Benefits to Fishermen and Oceans

The Eliminator - Benefits to Fishermen and Oceans

F/V  Iron Horse, one of the vessels used to conduct side-by-side comparison hauls
  • Hauling in less bycatch improves work productivity, with a three-fold reduction in sorting time on deck.
  • The design of the four-seam net provides opportunities for longer tows and cleaner fish, as the haddock are not damaged by the bycatch of spiny marine animals.
  • The trawl’s early release of nontarget marine life reduces their risk of experiencing damage or mortality.
  • Longer tows allow fishermen to minimize hauling and setting, so fishing time is more efficient.
  • Field tests indicate the catch falls within the possession limit guidelines for the Regular B-Days-At-Sea program, permitting fishermen additional time to selectively fish for haddock.
  • The 24-inch (60 cm) spacing of the large discs on the rockhopper sweep provides room for bottom fish to avoid capture.
  • The design of the rockhopper makes it lighter than current nets, so the gear has less contact on, and does less damage to, the seabed.
  • Cod bycatch was significantly reduced in the field tests, while flounder and skate bycatch was virtually eliminated.

The Traffic Cone - Benefits to Fishermen and Oceans

Black-browed albatross and imperial cormorants (or blue-eyed shags) on New Island, Falkland Islands.
  • The Traffic Cone is a simple and cost-effective device that requires minimal time and resources to implement.
  • It is a mitigation device that may help fishermen comply with international conservation agreements such as the Agreement on the Conservation of Albatrosses and Petrels.
  • At a time when seabirds are threatened at a higher rate globally than all other species-groups of birds, reducing seabird injuries and fatalities due to bycatch could result in critical population growth over time.
  • Responsible fishing practices help protect seabirds, whose natural adaptations require them to live and feed off the sea.

Nested Cylinder - Benefits to Fishermen and Oceans

Shrimping Boat, Dry Tortugas National Park.
  • The reduction in bycatch that could be achieved through use of the Nested Cylinder device may result in a significant drop in trawl sorting time.
  • Increased net retention of target species would result in a smoother and faster operation, saving fishermen on fuel costs.
  • As a result of reduced sorting time on deck, the quality of the target species may improve to a "cleaner" product - which could generate a higher profit margin.
  • Reducing bycatch of juvenile red snapper promises a chance for the stock in the region to rebuild.
  • Fishing vessels with improved operational efficiencies that spend less time at sea, may reduce marine pollution from boat emissions and leaks.

Passive Porpoise Deterrent - Benefits to Fishermen and Oceans

Bottle-nosed dolphin, Bahía Islands, Honduras.
  • The Passive Porpoise Deterrent is cost-effective: a one-kilometer stretch of fishing net could be equipped with two hundred passive devices at a total cost of US$200.
  • Because the reflectors are similar to existing fishing floats in construction and durability, they also could be used as float replacements.
  • Widespread use of the device could support less expensive regulatory compliance with the Harbor Porpoise Take Reduction Plan (U.S.) and Council Regulation (E.C.) 812/2004 to mitigate incidental catches of cetaceans by fishing vessels.
  • The low-cost, simple design results in more attainable implementation for fishermen in developed and developing countries.
  • Fewer pingers are needed when they are used in combination with the passive reflector devices, potentially reducing noise pollution in the marine environment.
  • Implementation of the Passive Porpoise Deterrent may significantly reduce bycatch of harbor porpoises.
