“…Our findings on Procambarus fallax support data from previous studies that crayfish can effectively discriminate and localize odors with high precision (see Breithaupt 2011). We take this as evidence that in principle the design of our bioassay and the experimental parameters are suitable to study odor tracking in malacostracan crustaceans.…”

“…In aquatic organisms, chemical stimuli provide highly important cues for survival and reproduction because they indicate the availability of resources such as food, shelters or substrates for larval settlement, and allow assessing the presence of predators, conspecifics and potential mates (Derby and Sorensen 2008;Thiel 2011;Wyatt 2011;Breithaupt 2011;Weissburg 2011). Aquatic crustaceans live in a world full of chemicals.…”

“…In order to document the efficiency of our setup, we used the same bioassay to examine olfactoryguided behavior in the marbled crayfish Procambarus fallax forma virginalis (Decapoda). It is well documented that crayfish use chemical senses to detect the presence of predators, assess social hierarchies and find shelters and food (see Breithaupt 2011). They also display a highly effective odor-tracking behavior in Y-mazes (Schneider et al 1999).…”

Heading which way? Y-maze chemical assays: not all crustaceans are alike

In a world full of chemicals, many crustaceans rely on elaborate olfactory systems to guide behaviors related to finding food or to assess the presence of conspecifics and predators. We analyzed the responses of the isopod Saduria entomon to a range of stimuli by which the animal is likely to encounter in its natural habitat using a Y-maze bioassay. In order to document the efficiency of the experimental design, the same bioassay was used to test the behavior of the crayfish Procambarus fallax whose ability to track odors is well documented. The crayfish performed well in the Y-maze and were able to locate the source of a food-related odor with high fidelity. The isopod S. entomon reacted indifferently or with aversion to most of the stimuli applied. In 1800 trials, only four out of 15 different stimuli yielded statistically significant results, and only one odorant was found to be significantly attractive.The findings raise several questions whether the stimuli presented and/or the experimental setup used represents an ecologically relevant situation for S. entomon. In each instance, our experiments illustrate that established methods cannot be readily transferred from one species to another.

“…Similar to other decapods (e.g. clawed lobsters, spiny lobsters, and crayfish; Aggio and Derby 2011;Breithaupt 2011), the first and second antennae are the main sites to perceive olfactory and contact signals ( Fig. 5.1).…”

Social Recognition in Invertebrates

Common in most aquatic environments, shrimps occur in a wide range of social associations with conspecific and other species, and express various levels of social recognition. We review the mechanisms and forms of social recognition in shrimps, emphasizing the Caridea. Most research has been conducted on Alpheidae, Hymenoceridae, Hippolytidae, Palaemonidae and Stenopodidae. The olfactory first and chemotactile second antennae are important in perceiving waterborne cues/ pheromones and contact pheromones. Potential distance and contact pheromones have been strongly suggested by behavioural studies in several species and even tentatively identified in a few species. All forms of social recognition and interspecific communication have been documented in shrimps, including recognition by mate, size, rank, kin and individual. Given the diversity of ecology, mating and social behaviour, and the previous research on social recognition in caridean shrimps, this group is a promising productive model taxon for studies in animal communication.

“…Adult males are also more active than females in initiating reproductive interactions. They can recognise female sex pheromones contained in urine pulses that females release during initial aggressive bouts that precede mating (Breithaupt, 2010). While chemical signals often play an important role in agonistic interactions in many decapod crustaceans, it is not clear which parts of the chemosensory system are important for processing the signals (Schmidt & Mellon, 2010).…”
