“…natural ecosystems inhabited by crayfish, where only chemical stimuli and no visual recognition are often present. In these habitats, crayfish can also detect movements and vibrations through mechanoreceptors located on antennae and other appendages 70 . However, the extent to which this sensory capacity influences their ability to detect and discern prey or predators remains uncertain.…”

In this study, we experimentally evaluated how the feeding behaviour of marbled crayfish Procambarus virginalis is influenced by cues from conspecifics and the round goby Neogobius melanostomus, a fish predator, in tanks that permitted chemical communication but not visual recognition. We used four experimental groups with different combinations in two sub-tanks. The first sub-tank always contained a crayfish and prey (40 individuals of the water louse Asellus aquaticus). The other sub-tanks were set up as follows: (i) empty, serving as a control (C); (ii) with a conspecific crayfish (Cr); (iii) with a round goby (G) to simulate predator-only odour; and (iv) a round goby and three small conspecific crayfish (G + Cr) to simulate the presence of a predator and/or the alarm odour. Two sub-treatments were defined for the fourth group, categorised as ‘injured’ or ‘not injured’ depending on whether prey crayfish were visibly injured or not, respectively. We observed a significant decline in the consumption of water lice in the G and G + Cr treatments compared to the C and Cr treatments (up to 47% on average). There were no significant differences in consumption between the G and G + Cr treatments, or C and Cr treatments. No significant differences in food consumption parameters were detected between sub-treatments with ‘injured’ and ‘not injured’ conspecific crayfish. Knowledge of modifications in the feeding behaviour of marbled crayfish in the presence of round goby (and fish predators in general) is essential for ecologists attempting to understand the changes and impacts occurring in invaded freshwater ecosystems.

“…Conversely, at the largest scales, Arctic terns and salmon employ the distribution of spatial and temporal cues to perform extensive orientation, facilitating their ability to locate food sources or return to their natal streams (Nevitt et al, 2008 ; Ueda, 2014 ). However, sensory stimuli reflecting abiotic and biotic characteristics can be unevenly distributed in the environment (Clark & Moore, 2018 ; Lunt & Smee, 2015 ). Animals are exposed to multisensory stimuli of varied intensity and duration throughout life (Wagner & Moore, 2022 ), affecting physiology (Iqbal et al, 2023 ), behaviour, morphology and life history (Lima & Dill, 1990 ; Wei & Zhang, 2022 ).…”

Multisensory stimuli provide organisms with information to assess the threat present in the surroundings. Olfactory cues show dominance over other sensory modalities in the aquatic environment. The impact of chemical predator cues combined with experiences gained (learning) in species without previous contact is not fully understood. We investigated the foraging and shelter‐seeking behaviour of naïve and experienced marbled crayfish Procambarus virginalis juveniles in response to the chemical signals of pumpkinseed Lepomis gibbosus alone and in combination with alarm chemicals produced by preyed‐upon conspecifics. Naïve and experienced (previously exposed to pumpkinseed predation) juveniles were stocked in an arena with shelter and feed and exposed (1) to water from a tank containing a predator actively feeding on conspecifics, (2) water from a tank with predator only and (3) water only as control. Crayfish exposed to the combined stimuli avoided the inlet zone and gravitated to shelter zone of the arena to a greater extent than did those exposed to predator‐only cues and the control. Regardless of the treatment, experienced crayfish showed significantly reduced interest in feeding. Our findings imply that crayfish response to threat‐associated odours with the greatest potency when visual or tactile cues are present, while previous encounters with predators may make them more cautious.

“…A sensory landscape describes the spatial and temporal distribution of stimuli in a given environment, which can be affected by both biotic and abiotic factors (Wilson and Weissburg 2013;Lunt and Smee 2015;Clark and Moore 2018). The sensory landscape is composed of information contained in the intensity, spatial and temporal distribution, and elemental composition of the cues themselves, such as the combination of aromas, colors, and different sounds of sensory stimuli (Fine et al 2010).…”

Are you scared yet? Variations to cue indices elicit differential prey behavioral responses even when gape-limited predators are relatively small

Anti-predator behavior is often evoked based on measurements of risk calculated from sensory cues emanating from predators independent of physical attack. Yet, the exact sensory indices of cues utilized in risk assessment remain largely unknown. To examine how different predatory cue indices of information are used in risk assessment, we presented prey with various cues from sub-lethal gape-limited predators. Rusty crayfish (<i>Faxonius rusticus</i> (Girard, 1852)) were exposed to predatory odors from sub-lethal sized largemouth bass (<i>Micropterus salmoides</i> (Lacepѐde, 1802)) to test effects of changing predator abundance, relative size relationships, and total predator length in flow through mesocosms. Foraging, shelter use, and movement behavior were used to measure cue effects. Foraging time depended jointly upon predator abundance and total predator size (p = 0.030). Specifically, high predator abundance resulted in decreased foraging efforts as gape ratio increased. Similarly, sheltering time depended on the interaction between predator abundance and gape ratio when predator abundance was highest (p = 0.020). Crayfish significantly increased exploration time when gape ratio increased (p = 0.010). Thus, this study shows crayfish can utilize different indices of predatory cues, namely total predator abundance and relative size ratios, in risk assessment but do so in context specific ways.
