A new web based electronic system for the recording of sales of fish in Ireland has been developed. It is now a requirement that all, auction centres and buyers of first sale fish be registered under the terms of this regime, and submit sales notes electronically within 48 hours of the first sale of fish. Sales notes detail the size, weight, price and date of first sale fish, as well as information about the seller and vessel of origin. In keeping with the Governments policy of developing Ireland's knowledge economy, this web based system was designed and commissioned to accommodate the registration and the subsequent submission of sales notes via the web portal www.fishingnet.ie. Buyers now have to register via www.fishingnet.ie and have to complete sales notes using a secure username and password on www.fishingnet.ie. This system compliments the requirement on masters of fishing vessels to complete standard log books and landing declarations. The log-book records what type of species of fish was caught, which area there were caught in, when they were caught, the quantity caught, and the method used to catch them. Cross-referencing sales notes with landings data i.e. logbooks (as mentioned above), improves the monitoring and control of fish landings into Ireland, and the traceability of that fish.
