Because it is found in almost all parts of the study area except Nosy Ankao. Traditional shrimp fishing requires the use of a landing net as fishing gear (Figure 13(a)) and is done on foot.

This night fishing (magnilo) consists of searching for shrimp (Figure 13(b) and Figure 13(c)) which feed on the mud using traditional techniques (fishing on foot).
