Video with Over 3.5 Million Views

We have been developing videos for years to keep everyone informed about new products, exciting installations and how to use our equipment.

The below video has more than 3.5 million views. We thought to resend the video for everyone’s enjoyment.

The video shows Notus equipment used on a Danish twin trawler. This was developed in cooperation with a Danish Captain Mads Nielsen. Mads has since passed but this video has been informative to thousands.

Customer Focus: Tuna Seiner

Compagnie Francaise Du Thon Oceanique (CFTO) is based in France and operates a large fleet of tuna seiners. CFTO installed a Notus Seinemaster for real time monitoring of their tuna seine. This video focuses on the vessel and how the Seinemaster is used.

Echo at the International Prawn Forum

This is an excerpt of a larger presentation given by Mr. Nick Edwards at the International Cold Water Prawn Forum in Reykjavik, Iceland. Nick explains how the fleet is using Echo to detect shrimp. The presentation also gives a wonderful introduction to the Jordani shrimp fishery on the US west coast.

Notus Names “Best of Boats & Gear”

Every year, the largest commercial fisheries magazine in the USA, National Fisherman, makes a list of the best new technologies over the past year. Notus is proud to have two new technologies on this year’s list: Echo and Dredgemaster. Short excerpt’s from the original article are below.


National Fisherman excerpt: “A product that employs listening devices attached to the grate in a shrimp trawl. Interestingly enough, shrimp make a specific acoustic signal when they hit the grate, and this feedback can be sent to the pilot house. Measuring the signal allows the captain to calculate catch rates and avoid water tows. Go from fishing blind to fishing a certain number per hour.”


National Fisherman excerpt: “Newfoundland-based Notus introduced Dredgemaster which uses wireless sensors to measure [warp length], pitch and roll angles for improved dredging. With sensors mounted on the tow bar pitch can be adjusted.”

20 Year Notus System

Captain Simon McDowell of the FV Daroni in New Zealand has been using the same Notus system for almost 20 years. They use Catch Sensors to determine when to take back the trawl. On occasion, they even use their sensors to locate a lost trawl (due to the Notus Active Technology).

See an interview with Captain McDowell here compliments of Marintec.

New Dealers in France and USA

Over the last 25 years, Notus has recognized the importance of local support for its net monitoring systems. Local installation and repair by trained/qualified dealers is key. With that in mind, we are proud to announce two new dealers: GCB Marine in the USA and Pochon Pro in France.

Smallest Boat to Fit Notus

The smallest boat ever to fit Notus!

The smallest boat to install Notus is the 9.8 meter trawler Millie-G FH21 owned and operated by Paul Blewett of Camel Fish in Padstow.

Seafield Navigation, the Scottish distributor for Notus fitted the Trawlmaster. Fran West, owner of Seafield, comments: “The challenge with boats this size has been maintaining the balance in these small doors. Larger heavy sensors upset the door behavior by adding drag and toppling the doors.”


Millie GNotus sensors weigh just 1 kg in water which means that they do not add extra drag or unnecessary weight to the doors.

The Millie-G uses 4 1/2 foot Dunbar doors on a light single bottom trawl, and midwater doors/trawl for seasonal pelagic fishing. Working in water as shallow as 5 or 6 fathoms with wire lengths out to 175 fathoms meant an innovative approach was needed. On the doors, the Millie G monitors doorspread, wire length and door angle. Also door depth is used on the midwater gear to ensure the optimal door attitude.

The addition of Headline Height and Footrope sensors give: net opening, distance to the bottom and footgear clearance. While the catch sensor allows early detection of a good catch or an early warning of a bag of jellyfish which prove very difficult to handle on boats of this size.

Notus ‘s past experience with high length/depth scope ratios proved invaluable in getting the hydrophone installation right the first time. Nick Plant at NJP welders made an excellent job of forming the hydrophone into the glass fiber hull.

After initial shakedown sea trials, the rapid 5 second updates from the Notus system removed the guesswork from the job. The headline height was found to agree with the netmakers design and the doorspreads are responsive to the changing water depths and bottom conditions including snag detection.

Interview With Captain in New Zealand

The below video is a perfect example of how Notus can contribute to the overall fishing operation. The video was created by Marintec, the Notus distributor in New Zealand. This is mainly an interview with Captain Ant Smith of the FV Donna Maria out of Port Chalmers, New Zealand. Many thanks to Captain Smith and Marintec for sharing their knowledge!
