This cruise survey was conducted for the trawl monitor system (SCANMAR) sea trial and experiments on the comparative efficiency and impact of Vee type and Rectangular otter board for trawl fishing operations. To compare the catch Per Unit Effort (CPUE) and efficiency between both otter boards, the recorded data included as following:

- Fishes species sampling: bottom otter board trawl

- Water quality: CTD

- Net opening and Net spread: SCANMAR

- The depth of otter board: SENSUS depth recorder

- Otter board underwater observation: GoPro camera

The cruise survey was scheduled from 3 to 9 April 2023. Respecting cruise order M.V. PLALUNG Cruise No. 5-1/2023, seventeen (17) operations for bottom trawl for fisheries resources and benthic marine debris and ten (10) CTD portable were conducted.
