  abstract = {{W}e examined the factors controlling fish species richness and taxa-habitat relationships in the {M}almanoury and {K}arouabo coastal streams in {F}rench {G}uiana between the short and long rainy seasons. {T}he aims were to evaluate the environnemental factors that describe species richness on different scales and to define the ecological requirements of fish taxa in the two streams at that period of the year. {W}e sampled ten regularly spaced freshwater sites in each stream with rotenone. {W}e caught a total of 7725 individuals representing 52 taxa from 21 families and 6 orders. {M}ore taxa were caught in the {M}almanoury (n = 46) than in the {K}arouabo stream (n = 37). {T}hese values augmented by the number of fish taxa caught only by gill nets in a parallel survey fitted very well to a log-log model of fish richness versus catchment area in {G}uianese rivers. {M}ost of the fish taxa encountered in the {M}almanoury and {K}arouabo streams were of freshwater origin and nearly all the fish species caught in these two small coastal streams were also found in the nearby {S}innamary river with the exceptions of the cichlid #{H}eros severus$ and the characid #{C}renuchus spirulus$. {M}oreover, no significant relationship was found between a size-independent estimate of fish richness and distance from the ocean. {T}hus, despite their coastal position, the {M}almanoury and {K}arouabo streams contained fish assemblages with strong continental affinities. {A}t a local scale, independently of site size, those with relatively more habitat types harbored a relatively greater number of fish taxa. {C}anopy cover, water conductivity and bank length were the most important environmental variables for fish assemblage composition at that period of the year. {O}xygen and vegetation participated also in defining fish habitat requirements but to a lesser extent.
