“…The biogenic amines serotonin (5-HT, 5-hydroxytryptamine) and octopamine (OA, DL-octopamine) are recognized to play an important role in controlling the aggression of crustacean decapods Kravitz 1988Kravitz , 2000Fingerman et al 1994;Huber et al 1997a, b;Weiger 1997). Both were found to exert their effects by acting in three basic modes: as classical neurotransmitters, as neuromodulators or as neurohormones (Orchard 1982;Weiger 1997).…”

This study aimed at understanding the influence of biogenic amines on the agonistic behaviour of the crayfish Procambarus clarkii, a model organism for crustacean decapods. Specifically, we investigated whether the hierarchical rank of fighting individuals might be altered by injecting solutions of either serotonin or octopamine into their haemolymph. First, we assessed the effect and duration of the bioamines on the behaviour, posture, and chelar force of 60 adult males paired for size. Then, we examined their potential to modify dominance hierarchies by observing, for 2 h after the treatment, the behaviour of three categories of familiar size-matched pairs: (1) 20 'control pairs' (both individuals injected with a physiological solution), (2) 20 'reinforced pairs' (the dominant individual, alpha, injected with serotonin, and the subordinate individual, beta, with octopamine), and (3) 20 'inverted pairs' (alpha injected with octopamine and beta with serotonin). The results clearly show that the two bioamines were able to alter the posture and aggressiveness of the treated individuals in opposite directions without affecting their chelar force. However, the large majority of the 'inverted pairs' retained their former position in the hierarchy. The role that intrinsic characteristics and prior social experience play in maintaining dominance hierarchies in crayfish is discussed.

“…Like serotonin, dopamine acts as both a neurohormone and a transmitter in lobsters: It is released from central sites as well as into the hemolymph (Cooke and Sullivan, 1982;Kravitz, 1988;Fingerman et al, 1994). In the mature lobster nervous system, dopamine acts directly on muscle period of larval life is brief relative to the embryonic period.…”

Dopamine-immunoreactive neurons were revealed in lobster embryos, larvae, and postlarvae, and staining patterns were compared to neuronal labeling in the juvenile lobster nervous system (Cournil et al. [1994] J. Comp. Neurol. 344:455-469). Dopamine immunoreactivity is first detected by midembryonic life in 35-40 neuronal somata located anteriorly in brain and subesophageal ganglion. When the lobsters assume a benthic life during the first postlarval stage, an average of 58 cell bodies are labeled. The acquisition of dopamine in lobster neurons is a protracted event spanning embryonic, larval, and postlarval life and finally reaching the full complement of roughly 100 neurons in juvenile stages. Some of the dopaminergic neurons previously identified in the mature nervous system, such as the paired Br cells, L cells, and mandibular cells, are labeled in embryos and persist throughout development. In contrast, other neurons stain transiently for dopamine during the developmental period, but, by the adult stage, these neurons are no longer immunoreactive. Such transiently labeled neurons project to the foregut, the thoracic dorsal muscles, the neurohormonal pericardial plexus, and the pericardial pouches. It is proposed that these neurons are alive and functioning in adult lobster but that dopamine levels have been abolished, providing that neurotransmitter status is a dynamic, changing process.

“…This treatment resulted in a dramatic reduction of the neuropil size of the accessory lobes as compared to control brains. In any case, it should be recognized that already in the larvae serotonin probably exerts some of the wealth of actions which are attributed to its function as a neurotransmitter in adult crustaceans (Fingerman et al, 1994). Thus, patterns of immunostaining seen in the larvae are likely to represent some kind of combination of neurotrophic and neurotransmitter-like functions.…”

“…More recent studies have pointed out the ability of serotonin to modulate a wide range of physiological and behavioural processes in adult crustaceans (for reviews see Harris-Warrick et al, 1989 andFingerman et al, 1994). Thus, serotonin influences the postural behaviour in lobsters (Livingstone et al, 1980;Harris-Warrick and Kravitz, 1984) and mediates inhibition of the lateral giant Corresponding author: Dr Ralph R. Dawirs escape response in crayfish (Glanzman and Krasne, 1986).…”

Larval development in crabs is characterized by a striking double metamorphosis in the course of which the animals change from a pelagic to a benthic life style. The larval central nervous system has to provide an adequate behavioural repertoire during this transition. Thus, processes of neuronal reorganization and refinement of the early larval nervous system could be expected to occur in the metamorphosing animal. In order to follow identified sets of neurons throughout metamorphosis, whole mount preparations of the brain and ventral nerve cord of laboratory reared spider crab larvae (Hyas araneus) were labelled with an antibody against the neurotransmitter serotonin. The system of serotonin-immunoreactive cell bodies, fibres and neuropils is well-developed in newly hatched larvae. Most immunoreactive structures are located in the protocerebrum, with fewer in the suboesophaegeal ganglia, while the thoracic and abdominal ganglia initially comprise only a small number of serotonergic neurons and fibres. However, there are significant alterations in the staining pattern through larval development, some of which are correlated to metamorphic events. Accordingly, new serotonin-immunoreactive cells are added to the early larval set and the system of immunoreactive fibres is refined. These results are compared to the serotonergic innervation in other decapod crustaceans.
