Understanding Bycatch

Definition of bycatch

Bycatch refers to the unintentional capture and subsequent discard of non-target species during fishing operations. It occurs when fishing gear is deployed with the intention of catching a specific species, but other species are inadvertently caught and often discarded. Bycatch is a significant issue in various fisheries around the world and can have detrimental ecological, economic, and social impacts.

Importance of reducing bycatch

Reducing bycatch is crucial for the sustainability and long-term viability of fisheries. Bycatch can lead to the overexploitation of non-target species, causing declines in their populations and disrupting the balance of marine ecosystems. It also has economic implications, as discarded bycatch represents a waste of resources and can lead to financial losses for fishermen. Additionally, bycatch can negatively impact local communities dependent on fisheries, as it can reduce the availability of target species and disrupt traditional fishing practices.

Common species affected by bycatch

Numerous species are affected by bycatch, including but not limited to marine mammals, seabirds, sharks, sea turtles, and non-target fish species. For example, dolphins and porpoises often become entangled in fishing nets intended for tuna and other pelagic species. Sea turtles can get caught in longlines, and seabirds can become hooked on baited fishing hooks. Bycatch threatens the survival of these species and compromises the overall health and biodiversity of marine ecosystems.

Causes of Bycatch

Fishing gear and methods

Certain types of fishing gear and methods are more prone to bycatch than others. For example, bottom trawling, a method used to catch demersal fish species by dragging a net along the ocean floor, often results in high levels of bycatch. Similarly, gillnets, which are used for both commercial and recreational fishing, can entangle and lead to the unintended capture of non-target species. The design and usage of fishing gear play a significant role in determining the amount of bycatch occurring in fisheries.

Unintentional capture of non-target species

Often, fishermen do not actively target non-target species, but they are inadvertently caught due to their presence in the same area as the target species. This unintentional capture can occur when fishing gears are not species-specific and cannot discriminate between the targeted species and other marine organisms. Factors such as the behavior, size, and habitat overlap between target and non-target species contribute to the likelihood of bycatch.

Lack of regulatory measures

In some regions, there is a lack of effective regulations and enforcement measures to address bycatch. The absence of specific bycatch mitigation requirements allows fishing activities to go unchecked, exacerbating the problem. Without adequate regulations and incentives to reduce bycatch, the negative impacts on marine life and ecosystems will persist. It is essential to prioritize the implementation of robust regulatory measures to minimize bycatch.

Bycatch reduction devices

Bycatch reduction devices (BRDs) are specialized devices or modifications to fishing gear aimed at reducing the capture of non-target species. BRDs can be used in various types of fishing gear, such as trawls, longlines, and gillnets. Common examples include turtle excluder devices (TEDs) and modifications to fishing hooks. These devices allow non-target species to escape from fishing gear, significantly reducing bycatch mortality.

Acoustic deterrent devices

Acoustic deterrent devices (ADDs) are devices that emit sound or underwater vibrations to deter non-target species from entering fishing areas. These devices can be used to minimize the interaction between fishing gear and marine mammals, seabirds, and sea turtles. By emitting non-harmful noises or vibrations, ADDs create a deterrent effect, reducing the likelihood of bycatch.
