Annual Report 2015
In this fifth CRISP year the process of developing new knowledge, new fishing gears and instruments for the fishing fleet as important tools for making the trawl and purse seine fisheries more sustainable has continued. These achievements have only been possible because of extensive cooperation between the centre’s industry partners and research institutes.
Both the fishing industry and research institutes need more accurate density and abundance measurements of schooling fish species than what is possible with current instrumentation. Simrad is collaborating with IMR for developing new and improved fishery sonars which can quantify the size of a school prior to shooting the purse seine, and high definition echo sounders which may accurately measure the fish size. Most of the problems anticipated in the calibration of both systems are now solved and was published in 2015. Simrad has recently released the wideband echo sounder EK80 as a new product, and is working on finalizing a new sonar which is meant to work inside the purse seine with one to three inspection beams for sizing of fish.
This is just some of the work that took place on 2015. For the full picture:
