The idea is to incorporate (if possible) a catch monitoring function into the

nets are in or out, and whether their nets are full or empty.

================================================== ========

You might be able to do something fairly simple if you have decent
upload bandwidth. Consider an internet enabled camera with imbedded
software and IP functionality (readily available for reasonable $$$s).

It could be pointed at the back deck and do a periodic upload of a
picture along with the data stream. Most fishing boats in this
countrykeep the back deck brightly lit even in the middle of the
night.

And if the lights do go out, you know there is something fishy going
on. :-)

Consider adding the camera even if the bandwidth is not really there,
visual deterrent as they say.
