The distribution of Z. patagonica in discrete beds along a large latitudinal gradient (approximately 20º) of the Atlantic coast is expected to generate different patterns of growth, aging, and/or morphometric characteristics, and reproductive events. Therefore, it is important to identify possible differences between beds in order to perform bed-specific stock assessment. Thus the purpose of this work is to evaluate if there are differences in the key biological reference such as morphomet...
The distribution of Z. patagonica in discrete beds along a large latitudinal gradient (approximately 20º) of the Atlantic coast is expected to generate different patterns of growth, aging, and/or morphometric characteristics, and reproductive events. Therefore, it is important to identify possible differences between beds in order to perform bed-specific stock assessment. Thus the purpose of this work is to evaluate if there are differences in the key biological reference such as morphometry, growth rates, maximum age and age/size at first maturity in the main beds along their extended latitudinal distribution in the South-western Atlantic.
