Abstract
    Autumn-winter and spring migration of the brown shrimp are highly flexible processes in time, duration, distance and participation. Relative differences in the water temperature cause migration. The sensitiveness for this kind of stimuli varies for different categories of shrimps; berried females are on average more sensitive than non-berried females of the same size, spent males seem to be on average less sensitive than fertile males. Also individual shrimps within these categories are differently sensitive, probably because of differences in the physiological condition of the shrimps. As other important physiological processes in the life cycle of the brown shrimp are closely connected with moulting, the phase within the moulting cycle was used as a measure for the physiological condition of the shrimp. The physiological condition of individual shrimps in relation to moulting was estimated by measuring
