This is Fish Radio. I’m Stephanie Mangini. What do nets do underwater? A net monitoring system can tell you that. More after this…

Is my seine around the fish? Is my net getting tore up on the bottom? These are just a few things fishermen worry about when it comes to their nets. With an advanced net monitoring system from Notus Electronics the stress of what your net is doing is no longer an issue.
 
“Our Seinemaster is a wireless monitoring system.  We install a hydrophone in the haul of the ship and then we communicate wirelessly to sensors on the net.”
 
Francis Parrot is the marketing manager for Notus.  They have been making sensors for commercial fishing gear since 1992. Their top customers are mid water and bottom trawlers, seiners, and their newest sensor line for scallop dredgers.
 
“Connected to the hydrophone in the haul is a pc. The computer is used for display and logging information. You see a numeric display of the lead line depth and the lead line sink rate, and you also see a graphic display.” 
 
The sensors show a nets depth, cork and lead line alignment, and temperature. It helps to keep nets from getting torn up along the bottom and can also tell when your seine is around the fish.
 
“You can insure you are around the fish before you purse. So you basically look at your sonar and you realize that the fish are at 18 fathoms, and you want to be sure that that seine is at least at 18 fathoms before you close it, well that’s where the Seinemaster comes in. It will give you the exact depth of the lead line.”
 
Their sensors are used worldwide; Francis says that their system is fairly new in Alaska and about a handful of boats using them; but he says in Spain you can’t find a boat that fishes without it.
 
“No matter if it’s a 36ft boat or a 150ft tuna seiner, everyone uses these sensors for seining they have become that important for the industry.”  
 
Francis says that fishermen 20 years in the industry are blown away by what the system has to offer.
 
“One gentleman said he learned more about how the seine fell and sank in the first six weeks using the system then he had in the last 20 years.”
 
The Seinemaster runs between 14 to 15 thousand dollars, but the knowledge that comes with it, Francis says is priceless.
 
“If you can catch more fish and you can reduce the tear ups on the bottom; that’s two large benefits to any operation. It’s a pretty quick return on investments for the Seinemaster or the Trawlmaster.”
