Sea lamprey found in the northern and western Atlantic Ocean along the shores of Europe and North America, in the western Mediterranean Sea, the Black Sea, and in the shores of the Great Lakes. They have been found at depths to 4000 m and tolerate temperatures between 1.0 and 20 °C. The largest European populations of sea lampreys are located throughout the south-western areas of Europe (north-central Portugal, north-northwest of Spain, and west–south-west of France). These countries also support the main fisheries of the species. Sea lampreys are anadromous. From their lake or sea habitats, they migrate up rivers to spawn (followed
Asia-Africa Growth Corridor complemented by digital connectivity, which would undertake the realization of the idea of creating free and open Indo-Pacific Region. The AAGC will give priority to development projects in health and pharmaceuticals, agriculture and agro-processing, disaster management and skill enhancement. The connectivity aspects of the AAGC will be supplemented with quality infrastructure. Unlike OBOR, now BRI (Belt and Road Initiative), which entails development of both land corridor (new economic belt) and ocean (marine silk road), AAGC will essentially be a sea corridor linking Africa with India and other countries of South-East Asia and Oceania by rediscovering ancient sea-routes and creating new
