Echo Detects Red Shrimp in the Mediterranean
(CANADA, 10/7/2020)
Norwegian Lobster (Nephrops Norvegicus) and Red Shrimp (Aristeous Antennatus) are some of the most valuable species caught by the Spanish fleet, both in the Atlantic and in the Mediterranean. The carbon footprint is more intense than small pelagics. Therefore, fuel saving technology is very important to the fishing operations.
One of the biggest problems in the fishery is Red Shrimp cannot be detected with shipboard or trawl sounders. The Captain has no idea where they are actually catching. Notus Electronics Ltd.has developed Echo to respond to the need to detect Shrimp, Red Shrimp and Norwegian Lobster. The Captain knows, in real time, if there is a sufficiently profitable amount of the target species in the area where they are trawling. Or if, on the contrary, its presence is so scarce that it is not worthwhile to continue trawling. This significantly reduces fuel consumption.
Red Shrimp Hitting Pickup and Echo Sensor.
Initially developed for the shrimp fishery on the US West Coast, Echo has been introduced with increasing success in Nephrop fisheries. Echo listens for the sound of Red Shrimp hitting a pickup device. This data is transmitted to the vessel in real-time.
Determining the optimal sensitivity for Red Shrimpwas an important goal of this first installation.Preliminary results have been highly satisfactory. Operational efficiency is substantially improved in real time by confirming the presence or absence of Red Shrimp during trawling. High catch rateshave been achieved when Echo detected higher concentrations of Red Shrimp and the vessel turned around to target these concentrations. Catch rates doubled compared to vessels without Echo.
