Abstract or Summary
  • The Training Department of the Southeast Asian Fisheries Development Center has completed a wide range of experimental fishing trials on the use of Juvenile and Trash Excluder Devices (JTEDs) over recent years. These trials have investigated the effectiveness of the rigid sorting grid, rectangular window and semi-curved window JTEDs in releasing juveniles of commercially important fish species and trash fish from demersal fish trawling operations. Experimentation began in Thai waters adjacent to the Provinces of Chumpon and Prachuap Kirikhan in 1998. This initial work led to the identification of the rigid sorting grid device as an effective tool in the exclusion of juvenile and trash fish from fish trawls. Further experimentation focusing on the effects of grid spacing on the performance of this JTED was completed in Brunei Darussalam and Vietnam during 2000 and 2001. In September 2001, the rigid sorting grid JTED was the subject of experimental fishing trials in Malaysian waters. This work focused on the effects of grid spacing and day/night influences on JTED performance, highlighting that a grid spacing of 1.2 cm is highly effective in reducing capture of juveniles and trash fish in fishing areas adjacent to the Malaysian Peninsular. JTED performance was also generally greater during day-time fishing trials. More recently, the Training Department has completed trials in the waters of Indonesia and the Philippines. In 2002, results from Indonesia suggested that the rigid sorting grid device with the 4 cm spaced sorting grid achieves the highest releasing rates of juvenile and trash fish in the Arafura Sea region of Eastern Indonesia. In 2003, investigations completed in the Philippines highlighted that the rigid sorting grid device with a grid spacing greater than 1 cm is generally more effective in the exclusion of juvenile and trash fish than the rectangular and semi-curved window JTEDs. During 2004, demonstration and experiments on the use of JTEDs will be completed in Myanmar and Cambodia to provide a complete coverage of relevant SEAFDEC Member countries. Researchers are confident that the above mentioned activities have been effective in developing regional understanding of the use of JTEDs. All work has been completed in close collaboration with the fisheries departments of the Member countries involved in the project. This has been effective in building capacity for regional governments and fisheries personnel to be responsive to the needs of fishers as they move toward the development of more sustainable fish trawl practices.
