12. How to determine the coastal topography and distribution of coastal resources

The topography of the coast and seabed of the target area, as well as the nature of the seabed and the depth of the coastal waters, are indicated on the nautical charts covering the target area. Based on this information, fishermen who have been fishing an area for many years are interviewed to find out which fish species they catch, in which season and area, the distribution of fish species and seasonal fluctuations in catches, the quantity of fish caught, and the evolution of the length of the fish caught from the past to the present. The knowledge of fishermen who have been fishing in the area for many years often provides accurate and valuable information based on on-site perception.
