“…Intense crossing activity had also been described in laboratory-caged sea bass [26], where crossing in series of several individuals were observed through the net tear. The continuous crossing activity during the study is likely to either search for food or tank exploitation, while comes in agreement with similar results in fisheries study with other species [4] where mackerels, tuna as well as other species tended to move in and out of the illuminated field driven by feeding motivation. Significantly higher number of crossings after the feeding time in all fish groups might suggest that fish swimming and feed intake is unaltered from the illumination level.…”

“…Nevertheless, future research should be focused on different light intensities or light regimes and the potential behavioural effect on caged sea bass. For example, studies in fisheries have already shown species attraction by shorter wavelength lights [4]. In parallel with fisheries, related studies have already shown promising results for salmon manipulation [17] and pathogen avoidance [5] through guidance in different swimming depths.…”

“…Particularly, biorhythms have been related to feeding time, either in nature or aquaculture as well as under restricted feeding conditions [3]. In recent years, artificial light has been introduced in both fisheries [4] and aquaculture [5] towards attraction to specific areas and population guide for manipulation and avoidance of unfavorable conditions [6,7].…”

“…Up to now, such studies have been mostly involved feeding behaviour towards on-demand technology [9,10] growth and survival of larvae [11]. In parallel, fisheries studies have not clarify species preference to certain light intensities [4]. Sea bass tended to continuously swim around a light source, but neither attracted nor inhibited by the light source.…”

“…Such studies are essential, since they promote welfare conditions for early domesticated species in aquaculture. However, they could further suggest light as another option to manipulate Mediterranean species in any field of the aquaculture production, a widely used technology in Atlantic salmon culture [4,5,21].…”

The study investigated the behavior of European sea bass (Dicentrarchus labrax), in laboratory-scale conditions and controlled light environment. Fish were confined in tanks that had been previously split into two equal compartments. A tear on the net allowed fish to freely moved between the two compartments. An extra net frame, placed above tanks altered light environment to: (1) Illuminated Holding Area -Shadow Escape Area, (2) Shadowed Holding Area -Illuminated Escape Area and 3) Illuminated Holding Area -Illuminated Escape Area, as control condition, for a period of 13 days. Sea bass showed a strong preference to the illuminated compartment of the tank, from the beginning of the trials. Crossings to the shadowed compartment were regular but always followed by a reverse action to the illuminated area. In addition, they occurred in series of 7 individuals. Reverse crossings to the initial shadowed compartment were rarely observed throughout the experiment, even if fish had to suffer starvation. Behavioural results regarding sea bass light preference may have essential implications in marine biology and aquaculture, including species domestication as well as manipulation via artificial light.

Conservation behaviour is an area of conservation biology particularly suited to investigate problems of species endangerment associated with managing animals in fragmented habitats and isolated parks. It employs a theoretical framework that examines the mechanisms, development, function and phylogeny of behavioural variation in order to develop practical tools for preventing extinction. This framework can be used to attract animals to suitable habitat, restore migratory movements, identify individual reproductive strategies affecting conservation and focus protection on species most susceptible to extinction. The future success of conservation behaviour requires that behaviourists link individual variation in behaviour to processes that determine population viability. Key concepts Animal conservation will require active management. Behavioural problems must be examined from four perspectives (mechanisms, ontogeny, adaptive function, phylogeny) simultaneously. Behavioural strategies of individual animals change as habitat and populations are altered, and those changes could harm population viability. Animal behaviourists must participate in conservation planning to protect the future of biodiversity.

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

et al. 2019

In this study, we investigated luminescent netting as a means to improve the catch rates of snow crabs Chionoecetes opilio. A laboratory experiment was conducted to investigate the intensity and duration of luminescence using time‐lapse photography. We exposed experimental traps to five different treatments of UV light to excite the luminescent fibers in the netting. Our results showed that luminescent netting can be effectively activated to emit light, and that the resulting intensity and duration of luminescence emitted over time depends on the initial duration of UV exposure and the source of light. A fishing experiment was subsequently conducted in eastern Canada to compare the catch rate of traditional and luminescent traps, and to determine how soak time affected catch rate. Results indicate that the effect of luminescent traps on the CPUE (measured as number of crab per trap) depended on the soak time. The CPUE was significantly higher (a 55% increase) in luminescent traps that underwent relatively short soak times (~1 d), but when soak times were longer (~8 d), the CPUE was not significantly different.
