The Programme from June 2008 to March 2009 was part-funded by a grant from Yorkshire Forward.

Trip logsheets, designed and formatted by the EEFPO and Cefas, were distributed to all fishers in the project. The logsheets include fields for: • Target species, gear type and dimensions (including mesh size), and quota allocation. • Date, time, a single midpoint lat/long identifier for each tow/haul, target species, hours towed/soak-time. • For each of the three objectives (1-year-old cod, 2-year-old cod, and cod of all ages): a relative estimate by the observing fisher of abundance using a 5-point scale (0 = zero, 1 = small numbers, 2 = moderate numbers, 3 = high numbers, 4 = very high numbers), and an estimate of the quantity (by weight and number) retained and discarded. Fishers were requested to estimate relative abundance using their previous historical knowledge of incoming year classes and of cod fishing in general (the average fishing experience of participating skippers is 30 years). Fishers were provided with guidance by quarter on the expected upper and lower likely lengths of 1- and 2-year-old cod, derived from previous sampling of retained and discarded catches during recent fishing trips attended by observers in the central North Sea. No allowance was made for potential differences in growth rate between different areas of the North Sea, as this was deemed appropriate in order to reduce the complexity of sampling by fishers moving in and out of different fishing areas. Also, no allowance is made for difference in growth rate at age between years. Fishers were provided with fish measuring boards, and guidance was given in the subsampling of large or mixed catches. The distribution and collection of logsheets and the transfer of data onto Excel spreadsheets were carried out by the EEFPO. Fishers were encouraged also to record additional observations they considered relevant to the project. MEDIN 3.1.1
