This channel just gets better and better. Bravo!

make a video whow to ring a net ,if possible .

Thanks for the request - happy to tailor it to specific deployment methods/target species

0:50 is not right picture. E=0,7 for central image E 0,3(or0,5) for image on the left And image on the right the net hanging on E= 0,9 ))

Hi! Thanks for your comment - hanging ratio is calculated by the length of the headrope divided by the stretched length of the mesh, using the same units for both. In this example, I have kept the length of the headrope as '1 meter' for all three examples. Therefore for the first image, dividing 1 meter by 1.4 meters gives a hanging ratio of 0.7 (unitless). This is repeated for all three examples, so 1/2 is 0.5 and 1/3 is 0.3...

@@oceans_explained коэффициент вы определяете правильно. Но ваши изображения не соответствуют значению коэффициента, При E=0,7 (0,71) форма ячейки стремится к квадрату, всё по теореме Пифагора. Этому соответствует изображение в центре. При E=0 сеть не имеет длины. При E=1 сеть не имеет высоты.
