Mariculture in Kenya today serves as a means by which the coastal population is able to secure its subsistence and its commercial welfare. As a pathway to the increasingly touted Blue Growth, Mariculture is more and more being acknowledged by the government as a vehicle through which transformational socio-economic development can be achieved. Common mariculture practices in coastal Kenya are fin-fish farming, shellfish farming, as well as Crab and Seaweed farming. Policy frameworks, both local and global, are in place to encourage the growth of mariculture as an integral sub-sector of the larger fisheries sector. While financial gains (and the associated benefits) from coastal mariculture activities have been realized, structural short-comings in both policy and practice have not allowed for its full potential to be achieved. Although the human and natural capital necessary for mariculture in Kenya to thrive abound, financial and built capital have not kept pace; this together with unreliable access to markets continue to stifle the sub-sector’s growth. An overview of the current state of the sub-sector is presented, as are recommendations necessary for it to flourish and provide more locals with incomes for their survival.
