“…The concentrations were selected based on laboratory experiments conducted in Di Rocco et al (2016). The pumps (model: MasterFlex L/S 7533-20, Vernon Hills, IL, USA) were calibrated to 105 mL min À1 , regardless of the discharge of the river during that trial.…”

“…A combination of the sea lamprey extract and PEA HCl treatments, dosed simultaneously, was also tested to verify previous laboratory findings suggesting that these cues interact additively (Di Rocco et al 2016). Extract was made using the same procedure as the previous experiment and delivered at the same concentration as the previous experiment (2.3 mg L À1 ).…”

“…A new batch of PEA HCl (Hard Rhino, Phoenix, AZ, USA, purity >95%) was used and was applied at a concentration of 1 9 10 À7 M. This concentration was lower than that used in experiments 1 and 2 (5 9 10 À7 M, 5 9 10 À6 M, respectively), but was within the range of concentrations shown to elicit a response in laboratory flumes (response observed at concentrations as low as 3 9 10 À9 M; Di Rocco et al 2016). Sea lamprey extract was made using the same procedure and applied at the same concentration as in experiments 1 and 2 (2.3 mg L À1 ), except that prior to being pumped, the extract was strained again with cotton cheese cloth to minimise clogging in the pump tubing.…”

“…Considering the above, and that fishes have been shown to avoid waste products of predators (e.g. Sea lamprey avoided commercial PEA (PEA HCl) at concentrations as low as 3 9 10 À9 M Di Rocco et al 2016). Sea lamprey avoided commercial PEA (PEA HCl) at concentrations as low as 3 9 10 À9 M Di Rocco et al 2016).…”

“…The putative predator cue, 2-phenylethylamine (PEA), has received considerable recent attention in studies with sea lamprey (Di Rocco et al , 2016Imre et al 2014). PEA is found in the urine of mammalian predators and is recognised as a predator cue by some rodents (Ferrero et al 2011).…”

Three in‐stream experiments were conducted to determine whether sea lamprey, Petromyzon marinus L., tissue extract (alarm cue) and 2‐phenylethylamine hydrochloride (PEA HCl, a putative predator cue) influenced the distribution of migrating adult sea lamprey. Experiments evaluated sea lamprey movement when an odour was applied to (1) a tributary of a larger stream; and (2) half of a stream channel. Fewer sea lamprey entered the tributary and side of the river scented with sea lamprey tissue extract compared to the control treatment. Sea lamprey did not avoid the tributary and side of the river scented with PEA HCl. A final laboratory experiment found no difference in the avoidance response of sea lamprey to PEA HCl mixed with river water vs PEA HCl mixed with water from Lake Huron. As such, the lack of sea lamprey response to PEA HCl in the stream was unlikely to have been caused by the presence of the river water. Rather, the difference between laboratory and field results may be attributed to the complexity of the physical environment.

Ocean Acidification Amplifies the Olfactory Response to 2-Phenylethylamine: Altered Cue Reception as a Mechanistic Pathway?

et al. 2021

With carbon dioxide (CO2) levels rising dramatically, climate change threatens marine environments. Due to increasing CO2 concentrations in the ocean, pH levels are expected to drop by 0.4 units by the end of the century. There is an urgent need to understand the impact of ocean acidification on chemical-ecological processes. To date, the extent and mechanisms by which the decreasing ocean pH influences chemical communication are unclear. Combining behaviour assays with computational chemistry, we explore the function of the predator related cue 2-phenylethylamine (PEA) for hermit crabs (Pagurus bernhardus) in current and end-of-the-century oceanic pH. Living in intertidal environments, hermit crabs face large pH fluctuations in their current habitat in addition to climate-change related ocean acidification. We demonstrate that the dietary predator cue PEA for mammals and sea lampreys is an attractant for hermit crabs, with the potency of the cue increasing with decreasing pH levels. In order to explain this increased potency, we assess changes to PEA’s conformational and charge-related properties as one potential mechanistic pathway. Using quantum chemical calculations validated by NMR spectroscopy, we characterise the different protonation states of PEA in water. We show how protonation of PEA could affect receptor-ligand binding, using a possible model receptor for PEA (human TAAR1). Investigating potential mechanisms of pH-dependent effects on olfactory perception of PEA and the respective behavioural response, our study advances the understanding of how ocean acidification interferes with the sense of smell and thereby might impact essential ecological interactions in marine ecosystems.

Chemical cues for intraspecific chemical communication and interspecific interactions in aquatic environments: applications for fisheries and aquaculture

2021

Aquatic organisms detect chemical cues to sense the local environment, for example, to find a mate, locate food, and identify danger. Knowledge of chemical cues can be used in aquaculture, in practical applications such as controlling mating behavior to increase fertility, enhance feeding, and decrease stress; in fisheries, by catching selected species with low-cost artificial attractants; and to address maritime issues, by decreasing biofouling. Aquatic organisms also detect chemical cues related to global environmental changes, ocean acidification, and increases in ocean plastics, all of which can affect their chemosensory behaviors. Here we discuss the nature of chemical cues and chemosensory biology and ecology of aquatic organisms, and potential applications with an emphasis on sex pheromones in commercially important and well-studied animals, namely, decapod crustaceans and fish.
