Fig 3. Malta annual Ċerna catch landings data (kg) between 1947 and 2009.

Results show a decreasing trend in catch landing of Maltese Ċerna (kg) over this time period. An estimate based on catch landings from the 1940s (mean 11,583 kg year^-1) and the 2000s (mean 982 kg year^-1) show a decrease in catch landings of 92% over the last 62 years. An assessment of catch landings based on the trend line (polynomial, order 2) estimates a decline of 99% between 1947 and 2009. Outlier data (0 kg year^-1 reported) are excluded from the chart and estimates.
