INTRODUCTION 9 A fishing vessel is a very complex production unit. Recognising that fishing vessels are the most complex units, Domagala and Rebizak (1965) list four production processes, which take place on a modern independant fishing vessel. They are: fishing (catching of fish), processing, storage (preservation) and transport (distribution). These processes are interdependent - but above all they depend on the fish catch. Consequently, the above authors call it the basic process, and the otherçare called auxilliary processes. The production capability, as far as processing, storage and transport are concerned are relatively easy to define and were subject of numerous researches and studies. Definition of fishing efficiency is more difficult, and the expression "fishing efficiency" is interpreted in many ways in the Polish technical literature. This is due to a number of circumstances. Each researcher can define the same phenomenon in a different way; and in addition fishing operations of vessels • - are interesting both from economical and technical aspects as well as from the biological aspect. For that reason, these Air 6 . activities are of interest to representatives of at least these three disciplines, who consider the fishing vessel from different points of view and who describe the saine naines, or who use the phenomenon often using differentsame names to describe different phenomena. The author is interested in the operation of the fishing vessel from the biological point of view, regarding it mainly as man's instrument which can affect the fish resources. It would be better if the Polish terminology, in the field of fisheries, were more standardized and more generally applied. Currently such integration is limited, both among different disciplines as well as in scientific circles working on related topics. A wider discussion of terms: "fishing capability" 11 catching power" ?fishing power" (and productivity) of fishing vessel, found in the Polish literature, exceeds the limits of the present work. Thus, I shall mention here the opinion of Niegolewski (1970) who maintains that, for estimation of economic results, for example, it is not necessary to differentiate between the concepts of potential and of actual capability of a production 7. enterprise. I consider that the above approach can be extended to the researchas such as those presented here, whose purpose is to analyze the fishing power of vessels, and which ultimately show the influence of man on the state of the resources. On the assumption that standardization of terminology 10 will form the subject of a separate, comprehensive and collective wark, I shall limit myself only to the introduction of those concepts that I shall use myself. am making the assumption that in the fishing operation the fishing vessel and its equipment or fishing gear form a fishing ensemble. The vessel by itself in a "strict sense" cannot carry on fishing operations; the same is true for most of the fishing gear (excepeEeveral types of gear used on the shore, completely omitted here). In certain cases, e.g. trawling, this relationship is quite clear, in others less so, but it exists always. Therefore, when speaking of a fishing vessel in the context of fishing operations, I shall always treat it in a wide sense, that is as a vessel operating with the aid of specific fishing gear. 1) With such an approach, I assume that fishing power of 1) The term nmoc lawcza" is an attempt to translate the term "fishing power", used in literature in the English language (Dunin-Kwinta 1964). However, the theoretical "fishing power" is close to the definition of "absolute fishing capability" of fishing gear used e.g.
