mid-1950s to the 1970s, the decrease in the growth rate during the 1980s and, starting in the 1990s, the senescence of some important fisheries. In 1995, about 38.9 percent of the resources were in a senescent phase (with consequent declining catches), 48.7 percent were in a mature phase at a high exploitation level and only 12.4 percent were still in a developing phase with some possibility of increased catches; none of the fisher ies remained undeveloped. Hence, 87.6 percent of the fishery resources are in a critical stage from the point of view of fishery management and, therefore, there is an urgent need to control and reduce the fishing effort. -

No results found.World fishery landing statistics as disseminated by FAO have been completely revised for the period 1950-1969 and time series in the database have been extended backwards by 20 years so that the period covered is now 1950-1994. Through a preliminary analysis of trends, globally and by oceans, we attempt to demonstrate that these extended time series can be very useful in interpreting developments in the world’s fisheries and so help in assessing the present situation as well as for planning and policy-making for the future. Grouping the 200 most important resources into a few categories according to the shapes of their landings trends reveals a variety of patterns which seem to form different segments of a generalised fishery development model comprising undeveloped, developing, mature and senescent phases. The analysis demonstrates strikingly the succession of the passage of the majority of the world’s major resources through these phases, indicating the current general saturation of fisheries development and increasing overexploitation. Fisheries potential was estimated by predicting at which point the relative rate of increase of landings is zero, using the same generalised fishery development model applied to total fishery production data for marine fish and shellfish. The analysis was applied using data aggregated to three different levels, namely (1) a total for all oceans, (2) totals for each ocean, and (3) individual FAO major fishing areas. Estimated fishery potent ial for the world’s oceans increases as the level of aggregation of the data decreases, and the results indicate that marine fishery potential may be higher than has been assumed up to now. The areas and resources which might provide potential increases in production are identified. -
DocumentMarine fisheries statistics in the Hashemite Kingdom of Jordan
an expanded plan of development
1984Also available in:
No results found.The paper evaluates the status of marine fishery statistics in the Hashemite Kingdom of Jordan and describes the type of data that are needed for economic evaluation of fisheries and biological/stock assessment studies. A one-year plan of development of an adequate statistical system in Jordan is proposed. The system is based on regional concepts and uniform definitions of statistical items to facilitate inter and intra country comparability of the collected fishery data. The methods of collecti on of data and their subsequent analysis are described in details; the facility requirement by way of manpower and equipment is examined. The cost estimate for running the one-year programme is worked out and the potential benefits are indicated.
