| Within the frame of the National Program (PNM), 'Assessment of Marine Tunisian Resources' (1996-1999), two prospecting surveys on small pelagic fishes, have been led in narrow collaboration with French Institute IFREMER. Their objectives were to specify the relative fishes abundance, their spatial-temporal variability but also to quantify the maximum sustainable yield (MSY) of this resource. A third important goal was to familiarize a Tunisian scientist team, with numerical methods and data processing used during the cruises (reading of echograms, treatments of data, etc.) in stocks assessment. It is known that the indirect stocks assessment methods of small pelagic species is not reliable, reason for which we opted to apply echo - integration techniques.... |
