Descripción
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.
