Trawling
Hansen Develops Efficient Factory Trawler
50m Factory Trawler sets the standard in efficiency and fish processing capacity. The Danish Naval Design and Marine Consultancy Knud E. Hansen A/S has developed a highly efficient 50 meter factory trawler with a focus on operating efficiency and maximised catch processing facilities. The design delivers excellent fuel economy, reduced environmental impact, and the flexibility to be operated as a single or pair trawler. Fishery Fishing is well known to be an environmentally sustainable method of food production. Greenhouse gas emissions are far lower than the equivalent land-based meat production. Trawling Even though trawling has been regarded as destructive and high oil consuming, it is a fact that pelagic trawling together with purse seine is the most sustainable way of catching fish measured by energy consumption and emission of greenhouse gasses per unit catch. Through the use of new technology pelagic trawls can also operate close to the bottom catching “ground-fish” without damaging the sea bed. In addition, pelagic trawling has a low rate of unwanted by-catch compared to other fishing methods. Trawling does therefore have a future as a sustainable way of producing food. Size of trawler Standards of safety, working- and living conditions together with the desire to allow reasonable space for processing catch on board have led to an optimal ship length of at least 50 metres
Wesmar Introduces New Catch Sensors
