The hovering pontoon trap: The tougher, younger sibling in the pontoon trap family
Trap nets are a large, stationary, and fixed type of passive fishing gear that has traditionally been used for catching fish in shallow coastal environments. Despite their large size, catches are often retrieved using small boats, making them less energy demanding compared to active gear types. This, along with the stationary nature of the trap, allows for fishing with relatively low environmental impact due to minimal disturbance of the benthic community. The combination of minimal benthic impact, live catch, low fuel, and selectivity offers great potential for the development of sustainable coastal fisheries. Here, we describe the development of the hovering pontoon trap, a fishing gear with a robust design to resist strong waves and currents, and usable in both shallow and deep waters to catch both pelagic and benthic species. We present results from early case studies targeting benthic Baltic Sea species, including perch ( Percha fluventaliis ), Atlantic cod ( Gadus morhua ) and vendace ( Coregonus albula ), showing similar or improved catches in relation to earlier studies. Further, we show that the hovering pontoon trap was able to withstand harsher conditions than previous bottom-set models, making it a possible solution for the targeting of benthic fish communities in coastal environments. • The hovering pontoon trap is an improvement of the traditional pontoon trap. • The trap design protects it from wave and current actions. • The trap has been initially tested on the benthic species cod, perch and vendace with similar or improved catch rates.
