Seagrass meadows play a major role in fisheries productivity through nursery function of fish larvae; however, little information is available on the seasonal distribution of fish larvae in seagrass meadows at a large spatial area of East Africa. The present study investigated the seasonal variability of fish larvae abundance and community composition associated to environmental variables in seagrass habitats across coastal East Africa (Kenya, Tanzania). The results showed differences in fish larvae abundances and community compositions across seasons were site-specific and primarily influenced by contemporary environmental conditions driven by factors such as water temperature, salinity, chlorophyll a and currents velocity. We found higher mean fish larvae abundances during the northeast monsoon (NEM) season compared to the southeast monsoon (SEM) season in the northern-most sampling areas located on the Kenyan coast. In the two Kenyan areas (Watamu and Diani), fish larvae community composition was similar across seasons, whereas it differed significantly between the two monsoon seasons in the more southern and east-ward areas at the Tanzanian coast (Tanga and Zanzibar). Our findings suggest that different seagrass meadows in coastal East Africa exhibit varied influence of the monsoon seasons on the abundances and community compositions of fish larvae. Seasonal variations in fish larvae abundance and community composition in seagrass habitats of coastal East Africa are suggested to be influenced by site-specific hydrodynamics, seasonally driven environmental conditions, adult spawning habits, and fish larvae behavior. Since seagrass meadows harbor various fish larvae families in the pre-settling phase associated to the dominant coastal fishes, management and conservation measures of fish larvae are crucial for sustainable coastal fisheries.Seagrass meadows play a major role in fisheries productivity through nursery function of fish larvae; however, little information is available on the seasonal distribution of fish larvae in seagrass meadows at a large spatial area of East Africa.
