Below you will find links and videos highlighting the current manufacturers of several different styles of this innovative gear. Not all of the gear videos are the most current, as some of the designs are protected under non-disclosure agreements with the author or patents pending. As newer videos become available, this page will be updated. I have also included links to contact the manufacturers directly under each video.
The systems are presented in alphabetical order. Feel free to contact the author for any questions.
The majority of baleen whales feed by either opening their mouths after targeting a specific prey and taking in a large amount of fish plus sea water, then forcing the excess water out through their baleen, or by actively swimming with their mouths open while straining the water. The latter is the method of feeding used by the North Atlantic Right Whale.
While entanglement is not limited to this species, they do tend to pick up a great deal of vertical line from the water column. With eyes placed on the sides of their heads, these whales have limited vision directly in front of them, similar to horses. Lastly, North Atlantic Right Whales have an unusual downward angled curve to the back of their lips, creating the perfect anchor space for any rope they may accidentally sweep up in their search for food.
Other causes of entanglement:
Seine nets, monofilament nets and lines, and mooring lines are just a few of the underwater threats faced by dolphins, porpoises, sea turtles, sharks, and pinnipeds (seals, sea lions) as well as a whole host of whales, both large and small.
Tora Johnson’s exhaustive look at the issue of cetacean entanglement and fisheries management is just as accurate and relevant today as it was when she first began her research. While some of the players have changed, the issue remains largely unresolved. Her insights lend remarkable depth and understanding to anyone wishing to navigate the complexities of change within our vital coastal communities.

As consumer demand for sustainably produced food grows, industry, too, will need to be directly involved in the hands-on adaptation of techniques that ensure profitability as well as workforce compliance with policy.
During my recent study abroad in Ireland, I was witness to the pride and commitment the fishing industry had toward sustainable practices, as well as in maintaining their strong cultural identities. Understanding how that balance is achieved is critical to formulating a best-practices approach to implementation of new technologies in the United States, which has been struggling in its efforts to adopt new methods. With multilevel-multi-agency policies now being implemented that limit fisheries acceptable biological catch, innovative approaches to harvesting fish from the sea has become a necessity. Policy adaptation supporting advanced fishing technologies which are designed to reduce bycatch and entanglements can cripple industry if too restrictive and must be adopted in ways that are manageable and fair for success to be realized. Lobbyists, scientists, and industry in the US are now resorting to a variety of litigious measures to protect their stated interests, therefore, understanding how the EU cooperatively manages their fishing industry could prove highly beneficial. Policy measures that ensure solicitation from all stakeholders will be examined, and future suggestions for a novel framework for the US managed fisheries will be proposed. My study will focus on those policies and directives in the EU identified to have had the most positive impact on fishermen and their communities. This research is instrumental in assisting with efforts in the US when interacting with community fisheries to encourage a more fruitful and engaged cooperative attitude toward marine conservation.
Past research has indicated an undeniable benefit to the use of innovative ropeless gear within pot and trap fisheries with a removal of end lines and buoy lines. (Baumgartner et al., 2018.; Werner et al., 2015; Lent, 2017; FAO, 2018) These innovative approaches to end line management allow for the lowered risk of bycatch and entanglements of critically endangered species, most particularly that of the North Atlantic Right Whale.
It is imperative that a better understanding of the benefits and potential gains be attained if technology such as this is to be affordable and accepted for widespread use for pot/trap fisheries. Due the innate differences of individual fisheries, it is well accepted that there will likely not exist one perfect ropeless technology that will address all of the individual needs of all fisheries. Many of the current designs have several decades of successful use in other applications, serving to catalyze and invigorate new manufacturers of gear, as well as thoughtful adaptations of existing devices.
As with any proposed change to fishing technique or technology, there has historically been a period of resistance, research, and adjustment. This period has been unusually long for ropeless gear, and thus far, much of the discourse between management and industry partners has been laden with untested hypothetical concerns regarding functionality and implementation.
Valid concerns provided by fishers with decades of harvesting experience have not been reasonably resolved with the limited testing that has been completed by manufacturers, environmental non-government organizations, or fisheries partners. To ensure the continued success of a co-management approach to fisheries practices, priority needs to be given to further this testing.

Civic engagement and communication are the most vital link to understanding those factors that drive successful policy change. Immersing oneself in local cultural activities can work to promote the position of all scientists working in marine conservation. Cerebral comprehension of issues that concern fishing communities when faced with change is not enough to inform decision makers, instead, having a “finger on the pulse” of that which makes a community strong is. Often, understanding comes from rapport that develops through identifying shared interests and commonalities.
Spending quality time with those lives you will affect through suggested policy changes ensures that you have the opportunity to not only study the economic impacts these policies can and do have on these communities, but also the cultural implications and experiences that are realized.
