Fishing activity is situated at the vertex between economic and natural activity. So the profitability equation must be kept within the context of sustainable fisheries. To achieve this delicate balance, it is necessary to optimize trawling nets by reducing fuel consumption on the one hand and at the same time obtaining the maximum catch of the target species of the appropriate size.

TRAWL VISION software is in a continuous process of improvement and makes an invaluable contribution to the optimization of trawl nets. Although I knew for a long time the existence of more rudimentary versions of TRAWL VISION, I have been using it since 2019 when the software was provided by the company SAN ARAWA S.A. / ESTREMAR S.A. to the Tierra del Fuego Regional Faculty, of the NATIONAL TECHNOLOGICAL UNIVERSITY with the dual purpose of using it both for educational purposes for students and to carry out scientific work aimed at determining the selectivity of the trawl nets involved in the haki fishery.

The design parameters can be integrated interactively by using the trawl net design module with the simulation module once the equipment is rigged. In TRAWL DESIGNER (TD) I found a powerful design tool, user-friendly and intuitive to use, very useful both for net fishermen and for research work on the behavior of towed fishing gear and even in selectivity work determining the number of optimal meshes to achieve a mesh opening coefficient related to the perimeter of the first catch of the species. Also, it has proven to be a very precise tool to correlate the theoretical results of the software with the results observed in sea trials on those ships equipped with SCANMAR and ISYM SCANTRAWL sensors.

The TVD streamlines the design of any type of trawl, allowing you to make your own designs and verify and correct defects. For existing models, it allows modifying them, adapting them to the specific needs of each ship.


The TRAWL VISION SIMULATOR (TVS) software allows you to observe on screen the simulation of the configuration adopted by the equipment for a specific rig and what is the effect and reaction of the dynamic parameters of the fishing gear, such as vertical opening, opening between tips of fishing gear. wings and between doors thus achieving the best performance for that design. The program also delivers the resistance values ​​generated by the net and by the entire rig in the desired speed range.

The UMLOBI is doing very well and we are impressed with the new trawl based on the design changes that were made.  I cannot, due to company confidentiality,  divulge the average catch performance but it is good.   I am considering an additional workshop to address the trawls of the BORONIA and BLUEBELL ( the other two freezers)  as well and even the F-Class wet fish vessels. Alternatively we may consider to have you build/design a trawl for us based on your experience and design software. Hopefully I’ll get approval to proceed with either or both proposals. It would be great to have you visit us again in any case.

Until then take care and all the best.

Yours sincerely

"Excellent, very didactic to explain the benefits of this excellent software from AcruxSoft. The Trawl Designer that facilitates the creation of any type of trawl net, look for designs to adapt them to their own and modify them, verify defects in plans of different designers, facilitate the work of rederos, extremely useful for teaching in fishing schools or centers of training. The TVS tells the Fishing Captain how his equipment works, what problems the rig has, the ability to change parameters, etc. Both the TD and the TVS are the best tool for any fishing company that will facilitate the work of their captains and rederos improving the work of the ships, saving energy and time ...

We have been developing with a company some pretty good software, it is a company based in Uruguay. It is real time, so you can change any parameters (doors, warp & bridle length, floats, ground rope, speed, you can set door spread to mirror what the vessels are actually getting) any time and it shows up straight away in the simulation. It has proved to be a very accurate tool

As soon as I do I will come back to you with my thoughts.

So far it looks very good and very easy to use

“ Acruxsoft programs TVS and TVD It's easy to use.  only you must release the use and to the Greek language in order to be more understandable terminologies. As a result we can make good use of all the possibilities.

 In Greece we don’t  have fisheries schools. It will definitely be the best teaching tool.

 Can a young fisherman to understand much more easily and more quickly how to make a net and how it works in the water. it’s be able to communicate with other fisheries systems . You can easily build a net and modifications and to see how it works in the water. No need to waste time to find out what happened and what is the problem.  As a result of these better fisheries and protecting marine life.

We love Greece and  our seas and always use technological means for fisheries which will protect our maritime assets. And the Acruxsoft  programs can do right nets and putting the right targets.

with Acruxsoft  programs  we can  apply the new measures of fisheries policy of the European Union.


 We can make a prediction  We can calculate the results  of the net before thrown to the sea the Acruxsoft  associates are constantly available to deal any use  problem of the program with the fisherman. And thank you  Mr Frank Chalkling for this .

 We are third generation fisherman and  something like that we haven't found on our job.

 “ Thanks to TVD and TVS from Acrfuxsoft our company Crimond Industrial Marine in Nova Scotia Canada, is winning contracts over the competition.


We have used this powerful tool of simulation to predict very accurate how the gear is going to react to the changes in it’s rigging.

Most important we have proved our customers the saving in fuel they will get by using different types of netting  ( like dynemix), using the TVS. This tool have put us way ahead of our competition and have been very useful to determine the right prototype of trawl before we even go to the Flume tank in Newfoundland for testing.


We are very please with the performance of both, TVD and TVS. Thank you Acruxsoft for making our business very profitable and up today with technology.”

Although I am not so involved with the design of fishing gear, as a software and technology enthusiast, I must congratulate you for the piece you have built. I must admit that at the beginning I had my reservations about the investment in soft, but seeing this new version, the level of development, implementation and multiple fields of application (industry, education, etc.), I must say that it is a very satisfactory.

On the other hand, with your unconditional support and support I believe that it becomes a real jewel in permanent improvement.

My congratulations and hopefully it will be productive for everyone.

Kind regards.
