Testing the Installation of Camera Recorder GoPro Hero 3 to Observe the Fishes Escapement from Codend of Trawl Net in Trawling Operation
Abstract
The Testing the Installation of Camera Recorder GoPro Hero 3® to observe the Fishes Escapement from Codend of Trawl Net in Trawling Operation was conducted in with Fisheries Research Vessel Pramong No.16 of Eastern Marine Fisheries Research and Development Center, department of Fisheries (EMDEC-DOF) at Rayong Province, 19-24 November 2014. Testing was supported by the FAO/GEF Project Strategies for Trawl Fisheries By catch Management (REBYC-II CTI) through the collaborative efforts of SEAFDEC/TD and EMDEC-DOF, the testing aimed to investigate the applicable of camera recorder GoPro Hero3® with underwater housing and observed on fishes escape from the codend in trawl selectivity experiment.
The results of the survey presented that camera recorder GoPro Hero3® with underwater housing possible to install with codend of trawl net to observe on fishes escape from the codend in trawl selectivity experiment. Limitation of battery capacity, maximum depth of underwater housing, underwater visibility found major hindrance. The best recording on fishes escape from the codend in trawl selectivity experiment can record by the position of camera recorder that installed at outer side of codend at range 1 m from rear part of condend. Camera recorder was head-up set and faced to rear part of codend. Practices on the underwater camera installation should be regularly done with several set of camera recorder in every trawl fishing operation.
