2009 - 2011 Centre for Environment, Fisheries & Aquaculture Science (Cefas) North Sea Whitefish 2012/13 - Fisheries Science Partnership

One of a time-series to develop a North Sea survey to compare the catch rate of our whitefish species using an otter trawl on hard grounds and a scraper trawl on soft grounds. Detailed measurements will be made of cod, whiting, haddock and possibly plaice.本数据集为用于开展北海调查的时序数据集系列之一，旨在对比使用拖板拖网（otter trawl）在硬质海底与刮铲式拖网（scraper trawl）在软质海底时，目标白肉鱼类的捕获率。本次调查将针对鳕鱼（cod）、牙鳕（whiting）、黑线鳕（haddock）以及潜在的欧鲽（plaice）开展详细测量工作。
