Anchovy (Stolephorus indicus), squid (Loligo sp.) and octopus (Octopus cyanea) are among the main exploited halieutic resources in the south western region of Madagascar. Important year to year changes of their abundance (e.g. anchovy) could have drastic consequences on catches as well as for the economy of the local communities. Yearly environmental changes analysis on enrichment process in upwelling area (Chl-a), sea surface temperature, winds permitted to explain annual and seasonal variability of anchovy, squid and octopus abundance index as well as their seasonal reproduction strategy. Seasonally environmental cycle is taken in account by species for their reproduction strategy development. Results from this study show the first idea of factors and...
