In 2021, Shipboard Training I will include a hands-on training voyage on biological sampling and fish counting, which are the basis of fisheries surveys. Students will learn how to survey and describe species composition and size composition by sampling organisms using net sampling gear such as mid-water trawls and MOHTs, as well as fishing. In addition, students will learn how to quantify the distribution of dominant species by measuring fish assemblages using a quantitative echo sounder and scanning sonar.

In 2021, Shipboard Training Ⅱ will include a training voyage on the marine environment. The main focus will be on understanding the structure of the ocean and its relationship to primary production using water temperature, salinity, pressure, dissolved oxygen, and chlorophyll fluorescence acquired by a water temperature, salinity, and depth meter called a CTD (sensor installed at the bottom of the frame in the photo). In addition, water samples will be taken from bottles installed at the top of the photo for more accurate dissolved oxygen measurements and other measurements will be taken on board.
