  • Fishing vessel collisions are accidents which, in most cases, give rise to otheraccidents such as explosions, water on board and even sinking. These are accidents which often have fatal consequences for the crews and in many cases signi-fy the loss of the vessel. Such losses can be avoided or reduced if the fishing ves-sels are equipped with the appropriate technological means and their crews proceed correctly and promptly. Thus, national governments should include in theirregulation of the fishing sector control mechanisms that guarantee that the vessels are endowed with the adequate resources and with crews well-trained insafety. These resources and their distribution must be assigned in accordancewith the needs of the fleet, which requires an in-depth knowledge of the degreeof concentration of accidentality by collision of the fishing sector of a country.In this context, the aim of this work is twofold: first, to formalise a methodology for the fishing sector of a country which allows the inequalities in the concentration of collisions to be analysed; and second, to apply this methodology tothe Spanish fishing fleet for the period 1994-2002. Thus, indices are constructedby region and by fishing types for two variables: fishermen and fishing vessels. Inthese areas, results are then obtained both for the concentration of collisions andfor their associated Lorenz curves. An increase in the inequalities in the spatialand functional distribution of these accidents is observed.
