Crustaceans are often exposed to hypoxic stress in intensive aquaculture systems. Such stress leads to physiological, behavioural and biochemical changes, which can cause various metabolic disorders or even death. Crustacean response mechanisms to hypoxia stress are known to be complex, with their regulation involving multiple genes. In this review, after briefly exploring some known causes of hypoxic stress in aquaculture systems, we discuss the physiological adaptation strategies used by crustaceans in response to hypoxia and summarise recent information regarding the effects of hypoxia on the behaviour, survival, antioxidant ability, metabolic processes and innate immunity of crustaceans. In addition, we give particular emphasis to the known molecular mechanisms underlying hypoxia related to the hypoxia‐inducible factor 1 (HIF‐1) signalling pathway, the adenosine 5′‐monophosphate‐activated protein kinase signalling (AMPK) pathway, and apoptosis. Practically, it is clear that multiple measures need to be taken to prevent and regulate the adverse effects of hypoxic stress in intensive aquaculture systems, including development of hypoxia‐resistant breeds and nutritional regulation techniques. Overall, this review provides a theoretical basis for understanding the molecular mechanisms underlying hypoxic stress in crustaceans, while making conceptual connections with data from related study areas in other species.

“…Besides sensitivity to chemical and mechanical cues, crustaceans detect other stimuli, including temperature (Ache, 1982;Lagerspetz and Vainio, 2006), salinity (Dufort et al, 2001), and oxygen (Lima et al, 2021). Although the identity and nature of the sensors for these stimuli are poorly understood (Mellon, 2014), antennules are strong candidates for housing these sensors.…”

“…It is a major chemosensory organ; but beyond sensing chemicals, the antennule is also exquisitely sensitive to mechanical stimuli, including touch and water-borne vibrations, providing information that crustaceans use in many of their activities (Mellon, 2012;Reidenbach, 2018). The antennules also likely have sensors of other environment stimuli, such as temperature, oxygen, pH, salinity, and nociceptive stimuli (Larimer, 1964;Ache, 1982;Derby and Blaustein, 1988;Lagerspetz and Vainio, 2006;Shabani et al, 2007;Puri and Faulkes, 2015;Lima et al, 2021). Furthermore, the antennule is a motor organ: it is actively moved in three dimensions to survey its sensory environment, including its iconic behavior-antennular flicking-which it uses to temporally and spatially sample the animal's chemo-mechanical surroundings (Snow, 1973;Schmitt and Ache, 1979;Reidenbach, 2018).…”

The crustacean first antenna, or antennule, has been an experimental model for studying sensory biology for over 150 years. Investigations have led to a clearer understanding of the functional organization of the antennule as an olfactory organ but also to a realization that the antennule is much more than that. Across the Crustacea, the antennules take on many forms and functions. As an example, the antennule of reptantian decapods has many types of sensilla, each with distinct structure and function and with hundreds of thousands of chemosensory neurons expressing hundreds of genes that code for diverse classes of receptor proteins. Together, these antennular sensilla represent multiple chemosensory pathways, each with its own central connections and functions. The antennule also has a diversity of sensors of mechanical stimuli, including vibrations, touch, water flow, and the animal's own movements. The antennule likely also detects other environmental cues, such as temperature, oxygen, pH, salinity, and noxious stimuli. Furthermore, the antennule is a motor organ-it is flicked to temporally and spatially sample the animal's chemo-mechanical surroundings-and this information is used in resolving the structure of chemical plumes and locating the odor source. The antennule is also adapted to maintain lifelong function in a changing environment. For example, it has specific secretory glands, grooming structures, and behaviors to stay clean and functional. Antennular sensilla and the annuli on which they reside are also added and replaced, leading to a complete turnover of the antennule over several molts. Thus, the antennule is a complex and dynamic sensory-motor integrator that is intricately engaged in most aspects of the lives of crustaceans.

Oxygen is an essential gasotransmitter directly sensed via protein gasoreceptors

The current restrictive criteria for gasotransmitters exclude oxygen (O2) as a gasotransmitter in vertebrates. In this manuscript, I propose a revision of gasotransmitter criteria to include O2 per se as a signaling molecule and 'essential gasotransmitter' for vertebrates. This revision would enable us to search for protein‐based O2‐binding sensors (gasoreceptors) in all cells in the brain or other tissues rather than specialized tissues such as the carotid body or gills. If microorganisms have protein‐based O2‐binding sensors or gasoreceptors such as DosP or FixL or FNR with diverse signaling domains, then eukaryotic cells must also have O2‐binding sensors or gasoreceptors. Just as there are protein‐based receptor(s) for nitric oxide (GUCY1A, GUCY1B, CLOCK, NR1D2) in cells of diverse tissues, it is reasonable to consider that there are protein‐based receptors for O2 in cells of diverse tissues as well. In mammals, O2 must be acting as a gasotransmitter or gaseous signaling molecule via protein‐based gasoreceptors such as androglobin that very likely mediate acute sensing of O2. Accepting O2 as an essential gasotransmitter will enable us to search for gasoreceptors not only for O2 but also for other nonessential gasotransmitters such as hydrogen sulfide, ammonia, methane, and ethylene. It will also allow us to investigate the role of environment‐derived metal ions in acute gas (or solute) sensing within and between organisms. Finally, accepting O2 per se as a signaling molecule acting via gasoreceptors will open up the field of gasocrinology.
