Artificial Light in Commercial Industrialized Fishing Applications: A Review

Abstract

Fishing with an artificial light stimulus has existed for thousands of years. It started with simple techniques such as burning a large fire on the beach to attract fish, but over the centuries it has become increasingly technologically advanced. Today, the use of artificial light in commercial fishing plays a very important role in contributing to the total catch yield and economy of many industrialized fisheries. In most cases, fishing vessels employ lights at the surface, but more recently, low-powered LED lights installed directly on fishing gear have also become common. Using artificial light in commercial fishing applications appears to produce various outcomes and trade-offs (i.e., positive and negative effects). Positive benefits can include increases in catch rate, reductions in bycatch, and savings in energy, while negative effects can include ecological costs, overfishing, increased bycatch, production of plastic and marine litter, and greenhouse gas emission. This review provides an overview of fish vision in aquatic animals and the use of light in commercial industrialized fisheries, and provides discussion on potential solutions that strengthen the positive effects and minimize the negative effects of using artificial light in fishing applications.

Application of Luminescent Netting in Traps to Improve the Catchability of the Snow Crab Chionoecetes opilio

“…Light intensity and wavelength are known to affect animal behavior (see review by Nguyen and Winger ). We suggest that further research should be conducted to determine the potential benefits of increasing the percentage of luminescent fibers that are woven into the EuroGlow product used in this study.…”

Shining a light on mitigation measures to reduce undesirable mortality in fish

“…Recording the responses of multiple species to the use of different configurations of light is a useful means to rapidly assess which species may or may not respond in different ways. What this reveals is the variability in response of different species to light: the same wavelength may deter some species, while attracting or have no impact on other species (Nguyen & Winger, 2019;Elvidge et al 2019). Given the developments that have occurred in LED technology, the ability to introduce light into the aquatic environment in different formats (e.g., spotlights, light sticks, illuminated braids, illuminated fibres in ropes), this promises to be a rich area for research in the future.…”

RESPONS RAJUNGAN (Portunus pelagicus) TERHADAP WARNA CAHAYA YANG BERBEDA PADA UJI LABORATORIUM

“…Knight & Leggett (1985) dalam hasil penelitiannya mengungkapkan bahwa kepiting jenis Paragrapsus gaimardii sensitif salah satunya pada warna ultraviolet. Warna dan intensitas memainkan peran penting dalam menghasilkan stimulus (Nguyen & Winger, 2018).…”

“…Rajungan merupakan filum arthropoda dari kelas krustasea dan sub kelas malacostraca (Stephenson & Campbell, 1959). Krustasea yang juga merupakan hewan akuatik turut memanfaatkan cahaya sebagai stimulus seperti hewan pelagis lainnya (Nguyen &Winger, 2018). Kemampuan krustasea dalam menerima cahaya berbeda-beda baik secara kelas maupun spesies, hal trsebut berkaitan dengan fungsi reseptor yang dimiliki pada masing-masing krustasea (Glantz & Barnes, 2002).…”
