John Wnek of New Jersey on the Responsible Use of Crab Pots

John Wnek, a figure in New Jersey’s environmental studies, spearheaded several impactful research projects. His work, highlighted in the CRABB final report, sheds light on common misconceptions surrounding crabbing practices. In the following article, John Wnek delves into crucial topics: the responsible utilization of crab pots in New Jersey, the imperative of regulatory comprehension, and the disparities in information that significantly influence recreational crabbing practices.

Crabbing is a cherished tradition in New Jersey, offering both recreational enjoyment and commercial opportunities. However, with the popularity of crab pots, there arises the responsibility to ensure sustainable practices that protect both the target species, blue crabs (Callinectes sapidus), and the environment.

John Wnek Discusses the Regulations on the Use of Crab Pots

In New Jersey, crabbing enthusiasts and professionals use various methods to catch blue crabs. Traditional methods include collapsible cages, baskets, and drop lines. However, crab pots, also known as “Maryland Traps” or “overnight traps,” have gained popularity due to their efficiency and higher catch rates. John Wnek of New Jersey explains that these pots are left in the water for extended periods, increasing the likelihood of catching crabs but also raising concerns about bycatch and environmental impact.

New Jersey has specific regulations to ensure the sustainable use of crab pots. For instance, there is a minimum size requirement for blue crabs: 4.5 inches from point to point for recreational crabbing and 4.75 inches for commercial crabbing. Additionally, pots must include a 2-inch cull ring and a biodegradable panel to minimize long-term environmental impact.

John Wnek reports that one critical regulation involves the use of Bycatch Reduction Devices (BRDs). BRDs are designed to reduce the incidental capture of non-target species, particularly diamondback terrapins, which are prone to getting trapped in crab pots and drowning. In New Jersey, any crab pot fished in water 150 feet or less from the shoreline at mean low water must be equipped with BRDs.

Analysis of Bycatch Reduction Devices (BRDs)

A study conducted at Barnegat Bay, New Jersey, by the Marine Academy of Technology and Environmental Science, in conjunction with the Conserve Wildlife Foundation of New Jersey, provides valuable insights into the effectiveness of BRDs.

Goals of the Study

The study had two primary goals:

To determine the effectiveness of BRDs in reducing bycatch.

John Wnek of New Jersey explains that the goal was to compare the amounts and sizes of blue crabs captured in crab pots fitted with various BRDs versus those without BRDs.

Methods

The study involved fitting 12 commercial-style crab pots with malleable chicken-wire funnels and BRDs, while 4 pots without BRDs served as controls. The BRDs used included New Jersey regulation size (2” x 6”), Maryland regulation size (1.75” x 4.75”), and a South Carolina prototype. The pots were set randomly along the shoreline at Barnegat Bay and checked daily over a 15-day period.

Findings

The study found that BRDs significantly reduced bycatch, particularly diamondback terrapins. In crab pots without BRDs, out of 69 terrapins captured as bycatch, 2 were found in pots without BRDs. Over 1,000 crabs were analyzed. The study fished the pots in areas where there was a low chance of capturing terrapins as it wanted to focus on the effect of BRDs on blue crab capture.

Additionally, the study indicated that the use of BRDs did not significantly affect the number or size of blue crabs captured. John Wnek of New Jersey reports that this finding suggests that BRDs are an effective measure for reducing bycatch without compromising the efficiency of crab pots.

Addressing Disparities in Recreational Crabbing Regulations

Despite the regulations in place, there remains a significant disparity in the understanding and compliance among recreational crabbers. Many recreational crabbers are either unaware of the specific regulations or lack the necessary information to comply fully.

Educational Initiatives

To bridge this gap, educational initiatives are crucial. The New Jersey Division of Fish and Wildlife (NJDFW) conducts studies and surveys to monitor crabbing activities and promote responsible practices. However, more efforts are needed to disseminate this information effectively to the recreational crabbing community.

John Wnek explains that one approach is to increase the visibility of regulations through public awareness campaigns, workshops, and informational resources distributed at popular crabbing locations. Local fishing clubs and community groups can also play a vital role in educating members about the importance of compliance with regulations to ensure sustainable crabbing practices.

Importance of Compliance

Compliance with regulations is essential not only for the sustainability of blue crab populations but also for the protection of other marine species and the overall health of the ecosystem. By using BRDs and adhering to size limits and other regulations, crabbers can help maintain the delicate balance of the marine environment.

Conclusion

The responsible use of crab pots in New Jersey is critical to preserving the state’s rich crabbing tradition while protecting the environment. The study conducted at Barnegat Bay highlights the effectiveness of BRDs in reducing bycatch without compromising crab catch rates. However, John Wnek of New Jersey says that addressing the disparity in understanding and compliance with recreational crabbing regulations remains a challenge.

Through increased educational efforts and public awareness campaigns, we can ensure that both recreational and commercial crabbers are well-informed and committed to sustainable practices. By doing so, we can continue to enjoy the bounty of New Jersey’s blue crabs while safeguarding the diverse marine life that inhabits our waters.
