Maritime and coastal areas are the lifeblood of many countries, being essential to their well-being. They provide trade routes, regulate the climate, and supply both organic and inorganic resources, along with energy,
a crucial requirement for living and recreation. However, there are emerging disparities and barriers in terms
of marine exploitation. On the one hand, existing and evolving technologies and knowledge allow better utilization of the sea, while on the other hand, the cumulative effect of human activity leads to conflicts of interest
and to a deterioration of the marine environment. This article aims to consider the impact of changes in the
world economy on the evolution of the fishing fleet, including the characteristics of vessels produced in consecutive years. We also attempt to determine the most common type of vessel presently operating in the world
fleet. A number of external factors impact the organization and operation of the world’s fishing fleet, including
economic, geographical, and political factors. The strength of each factor varies depending on the conditions
in which the fleet operates. Also, we would also like to establish to what extent efforts aimed at energy demand
reduction have affected the characteristics of the current fleet, determining the scale and direction of change,
while also identifying any relevant constraints and limitations. The intention behind this paper is to discover
the size and structure of the fishing fleet and whether it is changing as a result of environmental transformation.
With this objective in mind, we have outlined a review of the literature and used statistical methods in order to
carry out a comparative analysis of the size and structure of the world’s fishing fleet.
