Research and Sampling
This might be the most important  statement you , as a Research Scientist, might read.
INS has an assortment of Sampling Gears that No One else designs or builds. We use netting that is far superior to nylon and most polyethylene  material. INS has  gear that "does tricks" in the water, to allow even the smallest hp vessels to take samples of their target species with bare minumum effort.


Most of our customers do not have large boats, large crews or large budgets. They want to sample or monitor fish or other marine life and do it with "easy to use" gears  built exclusively for smaller hp vessels. THIS is our forte'.



The "Bigger-is-Better" syndrome.

All too often I hear or see, these 200' ships with  20 Fathom Head Rope Trawls and 300 kg  steel doors . . .  all outfitted to take samples of Midwater or Benthic fishes.  They haul up 2-3 tons of catch every few hours and sub-sample 10 kg or less for the lab.  The rest is shoveled over.


The only reason I can see is that some agencies feel there is no other way around this sampling except to use commercial trawls. But what if your requirements only call for small samples? Why kill so much to sample so few?

There are lighter/ more compact gears developed that require much smaller boats, smaller crews and much less hp to sample the same waters and the same fish.
Ask us.




 " WE ALWAYS USED THIS BEFORE, SO WE CAN'T CHANGE NOW "  syndrome.

Yes, we understand the dilemma . . . 20 years of using the same old designed heavy, water logged net to sample in rivers, lakes, streams or lakes. Consistentcy is what you're after in your data. 

But what IF  we could show you how to correlate what youre using with gear that catches the same species and size of fish, but does it with more ease and  doesn't  require as large of a boat or set-up? What if you never had to re-coat a net again? What if your sampling nets weighed less, took up less space and were substantially stronger than what you currently use?


Interested in any of this?  Give us a chance to work something out for you.
Welcome to the Star-Trek era and put that old Fred and Barney Flintstone gear in the shed.
