Introduction

In the ever-evolving world of fishing, technological advancements have played a crucial role in enhancing efficiency and sustainability. One such innovation that has revolutionized modern fishing practices is dropline technology. Droplines, also known as bottom longlines, are fishing gears consisting of a mainline with numerous baited hooks attached at regular intervals. This article explores the vital role of dropline technology in modern fishing practices, highlighting its benefits, applications, and contributions to sustainable fishing [1].

Enhanced targeting and catch efficiency

Droplines offer fishermen a highly targeted approach to capture specific species, increasing catch efficiency while reducing bycatch. By precisely positioning baited hooks at predetermined depths, fishermen can target demersal or bottom-dwelling fish species with greater accuracy. This targeted fishing method minimizes the capture of nontargeted species, thus reducing environmental impact and promoting sustainable fishing practices [2].

Increased selectivity and reduced bycatch

One of the significant advantages of dropline technology is its ability to reduce bycatch, the unintended capture of non-targeted species. With carefully placed hooks and effective baiting strategies, fishermen can significantly minimize the capture of undersized or protected species. By reducing bycatch, droplines contribute to the preservation of marine biodiversity and help maintain the overall health of ecosystems [3].

Improved gear efficiency and durability

Droplines are designed to be highly efficient and durable, allowing fishermen to maximize their catch potential while minimizing gear loss. Modern droplines are often made from robust materials, such as synthetic fibers or stainless steel, ensuring longevity and resistance to wear and tear. Additionally, advancements in hook designs and materials have led to improved hook retention, reducing the chances of fish escaping once hooked (Table 1) [4].
