In light of the results, it is predicted that the population of sea trout is more affected by sea lice than previously claimed. The trap presented in this study should be a useful complement to the existing set of tools used for monitoring sea lice infestation levels in sea trout and other salmonids. It is recommended that the trap design be considered a preferred method for sea lice infestation studies in the future. Furthermore, although the trap was designed to catch sea trout,other coastal fish were also caught. The trap is thus an appropriate tool for studies when live coastal fish are required for laboratory experiments, procurement of good-quality samples of fish scales,experimental studies in the field, tag and recapture studies and for
the capture of fish for conservation purposes.
