Swordfish growth pattern in the strait of Gibraltar; implications for mixing among Atlantic and Mediterranean stocks

A growth study of the swordfish in the Strait of Gibraltar was carried out, based on monthly size frequencies data collected from the Moroccan driftnet fishery during the period 2006-2011. The growth parameters were estimated by the modal progression analysis (MPA), using both the Bhattacharya and NORMSEP methods. The standard von Bertalanffy growth function (VBGF) for length was found to be: Lt =253.6 [1-exp (- 0.17(t + 1.30))]. The growth pattern of swordfish in the Strait of Gibraltar was found to be very similar to that obtained from past studies in various Mediterranean areas. Given the existing growth differences among Atlantic and Mediterranean swordfish, this suggests that the majority of fish caught in this area are most likely belonging to the Mediterranean stock. However, further studies are needed to identify the degree of mixing among stocks

Youth geographies of everyday life. Methodological notes from a project of photographic storytelling in Fez

The paper presents some methodological notes on a fieldwork in Fez, Morocco. The research involved a group of pupils from two schools belonging to different districts and culminated in the realization of two workshops of “photographic storytelling”. The aim was to verify if and how the everyday lives of the “pupil-inhabitants” had been affected by the urban projects underway in the neighbourhoods. The images and tales by the young students bring to light hidden and invisible geographies which go beyond the simple documentation of the uses, representations or emotions that link young people and space, and reveal a much more significant upshot on the political nature of socio-spatial organization and of urban transformations
