How is artificial lighting affecting the catches in deep water rose shrimp trawl fishery of the Central Mediterranean Sea?

The effect of artificial lights mounted on the headrope trawl net on the catch of deep water rose shrimp (Parapenaeus longirostris), European hake (Merluccius merluccius), and Atlantic horse mackerel (Trachurus trachurus) was tested in a survey carried out on-board a commercial trawler off the SW Si...

Zusammenfassung:The effect of artificial lights mounted on the headrope trawl net on the catch of deep water rose shrimp (Parapenaeus longirostris), European hake (Merluccius merluccius), and Atlantic horse mackerel (Trachurus trachurus) was tested in a survey carried out on-board a commercial trawler off the SW Sicilian coast. A total of 18 repeated nocturnal hauls, alternating without (control) and with (test) LED lights (10 green and 10 white) according to the fishers’ setup, were conducted. Overall, the test net catch rates were not significantly higher than those of the control net (Kruskal-Wallis test, p > 0.05), except for P. longirostris (p
