Based on biological and hydrological data from 1975, 1979-1982, the seasonal distribution patterns of juvenile and adult herring in the southern Baltic Sea have been identified in relation to environmental factors. During the wintering period, the distribution of herring is mainly determined by the depth of the oxygen-deficient zone and the temperature of the bottom water layer along the coastal slope. During the pre-spawning period, the distribution of herring aggregations is closely linked to the condition of the individuals' reproductive organs. During the feeding period, the main factor determining the distribution of herring is the distribution and composition of its food base. At this time, juvenile and adult herring are maximally separated, which is due to the nature of their feeding habits and the specific composition of zooplankton in shallow coastal and deep-sea areas.

The production of cold fish marinades from small fish has been analysed from the standpoint of the dictates of the national economy.
Reasons for a partly low productivity in individual sections of the production are described. From that the basic technological scheme for marinating sprats in their consumption packaging is explained on this basis and attention is drawn to the fact that efficient machines, devices and instruments for the actual performance of this method of marinating have been developed in the DDR or have been imported from the Soviet Union and other countries of the CMEA. Although these alone permit considerable rates of increase reference is made to the importance of packaging as a still unused source for raising productivity and it is shown that the packaging can also be utilized universally for a wide range of products when optimized in form and size.

The spring herring of Rügen forms the most important basis for the catches attained in our herring fisheries in the Baltic. Since the end of the sixties this stock has yielded, with increasing fishery effort, an increasing catch every year not only in the trawl fishery but also in fisheries using passive fishing gear. Good fishing conditions and the increased number of old fish are the reasons for this catch development. At present, no sudden decrease of the catch is to be expected. It can safely be assumed that the catches will decline when the temperatures in winter are average and when size of the stock continually decrease. A similar development due to a considerable increase in fishing effort cannot be precluded either.

The main object of this paper is the pelagic sprat stock of the open Gotland Sea. Meristic characteristics, growth and age composition of this stock have been compared with characteristics of other stocks. Ecological observations and the development of fisheries were studied as related fields. The relatively great mean age is an important characteristic of the sprat in the open Gotland Sea. According to these surveys, the Gotland Sea is a reservoir of old age groups of sprat from the Baltic proper. This result is of great significance for judging stock size and exploitation.
