To ask the Secretary of State for Environment, Food and Rural Affairs what the average weight of discards per year per UK fishing vessel has been over the last 10 years. (248984)

UK fisheries laboratories send observers to sea to record the quantity of fish discarded and retained by fishing vessels. This sampling is intended to provide estimates of discards of the main commercial species. It is only possible to sample a small proportion of fishing trips in this way. For this reason the sampling effort tends to be focused on those fisheries which are of relatively large scale, and which usually involve some discarding. There are a large number of fisheries which are small in scale and/or involve little or no discarding, which are not routinely sampled. These include many shellfish fisheries, fisheries for pelagic species such as mackerel and herring, and in particular inshore fisheries involving vessels less than 10 metres in length. Vessels in this latter category form the majority of the UK fishing fleet. As a result, estimates of discards given as weight per vessel may not be representative. Estimates of discards by UK vessels for some important fish stocks are given for 1998 to 2007 (where available), and numbers of fishing vessels registered in the UK over the same period are given in the following tables.
