Underwater exploration and Japanese fish discoveries

Underwater Exploration

A short and exciting tour to explore the life underwater and introduce you to typical Japanese fish in their natural habitat.

Blacktip grouper(Akahata)

Blacktip groupers prefer to live around reefs and big rocks, at a depth of 5 to 80 meters and feed mainly on small fish and crustaceans.
Up until now in Japan, these fish were mostly found along the Pacific coastline south of Tokyo, but these days, their habitat tends to move northward gradually. As it is particularly difficult to find any grouper with a Fish Finder, the best way to find them is to locate their habitat, rugged terrain and large rocks, using the “Bottom discrimination” function. Blacktip groupers don't swim in school, but if one of these fish is in the area, then we can deduce that there are other Groupers nearby. In addition, as shown in the video, other fish species such as the “Japanese Stingfish” live in the same areas as the Blacktip grouper. While “Japanese Stingfish” stay close to the seabed, Blacktip groupers tend to rise 2 to 3 meters above the seabed to capture their prey. A single echo will therefore appear on the fish finder.
