“…Indeed, a recent review regarding the effects of impulsive sound listed 33 invertebrate studies, with only seven of these exposing animals to realistic sound levels (Carroll et al, 2017). However, recent experiments suggest physical damage, mortality, behavioural and physiological change in scallops and lobsters exposed to airguns (Day et al, 2016, 2017; Fitzgibbon et al, 2017).…”

“…Examples of impulsive sources include air-guns used to survey the seabed for oil and gas, and pile-driving, a construction technique involving the driving of piles into the seabed during the construction of turbines, platforms, harbours and bridges. Impulsive sound exposures in field conditions may cause behavioural changes, physical damage, mortality and physiological alterations in invertebrates (Fitzgibbon et al, 2017; McCauley et al, 2017), or may have little effect at all (Parry and Gason, 2006). Since invertebrates have received much less research attention than other groups, conclusions are presently extremely difficult to draw (Carroll et al, 2017).…”

Chemical cues and signals enable animals to sense their surroundings over vast distances and find key resources, like food and shelter. However, the use of chemosensory information may be impaired in aquatic habitats by anthropogenic activities, which produce both water-borne sounds and substrate-borne vibrations, potentially affecting not only vibroacoustic sensing but other modalities as well. We attracted marine hermit crabs ( Pagurus acadianus ) in field experiments using a chemical cue indicative of a newly available shell home. We then quantified the number of crabs arriving in control versus impulsive noise conditions. Treatment (control or noise), time (before or after), and the interaction between the two significantly affected the numbers of crabs, with fewer crabs attracted to the chemical cue after noise exposure. The results indicate that noise can affect chemical information use in the marine environment, acting cross-modally to impact chemically-guided search behaviour in free-ranging animals. Broadly, anthropogenic noise and seabed vibration may have profound effects, even on behaviours mediated by other sensory modalities. Hence, the impact of noise should be investigated not only within, but also across sensory modalities. .

“…Crustacean condition or ‘vitality’ has traditionally been measured using analysis of haemolymph chemistry (e.g. lactate, glucose, glycogen levels, blood protein and haemocyanin) (Crear & Forteath, ; Harris & Andrews, ; Ridgway, Taylor, Atkinson, Chang, & Neil, ; Filiciotto et al, ; Filiciotto et al, ; Fitzgibbon, Day, McCauley, Simon, & Semmens, ). In this study there were no significant differences between total blood protein and total blood haemocyanin levels in crabs not exposed to air (0 hr, initial sample) or those exposed to air for 12 hr and 24 hr.…”

Use of reflex indicators for measuring vitality and mortality of the snow crab (Chionoecetes opilio ) in captivity

2019

The snow crab (Chionoecetes opilio) is one of the most important commercial crabs in the world; it is heavily exploited in Atlantic Canada, Alaska, the Sea of Japan and the Barents Sea. Catches in the Barents Sea north of Norway have increased dramatically in the last decade. Most of the world's catch is processed, frozen and exported overseas. However, recently there has been considerable interest in exporting live snow crab, particularly in Norway. The stress of capture and live transport can result in significant mortalities. In order to establish a live export industry for snow crab, the welfare of the animal must be monitored throughout all the steps of the live transport process. In this study the reactions of snow crabs exposed to increasing periods of air exposure were measured in terms of reflex indicators, incidence of mortality, blood lactate levels and blood protein and haemocyanin. Although this is not a specific live holding or live transport process the aim was to test the suitability of reflex indicators to reflect vitality (stress) and not just to predict mortality. This would be compared with traditional blood biochemistry techniques for measuring crustacean stress. The study demonstrated that the reflex index score (RIS) is suitable to assess the vitality of snow crab. Longer air exposure periods render higher mortality rates and less vital individuals. The authors believe using vitality reflex indicators would be a suitable way of measuring crab welfare during the live holding and transport process.

“…Haemolymph pH was measured using a Radiometer Analytical pH meter PHM210 with micro-electrode B10C162, following which the haemolymph was spun at 10,000× g for 5 min (Sigma Microcentrifuge 1-14). The supernatant was snap frozen in liquid nitrogen, stored at −80 • C and sent to Crustipath Laboratories, Canada, for analysis using a Cobas c501 automated biochemistry analyser (Roche Diagnostics Corporation, Indianopolis, IN, USA) as described by Day et al [21] and Fitzgibbon et al [22]. Sodium (Na + ), chloride (Cl − ), and potassium (K + ) were measured using an Ion-Selective Electrode, whilst Mg and bicarbonate (bicarb) were measured photometrically.…”

“…Crustacean reflex scores have been previously used to provide an accurate indicator of crustacean performance in supply chain studies [12,[17][18][19][20]. Other commonly used methods to assess lobster gross or whole-body performance include survival and nutritional condition [16,19,21,22] Physiological indicators for the assessment of the health and vitality of crustaceans commonly include immune responses (raised bacteraemia levels and changes in haemocyte counts [21,[23][24][25][26]; and haemolymph concentration of ions (e.g., potassium, sodium, magnesium, calcium, bicarbonate, pH), metabolites (e.g., ammonia, urea, glucose, lactate) and hormones (e.g., crustacean hyperglycaemic hormone) [21,25,27,28].…”

Lobster Supply Chains Are Not at Risk from Paralytic Shellfish Toxin Accumulation during Wet Storage

Lobster species can accumulate paralytic shellfish toxins (PST) in their hepatopancreas following the consumption of toxic prey. The Southern Rock Lobster (SRL), Jasus edwardsii, industry in Tasmania, Australia, and New Zealand, collectively valued at AUD 365 M, actively manages PST risk based on toxin monitoring of lobsters in coastal waters. The SRL supply chain predominantly provides live lobsters, which includes wet holding in fishing vessels, sea-cages, or processing facilities for periods of up to several months. Survival, quality, and safety of this largely exported high-value product is a major consideration for the industry. In a controlled experiment, SRL were exposed to highly toxic cultures of Alexandrium catenella at field relevant concentrations (2 × 105 cells L−1) in an experimental aquaculture facility over a period of 21 days. While significant PST accumulation in the lobster hepatopancreas has been reported in parallel experiments feeding lobsters with toxic mussels, no PST toxin accumulated in this experiment from exposure to toxic algal cells, and no negative impact on lobster health was observed as assessed via a wide range of behavioural, immunological, and physiological measures. We conclude that there is no risk of PST accumulation, nor risk to survival or quality at the point of consumption through exposure to toxic algal cells.
