Sub-lethal behavioural and physiological responses to an underwater explosion in two crustacean species.
The impacts of a small, free-field, surface explosion from a ship scuttling, on two crustacean species was examined. The southern rock lobster (Jasus edwardsii) and the spotted shore crab (Paragrapsus gaimardii) were used to compare the effects on crustaceans in a controlled experiment on animals distributed up to 500 m from the blasts. Methods for assessing damage included; mortality, behavioural experiments, and physiological assessments.

- Statement
- In order to examine the sub-lethal effects of seismic blasts on crustaceans, the project used two decapod crustaceans, the southern rock lobster (Jasus edwardsii) and the spotted shore crab (Paragrapsus gaimardii). Four life-history stages of the rock lobster (adult, juveniles, puerulus, phyllosoma) were examined. Seventy five adult Southern Rock Lobster (Jasus edwardsii) were collected using pots in the Taroona Reserve (42o57’07.26”S, 147o21’21.73”E) in early January. They were individually tagged using numbered cable ties around their antennae. Lobsters were fed three kg of mussels once a week for the four weeks before the explosion. Juveniles, puerulus, and phyllosoma were sourced from captive broodstock held in the aquaculture laboratories at MRL. All animals were held in flow-through tanks at ambient conditions until mid-February when the Troy-D was scheduled to be scuttled. The vessel “TROY D” was positioned over sandy substrate over 28 m depth, 1 km off Maria Island, 42o36’27.81”S, 148o00’57.40”E. It was scuttled on the 10th February 2007 at 11:30 am using four linear cutting charges. The animals were positioned on the port side only, in a transect extending from one of the cutting charges. Nine stations were set up on seven buoy lines. These stations were positioned 1, 5, 10, 20, 100 and 500 metres away from the explosives on the ‘Troy D’. Each station consisted of a large nylon 0.6 cm size mesh bag (1.2 metres x 0.6 metres) which contained 8 adult lobsters. Inside the large bag, 10 juvenile lobsters and 10 crabs were held in separate laundry bags, 10 puerulus were held in small organza bags, and 100 phyllosoma larvae were held in 200 ml plastic specimen jars with 0.2 cm size mesh lids. Animals were positioned on the surface of all sites and on the bottom at the 5 metre and 20 metre site. At 500 m from the blast, the pressure from the explosion had attenuated to 0.003 MPa. Mortality of all animals was measured immediately after the blast, and every 24 hours after that for seven days. A range of response variables were used to measure any post-explosion sub-lethal changes in behaviour and physiology which may increase susceptibility to predation or reduce foraging ability. All variables were measured on lobster adults, juveniles, puerulus and shore crabs 7 days before, immediately after and 7 days after the explosion. Lobsters were measured at random and as quickly as possible to reduce stress from handling and immersion. Recorded the vitality (using tail gape and tail flip count), escape response (using threat stimuli) and orientation (balance, time taken for the animal to right itself) for both species. Behavioural data was measured one week before, immediately after and one week after the explosion. Additional physiological data was recorded by determining damage to the statocyst using Scanning Electron Microscopy (SEM).
