Population and Management of Silver Hake

Silver hake, also known as whiting, is a commercially targeted species in the US. It is managed in two stocks, northern and southern, both of which are currently not overfished nor undergoing overfishing.

However, the silver hake fishery must consider its co-occurrence with many regulated groundfish species. Management strategies need to address the impact the silver hake fishery may have on these species to ensure sustainable fishing practices.

Exempted gears, which are allowed to target silver hake, must demonstrate limited catches of regulated groundfish species. This ensures that the fishery remains within the required thresholds and contributes to the overall management and conservation of US Silver Hake stocks.

Gear Exemptions for Silver Hake Fishing

When it comes to sustainable Silver Hake fishing in the US, specific gear exemptions play a crucial role. Due to the small girth of adult Silver Hake, they are managed under exemptions to the northeast multispecies management plan. These exemptions allow for the use of mesh sizes smaller than the minimum mesh for groundfish, facilitating targeted fishing efforts.

To ensure sustainable Silver Hake fishing practices, these gear exemptions permit the use of small-mesh trawls in designated areas, at specified time periods, with specific gears, bycatch reduction devices, or a combination of them. By implementing these exemptions, there has been an increase in Silver Hake catches in certain areas, contributing to the overall sustainability of the fishery.

By utilizing the approved gear and following the regulations, fishermen can effectively target Silver Hake while minimizing the impact on non-target species and ensuring a sustainable fishing industry.

Alternative Gear Designs for Silver Hake Fishing

Raised footrope trawls (RFT) and drop-chain-only trawls (DOT) are innovative gear designs that have been tested for silver hake fishing. These alternative gears show promise in reducing bycatch of regulated groundfish species while maintaining commercial levels of silver hake catch. By targeting silver hake more selectively, these gear designs contribute to conservation efforts and sustainable fishing practices.

One promising alternative design is the raised footrope trawl (RFT). This gear elevates the footrope higher off the seafloor, minimizing contact with bottom-dwelling species and reducing bycatch. The raised footrope trawl is designed to specifically target silver hake while minimizing the capture of non-target species.

The drop-chain-only trawl (DOT) is another alternative gear design that has shown potential in reducing bycatch. This design uses a trawl net with vertical chains dropped from the headline, creating gaps in the net. These gaps allow smaller fish to escape while retaining the target species, such as silver hake. By reducing the capture of non-target species, the drop-chain-only trawl contributes to sustainable fishing practices.

Additionally, the large-mesh belly window trawl (LMBW) has been successful in reducing bycatch of flatfish in other fisheries and may offer a viable alternative for silver hake fishing. This gear design incorporates large-mesh panels in the belly of the trawl, allowing certain species to escape through the larger mesh. The large-mesh belly window trawl improves selectivity by selectively capturing the target species, such as silver hake, while reducing the capture of non-target species.

Conservation engineering plays a crucial role in developing and refining these alternative gear designs. By prioritizing sustainability and minimizing the impact on non-target species, these innovative gears contribute to the long-term viability of the silver hake fishery and support ecosystem conservation.

“The use of alternative gear designs, such as raised footrope trawls, drop-chain-only trawls, and large-mesh belly window trawls, shows promise in reducing bycatch while maintaining commercial levels of silver hake catch.”

Incorporating these alternative gear designs not only benefits the silver hake fishery but also helps to preserve the delicate balance of marine ecosystems. By striving for sustainable fishing practices and using innovative gears, fishermen can protect not only silver hake populations but also the diverse range of species present in the ocean.

Challenges in the Maine Silver Hake Fishery

The Maine Silver Hake fishery faces unique challenges due to the rugged bathymetry and rocky, irregular topography of Maine’s coastal waters. These distinctive characteristics make fishing with raised footrope trawls and drop-chain-only trawls impractical in this region. The traditional rockhopper footropes have been essential for effective fishing in Maine, as they minimize the tearing of belly netting while navigating the rough grounds.

Fishing challenges in Maine waters arise from the complex bathymetry and rocky seabed, which require specialized gear and techniques to overcome. The gear limitations in Maine waters restrict the use of certain trawling methods, impacting the silver hake fishery’s productivity and sustainability. As a result, the implementation of gear exemptions that have proven successful in Massachusetts waters may not yield the same results in Maine.

Rocky seabed and rugged bathymetry

Maine’s coastal seabed comprises rocky areas and irregular topography, creating difficulties for fishing vessels using raised footrope trawls and drop-chain-only trawls. These gear types are designed for smooth seabeds and are more prone to damage in the rocky terrain of Maine’s waters.

“The rugged nature of Maine’s coastal seabed presents significant challenges for fishermen utilizing raised footrope trawls and drop-chain-only trawls. These gear types are not well-suited to the rocky, irregular topography of the region.”

Specialized gear limitations

Maine’s unique fishing environment necessitates the use of specialized gear, specifically rockhopper footropes, to navigate the rough grounds effectively. These footropes provide enhanced durability and minimize netting damage, allowing fishermen to maintain productive silver hake catches despite the challenging conditions.

• Raised footrope trawls and drop-chain-only trawls are impractical due to frequent tearing of the belly netting when fishing over rough grounds.
• Maine fishermen rely on rockhopper footropes to sustain their fishing operations and optimize their catch in the face of gear limitations.

The gear limitations in Maine water necessitate innovative approaches and adaptations to overcome the challenges posed by the rugged bathymetry and rocky seabed. By considering the unique fishing conditions and exploring alternative gear designs, the Maine Silver Hake fishery can continue to thrive amidst these challenges.

The Role of Large-Mesh Panels in Silver Hake Fishing

The silver hake fishery faces the challenge of reducing bycatch of regulated groundfish species while maintaining commercial catch rates. One promising solution is the use of large-mesh panels inserted into the belly of trawls. These panels have shown to be effective in several ways.

1. Bycatch Reduction: The large-mesh panels take advantage of the behavior of flatfish, which associate with the bottom and tend to stay low upon entering the trawl mouth. This behavior increases the likelihood of capturing flatfish in the panel, reducing their capture in the main trawl and minimizing bycatch of regulated groundfish species.
2. Selectivity Improvement: The use of large-mesh panels improves the selectivity of the trawl, allowing silver hake to be retained while reducing the capture of non-target species. This targeted approach enhances the sustainability of the fishery by minimizing the impact on other marine species.
3. Escape of Juvenile Species: Another benefit of large-mesh panels is their potential to increase the escape of juvenile regulated groundfish species and juvenile silver hake. By providing an escape route for these young fish, the panels contribute to the overall health and resilience of the fish populations.

“The use of large-mesh panels in the silver hake fishery represents a significant step towards sustainable fishing practices. These panels not only reduce bycatch of regulated groundfish species but also improve selectivity and promote the escape of juvenile fish. By incorporating such innovative gear designs into fishing operations, we aim to protect our marine ecosystems while maintaining viable fishing opportunities.” – [Your Name], Marine Biologist
