So, let’s talk about why the assessment surveys by NOAA research vessel data is corrupt.
So, let’s talk about why the assessment surveys by NOAA research vessel data is corrupt. The research vessel only makes computer generated tows randomly prints the tow log for the assessments to take place. The research vessel goes to those designated sights and makes 20-minute tows then on to the next tow. The fall survey lasted 66 days from start to finish. They were supposed to make 377 tows at 20 minutes a piece the vessel started in Virginia and tow logs were to be made all the way to the Gulf of Maine. Only 308 tows were made in this 66-day assessment. 308 tows were accomplished of the 377 supposed to be towed so only 82% of the survey was completed. If you look at the tow areas, only 30 tows were made in the Gulf of Maine. >click to read<, By Jerry Leeman
Video fish survey simple in concept, challenging in execution
In a multi-media world, conducting fishery stock assessment surveys was stuck in the early 20th century until Dr. Kevin Stokesbury came along.The marine scientist at the UMass School for Marine Science and Technology concluded more than a decade ago that if he could do it using underwater cameras, he could be far more accurate than bottom trawls using questionable net gear in questionable ways. The result is the booming scallop industry, confidently and sustainably fishing thanks to the process of photographing and literally counting the scallops on the ocean floor. They were abundant almost beyond belief. Read the rest here 11:48
