| Abstract |
Notothenia ramsayi Regan 1913 is the most common species of its genus on the shelf off Argentina. It was found between 36'S and 55'S. During the 31st cruise of FRV Walther Herwig in the waters off Argentina, data and samples of N. ramsayi were taken, which give some information about dependence of the distribution on depth and temperature, different spawning-times in the north and the south, different length-composition of the stock in the northern and southern parts of the investigation area, growth, length-weight relationship, size of the stock, nutrition and the relationship with commercially exploited potential predators. |
