“…This study produced a different interpretation of the state of egg production in the western rock lobster fishery to previous results (Caputi et al 2003;Phillips et al 2007). Downward changes in size at onset of maturity documented by Melville-Smith & de lestang (2006), which appear to be owing to a general temperature increase in the marine environment off Western australia (Melville-Smith & de lestang 2006), or a genotypic response to size-selective fishing pressure (Allendorf et al 2008;Melville-Smith & de lestang 2006) were not taken into account in previous estimates of egg production.…”

Size at maturity in the western rock lobster (Panulirus cygnus) fishery in Australia increases from north to south and female lobsters carry either one or two batches of eggs per season depending on their carapace length. There has been a steady decrease in the size at first maturity of western rock lobster over the last 30 years, and there are now significantly more small females, many below the legal minimum size, contributing to the brood stock than any time since the fishery has been researched. Biological data were used to show the current contribution to egg production in different management regions of the fishery and historical length-frequency data were used to show how egg production has changed in those regions overtime. Reasons for the change in size at maturity in this fishery are unclear, but the outcome has been that egg production is now more evenly distributed across management zones. Egg production was high at Abrolhos Islands in the 1990s owing to strong year classes of breeding animals entering the fishery over those years. In the period since 2000, egg production has fallen sharply at the islands, but has increased in the coastal population compared with the 1980s and 1990s.

“…ater has a significantly higher growth rate in sheltered sites, changes in the sea level that would impact the physical habitat of the mussel bed may favor A. ater, although one may argue that predation is likely to be more intense at sheltered sites. The rock-lobster is another predator that is particularly sensitive to environmental factors such as water temperatures, strength of the Leeuwin Current, and westerly winds [62,63]. The scarce distribution of A. ater at Malgas Islands is indeed attributed to intense predation by rocklobsters [64].…”

The sedentarism and wide global distribution of the blue musselMytilus edulishave made it a useful bioindicator to assess changes in the health status of the marine ecosystem in response to pollution and other environmental stresses. Effective biomonitoring of an ecosystem requires, however, that multiple biomarkers be used to obtain an accurate measure of the cumulative effects of different sources of environmental stress. Here, we provide a first integrated review of the biological, economical, and geographical characteristics of another species of mussels, the ribbed musselAulacomya ater. We discuss the use ofAulacomya ateras a complementary biomonitor to the blue mussel to assess the impact of pollutants and climate change. Recent findings have indeed shown thatMytilus edulisandAulacomya aterhave distinctive anatomy and physiology and respond differently to environmental stress. Monitoring of mixed beds containing blue and ribbed mussels may thus represent a unique opportunity to study the effect of environmental stress on the biodiversity of marine ecosystems, most notably in the Southern hemisphere, which is particularly sensitive to climate change and where both species often cohabitate in the same intertidal zones.

“…This method uses an index of juvenile and puerulus abundance (the last larval stage and first demersal stage of lobster) in numerical models to provide an early warning of catch declines, and allow catches to be predicted up to four years ahead (Caputi et al, 1995;Caputi et al, 2001). This predictive method was developed for the management of the P. cygnus fishery in Western Australia and it is based on the close relationship between recruitment patterns of the puerulus stage (i.e., the first postlarval stage that assumes a benthic habit) and the future recruitment of legal size lobsters into the fishery (Caputi et al, 2001;Caputi et al, 2003;Melville-Smith et al, 2004). The recruitment and abundance of puerulus are incorporated into stock assessment models to adjust TACs of this fishery and reduce the risk of further declines in the stock.…”

reduction in the biomass of adult lobster biomass after 20 years (i.e. by 2025). In general, the model predicts that the variations in lobster biomass, whether induced from fishing mortality or declining puerulus settlement, have relatively small effects on the biomass of the main predators and prey of lobster in the marine park. The relative biomass of adult rock lobster and their associated predators and prey was more sensitive to fishing than to variations in recruitment.
