Statistical data for fish landings is collected through the daily returns of sales submitted by middlemen at the Wholesale Fishmarket in Valletta.

The data collected in the Wholesale Market is:

• date,
• fisherman identification,
• voucher number,
• retailer name,
• licence number of the retailer,
• for each species: species name, number of boxes, weights and price.

Statistics on landings and fishing effort are also being collected through a port sampling scheme for vessels under 10 metres in length. A log-book scheme for vessels over 10 metres will be introduced in the near future.
