“…The recent, short-term, heat-related abalone mortalities in Tasmania (Craig Mundy, unpublished data) and WA (Pearce et al, 2011) are likely to increase in severity and distribution (Poloczanska et al, 2007), with the effects of climate change on stocks likely to be compounded where increasing water temperatures result in a greater frequency of disease outbreaks (Vilchis et al, 2005;Travers et al, 2009). Recognizing the explicit need to develop harvest strategies and management options should these eventuate (Rogers-Bennett et al, 2010;Plagányi et al, 2011b), by following species-specific risk assessments (Pecl et al, 2011a,b), the FRDC and Fisheries Victoria have cofunded a project that will identify adaptation options to prepare these fisheries for climate change (FRDC project number 2011/039).…”

“…This has resulted in localized depletions of abalone populations (Strain and Johnson, 2009;Johnson et al, 2011). Abalone are also highly susceptible to fluctuations in water temperature (Rogers-Bennett et al, 2010) and chemistry (Crim et al, 2011), but the response varies among species (Grubert and Ritar, 2005;Vilchis et al, 2005;Diaz et al, 2006). Although climate-induced range shifts have been noted for northern and flat (H. walallensis) abalone (Rogers-Bennett, 2007), the high densities of (1) blacklip in Port Philip Bay to the south of Melbourne in Victoria and north of Sydney in NSW and (2) greenlip in Spencer Gulf, a warm, inverse estuary in SA (Nunes and Lennon, 1986; Figure 1) suggest that, over time, abalone stocks may adapt to changing environmental conditions.…”

The sustained production of abalone from the five state-managed (Tasmania, Victoria, South Australia, New South Wales, and Western Australia) Australian abalone fisheries has contrasted with many of those elsewhere that exhibited rapid and sustained declines in production. Australian abalone fisheries are significant at local, regional, state, national, and international scales. Key attributes are (1) harvesting, processing, and reinvestment of profits occur away from major metropolitan centers; (2) they are among the most valuable wild-catch species in all states; (3) the combined Australian abalone harvest in 2011 (>4,500 t) had a landed value of ∼AU$200M and represented 15% of the Australian total wild-catch production; and (4) this level of production made these fisheries the dominant contributor (60%) to global wild-catch abalone production. Unlike many other abalone fisheries, total catches were controlled by limited entry, quotas, size limits, and geographic boundaries, overseen by stringent compliance regimes, early in their history. Subsequently, state-based research programs, explicitly tasked with providing scientific advice to support management decisions, undertook assessments to match harvests with stock productivity. This information upon which to base management decisions contributed to long-term (>20 years) stable harvests and enabled relationships among stakeholders to develop around consideration of the information and advice for management. In general, rights-holders developed stewardship for the resource, and this has led to numerous important outcomes, including evolving resource co-management and a nationally representative industry entity, the Abalone Council of Australia. The Abalone Council of Australia, state-based industry entities, and ongoing relationships among rights-holders, fishery managers, and researchers play vital roles in addressing and overcoming current and impending challenges for these fisheries. These difficulties include (1) urban encroachment into coastal regions (the so-called "sea change" phenomenon); (2) a growing interest in access to the abalone resource, reflecting the increasing, culturally diverse Australian population; (3) the everpresent threat of illegal fishing; (4) recent total allowable commercial catch reductions, particularly in Victoria and New South Wales, to facilitate stock rebuilding; (5) changing market conditions; (6) declining profitability from increasing operational costs and appreciation of the Australian dollar; and (7) environmental changes, such as prolonged drought and warmer seas associated with shifts in climate. Overall, this review demonstrates that abalone can be harvested sustainably over extended periods, despite aspects of their demography that suggest higher vulnerability to overexploitation, providing the management systems that control harvesting activities and external impacts that encompass several key underpinning elements. This review also identifies likely challenges to sustained production and shows that the future of ...

Transcriptome‐wide polymorphisms of red abalone (Haliotis rufescens) reveal patterns of gene flow and local adaptation

2012

Global climate change is projected to accelerate during the next century, altering oceanic patterns in temperature, pH and oxygen concentrations. Documenting patterns of genetic adaptation to these variables in locations that currently experience geographic variation in them is an important tool in understanding the potential for natural selection to allow populations to adapt as climate change proceeds. We sequenced the mantle transcriptome of 39 red abalone (Haliotis rufescens) individuals from three regions (Monterey Bay, Sonoma, north of Cape Mendocino) distinct in temperature, aragonite saturation, exposure to hypoxia and disease pressure along the California coast. Among 1.17 × 10(6) Single Nucleotide Polymorphisms (SNPs) identified in this study (1.37% of the transcriptome), 21 579 could be genotyped for all individuals. A principal components analysis concluded that the vast majority of SNPs show no population structure from Monterey, California to the Oregon border, in corroboration with several previous studies. In contrast, an FST outlier analysis indicated 691 SNPs as exhibiting significantly higher than expected differentiation (experiment-wide P < 0.05). From these, it was possible to identify 163 genes through BLAST annotation, 34 of which contained more than one outlier SNP. A large number of these genes are involved in biomineralization, energy metabolism, heat-, disease- or hypoxia-tolerance. These genes are candidate loci for spatial adaptation to geographic variation that is likely to increase in the future.

“…Falling temperatures in the fall initiates gametogenesis in a variety of temperate chiton and worm taxa (Himmelman ; Lawrence and Soame ); sea surface temperatures did not drop in the fall of 2015 during the warm blob or in 2016 during the El Niño (Peterson et al ). In some abalone species, sperm production stops at higher temperatures (Rogers‐Bennett et al ). In the urchin Strongylocentrotus purpuratus , higher temperatures (> 17°C) for even short periods (10 d) prevent spawning (Cochran and Engelmann ).…”

To investigate the timing and intensity of winter spawning by coastal invertebrates, we enumerated embryos in plankton samples collected in daily time series from January to March of 2014 (79 d), 2015 (73 d), and 2016 (74 d). Samples were collected near the mouth of the Coos Bay estuary in Oregon. We enumerated several hundred different morphologically distinct types of embryos and larvae representing at least five phyla. Forty‐three embryo types were abundant enough (abundance > 500 over the time series) to enable statistical analysis. Twenty of these types were identified using genetic barcoding of which there were four nemerteans, four gastropods, four chitons, five polychaetes, and two echinoderms. In winter 2014, hydrographic conditions were similar to average historical values. Conditions in 2015 and 2016 were characterized by marine heat waves (MHWs). In 2015, the “warm blob”—anomalously warm water in the Northeastern Pacific—affected conditions and in 2016, there was a strong El Niño. In 2015 and 2016, winter spawning intensity was orders of magnitude lower than in 2014 and many taxa failed to spawn (11 and 24 in 2015 and 2016, respectively); spawning appears to have been adversely impacted by the MHWs. The MHW of 2015 has been attributed to anthropogenic global climate change while the 2016 El Niño may have been strengthened by climate change. The frequency, intensity, and duration of MHW are projected to increase dramatically with global warming, which may adversely affect reproduction and recruitment by numerous marine taxa.
