Temperature Directed Fishing: How to Reduce Bycatch and Increase Productivity

Fishermen can reduce search time, increase fishing productivity, and eliminate bycatch by using the temperature directed fishing methods taught in this book. TDF requires minimal equipment--a notebook, graph paper, and temperature sensors to measure surface water temperature and subsurface temperature. TDF methods are widely practiced in Norway and by most of the larger Japanese fishing operations, and for them it pays off in high productivity.
